Rotory Stump Cutter

This is really amazing. Never seen anything like it.

I'm amazed at how it's geared down like it is, but I realize it needs massive amounts of torque. Check out the way it moves the tractor! It's pretty clever if you ask me.

In the second video, look at the way it twists the frame of the tractor from about 1:10 on to the end. Looks pretty tough on the machine.

On the links in previous posts, it works if you click on "Youtube" but not if you click on "John Deere." It looks like one link but it is two.

It's a funny link for some reason. Click on the part that says 'youtube', not the 'john deere' part.


edit: sorry to repeat. bcp beat me to the post.

Yeah, I've seen videos of them before...Wonder if they make one to fit a BX???

They tried it, but the BX spins around and the stump stays still.

Cool machine. But i wouldn't want one on my tractor. looks like a lot of stress on the tractor

Why do they have them rotating CCW?? Doesn't seem like it would make any difference to rotate either way, but both of those models are shown going CCW like there may be some advantage rotating that direction??

I bet they cost a chunk of pocket change though!

That a CAT2? Lot of power being geared down and transferred to ground there.

I saw those videos a while back. Theres several models. Some are like a big core drill. Some mounted on mini Excavators.

Theres a video of one working in a tree farm. Could see it in that use after the trees are cut.

Pretty sure they build a custom heavy duty subframe from front to back to run the auger. Spreads the load around to the whole machine. I also think that Bi-Directional PTO is required as well.

Seems like the debris is much larger than a regular stump grinder and would take longer to decompose. I am sure it has its place though.

Very impressed with the speed of operation. I removed a stump the size of the one in the first video with a bobcat mounted grinder and it took about an hour.
