Abstract:
A working vehicle includes: a vehicle body; and a boom; a bucket; a boom driving unit including a boom cylinder; a bucket driving unit configured to swing the bucket; a boom-bottom pressure sensor configured to detect a boom-bottom pressure of the boom cylinder; and a working equipment controller configured to control at least one of a lift motion of the boom and a tilt motion of the bucket. The bucket includes an inclined portion. The working equipment controller controls the lift motion or the tilt motion by comparing a threshold set in accordance with an inclination angle of the inclined portion with the boom-bottom pressure.
