Using recent innovations in electro/hydraulic proportional control, power train engineers have been able to accomplish improvements in agricultural tractor powershift transmissions. These provide smooth, consistent transfer of power regardless of gear speed transition range under all loads and operating conditions. An additional benefit provides for electronically duplicating the conventional mechanical clutch foot pedal inching feature used during implement load-up. Smooth vehicle inching control is retained to duplicate mechanical operation. These features provide ease of operation and comfort for the operator. Additional benefits include longer clutch, transmission, and driveline life.
