That why I love my tier 3. No def, dpf, or cat. One small puff of smoke when it fires up and she burns clean. I’ll also keep my 03 duramax. No emissions no problems
I have the kabota l 39 0 1 and I was unfamiliar with this system, The dealership where I purchased it didn't really go into detail like this about it and when I ask them for more info they were very vague I'm grateful I found this man thank you very much for your assistance you just save me a hell of a heartache.
Love your videos Neil! But I gotta say the emissions crap on my M7060 is a pain in the ass! You can down play it and I understand why. Main problems I have experienced... Any time a regen is needed when not working in a high RPM manor (mowing or bailing) it's a big inconvenience. Most time I have to stop what I'm doing and leave the tractor parked running at wide open RPMs for 20 minutes or so and have to keep coming back to check to see if it's finished. This is a waist of time, fuel and engine hours. Also I've experienced roughly a 25% loss of fuel economy with this tractor over my previous (non-DPF) M7040. The lead tech at my Kubota dealer said the DPF system chokes these motors so much that without it I'd have about 30 more HP. Then there's the added components an complexity the system adds. All to keep a little soot out of the air. The on-road trucking industry is really having trouble with these systems. It's been real nightmare for them. These types of regulations are costing us in untold ways.
Don't feel bad our M8560 in the winter wants to Regen almost every time I go to use it. We use it for some loader work in the winter, in the summer I never notice it because it gets worked hard enough for the auto Regen to do it's thing. So annoying.
Any emissions savings go out the window when these engines die a premature death and are shipped off to the third world to be smelted down in a circa early 1900's blast furnace.
I worked as a diesel mechanic up until a few years ago. The dpf and def systems were our #1 problem. Given time, they become problematic. That's just my experience with a fleet of 120 tractors.
DOC only engines are on most of the imported brands. The more domestic companies (Kubota & Deere) are using DPF's. A large part of this is probably because at Tier 5 DOC-only likely won't be complaint requiring companies to do a lot of model updates.
The more I research new 50 H.P. tractors, The more apprehensive I get a bout purchasing one. The Dailey , hourly, weekly, seasonal and preventative up keep, maintenance and attention seems . . . . Ardouos . Am glad you are teaching all this stuff you have many great vids. The internet is a better place because of you and Adam at Hometown. Thanks for your time and effort.
Another fantastic video. I have a smaller tractor (John Deere 1026r) and was watching a few reviews on larger tractors I was considering... and came across where one of the topics was "Regen cycle" I had no clue what they meant... came across your video and you explained it fantastic! thanks again for all the great videos!!!
It wouldn't be so bad if they released the software so you could hook the laptop up to the tractor without having to call the service department. Tier 4 is a nightmare. I love the idea of cleaner emissions, i hate the fact that it made doing certain repairs dealer only. Dealers probably love it because it means more revenue through their service department.
William Todd we have a Kubota m7060 that has almost 3 thousand hours with all the emissions stuff and we haven’t had a problem yet we also have a l3560 with 500 hours that has 500 hours problem free tractors with this don’t have enough age to know how this stuff will last
Nope sawzall took care of that. Drove it around for a few months as it was, then removed the cat when I replaced the engine and transmission and turned it into a work truck.
Runs much better less exhaust resistance for a better flow actually increases your HP and your fuel economy. Maybe do some research before opening your mouth.
I bought a new B2650 instead of the 3350 because of this. Now I’m wanting an additional larger tractor. Looks like I’ll just keep my older model! However, I always enjoy your videos. Keep up the good work!
I heard somewhere that the best thing to with a dpf for cleaning is to do some long hours of heavy use like mowing out a big field with the revs up or driving in a low gear to get around
Good job explaining the fliter. I'm sticking with pre- emissions tractors. Heck I still have gas tractors making hay and moving snow. The start nice in the winter. Refurbish a older tractor you'll be happier
@Bill I bought a L2501 in january this year but kept my 1950 8N as it has no trade value and is worth more to me as a second tractor. I picked the L2501 because the next one up on the same frame size had all that "stuff" and it is hard enough keeping up with my over the road vehicles.
You make subscribing to this channel worth it. I have the alerts on when you publish a new video. And I'm not even on the market for a compact tractor ;-) TYFS
Ahhh, DPF explained - clearly. Thank you. Once I understood the burn system logic on my B3350, my concerns drifted away. If you ever open a branch office in Colorado, you'd get my business, specifically because of your educational videos.
FYI One advantage of owning a Mahindra, They invested $30 million to redesign their diesel engines where DPF aren't needed and Regen isn't needed either. Now with that said Messick Farm Equipment's service sounds like it something that might swing me towards a Kubota if I was depending on them for service, Our Kubota dealer isn't near as customer service orientated. And I do appreciate the three minute instructional videos
This seems to be a popular misconception. 30 million is a pittance in engine design, any time you hear of engine design costs your usually talking multiple hundreds of millions. What Mahindra 'designed' was a DOC-only engine system, which is not really their technology. Virtually every engine manufacturer offers a DOC-only engine, many tractors companies use them. They don't have anything special. I think I talked a bit about Doc-Only in this video. All that said, Mahindra does not build 2/3 of their tractors and simply buys them from TYM or Mitsubishi. They talk about this investment as if it applies to all models, but reality is it would only be on the handful of models they build themselves.
