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.
• OVERSIZED TIRES EASILY ROLL OVER ROUGH TERRAIN: The lugged high-flotation tires make for easy transport. 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.
• MINING-GRADE TEETH LAST 3X LONGER: The cutter head features 8, 3-sided Greenteeth® 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 with 9.2 HP (15.3 ft-lbs gross torque*) spins the cutting teeth at 2,800 rpm – taking 372 “bites” per second and powering through stumps up to 3 feet in diameter. Available with choice of manual- or electric starting.
• 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.
