Toro 23214 14" W STX-38 Stump Grinder is built for outstanding durability in the toughest conditions. Fully hydraulic operation means no chance of expensive belts breaking or slipping and no tension adjustments. The Intelli-Sweep® feature automatically slows the sweep speed of the cutting head based on the load of the wheel, so heavy cutting loads won’t bog down the engine. And with easy-to-use TX-style controls and tracks for maneuverability and stability, the STX-38 is extremely operator-friendly. The STX-38's electronic fuel injection engine provides less maintenance, easier starting, and improved performance. Best of all, ground speeds of 4.5 mph allow you to spend more time grinding — and less time transporting the machine — for greater productivity.
