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 large 75″ cutter swing and a Caterpillar 120 horsepower diesel engine make the 2900 an ideal choice for grinding big stumps quickly and efficiently.
