A hitch for a vehicle such as a track tractor, wheeled tractor or the like for attachment to a device to be drawn by the vehicle such as a snow roller, harrow or other drawn implement or towed load which does not interfere with manual or power steering of the vehicle by the customary steering devices and which, at the option of the operator, may be used to assist him in steering and also to steer the vehicle without using the customary manual or power steering devices. The preferred embodiment of the hitch also includes means by which the pressure of the device which is being drawn upon the surface of the earth, a snow surface or the like, may be varied to increase or decrease the effectiveness of the device in assisting in steering the vehicle with the manual or power steering devices or in steering the vehicle without using the customary steering devices. The hitch is also designed to accommodate power driven shafts to transmit power from the vehicle transmission to drive the device which is being drawn, which are so positioned relative to the vehicle and to the elements of the hitch that the need for universal joints and the like are eliminated.
