ABSTRACT:
A jack for snow plow frames is attachable thereto forwardly of the ears of the frame through which and corresponding ears on the front end of a truck attaching pivot pins extend when the pin receiving holes in the ears are in registry. A jack unit attachable to a snow plow frame has transverse arms attachable to the frame and a central hub through which a jack screw is threaded at right angles to the arms and which is rotatable relative to the frame to enable the jack screw to be swung into and out of a ground-engaging vertical position and adjusted to maintain the frame in the position it was in while the plow was being disconnected from the truck and to be raised and lowered, if necessary when the plow is again to be connected to the plow frame.
