摘要

In order to improve fuel economy and suppress the delay of the increase of the engine rotation speed and the decrease of the operation speed of a working machine by properly allocating driving force from an engine between a travel device and the working machine with high transmission efficiency when a working vehicle is started, disclosed is a working vehicle wherein a control unit (10) controls the switching of a lockup clutch (27) by controlling lockup oil pressure. The control unit (10) executes lockup slipping control for bringing the lockup clutch (27) into a slipping state when the vehicle is started. The control unit (10) controls the lockup oil pressure on the basis of working machine load information such as the position of a boom operation member while the lockup slipping control is being executed.
