Abstract: The invention has been designed to be applied to conventional agricultural tillage equipment. The invention provides a new and improved mechanism for lifting and lowering, controlling and maintaining an accurate level of the equipment. It consists of a single hydraulic cylinder powering a scissor-type mechanical principle designed in such a configuration that the power provided by the hydraulic cylinder is transferred to each pivoting axle. The advantage of the device is that it is a relatively light weight arrangement while retaining stability and rigidity of the arrangement in operation.

The apparatus includes a rigid structural frame mounted on a single elongated supporting roller extending substantially the entire width of the apparatus. A plurality of transversely extending beams are fixedly secured to the frame and each carries a plurality of vertically extending earth working tines. The frame is vertically adjustable on the roller to a selected elevation and a leveling mechanism is interconnected between the frame and a towing bar to enable pivoting of the frame about the single roller to a horizontal plane when the towing bar is connected to a towing vehicle.

Abstract: A transport lock system for an implement or the like having a frame and transport wheels movable between lowered transport positions wherein the frame is raised for transport and raised positions wherein the frame and ground working tools thereon are lowered for an operating mode, and having a fluid pressure operated cylinder operative to move the transport wheels between their raised and lowered positions. The transport lock system includes a lock link and locking pin which are selectively cooperable to prevent an operator from lowering the frame during a transport mode and includes a flow control valve operative in response to movement of the locking pin to a locking position to prevent the operator from inadvertently applying fluid pressure to the cylinder in a manner to lower the frame. The control valve is operative in response to movement of the locking pin to a non-locking position to enable actuation of the cylinder to raise and lower the frame.

Abstract: Hydraulic center and lock structure for the caster wheel of, for example, a tractor-drawn plow, operative on a centering element rigid with the standard of the caster wheel for forcibly centering the standard and ultimately locking the standard against turning about its axis when the caster wheel is in its straight-ahead position. The hydraulic device is bi-directionally operative for disengagement from the centering element to enable free castering of the wheel, as when the plow is raised for transport. The invention also provides two forms hydraulic control for coordinating the raising and lowering of the plow with unlocking and locking the caster wheel. In one form, the system provides for trapping fluid in the caster wheel cylinder in its straight-ahead position, with a separate valve operated manually to release the fluid when the plow is lowered to operating condition. In another form the valve that releases the trapped fluid is made responsive to a predetermined pressure.

Abstract: A tractor-drawn farm implement is carried at its front end on a tractor drawbar and at its rear end by trailing wheel means, and linkage of the so-called four-bar type is operative to selectively raise and lower the implement. The body of the implement serves as one member of the linkage and front and rear lever arms are interconnected by a leveling rod so as to coordinate the front and rear arms as force is exerted against one arm by power-operated means on the implement. During one phase of vertical movement of the implement as it is raised or lowered, the leveling rod is stressed in compression. The invention provides yieldable means in conjunction with the rod capable of yielding as to prevent or at least minimize bending of the rod in the event of over-stressing.

A hydraulic ram is operably connected between each frame and the associated wheel assembly with the rams connected in parallel and with a rotary flow divider interposed in the connection with one end of said rams, whereby fluid pressure is directed to said one end when connected with a pump and fluid is exhausted from said one end when connected with a reservoir. Flow to and from said one end being at substantially equal rates regardless of the relative resistance encountered by said rams.

Abstract: A drawn moldboard plow includes a lift linkage for the rear furrow and ground wheels which improves ground penetration by causing the plow frame to roll as it is lowered so the share points contact the soil first. A hydraulic cylinder contained within a part of the frame operates both the furrow and the ground wheels through a linkage which, during retraction, raises the ground wheel at a faster rate than the rear furrow wheel so the plow frame rolls in the direction of the ground wheel. If the ground wheel reaches its plowing position determined by an adjustable stop before the furrow wheel, a lost motion connection allows continued retraction of the cylinder to further raise the furrow wheel to its plowing position.

Abstract: A transversely and linearly elongated tractionally supported tool-carrying frame for agricultural implements having caster wheels which are shiftable individually and vertically relative to the frame to move the latter, and consequently the tools, between raised inoperative and lower earth-working positions. A central tractor hitch on the frame enables the latter to be pulled in broadside fashion forwardly for earth-working purposes when the frame and tools are in their lowered earth-working positions, and a second tractor hitch at one end of the frame enables the latter to be pulled linearly sidewise for transport purposes when the frame and tools are raised. A salient feature of the invention resides in a novel arrangement for automatically latching one of the caster wheels against free caster trailing during such sidewise transport movement of the implement to thereby lend a stabilizing influence to the implement and inhibit side sway.

An interconnector cable is wrapped at one end around the rockshaft. As the rockshaft turns and rotates the wheels into the implement working position, the cable pulls the valve stem of a fluid metering valve partially out of the valve, thereby opening the valve and permitting fluid flow.
