Dosko Swivel Stump Grinder | 13 HP Walk-Behind | Honda GX390

Built for tight access and serious cutting power, the Dosko 337 walk-behind stump grinder is engineered to reach places larger machines simply can’t. Its compact footprint easily fits through narrow gates, walkways, and backyard paths, making it ideal for residential and confined job sites—without sacrificing performance. Powered by a dependable 13 HP Honda GX390 engine, this grinder delivers the muscle needed to take on stubborn stumps with confidence.
Dosko’s new swivel action grinding head transforms stump removal into a smoother, more efficient process. Simply roll the grinder into position, engage the single-lever wheel lock, and let the swiveling head glide left and right across the stump for an effortless sweeping motion. The side-discharge design directs grindings away from both the operator and the machine, keeping the work area cleaner and safer.
Equipped with durable Greenteeth® cutting teeth, maintenance is quick and simple—each tooth can be rotated in three 120-degree positions to expose a fresh cutting edge in minutes, minimizing downtime and maximizing productivity. Tough, maneuverable, and built for repeated professional use, the Dosko 337 is the go-to stump grinder for contractors and property owners who demand power, control, and efficiency in tight spaces.
