Abstract: A cylinder mounting arrangement for a folding implement includes reversible L-shaped plates supporting an auxiliary tube above a transverse tool supporting beam. The attaching location on the beam can be changed to avoid interference with the desired tool spacing by reversing the plates. The same plates and auxiliary tubes can be used on a number of different implements and with different main frame widths to reduce manufacturing costs and the number of parts that have to be stocked. The reversible plates can be selectively mounted on the main frame with the plates inside or outside of the fore-and-aft tubes connected to the transversely extending tube, depending on the tool placement on the main frame. Therefore, a wide variety of tool spacings can be accommodated in the region under the tube and between the fore-and-aft tubes.

Each row is transversely displaceable by a double acting hydraulic ram relative to the frame. The rams are controlled by an operator supported by the frame in a position to have a direct view of the weeding implements. Each implement is free to move up and down independently of the remaining implements in order to follow the ground contour. The implements of any one row can be raised together out of working position. These weeding implements can be earth working discs and/or thermal weeders.

Actuation of the motor causes the slide member to slide on the rails.

Abstract: Asphalt cutting apparatus for breaking up and windrowing old asphaltic pavement on a roadway or the like including the pavement adjacent to a curb or gutter. A plurality of laterally spaced, sharpened cutter discs are freely rotatably mounted on a support carriage. The support carriage is attached to a frame pivotally coupled at a forward pivot to a prime mover such as a truck or similar vehicle for movement along the asphalt surface. As the cutter discs are moved along the asphalt surface a hydraulic clamp cylinder provides a vertical movement about the forward pivot to vary the depth of cut and also maintains a downward pressure on the cutter discs and forces the discs to roll through and cut up the asphalt.

Abstract: A material handling assembly has a frame for attachment to the three point hitch of a tractor. A laterally swingable boom extends rearwardly from the frame and has an upright shaft at its rear end rotatable about an upright axis for suspending a reversible scraper blade whose angularity may be varied as the shaft is rotated. The blade is releasably attached to and tiltable relative to the shaft. All four functions of raising and lowering the frame, swinging the boom, varying the angularity of the blade and tilting the blade are hydraulically controlled. A special four bar linkage coupled with the shaft provides for wide blade angularity adjustment. A fluid bypass arrangement interconnects the swing and angularity functions to accommodate for excessive loads which may be encountered when the attitude of the blade is to be varied in accordance with desired grading operations.

Abstract: The disclosed Power Shift Mechanism is adapted to laterally shift an earth working implement, such as a vertical plow, relative to a tractor or the like. In the disclosed embodiment, the plow is mounted on a slide bracket and the bracket is slideably mounted on a support frame. The shift mechanism includes a fluid operated piston-cylinder connected between the frame and a pivot link pivotally connected to the slide bracket. The pivot link may be rotated by the piston-cylinder to either of two positions and locked in place by releasable connectors. The piston-cylinder will then rotatably shift the pivot link or laterally shift the bracket and the earth working implement. The shift mechanism thus increases the effective stroke of the piston-cylinder and reduces the power requirements of the shift mechanism.

As the piston expands and contracts relative to the cylinder, the tops of the plates are displaced in the same direction.

Abstract: An improved blade clamping mechanism for a motor grader blade which has blade support rails carried in pivoted blade support means for lateral sliding movement, and in which confining surfaces in the blade support means restrict both vertical and fore-and-aft movement of the rails in the support means. A clamp lever is pivoted on the circle of the motor grader and has a clamp arm which can be turned in a vertical plane against the bottom of the lower support rail with a high mechanical advantage to force the rail against an overlying confining surface; and a single action hydraulic cylinder and piston unit which turns the lever simultaneously presses a clamp shoe against the rear of the upper support rail. The clamps are normally locked by hydraulic pressure on the piston, and released by moving a manually controlled valve to a drain position so that a return spring acting on the clamp shoe can move the shoe and the lever to a release position.
