1.7 to 2.6 gal./hr. (6.4 to 9.8 L/h)
276 lb.-ft. (372 Nm) @ 1,200 rpm
Lubrication .............................................................pressure system with full-flow spin-on filter and oil-to-water cooler
Air cleaner..............................................................dual stage dry type with safety element, precleaner, and dash-mounted restriction indicator
Electrical system ....................................................12 volt with 65-amp alternator
Cooling fan.............................................................blower
Transmission
Dual-path, electronic-controlled, hydrostatic drive; load-sensing feature automatically adjusts speed and power to match changing load conditions; each individual track is powered by a variable-displacement piston pump and two-speed motor combination; decelerator controls speed from holding to 5.0 mph (8.0 km/h)
Travel speeds (infinitely variable)
Forward and reverse ........................................0 to 5.0 mph (0 to 8.0 km/h)
Final Drives
Heavy-duty triple-reduction final drives attach directly to the mainframe and are isolated from track frame and dozer frame loads
Steering
Single-lever steering, direction control, and counterrotation; full power turns and infinitely variable track speeds provide unlimited maneuverability and optimum control; hydrostatic steering eliminates steering clutches and brakes
Brakes
Hydrostatic (dynamic) braking stops the machine whenever the direction-control lever is moved to neutral, whenever the decelerator is depressed to the end of travel, or whenever the brake pedal is depressed
Automatic Park Brake
Exclusive safety feature engages wet, multiple-disc brakes automatically whenever the engine stops, whenever the operator applies the brake pedal, or whenever the neutral start lever lock is in the stop position; machine cannot be driven with brake applied, reducing wear out or need for adjustment
Hydraulic System
System...................................................................open center
Pressure, main relief ..............................................3,000 psi (20 685 kPa)
Pump .....................................................................gear
Flow.......................................................................15 gpm (56.8 L/min.) @ 2,200 rpm
Filter, return oil .......................................................10 micron
Control ...................................................................T-bar three function
Cylinders ................................................................heat-treated, chrome-plated, polished cylinder rods, hardened steel (replaceable bushings) pivot pins
Capacities (U.S.)
Fuel tank with lockable cap....................................47 gal. (178 L)
Cooling system with coolant recovery tank.............17 qt. (16 L)
Engine oil including spin-on filter ...........................15 qt. (14 L)

Final drive (each)....................................................7 qt. (6.6 L)
Hydraulic reservoir refill with filter change .............8.5 gal. (32.2 L)
All power train and hydraulic systems allow 45-degree maximum operation.
Undercarriage 550H LT 550H LGP
John Deere Dura-Trax™ features large deep-heat-treated components; pins and bushings are sealed for life; rollers and idlers are permanently sealed and lubricated; fulllength track frame covers reduce material buildup and ease cleaning
