<p>BIFOLDING SHIELD FOR AGRICULTURAL HARVESTER A self-propelled harvester or combine is provided with a bifolding panel structure at the lateral side thereof on which a bin unloader tube is swingable from an outwardly extending unloading position to a transport position alongside the panel structure. When the unloader tube is in its transport position, the lower part of the panel structure can be pivoted about its pivot connection with the upper part of the panel structure between closed and open positions, but the unloading tube in its transport position prevents opening the upper part of the panel structure. When the unloader tube is raised, the upper part can be moved from its closed to its open position. A linear air spring or actuator biasingly maintains the lower part of the panel structure in whichever of its open and closed positions it is placed, and when the upper part is swung to its open position, it is maintained in that position by the linear actuator. In an alternate embodiment of the invention, the linear actuator biasingly holds the upper part of the panel in its closed position when placed there.</p> |
