A remote control automatic gate assembly includes a hinged gate having a drive motor and track constructed on the gate itself with a sliding trolley connected to an adjacent post by a normally fixed length control arm. An automatic latching mechanism is provided which is operative in responsive to overtravel retracting movement of the trolley. The overtravel retracting movement of the trolley is taken up by slack adjustment mechanism to enable the gate to remain in its closed position during latching and unlatching of the gate.
