Abstract
An auxiliary tag axle assembly for a work vehicle such as a ready-mix concrete truck which is positionable via actuation of a linear actuator to extend the wheel assembly from the rear end of the vehicle's frame to a ground engaging disposition and retractable to a stowed position where the wheels straddle the rear end of the frame and with the auxiliary axle elevated to a position above the level of the bottom of the frame. The need for plural actuators is obviated by utilizing a flexible cable of a predetermined length to effect desired movement of the working parts upon extension and retraction of the main linear actuator.
