MechMaxx SG380 Kohler Stump Grinder
#3 in Walk-behindFull review
The SG380 for a buyer who values a name-brand engine and local service. Otherwise the Ducar version does the same work for less.

A low-cost way to get key start and a tow bar. Fine for a homeowner whose stumps stand tall rather than run deep.