I'm fully aware that Cummins developed the DOC technology. (Been in the trucking industry for 40 years and I'm the Business editor for a national trucking Magazine.) In my research from the Trucking side, DEF Filter engines are a royal pain. So when I researched purchasing a new compact tractor the regen of the DEF system was a major concern. As you pointed out when the engine is doing a regen it must be run at a high rpm. If I'm tilling or operating other 540 PTO rpm equipment like spraying or mowing I don't have the option of allowing a higher rpm than the one that maintains my pto at 540 rpms so continuing to work would not be an option as tractor land speed and pto rpm are extremely important. Frankly, DEF technology was developed in a rush by the diesel engine mgfs to fulfill emission requirements with the lowest development cost, and on the trucking side DEF system failure the most frequent event that puts semis on the side of the road. Since my farming is tightly scheduled between my other occupations and responsibilities, and my knowledge of the problems of DEF systems within the trucking industry, I would have purchased a pre-DEF used the tractor if this DOC technology wasn't available. And while Mahindra didn't invent DOC, they have designed a new engine to use this technology very effectively. With that said everything has it gives and takes. and as I use the Mahindra I will come to know the downsides and the upsides of this purchase. The main thing that I advise any truck owner when purchasing a truck is the most important part of your purchase is the quality of the dealer who will handle warranty, maintenance, and repairs, so chose where one buys wisely. That is the other reason I Chose the Mahindra, as the local Kubota and John Deere dealers lack that commitment to customer service I require. I'm pretty sure from what I have seen in your videos and online reviews, If I lived near Messick Farm Equipment, I would be seriously looking at you as a place to purchase, maintain and repair my farm equipment. Thank you for your informational videos they are helpful and beneficial.
Yikes. An EGR valve on a gas engine is a bad idea because of soot and goop. I can't imagine an EGR on a diesel engine. Asking for trouble if you ask me.
another great video Neil; couple things to include: one thing is to try to always run your tractor at the 2000 rpm and above range (near where the tachometer needle will line up with the 540 rpm pto indicator), the engine is made for it, and it's not going to hurt anything; in fact running it to low will probably do more to wear things out; hydraulics and everything else on these tractors is set up for running at the higher rpm's; running it at the correct rpm will also make re-gens less frequent as the DPF is in its heat range to keep itself clean. one thing you should include is a warning to move your tractor out of the tall grass before starting a re-gen. the exhaust temp does go way up if the DPF is really dirty and with the lower mounted exhaust there is a possibility of starting a fire. i will see if i can get a exhaust outlet temp reading next time my MX4800 is in re-gen. for those that don't know: there is also two buttons on the dash: one to start a re-gen, and one to postpone a re-gen. it is advised to let a re-gen run whenever possible. my local Kubota dealer says the biggest problem is inexperienced operators that keep hitting the cancel button, and as Neil explained eventually the computer won't let you do anything.
Yeah... run the hell out of the engine constantly... lol. It's "made for it". Naw... they just threw a soot cooker in there and piped exaust into the intake.
Yeah. And there is definitely a reason for warm up and cool down. Instead of keeping your expensive engine happy, now you keep the soot cooker happy. It's a bad idea that got forced on us by people that don't know anything about it.
For anyone hesitant to purchase a smog controlled ECU equipped Tier4 tractor, I can say after about 5 years of running 6 Kubota L4060 tractors similar to this one, we have had no problems with the smog control devices. This is in a Rental fleet, so no shortage of abuse or neglect there. The regen procedure is quite simple and with the PM percentage gauge on the dash it is easy to tell when a burn off is imminent. There is the potential for customers ignoring the warnings enough that the dealer has to force a regen, but that has only happened once and with no ill effects. Overall, these newer electronic engines are smoother, quieter and have been tougher than our old L3530 and L3940 machines.... which while good simple tractors, were also prone to being harder to start cold as they aged, and could be blown up by a very abusive/neglectful customer who ignored the temps while say, mowing a dry field. ECU control and emergency shutdown has meant none of our machines have been popped yet, after an average of 1500hrs. That aspect alone makes the added complexity of the EGR/DPF well worth it, just to gain modern electronic monitoring and diagnostic abilities.
Neil, during a regen diesel fuel is injected into the engine on the exhaust stroke, in addition to the usual intake stroke. Fuel injected on the exhaust stroke does nothing to keep the engine spinning but rather flows right down the exhaust into the DPF tube. It is a convenience method of injecting fuel for a regeneration vs using an additional injector in the exhaust system. So during a regen, yes...extra fuel is used! And during that time, fuel consumption is significantly higher! Running at high RPM helps increase heat, but the diesel fuel is needed to significantly increase heat in the DPF...otherwise, regeneration would occur naturally at high RPM. FYI...Kubotas with a DPF also have a DOC and EGR as well! The DOC is what converts the unburned diesel fuel into heat for the DPF. EGR is used actually to cool the exhaust stream to reduce NOX to an emissions-acceptable level. Higher horsepower machines require DEF injection for this purpose as well. Lots of EGR is not good for an engine because EGR gas is “dead” gas that can over time coke up the intake valves and EGR system itself. It’s also worth noting that a regeneration system using exhaust-stroke injection can and likely will cause engine oil to be diluted with diesel fuel because of natural blow-by. The amount is small and this is a normal condition but it underscores the importance of regular oil changes. Finally, the reduced diesel “smell” is more the result of tightly controlled direct injection than a DPF. Older tractors had mechanical, indirect injection which were totally reliable but at times injected too much fuel (under peak load or at startup) which caused black smoke to emit). The DPF will certainly be a health benefit to an operator, however...because carcinogenic PM that you might breathe is now captured. My experience with current day DPF and other exhaust aftertreatment systems is that they are generally problem free but certainly add to the cost of a machine.
Hi Neal, good video, it should answer a lot of questions that people have. I have a L47 TLB which has the DPF percentage screen that I always have on display. It's nice to know when a regen is nearing. I usually run about 2000 rpm's, and burn about every 30 hours. At lower rpm the percentage increases quickly. I've also noticed if I run it at higher rpm and work it hard enough the percentage will actually decrease. Enjoy the videos, keep up the good work.
New to the DPF world... Brand new L4802.. I thought low RPM would save engine wear and tear... been moving some logs around, pretty much under 1000 RPM... DPF came on at 16 hours... So, what is a good operating RPM when not using the PTO? I don't want to be to low due to DPF and not to high to run it in the ground... Please advise!
@@michaelhenderson6312 Sorry about the errored reply. I run mine around 1800 rpm doing most jobs. Don't worry about wearing the engine out, with proper maintenance it will last a lifetime.
