A disabled truck recovery unit is detachably mountable on the back of a standard truck tractor to permit the standard truck tractor to be operable to tow a disabled truck tractor over the highway in a safe and effective manner. The disabled truck recovery unit includes an anchoring frame assembly connected to the standard truck tractor and an attaching frame assembly that can be connected to a disabled truck tractor to permit the towing thereof. The two frame assemblies are pivotally connected and powered by a single hydraulic actuator to convert the frame mechanism from a compact transport configuration to an operative position to engage the disabled truck tractor. A scissors linkage mechanism interconnects the hydraulic cylinder and the frame assemblies to effect proper movement thereof. An engine is mounted on the anchoring frame assembly to provide an independent source of operative power for the hydraulic cylinder.
