A hydraulically-operated latch mechanism is disclosed for releasably maintaining a backhoe in its lowered, working position on an associated material handling implement. In the preferred embodiment, the mechanism includes a movable latch member pivotally mounted on the implement for movement between engaged and disengaged positions. A latch pin is provided on the frame of the backhoe for cooperation with the latch member whereby the latch pin is adapted to be received by the latch member in the engaged position thereof for holding the backhoe against movement relative to the implement. A latch hydraulic motor is provided in operative connection to the pivotal latch member for effecting movement between the engaged and disengaged positions. Notably, the latch member is configured to define wedge-shaped openings which provide a gripping action when the latch member is in its engaged position so that a very rigid connection is formed between the backhoe and the implement when the backhoe is in its working position.