I dont know about tractors but trucks the doc and dpf work together. The doc is first an injector injects fuel into exhaust that reacts with the doc to raise the temps to cook the soot out off of dpf
hmmmm , so there is a carbon cost to build this regen system, mine the metals-shape them-make filters-build into tractor-fuel spent in burn off etc. and you will need to buy a new one which leads to carbon cost of you driving to dealer and it being delivered to you. Meanwhile the fire dept. in Youngstown Pa. does not extinguish abandoned home fires which each generate more carbon than all of you and your friends tractors will generate in your lifetime!!!!! Thank you smart government thinktanks
I find this funny. I was working with a friend of mine who has a new Kubota he had to stop every 20 minutes or so while I ran my old Ford kept going all day. we were both running at almost full throttle heavy loads he's taken her back to fix it at least 3 times. I think I will keep my old Ford. It's not up to date and could use a rebuild, but she still runs. And I can rebuild her myself. I just need the time.
100% agree with @chuckquinn8026, you have a way of explaining the subject that common folk understand COMPLETELY without the drama and overacting the majority of you tube videos do!
My diesel truck always seem to start a regen when pulling up in my drive way. Most of the time I did not get a regen message I would see the mileage drop from 16 to 8 MPG. It would be nice to read the DPF pressure and start a regen at a more convenient time
When did DOC and DPF first show up on S.S. sold tractors? Am I correct in believing that they are a Great Big N?A on an '05 NH TC33DA? I think that my money would be better spent on a total rebuild at 3000 hours than on a replacement. With 2500 hard hours and minimal maintenance she is getting kind of tired - especially the hydraulic pump. sdh in the Tobacco Valley of CT (GrunderLand)
My L3560 has done 3 regens at around 23, 24 hours between each one. Normally run it 1500 to 2000 rpms unless working it where it needs more. Should I run higher rpm all the time?
Is the exhaust on the L3301 (with DPF) "cleaner" for the operator to breath then the L2501 (without the DPF) or is it only an environmental thing? When working with tractors, your going to be breathing a lot of that exhaust. Thanks!
I did construction and for our heat in the winter and heat our tar we ran our trucks and the trucks had the dpf and the i would get sick but our one trk had been deleted and i could be standing right next to ot just like my old gm 6.5 or now my 7.3 ps and not be bothered by it
300-500 dollars to get the DPF cleaned out...NOT. Dad took his Kubota to the dealership in West Memphis(not mentioning names) to get the DPF cleaned out....$2000 bill. That’s all that was done. To say he was PO’d would be an understatement.
Not sure on kubota but otr trucks you can wash out your own dpf, need new gaskets etc but you still need the oem software to reset the cleaned parameter or the code still cannot be cleared. Ahh, isn't the epa great. Said no same man evah!
Mahindra doesn’t have DPF, Massey is coming out with tractors that don’t have DPF as well. I like kubota but I will buy a low hour used machine to avoid the extra potential for issues. Great video Neil.
That's the DOC system I talked about. It has it's own intricacies. 🚜 Kubota also makes DOC only engines, they just don't seem to think they are appropriate for tractor applications.
Hey Neil, this is not related to this video, but would you be able to do a side by side comparison with the Kubota BX23S to the New Holland workmaster 25s? Thought it might make a good video, both tractors look nice. Thank you.
Did the rgen issues with the b3350 get sorted out because I am thinking about buying one used. What should I look for. And is all service bulletin tracked by the serial number of the tractor. Thank neil
Mi Heating Guy I am using a 2014 B3350 with all the updates on it. Last summer it ran great, and never had an issue. Once our fuel supplier switched to winter diesel it would fail about 15 minutes in, then once it cooled it would complete a regen and be fine until the next regen. Now that I’m back on summer fuel, it is doing fine again. That said, my dealer informed me that it could be due to a possible timing issue of the fuel pump, and they are working with Kubota to solve the problem. I would still buy the tractor knowing what I know now, and I am confident my issues will be solved soon.
Mahindra's marketing is maybe one notch above politics. That's a DOC-only engine, also used by a half-dozen other companies. Same thing as a DPF but rather than running a cycle every 20-40 hours its always running hot and burning continuously. There are pro's and con's to any of these engine systems. The con's on this system is more use of EGR (exhaust recirculation), overall higher engine temp's, and warm up \ cool down periods before and after you operate. I've heard other Mahindra dealers refer to this as a "no emissions" engine, that's simply not truthful .
Better to try to get the tractor working when during the Regen process. Have this on the firetruck I drive. Run enough on the highway and don't have to go through the cycle at the station.
Fire trucks and ambulances have different "shut down rules" than typical on road diesels, and they should. The regen software is similar. Years ago the soot went into the atmosphere and noone made money on the exhaust. Today the exhaust is filtered, collected and then washed into our water system, an entire industry makes money and the epa collects more money if u don't comply. The same pollution is there just more expensive.
It'll be decades before anybody really knows. The stuff is far from new at this point, but the last couple of generations of equipment just don't have the age to them yet.
What is an appropriate rpm to run an L3901? I have 67 hours and have had 3 regens(16, 32 & 59 hrs). The third regen was done during snowblowing season where pto rpm was used all the time. I don't want to run 2300 for normal use,though.
My L6060 is at 91% full (22.4 hrs on the tractor) and has not asked for a regen, my dealer said to let it go to 100% and see what happens. That sounds pretty risky to me ???
One comment you need to say on DPF is use of engine oil. My Kubota Dealer drove 60min out to do a on farm first service with wrong type of oil(kubota CH-4 Oil). He did not know my tractor had a DPF until i point it out. If I did not pointed out and call back to based. I would have had Kubota CH-4 oil in the Engine. What would happen i did not put in correct oil to engine? Lucky he had some Isuzu DPD Approved oil. but not still not CJ-4 oil. But they say they use that oil in DPF equip Kubota..
Likely nothing bad. Owning a diesel car shop I've seen many clients running well over 100K on CJ4 oils with not DPF issues. Modern oils are really low in the "bad" stuff that kills the DPF. The CJ4 is even lower still.
