Abstract:
1. A working vehicle comprising an engine, a splitter for dividing an output of the engine between a working apparatus system and a traveling system, a clutch connected to said engine via the splitter, a torque converter connected to the clutch, a transmission connected to the torque converter and transmitting drive force to drive wheels, a vehicle speed detection means which detects actual vehicle speed, and a controller which performs control so that the actual vehicle speed detected by the vehicle speed detection means becomes equal to a target vehicle speed set in advance, wherein said controller comprises: a target drive force calculation means which calculates a target drive force required for implementing said target vehicle speed using a standard traveling resistance set in advance and vehicle body weight; a target input rotational speed calculation means which calculates a target input rotational speed, being a target value for rotational speed to be inputted to said torque converter to provide the calculated target drive force; an actual input rotational speed detection means which detects an actual rotational speed inputted to said torque converter; and a clutch pressure setting means which sets a clutch pressure for said clutch so that the detected actual input rotational speed becomes equal to said target input rotational speed.
