Features

• SIMPLE OPERATION: Position the DR Stump Grinder over the stump, engage one of the wheel brakes to lock a single wheel in place before engaging the cutting head and pivoting over the stump from side to side, shaving off an inch or so of material with each pass. Reposition the machine as needed to continue removing material until the entire stump is reduced to a pile of wood chips.
• SELF-PROPELLED FOR EASY TRANSPORT: Our dual shaft transmission, with built in differential, lugged, high-flotation tires and DR’s lightweight design makes for smooth, easy, self-propelled transport between job sites. Large size tires (15" x 4.75") give the machine full support and help to keep the body of the machine elevated over wood chips during operation.
• 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 LAST 3X LONGER: The cutter head features 8, 3-sided Greenteethâ mining-grade tungsten carbide tipped steel teeth. 10 times harder than steel, tungsten carbide is often used for drilling through the toughest materials, including bedrock and each tooth can be rotated twice for added longevity.
• POWERFUL ENGINE: Our DR OHV engine (389cc) with electric start puts 11.7 HP (19.6 ft-lbs gross torque*) at your fingertips. Cutting teeth spin at 2,800 rpm – taking 372 “bites” per second and powering through the toughest hardwood stumps up to 3 feet in diameter.
• SIMPLE HAND CONTROLS: Control the wheel brakes and engine throttle right from the handlebars. Lock one wheel in place to easily pivot the machine back and forth as you grind away any stump. Unlock and reposition as needed, right from your working position.
