It’s not a sexy video, but this thing was grinding our 20”-diameter stumps, down 6”-12” underground, in about 7 minutes. I also ground out 5’-diameter stumps. I did about 450 stumps on my land after a logging operation. It works.
I see all of that torque putting quite a bit of twisting force on the arms of the machine. Do you believe this could result in damage to the machine over time?
David M I suppose damage is a long-term possibility, but on a machine the size of this T770 I wouldn't think so. This machine is designed to lift almost 10,000 lbs, so it's pins and loader arms are pretty stout.
Arnold's Design It was a lot of stumps. Took me 7 full days. It saved me a lot of aggravation when I ran a dozer over this 15 acres to smooth the terrain out and I didn't have to dig out the stumps, make big stump holes, or have to dispose of 400+ stumps and root balls.
If you would ever do start up classes I'd pay money for that. Talking about money and different techniques to do things as well as machinery and attachments.
mark197867 Yea, I've been posting more videos geared on the business owner and operator side of things. I hear input from others in this business, which I appreciate, and I like hearing what topics people are interested in seeing or hearing details about. If I have some experienced based info in that area then I'll put a video up.
Typically I dig my stumps with a cat 323F excavator. I do a lot of land clearing from simple tree lines to 100 acre patches to return back to farming. From your experience would this be faster and more cost effective than what I am doing now? I would be running the stumper on a bobcat t870.
Jared S This Stumpex is effective at cutting the stump and tap root out, and 4:30 minutes is pretty fast. I demoed this on my farm, and I was averaging 60-70 stumps per day. I would sharpen up the cutter at the end of each day. I cut out 400+ stumps in 7 days that were this size and larger. I used a Bobcat T770 here. Run at full RPM, and I burn about 4.8 GPH. This Stumpex cost $19,900, new, in 2017. So that'll help compare costs to your excavator production costs for pulling stumps. But one big advantage is that there is no mess with this method. No stump to dispose of, and no hole and loss of soil. This ground is ready to mow over or disc for planting.
what sort of cutting surface (material) does this use? Is it a steel cutter? Seems like hitting a rock would be much less catastrophic than with a stump grinder.
sir eliot Yes, the cutting edge is some grade of hardened steel. The Fecon sales information says it was specifically designed to be a low-speed, high-torque stump grinder. The slow movement of the blade will push rocks and debris out of the way without the high-impact damage a faster cutter can sustain. When the blade comes against something immovable, the cutter will just stop, and you can reverse the blade and reposition it. Another feature of the design is for safety. It does not throw material at all.
SanFranciscoBay You're right about that. All you need to do after 5-minutes of grinding a large stump, is to push the wood chips back into the hole, cover it with soil and throw some grass seed on it. Good to go.
@@clevingerforestservicesllc1164 Well, don't get me wrong, I love the Stumpex, but it's not quite as simple as that. Over time the wood down in the hole will rot and a deep depression will appear in the ground. Further work is then needed. But that will be the landowner's problem.
Terry W I really just let the weight of the attachment push it down, and let the threaded cone pull itself into to stump. I didn't want to bend anything by putting the weight of a 10,000 lb machine on it.
Terry W Putting it in float would work fine, I was just being careful with it. There were times when the cutting edges were getting dull that I did put the weight of the machine down on it. This Stumpex is built stout.
T Hill This is the only speed it turns out. They say it was designed this way for safety, since it doesn't throw debris, and if it hits something immovable that it won't violently break anything and it just stops. The giant gear box is a massive gear-reduction gear box that turns the high-flow hydraulic pressure, into a high-torgue, low-speed cutting action.
Nathan Stow I rented this Fecon Stumpex from a local equipment rental store. I went on the Fecon website, found the closest Fecon dealer near me, called them and asked where I could rent a Stumpex from that was close to my location, and they gave me a list of equipment rental stores near me that they supply. I can't remember exactly what I paid to rent it, but it was in the neighborhood of $1300 for a 7-day rental.