No I don't think. We pay several thousand a year for the licenses and adapters. It's really expensive stuff. Other than making neat charts, I've never seen anything in there of value to an individual owner. I do follow right to repair and consider myself a supporter of it.
@@MessicksEquip The main reason for soot is Ethier to much fuel or the engine is not up to working temperature / Excess idling to keep the soot burn off If it was me I would have an ECM setup that would read the EGT when idling and throttle the engine up to working temperature to burn the soot off and throttle back down according to the EGT the electric cooling fans work similarly to that but I'm not and electrical or a software engineer I was taught never let a diesel set idling for extended periods and to let the engine idle 5 minutes if its turbo charged after being worked hard to prevent wet stacking and coking in the turbocharger oil lines!
the manufacturer spends millions of dollars developing the system, sensors, hardware to get all this epa mandated crap to run. they are liable if it works incorrectly ( ask Volkswagen) so if you have not attended factory training and have factory authorization- serious doubts they will sell you any software. it's a catch 22 situation if there ever was. I don't see apple selling software to fix their devices and they don't have the epa leaning over their shoulder. not saying some tiny company cant develop their own to sell- that's another story.
Apple doesn't want anyone working on their electronics, but go get a proper computer. You can download the service manuals for all thinkpads for free, which shows ever screw, part number, option, and all the correct specs. They learned to be successful with giving consumers the information to repair everything, so why can't other companies?
@@firstname6208 They should be made to have the software available for people to make repairs, They arent liable for someone who isn't employed by Kubota using software.. Just like Apple isn't Liable if i activate a bomb with my iPhone
I have a M6060. My owners manual says that when the Regen symbol comes on you should place it in Park and the computer will automatically raise the engine speed. This never happens. I have to raise the throttle myself and eventually the light will go out.
Hey Neil, I have a M135GX. I done many regen so far on the tractors. Is there an option with out a computer to start a regen early? Ie at 90%. My first regen request was like 1min before shutdown for the night at 11pm, I had to inhibit it and do a regen next time(a month later) i started up. But if in knew i have hour before shutdown i can do a early regen and get the filter clean out. Also can you do a video on Diesel performance chips. Or how to save fuel. My M135GX drinks a tanker load more of diesel vs the M125X it replaced under the same condition. I feel like my local fuel station is becoming my best friend and my plastic is getting paper thin.
I’m sorry but the fuel used to ReGen doesn’t seem Eco-friendly. Has anyone independently done analysis to see what is the real gain of the DPF ? EPA emissions trash causes problems which seem counter productive and further environmental impacts.
if you are out working the tractor hard- when requirements are met- it will (should) do it automatically. if you know it is in the middle of a regen and you have finished your work- allow the regen to complete before shutting down or the regen will not give credit and you will not return to zone zero which means you still need the regen.
And running the tractor at redline for 25-30 minutes when it doesn't have to doesn't consume more fuel?? What??? And on top of that even more fuel is being dumped in on the exhaust stroke. Multiply this by MILLIONS of tier 4 final tractors and trucks....that "small amount of fuel" adds up quickly....in the end, oil companies pocket the extra cash and the environment still suffers. And let's not forget dealers who make thousands in profits a year fixing this unreliable garbage and even more replacing blown up engines and bent connecting rods from leaking EGR coolers. Absolute theft.
Jason Daniels I can see the benefit of emissions equipment on professional/contractor equipment. They run multiple pieces of machinery for for thousands of hours per year and that much pollution can add up. These professionals can absorb the added cost as overhead for the maintenance and downtime emissions equipment inevitably causes. Landowners and hobby farmers don't need the headaches, complexities or costs and have far less environmental impact.
If Kubota honors warranty after dpf delete I would buy their tractor. I owned 3 semi trucks. One hate dpf+DEF system Maitenance nightmare. One had EGRs again problems. The last truck no emissions 1999 Volvo n14 best truck I own
In trucks DOC burns the stuff then DPF filters it and SCR w/ DEF gets rid of NOX (over simplified) I work in the med and heavy duty truck industry. DOC, DPF, SCR, and DEF system all equals money and more down time. Fuel economy went down for trucks. Exhaust is a lot cleaner and smells better and its the law. DONT skip your regens!!!
Your opinion that it smells better . I'll take regular Diesel exhaust any day. Besides , the over the road trucks I drive CONTINUALLY have emissions problems . Biggest bunch of crap ever . Thanks EPA ! 😡
$4k SCR $1k DPF $2K DOC and all the sensor and inj. Its around $10k system. Yes nothing but trouble AND egr system is not good for the engine more problems
Kubota should be paying you for your training video’s. Always clear and precise. Thanks Neil!
I bet they do pay him, he of course wont tell you because its not in his interest financially.
I'd rather buy an older machine without DPF. Nice video! Thanks Neil 😊
That why I love my tier 3. No def, dpf, or cat. One small puff of smoke when it fires up and she burns clean. I’ll also keep my 03 duramax. No emissions no problems

Appreciate the information Neil, thank you for sharing this information, I greatly appreciate it! Watching and Supporting - LIKING another video!
It wouldn't be so bad if they released the software so you could hook the laptop up to the tractor without having to call the service department. Tier 4 is a nightmare.

Best thing to do is buy an older tractor before they added that crap.
William Todd we have a Kubota m7060 that has almost 3 thousand hours with all the emissions stuff and we haven’t had a problem yet we also have a l3560 with 500 hours that has 500 hours problem free tractors with this don’t have enough age to know how this stuff will last
did you stop buying cars because of catalytic converters?
Nope sawzall took care of that. Drove it around for a few months as it was, then removed the cat when I replaced the engine and transmission and turned it into a work truck.
That's really ignorant. And removing cats from a vehicle? And somehow you think it'll run better? Wow....
Runs much better less exhaust resistance for a better flow actually increases your HP and your fuel economy. Maybe do some research before opening your mouth.
