7 Transmission gearshifting is simplifiedwiththumb push adjustable new airsuspension seat andtravel control consoleThe air suspension operatorseat absorbs shocks and vibrationsproviding a smoothcomfortable ride. For improved rear visibility during returnpart of cycle, the operator can adjust the seat 15 to the transmission and steering controls move with the seatfor increased operator comfort. The operator seat is alsotiltable for facilitating down hill dozing. The travel controlconsole has adjustments fore and aft, and for height. With anindependently adjustable armrest, each D475 ASD operatorcan adjust control positions to individual preference,providing optimum operational posture for all control dialEngine revolution is controlled by electric signals, providingease of operation eliminating maintenance of linkage command PPC controlled blade control joystickBlade control joystick uses the PPC (Proportional PressureControl) valve and the same palm command type joystick astravel control joystick.

9 Control SystemSmooth and soft operationD475 ASD-5E0 utilizes a newly designed power train electronic control system. The controller registers the amount of operatorcontrol (movements of lever and operation of switches) along with machine condition signals from each sensor to acculatelycalculate the control of the torque converter, transmission, steering clutches and brakes for optimized machine operation. Theease of operation and productivity of the new D475 ASD-5E0 is greatly improved throughthese new (Electronic Controlled Modulation Valve) controlled transmissionController automatically adjusts each clutch engagement depending on travel conditions such as gear speed, revolution and shifting pattern.

10 This provides shockless smooth clutch engagement, improved component reliability, improved component life and operator ride (Electronic Controlled Modulation Valve) controlled steering clutches/brakesSensors monitor machine operating conditions, and electronically control steering clutches and brakes depending on type ofjob, such as size of load during dozing, incline angle of slope or load, providing smooth and ease of operation by reducingcounter-steering on downhill travel, downshift functionController monitors engine speed, travel gear and travelspeed. When load is applied and machine travel speed isreduced, the controller automatically downshifts to optimumgear speed to provide high fuel efficiency.
