Good video explanation! I have a 455 and a 425 The difference is like night and day. I am going to sell the 425 soon lol. Even just engaging the mower deck is a totally different feeling but using the loader is what really makes you feel the difference in power
Since I own a 332 I never wanted to go back lots of people say get a 316/318 and I just don’t want to since I own the diesel I just enjoy the diesel and the power and how much money I save on fuel by running diesel
I’m running a different color then most of you and got on this channel with the great Onan content. I have repowered one Case 446 with a 2 cylinder Perkins and am in the process of converting my original due to Onan part costs and fuel savings. In the 6 months of running my “Deisel Demonstrator” I burn 1/4 the fuel of an Onan or 1/2 of my kohler, so I’d say your fuel saving estimate could be a bit light.... but I know that green paint makes fuel evaporate a lil faster... lol 🤣
I do focus on Deere stuff but I appreciate them all....I have a couple non-green ones. I do think you are correct on the fuel use for other comparisons. In my head I was mostly using the 445-455 and the X728-X748 comparison (at 100 hrs per year). As with any case the more you use it the greater the savings will be.
I am in a quandry and could use some immediate advice. I test drove both the x 738 and x 758 yesterday at a dealer and found the 758 to be more responsive ( faster) and the engine sound much like a mercedes sl 560 I previously owned. Smoother and quieter than the 738. My confusion is in the fuels ( gas vs diesel) in a cold northeast climate. Gelling in diesel problems along with no start situations vs gas starting in all kinds of weather. What are your thoughts on that?
Would it help if I mentioned we live in SD where we will see a week or more of below zero at a time and all my main users are diesels. My older X748 and 1445 front mount mower are routinely started at 0 or below in the winter. Key thing is making sure that you either treat the fuel or have winter diesel (most places around us switch to a treated diesel in October). I’ve had fuel gel on me once, I forgot to treat the diesel in my 4066R and I was moving snow at -15F.
@@mmrbeef Thank you kindly for your quick reply and advice. I live in NH where we also have -0 weather quite often and snow ranging from 4-18'. Getting proper diesel is the trick around here. I really did like that x758 over the x738 and the cost factor is not much considering everything. Thanks again.
The diesels are definitely more power and use less fuel that being said I’ve found my 445 to be plenty of power. I run the 54 inch deck no problem and I use the 47 inch 2 stage blower with zero power issues. I also have the John Deere 450 pto tiller that it handles great I always thought that for mowing the 455 was just to dang loud vs the 445 or 425 to justify the extra power During the MN winters I put up with I’d much rather deal with a gas in the cold. I’ve always spent the extra money and I buy premium gas and have had zero problems with it going bad sitting around for even 6 months at a time The less ethanol the better We have had multiple 455 445 and 425s over the years and have found the 445 to the the best overall for us. Love the videos keep them coming
I have a 400 that had the k532 gas engine. I would have to fill up mid session every time mowing 4 acres. Last year i pulled the engine and installed a kubota d662 16hp. diesel. I can mow 4 times before filling. It doesnt take long to make ip for $1600 increased purchase price. Also, the power is night and day. The diesel is far superior. If this isnt an apples to apples comparison then there is no such thing.
Enjoyed watching this video. Like most, I prefer the diesel to the gas. However, due to the tier 4 regulations, I'm seeing gas engines being used in many > 25 hp requirements where we would think diesel would be a better fit. 2 examples: Ventrac, and UTVs.
The one thing i think you missed as a pro for gas engine is typically they have more HP, example 318 or 322 versus a 332 . 318 and 322 have 18 HP vs. 332 diesel 16 HP . My magnum 18 in my 317 more HP than a 332.. and HP is what maintains speed . Torque propels you so actually if you hit a pile of snow while moving the higher HP will continue longer than a diesel,, however if you are stopped in front of a pile of snow and go to push it the diesel will fare better .. those examples are just physics not a knock on one or the other but apply to all engines electric diesel or gas..
A 15 hp diesel will outwork a 25 hp gas engine on 1/4 of the fuel and 10 times the longevity. Most small liquid cooled diesels will easily last 30k hours with basic routine maintanence. Air cooled gas is probably around 3k before rebuild. Thats not to say a gas engine isnt a better option for some as the speaker eludes to.
@@bus-fun-addict 30k hours? Thats a little far. As a mechanic, the most ive seen was 12,000 hours on a Kohler K Series GAS engine. Now i do firmly believe a diesel will last longer but im my multiple decades of working in the field, have i seen 30k hours.
as always, great explanation of the pros and cons of each

Thank you for this video! Really helped on deciding what my next garden tractor will be.
Nice video. I am 99% sure I’m ~20 miles west of you. Love the 4Runner videos and rocking a x748 too.
Nice comparison. I would say around 900 hours is about max life for a gas. How many hours would you expect a diesel? Looking at a X730 vs X750. Thanks

I just hate having to go fill up my 5 gallon can. The less I have to do that the better, that's a big reason for me for diesel.
Just traded in my 2015 x534 with 170hrs and got 5,000 for it . Got a 2020 x758 with snowblower can’t wait till it comes in.
Congrats on the new ride!
