Abstract: A latching arrangement for an agricultural implement having components which may be retracted or folded from an extended operational position to a stowed position better suited to transport and/or storage including a first remotely operable actuating mechanism for moving a component between the stowed and extended positions, a lever having a component engaging hook near one end and a fulcrum fixed to the implement, and a second remotely operable actuating mechanism for selectively engaging the hook and component only when the component is in the stowed position. The second actuating mechanism is operable independently of, and from the same location as, the first actuating mechanism. The second actuating mechanism comprises a hydraulic cylinder fixed to the implement and having a piston rod coupled to the lever near a lever end opposite the hook.

Abstract: An agricultural tillage implement has a main frame section, a left wing section, and a right wing section. Lift wheels and gauge wheels are actuated by hydraulic cylinders supplied by a hydraulic system. Solenoid valves connect groups of hydraulic cylinders to each other and to bypass circuits.

The hydraulic system has at least one hydraulic flow divider and combiner dividing hydraulic flow and pressure between at least one left hydraulic circuit and at least one right hydraulic circuit. The at least one hydraulic flow divider and combiner functions to coordinate the motion of the left rear lift wheels and gauge wheels, and the right rear lift wheels and gauge wheels, and may be overridden by bypass valves.

Abstract: A large field cultivator has forward and rear wing frames that are articulated to a main frame between a field position in which they extend laterally and a transport position in which they pivot forward and rearward about an axis substantially perpendicular to the plane of the frames in the field position. A pair of flip up frames secured to the aft frames pivot out of the way so that the rear wing frame assemblies may be pivoted inward to the transport position.
