Left hand joystick controls all tractor motion. Right hand joystick controls all blade movements. Mecanical Angle Dozer: 2. 6 m3 3. 4 yd3 Gull-wing engine side covers for easy and safer servicing. tilt dozer, Mechanical angle dozer combined the highest power in its class with outstanding productivity. High capacity Straight Wet, multiple-disc brakes eliminates brake-band adjustments for maintenance-free operation. Bolt-on segmented sprocket teeth for easy in-the-field replacement Komatsu torqflow transmission offers single lever control of speed (3 forward and 3 reverse) and directional changes. Forward mounted pivot shafts isolate final drives from blade loads. Modular power train for increased serviceability and durability. Photo may include optional equipment. 2 3 D68ESS-12 C R AW L E R D O Z E R CRAWLER DOZER D68ESS OPERATOR'S COMPARTMENT All steering, direction, and speed changes are made by a left-hand single joystick control. If the operator wants to move the machine forward and to the left, he simply moves the joystick forward and to the left. [. . . ] CLSS for D68ESS-12 Oil pressure check ports Oil pressure check ports for the power train are centralized on the right hand side of the operator Gull-wing engine side covers Coolant reservoir Cylinder Cylinder A radiator coolant reservoir makes it easier to check the coolant level and eliminates frequent refilling. A gas-spring cylinder opens the gull-wing engine side covers widely, allowing the engine and auxiliary components to be easily checked.