Thank you, I did not realize you could continue working during the cycle.
Excellent topic. Thank you.
I bought a new B2650 instead of the 3350 because of this. Now I’m wanting an additional larger tractor. Looks like I’ll just keep my older model! However, I always enjoy your videos. Keep up the good work!
Thanks for the information much appreciated.
Great explanation
Great info, enjoy the videos.
I heard somewhere that the best thing to with a dpf for cleaning is to do some long hours of heavy use like mowing out a big field with the revs up or driving in a low gear to get around
Good job explaining the fliter. I'm sticking with pre- emissions tractors. Heck I still have gas tractors making hay and moving snow. The start nice in the winter. Refurbish a older tractor you'll be happier
Great info!
Great video.
Great information, thanks
You have a laptop on a tractor just think about that....I’ll just buy a pre emissions one thanks .
Laptops have been used on tractors far longer than that.
Good luck finding one without this bullshit on it
@Bill I bought a L2501 in january this year but kept my 1950 8N as it has no trade value and is worth more to me as a second tractor. I picked the L2501 because the next one up on the same frame size had all that "stuff" and it is hard enough keeping up with my over the road vehicles.
You make subscribing to this channel worth it. I have the alerts on when you publish a new video. And I'm not even on the market for a compact tractor ;-) TYFS
Ahhh, DPF explained - clearly. Thank you. Once I understood the burn system logic on my B3350, my concerns drifted away. If you ever open a branch office in Colorado, you'd get my business, specifically because of your educational videos.
Thanks for explaining this. Wish people didn’t have to do this. Oh well I guest this is why the old ones are so expensive.
FYI One advantage of owning a Mahindra, They invested $30 million to redesign their diesel engines where DPF aren't needed and Regen isn't needed either. Now with that said Messick Farm Equipment's service sounds like it something that might swing me towards a Kubota if I was depending on them for service, Our Kubota dealer isn't near as customer service orientated. And I do appreciate the three minute instructional videos
This seems to be a popular misconception. 30 million is a pittance in engine design, any time you hear of engine design costs your usually talking multiple hundreds of millions. What Mahindra 'designed' was a DOC-only engine system, which is not really their technology. Virtually every engine manufacturer offers a DOC-only engine, many tractors companies use them. They don't have anything special. I think I talked a bit about Doc-Only in this video. All that said, Mahindra does not build 2/3 of their tractors and simply buys them from TYM or Mitsubishi. They talk about this investment as if it applies to all models, but reality is it would only be on the handful of models they build themselves.
I'm fully aware that Cummins developed the DOC technology. (Been in the trucking industry for 40 years and I'm the Business editor for a national trucking Magazine.)
In my research from the Trucking side, DEF Filter engines are a royal pain. So when I researched purchasing a new compact tractor the regen of the DEF system was a major concern. As you pointed out when the engine is doing a regen it must be run at a high rpm. If I'm tilling or operating other 540 PTO rpm equipment like spraying or mowing I don't have the option of allowing a higher rpm than the one that maintains my pto at 540 rpms so continuing to work would not be an option as tractor land speed and pto rpm are extremely important.
Frankly, DEF technology was developed in a rush by the diesel engine mgfs to fulfill emission requirements with the lowest development cost, and on the trucking side DEF system failure the most frequent event that puts semis on the side of the road. Since my farming is tightly scheduled between my other occupations and responsibilities, and my knowledge of the problems of DEF systems within the trucking industry, I would have purchased a pre-DEF used the tractor if this DOC technology wasn't available. And while Mahindra didn't invent DOC, they have designed a new engine to use this technology very effectively.
With that said everything has it gives and takes. and as I use the Mahindra I will come to know the downsides and the upsides of this purchase. The main thing that I advise any truck owner when purchasing a truck is the most important part of your purchase is the quality of the dealer who will handle warranty, maintenance, and repairs, so chose where one buys wisely. That is the other reason I Chose the Mahindra, as the local Kubota and John Deere dealers lack that commitment to customer service I require.
I'm pretty sure from what I have seen in your videos and online reviews, If I lived near Messick Farm Equipment, I would be seriously looking at you as a place to purchase, maintain and repair my farm equipment. Thank you for your informational videos they are helpful and beneficial.
Yikes. An EGR valve on a gas engine is a bad idea because of soot and goop. I can't imagine an EGR on a diesel engine. Asking for trouble if you ask me.
another great video Neil; couple things to include:
one thing is to try to always run your tractor at the 2000 rpm and above range (near where the tachometer needle will line up with the 540 rpm pto indicator), the engine is made for it, and it's not going to hurt anything; in fact running it to low will probably do more to wear things out; hydraulics and everything else on these tractors is set up for running at the higher rpm's; running it at the correct rpm will also make re-gens less frequent as the DPF is in its heat range to keep itself clean.
one thing you should include is a warning to move your tractor out of the tall grass before starting a re-gen. the exhaust temp does go way up if the DPF is really dirty and with the lower mounted exhaust there is a possibility of starting a fire. i will see if i can get a exhaust outlet temp reading next time my MX4800 is in re-gen.
for those that don't know: there is also two buttons on the dash: one to start a re-gen, and one to postpone a re-gen. it is advised to let a re-gen run whenever possible. my local Kubota dealer says the biggest problem is inexperienced operators that keep hitting the cancel button, and as Neil explained eventually the computer won't let you do anything.
Yeah... run the hell out of the engine constantly... lol. It's "made for it". Naw... they just threw a soot cooker in there and piped exaust into the intake.
That is literally what a DOC only engine is...funny enough
Yeah. And there is definitely a reason for warm up and cool down. Instead of keeping your expensive engine happy, now you keep the soot cooker happy. It's a bad idea that got forced on us by people that don't know anything about it.
