Provided is a wheel loader capable of moving up a lift arm in a short time during excavation work. A wheel loader comprises a controller configured to control maximum traction force of the wheel loader and input torque of a working device hydraulic pump, and include a specific condition determination section configured to determine whether a specific condition for specifying excavation work is satisfied, an elapsed time measurement section configured to measure an elapsed time from start of the excavation work, and an input torque control section configured to limit the input torque to a first input torque value when the specific condition is satisfied and increase the input torque from the first input torque value when a second set time elapses from the elapse of a first set time.

Wheel loader

The work vehicle includes: a working device; an auxiliary machine; and a priority valve that is switched between a normal position for directing pressure oil from an accessory pump toward the auxiliary machine and a merging position for directing the pressure oil from the accessory pump toward the working device. The work vehicle includes a control device that holds the priority valve in the normal position in case either the forward direction or the reverse direction which is indicated by a forward reverse operating device and a travel direction of the work vehicle do not match each other, and that switches the priority valve to the merging position in case either the forward direction or the reverse direction which is indicated by the forward reverse operating device and a travel direction of the work vehicle match each other and an operating device is in an operated state.
