A trailer hitch comprising two arms pivotally supported upon the mounting means by which a lift mechanism is supported upon a vehicle. The arms are movable between substantially parallel positions adjacent the mounting means, where they do not interfere with the upward and downward movement of the lift mechanism, and extended positions in which their free ends are interconnected, one of said arms supports a hitch ball and both said arms include means whereby the same pin can hold the arms in either the extended positions or the retracted positions.