For anyone hesitant to purchase a smog controlled ECU equipped Tier4 tractor, I can say after about 5 years of running 6 Kubota L4060 tractors similar to this one, we have had no problems with the smog control devices. This is in a Rental fleet, so no shortage of abuse or neglect there. The regen procedure is quite simple and with the PM percentage gauge on the dash it is easy to tell when a burn off is imminent. There is the potential for customers ignoring the warnings enough that the dealer has to force a regen, but that has only happened once and with no ill effects. Overall, these newer electronic engines are smoother, quieter and have been tougher than our old L3530 and L3940 machines.... which while good simple tractors, were also prone to being harder to start cold as they aged, and could be blown up by a very abusive/neglectful customer who ignored the temps while say, mowing a dry field. ECU control and emergency shutdown has meant none of our machines have been popped yet, after an average of 1500hrs. That aspect alone makes the added complexity of the EGR/DPF well worth it, just to gain modern electronic monitoring and diagnostic abilities.
You can get computer controlled safety features without unnecessary emissions systems
Neil, during a regen diesel fuel is injected into the engine on the exhaust stroke, in addition to the usual intake stroke. Fuel injected on the exhaust stroke does nothing to keep the engine spinning but rather flows right down the exhaust into the DPF tube. It is a convenience method of injecting fuel for a regeneration vs using an additional injector in the exhaust system. So during a regen, yes...extra fuel is used! And during that time, fuel consumption is significantly higher! Running at high RPM helps increase heat, but the diesel fuel is needed to significantly increase heat in the DPF...otherwise, regeneration would occur naturally at high RPM. FYI...Kubotas with a DPF also have a DOC and EGR as well! The DOC is what converts the unburned diesel fuel into heat for the DPF. EGR is used actually to cool the exhaust stream to reduce NOX to an emissions-acceptable level. Higher horsepower machines require DEF injection for this purpose as well. Lots of EGR is not good for an engine because EGR gas is “dead” gas that can over time coke up the intake valves and EGR system itself. It’s also worth noting that a regeneration system using exhaust-stroke injection can and likely will cause engine oil to be diluted with diesel fuel because of natural blow-by. The amount is small and this is a normal condition but it underscores the importance of regular oil changes.
Finally, the reduced diesel “smell” is more the result of tightly controlled direct injection than a DPF. Older tractors had mechanical, indirect injection which were totally reliable but at times injected too much fuel (under peak load or at startup) which caused black smoke to emit). The DPF will certainly be a health benefit to an operator, however...because carcinogenic PM that you might breathe is now captured.
My experience with current day DPF and other exhaust aftertreatment systems is that they are generally problem free but certainly add to the cost of a machine.
Your correct, I think I explained most of those details but not to the extent you did... Except for EGR, there is no EGR on these engines.
great video
I'm glad my B2650 doesn't have to do that.
What is the largest kubota tractor without the emmission standards that everyone is concerned about ?
L2501, but the concerns are 1000% over blown. As anyone who owns one.
Hi Neal, good video, it should answer a lot of questions that people have. I have a L47 TLB which has the DPF percentage screen that I always have on display. It's nice to know when a regen is nearing. I usually run about 2000 rpm's, and burn about every 30 hours. At lower rpm the percentage increases quickly. I've also noticed if I run it at higher rpm and work it hard enough the percentage will actually decrease. Enjoy the videos, keep up the good work.
New to the DPF world... Brand new L4802.. I thought low RPM would save engine wear and tear... been moving some logs around, pretty much under 1000 RPM... DPF came on at 16 hours... So, what is a good operating RPM when not using the PTO? I don't want to be to low due to DPF and not to high to run it in the ground...
Please advise!

Sorry about the errored reply. I run mine around 1800 rpm doing most jobs. Don't worry about wearing the engine out, with proper maintenance it will last a lifetime.
@@jc-botaman1077 thank you... I ran it at 2k today after the regen
I dont know about tractors but trucks the doc and dpf work together. The doc is first an injector injects fuel into exhaust that reacts with the doc to raise the temps to cook the soot out off of dpf
Good vid all the time
hmmmm , so there is a carbon cost to build this regen system, mine the metals-shape them-make filters-build into tractor-fuel spent in burn off etc. and you will need to buy a new one which leads to carbon cost of you driving to dealer and it being delivered to you. Meanwhile the fire dept. in Youngstown Pa. does not extinguish abandoned home fires which each generate more carbon than all of you and your friends tractors will generate in your lifetime!!!!! Thank you smart government thinktanks
Garbage no tractor should have.
Helped me out with a tym!!! Thanks!
I find this funny. I was working with a friend of mine who has a new Kubota he had to stop every 20 minutes or so while I ran my old Ford kept going all day. we were both running at almost full throttle heavy loads he's taken her back to fix it at least 3 times. I think I will keep my old Ford. It's not up to date and could use a rebuild, but she still runs. And I can rebuild her myself. I just need the time.
100% agree with @chuckquinn8026, you have a way of explaining the subject that common folk understand COMPLETELY without the drama and overacting the majority of you tube videos do!
So cool learning about tractors from Mac from Its Always Sunny
Another reason to buy a L2501 (no DPF)
You're like the Doug DeMuro of tractors. I mean this as a compliment, I love Doug.
I love Doug too... kinda my inspiration.
Yeah Doug is awesome
@@MessicksEquip Neal , your speaking voice is WAY more pleasant than Doug's lol. But both y'all are very informative!
$300-500 just to clean a filter? Damn.
That is ridiculous.
Highway robbery! They will do anything and everything to squeeze the last dime out of you.
Oh nice, a laptop computer and software required to fix your tractor. How much is that software? I hope it's less than $100.
DPF on a tractor thats going to see a couple thousand hours is ludicrous. EPA run a foul.
The more hours the machine is used the more sense I makes for the machine to be clean.
I can’t believe they put DPF on a tractor. What a ripoff .
