[. . . ] The joystick provides the same steering response on downhill slopes as on flat ground. Grading-- can be done efficiently without damaging the ground, because the inside track is not locked during turning. Facing front Outline of electronic control system Fuel control dial Travel control lever Preset travel speed function Preset travel speed selection function is provided as standard equipment. The preset switch enables the operator to select a combination of forward/reverse gear shifts, from 4 patterns; F1-R1, F1-R2, F2-R1 and F2-R2, by using UP/DOWN shift switch, and once the shift pattern is selected, operator can control the machine concentrating his attention on directional control only. Once F2-R2 pattern is selected, for example, 2nd gear is automatically selected when travel control joystick is moved into forward/reverse. This function reduces gear shifting frequency during machine operation and is especially helpful when used in combination with Auto-Downshift Function.

F2-R2 MODE ECMV ECMV ECMV ECMV Auto downshift function Transmission output shaft speed sensor Controller monitors engine speed, travel gear and travel speed. When load is applied and machine travel speed is reduced, the controller automatically downshifts to optimize gear speed to provide high fuel efficiency. This function provides comfortable operation and high productivity without manual downshifting. (This function can be deactivated with cancel switch. ) Actuated on heavy load or steep slope Engine Electronic controlled transmission 4 5 D85EX/PX-15R C R AW L E R D O Z E R CRAWLER DOZER D85-15 PRODUCTIVITY FEATURES Work equipment Large blade Capacities of 5. 2 m3 6. 8 yd3 (Straight tilt dozer for D85EX), 5. 9 m3 7. 7 yd3 (D85PX), 7. 0m3 9. 2 yd3 (Semi-U tilt dozer for D85EX) yield outstanding production. High-tensile-strength steel has been incorporated into the front and sides of the blade for increased durability. WORKING ENVIRONMENT Operator comfort Operator comfort is essential for productive work. The D85EX/PX provides a quiet, comfortable environment where the operator can concentrate on the work at hand. Comfortable ride with new cab damper mounting D85EX/PX's cab mount uses a new cab damper which provides excellent shock and vibration absorbtion capacity with its long stroke. Cab damper mounts soften shocks and vibration while traveling over adverse conditions, which conventional mounting system are unable to absorb. The cab damper spring isolates the cab from machine chassis, suppressing vibration and providing a quiet, comfortable operating environment. Rippers (EX) The multi-shank ripper features a long sprocket center-toripper point distance, making ripping operation easy and effective while maintaining high penetration force. The multi-shank ripper is a parallelogram type ideal for ripping in tough material. The ripping depth is adjustable in two stages. Engine The Komatsu SAA6D125E-5 engine delivers 197 kW 264 HP at 1900 rpm. The fuel-efficient Komatsu engine, together with the heavy machine weight, make the D85EX/PX superior crawler dozers in both ripping and dozing operations. The engine features direct fuel injection, turbocharger, and air-to-air aftercooler to maximize fuel efficiency. If the monitor finds abnormalities, corresponding warning lamp blinks and warning buzzer sounds. The monitor displays engine rpm and forward/reverse gear speed on the upper part of the monitor during operation. If abnormalities occur during operation, user code appears on display. When a critical user code is displayed, the caution lamp blinks and a warning buzzer sounds to prevent the development of serious problems. Engine Hull frame Track frame Reliable simple structure Simple hull structure main frame design increases durability and reduces stress concentration at critical areas. The track frame has a large cross section and utilizes pivot shaft mounting for greater reliability. Easy cleaning with hydraulic drive radiator fan The radiator core and the core on the front side of the oil cooler can be easily cleaned by running the hydraulic engine fan in reverse.
