I'm looking for a particular type of pto mounted stump grinder that has a minimum 12" wide cutting wheel. I have 2-3,000 apple tree stumps to take out and I'd like to grind them in one pass rather than use the type of grinder that sweeps back and forth.Does this sound familiar to anyone? I think I once saw one of these on E-bay.(I've got 75HP at the pto.)

Yes, the one you are thinking of is called a "Stumpster", it is made in Texas, and they have a website with all the info you need and more. It is a pto driven wheel about 24" in diameter mounted on a slide mechanism, the wheel is 90 deg. to the tractor and slides front to back. If you start at the end of a row and drive along stradling the stumps you can move down the row easily. I must mention however, this is NOT the fastest way to deal with them and you will need to go fairly deep below ground level to prevent suckering. Best of luck. ....

Thanks Murf. I've heard the same thing from other people regarding suckering. Sounds like we better just pull the stumps (unless you have any ideas we havn't thought of). Thanks again for the information. ....

Depending on how big the stumps are look into a Brush Brute, it will take out up to about a 4" stump depnding on soil conditions, etc. Otherwise get a BIG backhoe, or large dozer with root rake, the cost will be lower than any other method. Best of luck. ....

Basically it is a specially designed, toothed implement which goes on a loader instead of the bucket. The teeth are setup in such a way as to grip the trunk of a tree caught between them, in fact the harder you pull up the tighter the grip, allowing you to tear small trees out by the roots, ie no suckering back. It will clear the width of the tool (5' & up depending on model & hp of loader) and allows you to stack the brush as fast as you can manuever. We use them on compacts, but have recently fitted on on the arm of a medium-sized tracked(16k lb) backhoe in place of the bucket, WHOOOEEE does it clear brush!! Best of luck. ....

Walter - I'd suggest that you locate and talk to someone who knows a little bit about stump grinders (someone that actually operates one) and the type of end result that you want. When you get away from the conventional wheel with teeth in pockets and the up/down motion with side-to-side sweep you may be in for an adventure you didn't expect. Also, don't listen to advice that tells you these machines are slow. Try a 44hp or larger machine towed behind a farm tractor. One person drives the tractor and one operates the grinder. You will be AMAZED at how efficient that operation is. Just go 12" or so down and later you can easily blade the debris back into the hole. No fill dirt, no backhoe, no ruts - just a good, clean job. Good luck with your project. (Try to make a deal with a local "tree man" at a unit price per stump. I've worked for people at a unit price and can make good money that way.) ....

Walter, don't get me wrong, I know about the Stumpster because we have one, it is 3 years old and works VERY well. However, there is a BIG difference in grinding a stump and removing a stump. Yes removal does sometimes cause a small hole, however, IMHO, the difference in speed (read $$$$$) is more than worth it in the end. We run the Stumpster with a 90hp tractor, so power is not the problem (in fact the unit runs exactly the same on a 40hp unit). The difference looks like this though (based on MUCH experience with both methods) a typical Hardwood stump of 6"-8" diameter, 6" above grade, takes roughly 5 minutes to grind to a depth of 12", including moving tractor and setup time, that same stump takes about 1 minute with our backhoe, including dropping it into a dump trailer that follows along. While this does not sound like a big difference at first, do the math, a savings of 4 minutes, times 3,000 stumps is 12,000 minutes, or 200 hours, this is a savings of ten 40 hr. work weeks (for two operators and two machines). In simpler terms it would cost me five times as much to do it with a stump grinder, not really a tough decision..... Best of luck. ....
