Features

• SIMPLE OPERATION: Position the DR Stump Grinder over a stump, lock one wheel in place with the wheel brake, engage the cutting head, and pivot easily from side to side, shaving off an inch or so with each pass. Reposition the machine and repeat until the entire stump is reduced to a pile of wood chips.
• SELF-PROPELLED: Our dual shaft transmission, with built in differential, makes for smooth, easy, self-propelled transport between job sites.
• PROTECTIVE SHROUD: While in transport mode, the shroud prevents the spinning teeth from running aground. Once you arrive at your destination and disengage the drive, it's easy to expose the teeth (no tools required).
• MINING-GRADE TEETH: The cutter head features 8 steel teeth that are tipped with mining-grade tungsten carbide a material 10 times harder than steel and which is used for drilling through bedrock. Spinning at 2800 rpm, these teeth take a remarkable 372 "bites" per second!
• ENGINE: Our DR OHV engine (389cc) with electric-starting provides 11.7 HP (19.6 ft-lbs gross torque*) — all the muscle you need to power through the toughtest hardwood stumps of any size.
• SIMPLE HAND CONTROLS: Control the wheel brakes and engine throttle right from the handle bars. Lock one wheel in place while you pivot the machine back and forth to grind away a stump. Unlock and reposition as needed, right from your working position.
