[. . . ] See page 8. Genuine Answers for Land and Environment Optimization SAA6D107E-1 turbocharged after-cooled diesel engine provides an output of 125 kW 168 HP with excellent productivity, and is EPA Tier 3 and EU Stage 3A emission certified. See page 6. Gull-wing engine side doors for easy servicing. High capacity Power angle tilt dozer, Semi-U Tilt dozer (for D61EX), combines the highest power in its class with outstanding productivity. Wet, multiple-disc brakes eliminate brake-disc adjustments for maintenance-free operation. See page 8. Hydrostatic Steering System (HSS) provides smooth, quick, and powerful control in various ground conditions. [. . . ] 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.

High-tensile-strength steel has been incorporated into the front and sides of the blade for increased durability. D61-15E0 WA380-6 WORKING ENVIRONMENT Operator comfort Operator comfort is essential for productive work. The D61EX/PX provides a quiet, comfortable environment where the operator can concentrate on the work at hand. Comfortable ride with new cab damper mounting D61EX/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. Undercarriage Engine The Komatsu SAA6D107E-1 engine delivers 125 kW 168 HP at 1850 rpm. The fuel-efficient Komatsu engine, together with the heavy machine weight, make the D61EX/PX superior crawler dozers in both ripping and dozing operations. The engine is EPA Tier 3 and EU Stage 3A emission regulations certified, and features direct fuel injection, turbocharger, air-to-air and aftercooler to maximize fuel efficiency. If the monitor detects 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. 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. 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. Easy/cleaning with hydraulic driven radiator cooling 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.
