What owners say
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.
Arrived quickly, well-packaged for shipping, and as promised. This is a quality, well-built machine!
The SG24 chewed through oak like it was nothing. Took my weekend project down to a couple hours. MechMaxx makes some serious equipment.
Mounted easily on my tractor. Grinds stumps fast and deep — highly efficient.
Easy to use, easy to haul, and the PTO shaft just runs. Best purchase I've made for my business this year.
Same quality as the big names at a better price — and with better support. Will buy again.
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.
Lined up perfectly with my compact tractor. Quiet operation and the finish is clean. Excellent value.
