A mixer vehicle (1) is provided with a drive device (4) which rotationally drives a mixer drum (2), a drive state detector (5c, 10b) which detects the drive state of the drive device (4), a rotation sensor (6a) as a drum rotation detector which detects the rotational speed of the mixer drum (2), and a controller (20) which outputs a drive command value to the drive device (4) so that the rotational speed of the mixer drum (2) is a target rotational speed. The controller (20) has an abnormality determination unit (21) which, when the difference between the rotational speed of the mixer drum (2) and the target rotational speed is greater than or equal to a predetermined reference value, identifies the location of an abnormality on the basis of a drive command value, a value detected by the rotation sensor (6a), and a value detected by the drive state detector (5c, 10b).
