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. Accordingly, the cleaning intervals of those cores can be increased. Maintenance free disc brakes Wet disc brakes require less maintenance. Gull-wing engine side covers The opening area is further enlarged when gull-wing engine side covers are opened, facilitating engine maintenance and filter replacement. Side covers have been changed to a thick one-piece structure with a bolt-on catch to improve durability. Electric priming pump Simply pressing the button enables bleeding air from the fuel circuit at the time of filter replacement, etc. Heavy-duty track link The track link life is greatly improved through increased bushing diameter and link height in addition to lubricated track. 8 9 D85EX/PX-15R C R AW L E R D O Z E R DIMENSIONS CRAWLER DOZER D85-15 SPECIFICATIONS ENGINE Model . 4-cycle, water-cooled, direct injection Aspiration .
