Toro 23208 19" STX-26 Stump Grinder, some dedicated stump grinders are over-complicated. Not the Toro STX. Its patented Toro® Dingo® TX-style control system has two simple levers that are simple to learn, master and use. Combine these easy-to-use controls with tracks and transport speeds exceeding 4 mph, and you get maximum productivity. 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. The tracks travel easily over muddy areas, with the low center of gravity adds side hill stability for access to any job, in any condition. In addition, the hydraulically driven head means no chance of expensive belts breaking or slipping, and no adjusting tension - guaranteeing optimal performs time after time.
