Dosko Stump Grinder | 13 HP Walk-Behind | Honda GX390 | Greenteeth 700 Series | Model 337-13HC

The Dosko 337-13HC is a professional 13 HP walk-behind stump grinder powered by the Honda GX390 — a bulletproof engine trusted on job sites across the country. This unit tackles stumps up to 20 inches above grade and 16 inches below, making it the right tool for landscapers, tree services, and rental operations that need reliable stump removal without the size and cost of a self-propelled machine.

Dosko's unique side discharge frame keeps grinding debris away from the operator, while the 5-position adjustable handlebar lets you work comfortably for hours. The direct belt drive system runs three-groove PowerBand belts with idler bearing tensioners for consistent cutter wheel speed, and the Greenteeth 700 Series teeth are engineered with a concave dish cutting edge that shears clean rather than shredding — and each tooth rotates in three 120-degree increments to expose a fresh edge without a full replacement.
