Abstract: The farm tractor lift arm lock is an anti-sway brace for a tractor that keeps the lift arms of a traditional three-point hitch from spreading excessively and keeps the angle between the arms constant. Two brackets attach to each of the lift arms and a rigid anti-sway bar extends laterally between the brackets, keeping the brackets, and thus the lift arms, from moving laterally relative each other. The farm tractor lift arm lock is made of metal and can either have the brackets welded to the ends of the anti-sway bar or can be of one-piece construction.

Abstract: The dispenser progressively empties a tube from one end by applying pressure to the other end. The dispenser comprises a support on which the tube rests. A handle is pivotally mounted on the support and has a range of reciprocating movement between first and second pre-determined points for applying an increment of pressure to one end of the tube. A ratchet is connected to the handle and permits the roller to move incrementally forward against the tube exerting pressure thereon during each reciprocation. As the handle moves between the first and second pre-determined points, it moves to an intermediate point defined relative to the point where the handle is pivotally mounted on the support and beyond the point to an over-center position where the roller releases sufficient pressure on the contents of the tube to prevent residual emptying or dripping.
