The coupler is attached to the boom of a tractor or other vehicle and enables the boom to be quickly and automatically connected to an implement such as a loader bucket. The coupler includes spring-loaded and laterally shiftable pins which automatically latch to the implement when the coupler is shifted forwardly toward the implement. Unlatching of the pins is effected by manually turning an operating handle. The operating handle is connected to the pins by laterally rigid links which cause movement of the handle to follow movement of the pins in all positions of the pins so that the position of the handle serves as a visual indicator as to whether the pins are latched or unlatched.

A coupling for use in detachably connecting a movable boom to a back side of an implement and having manual and quick connect coupling modes for connecting the boom and implement, said coupling comprising a bracket having means adapted for pivotal connection to said boom, said bracket having a laterally extending connector adapted to be releasably coupled to said implement, a housing connected to said bracket and supporting said connector to slide laterally inwardly to an unlatched position and laterally outwardly to a latched position, a manually operable actuator accessible from outside of said housing and rotatably supported by said housing for movement between unlatched and latched positions, said actuator also being translationally movable with respect to the housing, a laterally rigid link located in said housing and pivotally connected to said actuator and said connector, said link being operable upon manual rotation of said actuator toward its latched position to push said connector toward its latched position for manual coupling and being operable upon manual rotation of said actuator toward its unlatched position to pull said connector toward its unlatched position for manual uncoupling, a spring urging said connector toward its latched position and yielding to enable said connector to move toward its unlatched position in the quick connect coupling mode independently of manual operation of said actuator, the actuator being unrestricted so that it is free to be driven in rotation through said link by movement of the connector inwardly toward its unlatched position during the quick connect coupling mode to rotate the actuator toward its unlatched position thereby to indicate the position of the connector, said link causing said actuator to turn from its latched position toward its unlatched position whenever said connector is moved toward its unlatched position independently of manual operation of said actuator.
