Dosko Swivel Stump Grinder | 13 HP Walk-Behind | Honda GX390 | Swivel Grinding Head | Model 337S-13HC

The Dosko 337S-13HC Swivel Stump Grinder takes the proven 13 HP Honda GX390 platform and adds a game-changing swivel grinding head that makes stump removal significantly faster and less fatiguing. Instead of repositioning the entire machine to work across a stump, the operator locks the wheel with a single lever and sweeps the grinding head left and right with a natural swivel motion — covering the full stump width with far less effort.

The side discharge design keeps grindings away from the machine and the operator during the sweep, and Dosko's Greenteeth 700 Series teeth deliver the same clean, efficient cutting found across their professional stump grinder lineup. With a 14-inch cutter wheel, 1.375-inch bearings, and a five-position adjustable handlebar, the 337S-13HC is built for all-day commercial use — and the swivel action means you'll finish each job faster.
