Product Description

The Dosko 337S-13HC takes the proven 13 HP Dosko 337 and adds the feature that changes how you grind: a swiveling head. Wheel the machine to the stump, lock the wheels with a single lever, and sweep the cutting head left and right across the stump without moving the machine at all. Grinding a stump has never been this easy on your back or your time.

A 13 HP Honda GX390 commercial engine spins the 14-inch cutter wheel through a heavy belt drive, taking stumps 20 inches above grade and 16 inches below. The Greenteeth 700 Series teeth rotate to a fresh edge in minutes, and the side discharge throws grindings away from the machine and the operator, so your work area stays clear.

The swivel action is where this machine earns its keep. Instead of muscling a 300-pound grinder back and forth to chew across a wide stump, you stand in one spot and glide the head over it. That means faster jobs, less fatigue, and a real edge if you grind stumps for hire or rent the machine out.

Pull start it, set the 5-position handlebar, and grind. The oil-shutdown sensor and cyclone air cleaner protect the Honda engine, and the single-lever wheel lock keeps the machine planted while you sweep.

Ideal For: Landscapers, tree crews, rental fleets, and property owners who want faster, lower-effort grinding from a swivel head that sweeps the stump without repositioning the machine.
