  • Patent number: 8287433
    Abstract: A work vehicle includes an engine, a travel mechanism, a clutch, an inching operation member, and a controller. The travel mechanism is configured to cause the vehicle to travel. The clutch is configured to selectively transmit drive force from the engine to the travel mechanism. The inching operation member is configured to be operated to create slippage in the clutch to reduce vehicle speed. The controller is configured to calculate load of the clutch during inching, and to reduce a rotational speed of the engine when the calculated load of the clutch during the inching exceeds a predetermined threshold.
    Type: Grant
