Claim 3:
4. The wheel loader according to claim 1, further comprising:
a hydraulic pump that supplies hydraulic oil to a hydraulic cylinder that drives the bucket; and
a discharge pressure sensor configured to detect discharge pressure of the hydraulic pump,
wherein the controller is further configured to determine the rear wheel lifting state in cases where the temporal change rate of the operation state of the bucket detected by the operation state sensor is the first temporal change rate, where the temporal change rate of the inclination state of the vehicle body detected by the inclination state sensor is the second temporal change rate, and where the discharge pressure of the hydraulic pump detected by the discharge pressure sensor becomes discharge pressure necessary for the tilt operation of the bucket during the excavating operation.
