PTO stumper I run a J/D 955, 35hp tractor with a Shaver Stumpbuster, absolutely love it! I too cringe at the thought of buying a self propelled machine now. I've done some stumps for the local snowmobile clubs up here in Maine, much easier to drive my 4 wheel drive tractor a mile up the trail, than to walk behind a self propelled for an hour. I've had no problems with it, just very expensive to replace teeth on it. I am having them sharpened, but will have to go with a new set next year.
