6 Transmission gearshifting is simplifiedwiththumb push adjustablesuspension seat andtravel control consoleFor improved rear visibilityduring return part of cycle, the operator can adjust the seat15 to the right. The transmission and steering controlsmove with the seat for best operator comfort. The operatorseat is also tiltable for facilitating down hill dozing. Thetravel control console has adjustments fore and aft, and forheight. With an independently adjustable armrest, eachD475A operator can adjust control positions to his individualpreference, providing optimum operational posture for 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.

Theease of operation and productivity of the new D475A -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. This provides shockless smooth clutch engagement, improved component reliability, improved component life and operator ride (Electronic Controlled Modulation Valve)
