We’re Here When You Need Us
On a standard walk-behind grinder the operator swings the whole machine across the stump. On the Dosko 337S-13HC the head swivels instead. You wheel the machine up, drop the single-lever wheel lock, and sweep the cutter wheel left and right over the stump while the machine stays put. It is a smaller motion, it is repeatable, and at the end of a day of removals the operator is measurably less beaten up.
Underneath it is the same 337 chassis — narrow enough for gates and walkways, 300 pounds, one-person loading. A Honda GX390 drives a 14-inch cutter wheel through a direct belt drive, cutting 20 inches above grade and 16 inches below. A cyclone air cleaner deals with the dust, and an oil shutdown sensor protects the engine on slopes.
The side-discharge frame throws grindings away from both the machine and the operator, and Greenteeth 700 Series teeth come standard: rotate each tooth 120 degrees for a fresh edge, three edges per tooth before it needs replacing.
Key Features & Benefits
- Swivel grinding head – sweep the wheel across the stump instead of swinging the whole machine; easier on the operator, faster on the cut
- Single-lever wheel lock – plant the machine once and work the stump from there
- Fits through gates and walkways – same narrow 337 chassis, back-yard access without dismantling a fence
- Honda GX390 – 389cc commercial engine
- Greenteeth 700 Series teeth (8) – three indexable cutting edges per tooth
- Cyclone air cleaner – extra filtration for grinding dust
- Oil shutdown sensor – protects the engine on slopes and low oil
- Side discharge frame – keeps grindings off the machine and away from the operator
- 5-position handlebar – set the working height to the operator
