John Deere 450H Specification Sheet

John deere crawler dozers specification sheet.

 
Type .......................................................................John Deere 4045T with altitude-compensating
Rated power @ 2,200 rpm.....................................80 SAE net hp (60 kW)
Cylinders, wet sleeve..............................................4
Displacement .........................................................276 cu. in. (4.52 L)
Fuel consumption, typical.......................................1.7 to 2.6 gal./hr. (6.4 to 9.8 L/h)
Maximum net torque ..............................................255 lb.-ft. (344 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
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)
Heavy-duty triple-reduction final drives attach directly to the mainframe and are isolated from track frame and dozer frame loads
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
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
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
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
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.
