Abstract
A locking hitch ring apparatus includes a hitch ring member adapted at a rear end thereof for attachment to a towed vehicle. A drawpin hole defined by the hitch ring member is oriented such that an axis of the drawpin hole is oriented vertically when the hitch ring member is attached to the towed vehicle. A lock plate is movably attached to the hitch ring member such that the lock plate is movable from a closed position, where the lock plate blocks the drawpin hole, to an open position, where the drawpin hole is open, and a lock mechanism is operative to lock the lock plate in the closed position.
