Abstract
A wheel loader automatically adjusts the bucket angle with respect to the ground. The wheel loader includes a hydraulic pump, a tilt cylinder and a tilt valve, a detector which detects that the tilt cylinder is at a control origin, a target setting device which sets a target value for the length of the tilt cylinder, and a control device. The control device calculates a required oil amount for the tilt cylinder to arrive from the control origin to the target length, calculates an oil amount distributed to the tilt cylinder after it has arrived at the control origin, and stops the operation of the tilt cylinder when the distributed oil amount reaches the required amount.
