Operator Station: Comforts such as swivel seat, ergonomically located controls, and all-season climate controls help keep productivity up. Grapple: Keep constant pressure on the tongs with two hydraulic cylinders designed to adjust to each load. Winch: Single lever ease of operation. Legendary durability. Axles: Inboard planetary axles feature self-equalizing, self-adjusting wet-disc brakes to decrease wear to on-the-fl y differential locks. Engine: Do more on less fuel with the powerful John Deere 6.8-L engine featuring high torque rise, heavy-duty engine blocks, and proven durability and fuel effi ciency. Transmission: Put the most power to the axles with our direct-drive PowerShift transmission. Quick Daily Maintenance: Make daily maintenance a snap with quick-release fuel fi lters and separators, spin-on oil fi lters, and oil-drain shutoff for spill-free oil changes. Rear Assembly: Built forest-tough to withstand the heaviest buffering, the adjustable fairlead, heavy butt pan, see-through ram-guard screen, and strong fenders protect the tires, rear frame, winch, and operator.
