The operator can select the transmission cut-off pressure desired for the left brake pedal using the switch located on theright-side control panel. Automatic transmission with ECMV (Electronically ControlledModulation Valve) automatically selects the proper gearspeed based on travel speed, engine speed, and other travelconditions. The ECMV system engages the clutch smoothlyto prevent lags and shocks when shifting. This systemprovides efficient machine operation and a comfortable ride. Higher cut-off pressure allows the transmission to remain engaged at higher engine rpm/hydraulic pressure...
