A hydraulic latch arrangement is disclosed for facilitating efficient movement of a backhoe between working and transport positions relative to an associated material handling implement upon which the backhoe is mounted. The arrangement includes an upper pivot which pivotally connects the frame of the backhoe to the implement for relative movement of the backhoe about a horizontal axis. The arrangement further includes a pivotally movable latch member preferably mounted on the associated implement, and a latch pin mounted on the backhoe frame for cooperation with the pivotal latch member. A hydraulic latch motor is provided for selectively moving the pivotal latch member between engaged and disengaged positions, wherein in the engaged position the latch member cooperates with the latch pin for effecting a substantially rigid connection between the backhoe and the associated implement. In the preferred embodiment, hydraulic fluid conduits are provided which interconnect the hydraulic latch motor with one of the hydraulic rams which operates one of the stabilizers of the backhoe, thus permitting operation of the latch motor attendant to selective fluid pressurization of the stabilizer hydraulic ram.
