Control system for latch that secures loader yoke member to tractor front-end weight bracket or bumper

摘要

A tractor-mounted loader includes a yoke member having legs joined by a bight member that carries a latch that is L-shaped in cross section and is pivotally mounted for movement between a closed position, wherein a first leg of the latch extends generally horizontally above and is engaged with a front-end weight bracket of the tractor carrying the loader, and an open position wherein the first leg is located in a generally upright position forwardly of the bracket. A control rod extends along one of the legs of the yoke member and has its forward end connected to the latch so that rearward and forward shifting of the rod respectively moves the latch to and from its closed position. A cylindrical lock member is adjustably threaded onto the rear end of the rod and is received for movement along a slot provided in the a rear portion of the one yoke member leg and is dimensioned for fitting closely in an enlarged rear end portion of the slot to establish a locked condition in the rod which corresponds to the closed position of the latch. A necked down intermediate section of the lock member is movable into register with the slot to permit the latch rod to be moved forwardly to place the latch in its open position.
