A control device (40) of a wheel loader calculates a first ratio, which is the ratio of a value corresponding to the target travel distance that serves as the target when the wheel loader travels to a position at which excavated objects are discharged after excavation by the bucket, and a value corresponding to the target elevation amount that serves as the target when the boom is raised after the start of movement. The control device (40) also calculates the difference between the first ratio and a second ratio, which is the ratio of a value corresponding to the actual distance the wheel loader travels after the start of movement to the position at which excavated objects are discharged after excavation by the bucket, and a value corresponding to the actual amount the boom is raised after the start of movement. The control device (40) then controls the transmission torque that is transmitted from the engine to the drive wheels such that the difference between the first ratio and the second ratio is zero.
