20 HP Walk-Behind Stump Grinder for Land Clearing
A commercial-duty stump grinder with Honda GX630 electric-start power, 20 in. above-grade cutting capacity, and Greenteeth 700 Series teeth.
The Dosko 620-20HE walk-behind stump grinder is built for landowners, rental yards, tree crews, and property-service operators who need serious cutting power without stepping up to a self-propelled machine. Its Honda GX630 electric-start engine and direct belt drive help turn cleanup jobs into controlled, repeatable stump removal.
A 14 in. diameter cutter wheel with eight Greenteeth 700 Series teeth cuts up to 20 in. above grade and 10 in. below grade. The side-discharge frame keeps grindings moving away from the operator while the adjustable handlebar helps dial in a comfortable working position.
This electric-start model requires a customer-supplied 12-volt Group U1 lawn tractor battery; due to shipping restrictions, the unit does not include a battery.
