Abstract: A working vehicle (1) includes: a vehicle body (2); and a boom (31); a bucket (32); a boom driving unit including a boom cylinder (36); a bucket driving unit configured to swing the bucket (32); a boom-bottom pressure sensor (460) configured to detect a boom-bottom pressure of the boom cylinder (36); and a working equipment controller (10) configured to control at least one of a lift motion of the boom (31) and a tilt motion of the bucket (32). The bucket (32) includes an inclined portion (44). The working equipment controller (10) controls the lift motion or the tilt motion by comparing a threshold set in accordance with an inclination angle of the inclined portion (44) with the boom-bottom pressure.
