A long-time track favorite for tree service companies, stump grinding professionals and land clearing contractors, the Model 2900 Track delivers big horsepower and grinding power in a package that retains a good deal of maneuverability. It rides on a turf-friendly rubber track undercarriage that can expand to 53 inches for stability, and retract to 35 inches to clear narrow backyard gates. A very wide side-to-side cutter swing with big horsepower options from either diesel or gasoline engines make the 2900T the best choice for grinding big stumps quickly and efficiently.
