This is well worth the money. I had approximately 40 stumps to grind — took me just a few evenings after work to accomplish. I highly recommend.

Works good. For me it takes two people — one drives the tractor and the other lines me up.

Like the product, it works really well — just if you don’t have a spotter, definitely get the camera to save the neck pain!

I am very satisfied with the mechmax stump grinder. I used the pallet to make a cart by mounting a 2x8 and 2½in casters.

We hooked this up to our tractor and tried it out. We had several really hard walnut tree stumps. It took them out without any trouble at all. Worked great. I have 6 acres so we will be using this often.
