ABSTRACT:
Apparatus for coupling a front end loader to a tractor comprising a longitudinally extending loader mounting frame for pivotally supporting a pair of loader boom arms. The frame comprises a pair of transversely spaced support arms, and a pair of forwardly extending members affixed to the support arms. A pair of front mounting pins extend from the tractor for coupling the forwardly extending members of the frame to the front of the tractor. A pair of rear mounting pins extending from the tractor, cooperate with a latch assembly for coupling each transversely spaced support arm to a corresponding mounting pin under conditions where the forwardly extending members are coupled to the tractor. The latch assembly includes a notch in each of the support arms for receiving a mounting pin and a latch plate for holding the pin in the notch under conditions where the pin is received by the notch. The latch plate is pivotally mounted on the support arm for automatic movement between open and closed positions under conditions where the mounting pin is received by the notch. A translatable holding rod moves from a disengaged position to an engaged position for holding the latch plate in the closed position.
