I was very surprised how well this went through stumps — went through 5 pine stumps ranging from 16 to 28 in diameter in no time.

The SG24 chewed through oak like it was nothing. Took my weekend project down to a couple hours. MechMaxx makes some serious equipment.

Easy to use, easy to haul, and the PTO shaft just runs. Best purchase I've made for my business this year.

The stump grinder looks very well made and arrived in excellent condition. Will not be using till this coming spring but I don't expect any problems.

Big stump, no problem. Cleaned it up in one pass. Sturdy build and the carbide teeth bite hard.