Boskaking123 Gaming The Stumpex attachment in this video cost $19,900 new in 2016. It's manufactured by a company called Fecon. They can give you the current retail price. The cutter blade of this attachment has a total useful life of about 1000 stumps, the company says. It can be sharpened using an angle grinder. When the blade is worn out, it can be unbolted from the gear housing and replaced with a new cutter blade. A new replacement blade cost about $9000 in 2016.
@@clevingerforestservicesllc1164 A total useful life of 1000 stumps? I thought I read that Fecon says sharpen after 1000 stumps? Implying that the total useful life of the blades is longer than 1000 stumps. $9000 is a lot to pay after every 1000 stumps.
No, I did not end up buying it. This Stumpex works very effectively on stumps, but I just didn’t have enough customers asking for large stump removal services to justify buying one for my business.
I don't do stump grinding as part of my business, so I can't answer that. I was using this Stumpex on my farm to grind out 430 stumps. I would have bought one and added this to my services, but I don't get enough calls for stump grinding to justify the cost of this attachment.
mark197867 I'd say this Stumpex was a very effective and safe device for clearing stumps. I ground out 400+ stumps with this in 7 straight days, so it was a little mind numbing. Lol.
Plus, we learn at the end this was cedar. Very hard wood. David, has your experience been that the speed on cedar is slower than most other trees of same size? (You may want to add to the title or description that it's a demo on cedar. Will be all the more compelling to some, whose land is "blessed" with its stumps.)
Charlie Arehart Yes these cedar are a pretty unique wood. Last forever and smell good. When I use this Stumpex cutter on the cedar stumps, the wood broke up in what I would describe as little cubes as opposed to shavings. Although this was a boring process, the cedar was interesting to cut because it just popped off like popcorn popping. It took the same amount of time to grind as the other stumps of the same size, which were mostly different oak species. Honey locusts was the hardest to grind.
WHEN I WATCH IT TURN, IT SEEMS LIKE IT'S SLOW. I DIDN'T PUT A STOP WATCH ON IT. YOU ARE CORRECT...4+ MIN FOR A LARGE STUMP SEEMS PRETTY GOOD. I'VE GET LOTS OF STUFF TO GO WITH MY S250 AND S650. THEY ALL SEEN TO BE REVVED EXCEPT FOR MY AUGER HEAD. SORRY IF I OFFENED YOU, DIDN'T MEAN TO. SOMETIMES IGNORANCE IS BLISS YOU KNOW. LOL
bear9923 No worries. Didn't want to sound upset over a comment. It's just better when comments have information that can help others who are having problems getting rid of stumps, and would like to see or hear about options that are effective. This Stumpex is mind numbingly slow moving, Believe me I know- I cut out 400+ stumps with it, but it is effective, and I think it does as good a job as a typical high-speed disc stump grinder. I do appreciate you watching and commenting, too.
I do appreciate your time very much. I will keep watching your videos. Be safe and thanks.

Why not a large stump grinder?

Excellent! Knowing that will surely make me enjoy running the Vermeer even more (sic)
Would an 8400 pound, 75-horse Kubota SSV75 wheel loader be enough to operate this thing?
I rented this Stumpex, so I don't know all of the specs needed to run it on different machines. I would guess that 75HP is enough to run it.
Shaving a stump while it's in the ground seems the most efficient way to get rid of stumps.

Also, the soil you put in the hole will compact no matter how hard you tamp it in.
I have the same T770. Do you run the stump ex on high flow? Or standard flow?
This Stumpex was designed to run on high-flow.
How much down force are you using? I didn't see the toes of your tracks lift, so you must be keeping it lite.
Terry W I really just let the weight of the attachment push it down, and let the threaded cone pull itself into to stump. I didn't want to bend anything by putting the weight of a 10,000 lb machine on it.
I wondered if you just hit the float button to let the arms and the attachment rest on the stump. Do you think that's too much down force?
Terry W Putting it in float would work fine, I was just being careful with it. There were times when the cutting edges were getting dull that I did put the weight of the machine down on it. This Stumpex is built stout.
Can you run this attachment at a higher speed or is this as fast as you can go with this attachment