My diesel truck always seem to start a regen when pulling up in my drive way. Most of the time I did not get a regen message I would see the mileage drop from 16 to 8 MPG. It would be nice to read the DPF pressure and start a regen at a more convenient time
You can read dpf loading with an obd2 reader on some cars
When did DOC and DPF first show up on S.S. sold tractors? Am I correct in believing that they are a Great Big N?A on an '05 NH TC33DA? I think that my money would be better spent on a total rebuild at 3000 hours than on a replacement. With 2500 hard hours and minimal maintenance she is getting kind of tired - especially the hydraulic pump. sdh in the Tobacco Valley of CT (GrunderLand)
My L3560 has done 3 regens at around 23, 24 hours between each one. Normally run it 1500 to 2000 rpms unless working it where it needs more. Should I run higher rpm all the time?
Is the exhaust on the L3301 (with DPF) "cleaner" for the operator to breath then the L2501 (without the DPF) or is it only an environmental thing? When working with tractors, your going to be breathing a lot of that exhaust. Thanks!
Most people wouldn't think about that, but you are correct. You don't notice the exhaust smell that you would on older tractors.
I did construction and for our heat in the winter and heat our tar we ran our trucks and the trucks had the dpf and the i would get sick but our one trk had been deleted and i could be standing right next to ot just like my old gm 6.5 or now my 7.3 ps and not be bothered by it
I'd be interested in learning the years and model's of kubota tractors that these emissions devices effect.
Came out in about 2011 give it take, anything prior to that just got 20% tacked into it's resale.
300-500 dollars to get the DPF cleaned out...NOT. Dad took his Kubota to the dealership in West Memphis(not mentioning names) to get the DPF cleaned out....$2000 bill. That’s all that was done. To say he was PO’d would be an understatement.
Sounds like they put a new canister on, instead of sending the element to be cleaned.
Not sure on kubota but otr trucks you can wash out your own dpf, need new gaskets etc but you still need the oem software to reset the cleaned parameter or the code still cannot be cleared. Ahh, isn't the epa great. Said no same man evah!
Mahindra doesn’t have DPF, Massey is coming out with tractors that don’t have DPF as well. I like kubota but I will buy a low hour used machine to avoid the extra potential for issues. Great video Neil.
That's the DOC system I talked about. It has it's own intricacies. 🚜 Kubota also makes DOC only engines, they just don't seem to think they are appropriate for tractor applications.
Try to repair that tractor without the laptop. It's impossible. This is the reason for the right to repair movement.
On a regular regwnnis the light supposed to keep flashing?
Does the new BX23s that took over the BX25D have a DPF and use DEF fluid does anyone know?
Stupid emission standards!
Hey Neil, this is not related to this video, but would you be able to do a side by side comparison with the Kubota BX23S to the New Holland workmaster 25s? Thought it might make a good video, both tractors look nice. Thank you.
I can't. It would create a political Firestorm for me. I will have videos on the New Holland coming, just not side by side.
Lol, I suppose, never thought of that. Thanks Neil!
Neil, thanks for an honest answer. That is why I like your videos and the information you present. Thanks again and keep up the good work
🙂
The true question is, can it simply be deleted??
yes. anything is possible. enough frustration products will be made
Did the rgen issues with the b3350 get sorted out because I am thinking about buying one used. What should I look for. And is all service bulletin tracked by the serial number of the tractor. Thank neil
Mostly... Can't say 100%.. but it can be done. If I have any concern it would be in the far Northern climates. In the South I wouldn't hesitate.
Mi Heating Guy I am using a 2014 B3350 with all the updates on it. Last summer it ran great, and never had an issue. Once our fuel supplier switched to winter diesel it would fail about 15 minutes in, then once it cooled it would complete a regen and be fine until the next regen. Now that I’m back on summer fuel, it is doing fine again. That said, my dealer informed me that it could be due to a possible timing issue of the fuel pump, and they are working with Kubota to solve the problem. I would still buy the tractor knowing what I know now, and I am confident my issues will be solved soon.
Messick Farm Equipment I'm in southern michigan and it gets pretty cold do you think that I would have issues
It depends on your dealer. Your in a problematic area.
@@MessicksEquip Its not the area thats problematic, its the emissions system.. All our non emission Kubota's run great in the cold :)
Thank you! How do some other brands sell their tractors without emissions?
They don't. They all have to meet the requirements.
Mahindra's marketing is maybe one notch above politics. That's a DOC-only engine, also used by a half-dozen other companies. Same thing as a DPF but rather than running a cycle every 20-40 hours its always running hot and burning continuously. There are pro's and con's to any of these engine systems. The con's on this system is more use of EGR (exhaust recirculation), overall higher engine temp's, and warm up \ cool down periods before and after you operate. I've heard other Mahindra dealers refer to this as a "no emissions" engine, that's simply not truthful .
Thank you for the replies! I bleed Orange so it doesn’t really matter to me.👍
Better to try to get the tractor working when during the Regen process. Have this on the firetruck I drive. Run enough on the highway and don't have to go through the cycle at the station.
Fire trucks and ambulances have different "shut down rules" than typical on road diesels, and they should. The regen software is similar. Years ago the soot went into the atmosphere and noone made money on the exhaust. Today the exhaust is filtered, collected and then washed into our water system, an entire industry makes money and the epa collects more money if u don't comply. The same pollution is there just more expensive.
Have you seen longer longevity in the newer emmision tractors compared to the older ones?
It'll be decades before anybody really knows. The stuff is far from new at this point, but the last couple of generations of equipment just don't have the age to them yet.
Messick Farm Equipment if it fallows the truck market, no. Not even close.
Shredxcam22 He mentions in another video tractors a bit different than trucks because tractors are sitting at higher RPMs more than trucks.
Is it correct that tractors in Europe have had these emissions requirements for years? If so that would be a good source for information.
What is an appropriate rpm to run an L3901? I have 67 hours and have had 3 regens(16, 32 & 59 hrs). The third regen was done during snowblowing season where pto rpm was used all the time. I don't want to run 2300 for normal use,though.
run whatever is appropriate for your task, but I'd stay about 1/3 most of the time.
wright or wrong I prefer my 92 kubota ....runs like a top
My L6060 is at 91% full (22.4 hrs on the tractor) and has not asked for a regen, my dealer said to let it go to 100% and see what happens. That sounds pretty risky to me ???
