ABSTRACT A tractor unit for wheeled vehicles having fixed draft tongues, the tractor unit including a frame supported at its front end by a pair of laterally spaced steerable drive wheels, and having a supporting leg at its rear end movable between an operative frame supporting position and an inoperative raised position. A support arm extends rearwardly from the frame and is disposed to underlie and support the draft tongue of a vehicle. A locking pin releasably locks the draft tongue to the support arm. The support wheels have generally vertically extending pivot shafts and a generally vertical steering shaft is rotatably carried by the frame intermediate the pivot shafts on a fixed axis. Power transmission mechanism operatively con- nects the steering shaft with the pivot shafts, and is respon- sive to rotation of one of the pivot shafts in either direction of steering movement away from a neutral position to rotate the other pivot shaft in the same direction but to a different angular extent.
