MechMaxx SG380 Stump Grinder
#1 in Walk-behindFull review
The best equipped walk-behind for the money. It suits a homeowner with many stumps who wants to tow it and swing across each one.

4.1/5
The SG380 for a buyer who values a name-brand engine and local service. Otherwise the Ducar version does the same work for less.

#2 in Walk-behindFull review
A well-built Kohler grinder with key start and a long warranty, for frequent use. It costs a little less than the MechMaxx SG380 Kohler but does not swing across the stump.

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