<P>PROBLEM TO BE SOLVED: To eliminate concern for causing breakage of an engine output shaft, burning out of transmission belt to a clutch resulting from a high torque occurring immediately after an operation unit drive in a working vehicle and to maintain and improve operation efficiency. <P>SOLUTION: The working vehicle transmits power from an engine mounted on a traveling machine body through a hydraulic continuously variable transmission to a traveling unit, and directly transmits the power to an operation unit, and the working vehicle includes an operation clutch for connecting and disconnecting a power transmission to the operation unit and a clutch operation member for operating connection and disconnection of the operation clutch. When the clutch operation member is engaged, the hydraulic continuously variable transmission is driven in an acceleration direction and the traveling speed of the traveling unit is maintained while reducing the number of revolutions of the engine to a preset target number of revolutions. <P>COPYRIGHT: (C)2010,JPO&INPIT |
