Hydrostatic Stump Grinder with Honda GX630 Power
A self-propelled stump grinder for crews, rental yards, and landowners who need hydrostatic jobsite movement, electric start, and commercial cutting capacity.
The Dosko 691SP-20HE self-propelled stump grinder pairs a Honda GX630 gasoline engine with hydrostatic drive so operators can move the machine around the jobsite with less pushing and positioning effort than a standard walk-behind grinder.
Its 14 in. diameter cutter wheel, direct belt drive, and Greenteeth 700 Series tooth system are built for aggressive stump and root removal across residential, farm, rental, and light commercial work.
Listed cutting capacity is 24 in. above grade and 18 in. below grade, with a 500 lb dry weight and all-terrain tires that help keep the unit tracking during transport and grinding.
Battery note: electric-start units are not sold with batteries due to shipping restrictions and battery safety requirements.
Dosko Self-Propelled Stump Grinder Key Features
Honda GX630 Electric-Start Engine
The 688cc Honda GX630 gasoline engine gives this stump grinder dependable power for repeat use, with electric start for easier startup.
Self-Propelled Hydrostatic Drive
The hydrostatic drive system helps operators navigate the machine around the jobsite and during transport without relying only on manual pushing.
Greenteeth 700 Series Cutting System
Eight Greenteeth 700 Series teeth use a concave cutting edge and can be rotated in three 120-degree increments for a fresh edge in minutes.
High Above- and Below-Grade Cutting Capacity
The grinder is rated for 24 in. above grade and 18 in. below grade, helping remove visible stump mass and below-grade root material.
Operator-Focused Handlebar Adjustment
A 5-position adjustable handlebar helps operators find a more comfortable working position while grinding.
Side-Discharge Frame and All-Terrain Tires
The side-discharge frame helps move chips away from the machine, while 16 in. x 6.50-8 in. tires support jobsite movement.
