Abstract: A tillage machine has an undercarriage that utilizes a triple axle walking beam wheel assembly for each load-supporting wheel assembly of the center section of the machine. Hydraulically powered lift arms are connected with the wheel assemblies to raise and lower the chassis of the machine as the wheel arms are swung downwardly and upwardly relative to the chassis. Each wheel assembly includes a primary walking beam pivoted to the lower end of the wheel arm, and a secondary walking beam pivoted to the rear end of the primary beam. A single front wheel is disposed at the front end of the primary beam, while a pair of wheels are disposed on the secondary beam on opposite fore-and-aft sides of the pivot connection with the primary beam.

Abstract: A land roller implement has a center frame and a center roller. Wings are pivotally mounted to a wing bracket pivotally mounted to, and extending rearward from, each side of the center frame. The wings and center frame thus move independently up and down when operating. The bracket is locked and wheels mounted on the brackets move the rollers up for transport. Inner and outer rollers on each wing are aligned and separated by a roller spacing. An overlap roller rolls over the spacing. In transport position the right and left wings extend rearward from the center frame and right and left overlap rollers are aligned with, and adjacent to, each other. During a turn, the wings pivot and move closer to each other. To avoid contact with each other the right and left overlap rollers move forward and rearward to offset positions.

Abstract: A support or hitch box supports a mounting bar in a selected vertical position. The mounting bar is received in a standard hitch receiver of any car, truck or other vehicle. A plow head is a light weight, strong, box like structure with oppositely directed mold boards so that the plow can operate in both forward and reverse directions. A linkage permits the mold board to be raised or lowered relative to the hitch box. The linkage includes upper and lower links to maintain the vertical orientation of the mold board. The plow head is mounted for pivoting in a horizontal plane. A pivot driver is user controlled to pivot the plow head and a lift driver is user operated to raise and lower the plow head. The plow head carries indicator lights. A spring, preloaded by the lift driver, applies a continuous down force to the plow head when it is the lower, plowing position.

Abstract: An apparatus, system and method for moving a scraping device are provided. The scraping device has a frame, a blade attached to the bottom of the frame, a tongue attached to a front end of the frame and a beam attached to a back end of the frame. Tires are connected to the beam. The scraping device has a front lift mechanism at the front end of the frame and/or a rear lift mechanism at the back end of the frame. The front lift mechanism has a front cylinder connected to the tongue and the front end of the frame. The rear lift mechanism has a rear cylinder attached to the back end of the frame. Movement of the front cylinder and the rear cylinder results in raising and/or lowering of the corresponding ends of the frame of the scraping device. Raising and/or lowering of the front end and/or the back end of the frame adjusts the angle of the frame relative to the ground, adjusts the angle of the blade relative to the ground and/or adjusts the ground clearance of the scraping device.
