Claim 1:
2. The tractor according to claim 1, wherein, in the adherence amount acquisition process, the control device drives the electric motor in a state where the work machine takes the retracting posture, the control device derives an inertia estimated value as an estimated value for inertia of the rotating body based on a torque of the electric motor and a change velocity of a rotation number of the electric motor to be obtained when the electric motor is driven in the state where the work machine takes the retracting posture, and the control device acquires, as the estimated adherence amount, a value to be larger as the inertia estimated value is larger.
