Abstract
Primary and secondary hood latches are used on a tractor hood assembly designed to roll forward on the tractor frame. Both the primary and secondary latches are unlatched through the use of either a cable operated or a lever operated independent linkage means. Both latches must be unlatched in order to allow the hood to be opened while either latch may be used to maintain the hood in a closed position.
