  • Patent number: 5692855
    Abstract: 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.
