(optional) CRAWLER DOZER D85ESS HORSEPOWER Net: 149 kW 200 HP @ 1950 rpm OPERATING WEIGHT 20670 kg 45, 570 lb WALK-AROUND The Komatsu S6D125E-2 diesel engine provides an output of 149 kW 200 HP with excellent productivity. Left hand joystick controls all tractor motion. Right hand joystick controls all blade movements. Optional hexagonal, low noise cab with viscous damping mounts provides unsurpassed operator comfort and visibility. BLADE CAPACITY (SAE) Straight Tilt Dozer: 4. 4 m3 5. 8 yd3 Angle Dozer: 3. 4 m3 4. 4 yd3 Gull-wing engine side covers for easy and safer servicing. [. . . ] Track frames have a large-section construction for maximum rigidity. Even the box-section construction of the blade back beam is reinforced, all with durability in mind. Benefits of CLSS More precise and responsive operation due to the pressure compensation valve. Reduced fuel consumption by discharging only the required amount of oil from the pump. The work equipment moves smoothly for operations such as side-cutting even when priority is given to steering. CLSS for D85ESS-2A Low drive and long track undercarriage Komatsu's design is extraordinarily tough and offers excellent grading ability and stability. Hexagonal pressurized cab (optional) Air filters and a higher internal air pressure combine to prevent external dust from entering the cab. In addition, the cab's hexagonal design provides excellent front, side, and rear visibility. The viscous damper cab suspension softens shocks for operator comfort and extends component life. Cylinder Cylinder EASY MAINTENANCE Wet, multiple-disc brakes Eliminate brake-band Oil pressure check ports (optional) Oil pressure check ports for the power train are centralized on the right hand side of the operator platform for easy access. PPC Unload valve PPC Unload valve adjustments for maintenance-free operation. Tank Tank Gull-wing engine side covers (optional) Coolant reservoir A radiator coolant reservoir makes it easier to A gas-spring cylinder opens the gull-wing engine side covers widely, allowing the engine and auxiliary components to be easily checked. Electronic monitoring system (optional) An electronic monitoring system prevents minor problems from developing into major ones. All meters and gauges are controlled by a microcomputer, which provides a wide indication range for an easier, more precise reading. check the coolant level and eliminates frequent refilling. 4 5 D85ESS-2A C R AW L E R D O Z E R CRAWLER DOZER D85ESS SPECIFICATIONS ENGINE Model. 4-stroke cycle, water-cooled, direct injection Aspiration . 125 mm x 150 mm 4. 92" x 5. 91" Piston displacement.
