Abstract: An earth working implement has a main frame, a main blade supported on the main frame transversely to the forward direction, and two wing blades pivotally supported at opposing ends of the main blade for movement between forward and rearward projecting orientations. A tilt actuator controls angular orientation of the main blade relative to the main frame about a lateral axis. Two rear wheels support the rear end of the frame for rolling along the ground. A hitch arm extends forwardly from a pivotal connection of the main frame for connection to a towing vehicle so as to vary in angular orientation relative to the main frame independently of the main blade. Furrow openers in a laterally spaced apart row are movable relative to the main frame between a working position protruding below the cutting edge of the main blade and a raised storage position.

Abstract: A jack assembly for mounting on the hitch arm of a wheeled implement frame supports the wheeled frame relative to a ground surface upon which the wheeled frame is engaged. A jack frame of the assembly is fixedly mounted onto the implement frame and pivotally supports a leg for movement between a raised transport position and a lowered position to support the implement frame elevated above the ground when stationary. A first catch on a retainer member pivotal on the jack frame cooperates with a second catch on a link member pivotal on the leg. A linear actuator coupled between the jack frame and the link member acts to both (i) release the catches and extend the leg towards the lowered position, and (ii) engage the catches and raised the leg towards the raised position.
