Powered by a 325-horsepower Detroit Diesel 60-series engine with DDEC III electronic fuel injection, the 4800 is an efficient and powerful machine. Equipped with a heavy-duty boom and stick that delivers a maximum reach of 50' and a below-grade reach of 31', this hoe will lift 52,600 lbs. on a 20' extension. The 4800 is mounted on a D8 undercarriage, giving it 36'' of clearance.

Tracks are 13'-6'' wide by 18'-6'' long. Tractive effort is 129,300 lbs. The unit has a tail swing of 12'-6''. Counterweight, which weighs in at 23,000 lbs., is self-removable and is mounted 6' above ground. Weight of the 4800 is 132,000 lbs.

The cab is designed in a forward sloping configuration for high visibility, and includes two Lexan floor windows. Upper windows are guarded with full window guards. For operator comfort, there is a fully adjustable seat, joystick controls and sound insulation to reduce noise levels.

Jeff Tanner, territory manager for Madill, says the 4800 has one of the best access systems in the business. The canopy house lifts up hydraulically to expose the upper body mechanical system, including radiator, engine, exhaust and hydraulics. "The entire unit has been engineered for forest industry use," Tanner says, "right from the ground up. The D8 undercarriage with its high clearance, the heavy-duty boom and stick with maximum extended and below-ground reach, the high-visibility cab, and the hydraulically raised canopy and roomy layout of the mechanical components - all make it an ideal machine for the job."
