Toro introduces a new line of walk-behind stump grinders, the SGR-6 and SGR-13, for grinding small stumps in tight-access areas. Both units are engineered to be well-balanced, easy-to-operate and simple to maintain for smooth cutting and reliable performance. The 12-tooth cutting wheel on the Toro SGR-6 offers a cutter depth of 6-in. below grade and a cutter height of 10.4-in above grade. The SGR-6 comes equipped with a Honda GX200 engine and a heavy-duty centrifugal clutch. Toro SGR-13’s 12-tooth cutting wheel boasts an 11-in. below-grade cutter depth and a 14-in. above-grade cutter height. The SGR-13 is manufactured with a Honda GX390 engine and a heavy-duty centrifugal clutch. The exclusive Quadrublade tooth design on Toro SGR handle bar stump grinders cuts like a router without "pulling" the machine into the stump. Both models are portable, designed with lift handles for easy loading and unloading. The Quadrublade design also allows for easy replacement of the cutting teeth within minutes, keeping downtime to a minimum.