One comment you need to say on DPF is use of engine oil. My Kubota Dealer drove 60min out to do a on farm first service with wrong type of oil(kubota CH-4 Oil). He did not know my tractor had a DPF until i point it out. If I did not pointed out and call back to based. I would have had Kubota CH-4 oil in the Engine. What would happen i did not put in correct oil to engine?
Lucky he had some Isuzu DPD Approved oil. but not still not CJ-4 oil. But they say they use that oil in DPF equip Kubota..
Likely nothing bad. Owning a diesel car shop I've seen many clients running well over 100K on CJ4 oils with not DPF issues. Modern oils are really low in the "bad" stuff that kills the DPF. The CJ4 is even lower still.
Do you have to have that or can you take that off
Do the BX series tractors have any of these emissions devices on them, or are they under the Horsepower ratings?
they are under 26Hp, so there is no need for a DPF.
@@MessicksEquipThank goodness for that! I really feel we are generally starting to go backwards now in the world of machinery.
Does Kubota allow us (general users) to buy that software and cables? (Right to repair)
No I don't think. We pay several thousand a year for the licenses and adapters. It's really expensive stuff. Other than making neat charts, I've never seen anything in there of value to an individual owner. I do follow right to repair and consider myself a supporter of it.
@@MessicksEquip The main reason for soot is Ethier to much fuel or the engine is not up to working temperature / Excess idling to keep the soot burn off
If it was me I would have an ECM setup that would read the EGT when idling and throttle the engine up to working temperature to burn the soot off and throttle back down according to the EGT the electric cooling fans work similarly to that but I'm not and electrical or a software engineer
I was taught never let a diesel set idling for extended periods and to let the engine idle 5 minutes if its turbo charged after being worked hard to prevent wet stacking and coking in the turbocharger oil lines!
the manufacturer spends millions of dollars developing the system, sensors, hardware to get all this epa mandated crap to run. they are liable if it works incorrectly ( ask Volkswagen) so if you have not attended factory training and have factory authorization- serious doubts they will sell you any software. it's a catch 22 situation if there ever was. I don't see apple selling software to fix their devices and they don't have the epa leaning over their shoulder. not saying some tiny company cant develop their own to sell- that's another story.
Apple doesn't want anyone working on their electronics, but go get a proper computer. You can download the service manuals for all thinkpads for free, which shows ever screw, part number, option, and all the correct specs. They learned to be successful with giving consumers the information to repair everything, so why can't other companies?
@@firstname6208 They should be made to have the software available for people to make repairs, They arent liable for someone who isn't employed by Kubota using software..
Just like Apple isn't Liable if i activate a bomb with my iPhone
Operating at high rpm with extra fuel for twenty minutes! Sounds like a Deal.
No that's okay, I'll buy the older models that don't have this bull in it.
I have a M6060. My owners manual says that when the Regen symbol comes on you should place it in Park and the computer will automatically raise the engine speed. This never happens. I have to raise the throttle myself and eventually the light will go out.
That's a parked regen, you generally won't do that. Rev it and keep working.
Hey Neil,
I have a M135GX. I done many regen so far on the tractors. Is there an option with out a computer to start a regen early? Ie at 90%. My first regen request was like 1min before shutdown for the night at 11pm, I had to inhibit it and do a regen next time(a month later) i started up. But if in knew i have hour before shutdown i can do a early regen and get the filter clean out.
Also can you do a video on Diesel performance chips.
Or how to save fuel. My M135GX drinks a tanker load more of diesel vs the M125X it replaced under the same condition. I feel like my local fuel station is becoming my best friend and my plastic is getting paper thin.
you can do a parked regen whenever you want.
How about early regeneration on the go?
Where's the environmental benefit if these things use more diesel... Sounds like a con to me.
I’m sorry but the fuel used to ReGen doesn’t seem Eco-friendly. Has anyone independently done analysis to see what is the real gain of the DPF ? EPA emissions trash causes problems which seem counter productive and further environmental impacts.
check the channel. I did some specific measuring of the fuel use during regen and its almost not detectable.
Hey Neil does any of the tractors use DEF fluid?
Everything over 75hp
Your guy said it was two different systems.
Can I force a regen if I am out working the tractor hard?
if you are out working the tractor hard- when requirements are met- it will (should) do it automatically. if you know it is in the middle of a regen and you have finished your work- allow the regen to complete before shutting down or the regen will not give credit and you will not return to zone zero which means you still need the regen.
And running the tractor at redline for 25-30 minutes when it doesn't have to doesn't consume more fuel?? What??? And on top of that even more fuel is being dumped in on the exhaust stroke.
Multiply this by MILLIONS of tier 4 final tractors and trucks....that "small amount of fuel" adds up quickly....in the end, oil companies pocket the extra cash and the environment still suffers.
And let's not forget dealers who make thousands in profits a year fixing this unreliable garbage and even more replacing blown up engines and bent connecting rods from leaking EGR coolers.
Absolute theft.
If the machine is for private/personal use only, is there a means of deleting these systems?
never seen one.
And, private/personal doesn't make it legal to remove.
Jason Daniels I can see the benefit of emissions equipment on professional/contractor equipment. They run multiple pieces of machinery for for thousands of hours per year and that much pollution can add up. These professionals can absorb the added cost as overhead for the maintenance and downtime emissions equipment inevitably causes. Landowners and hobby farmers don't need the headaches, complexities or costs and have far less environmental impact.

No, that's not correct. Under 25hp a dpf is not needed to meet the requirements. The engine is still tier 4, but the standard is not a strict.
In trucks DOC burns the stuff then DPF filters it and SCR w/ DEF gets rid of NOX (over simplified) I work in the med and heavy duty truck industry. DOC, DPF, SCR, and DEF system all equals money and more down time. Fuel economy went down for trucks. Exhaust is a lot cleaner and smells better and its the law. DONT skip your regens!!!
