Abstract: A grading machine may include a machine body, a grading blade, at least one grading blade sensor configured to sense a position and orientation of the grading blade, a drawbar connecting the grading blade to the machine body, at least one drawbar sensor configured to sense a position and orientation of the drawbar, a user interface, and a control system. The control system may be configured to receive an input from the user interface and position and orient the grading blade and the drawbar to one of a plurality of predetermined ditching positions based on the input.

Abstract: A grading device is attachable to skid steer equipment. The device is fashioned as a standard bucket attachment secured to a box or dozer blade. The bucket attachment is configured to secure to the universal attachment arm of skid steer equipment.

Abstract: A tool assembly for an agricultural implement includes a ground-engaging tool mounted to the implement support frame by an assembly of a support post, a mounting bracket and a frame mount. At least one of the support post and the mounting bracket includes a substantially cylindrical rod and a collar having an axial opening configured to receive the rod. An interface arrangement may provide multiple contact areas between the support post and the collar. A recessed pocket may retain a nut that threads onto set screw used to engage the rod, such as at a detent recess, and fix the position of the support post with respect to the mounting bracket. The mounting bracket may provide for alternate fore-aft and lateral mounting orientations.

Abstract: An improved spreader/grader system, which includes a frame having a pair of parallel sidewalls; a plurality of spreader/grader blades positioned between the sidewalls and secured within a slot along the length of each of the sidewalls, each blade having a lower edge for spreading or grading a surface upon which the spreader/grader rests; a hydraulic cylinder attached to each end of each blade to allow each blade to be moveable along the length of the sidewall in a parallel or non-parallel relationship as desired by the operator; and a hydraulic cylinder system for attaching the frame to a vehicle, such as a tractor, for pulling the spreader/grader during the spreading/grading process. The blades of the spreader/grader may alternatively be secured in fixed positions between the sidewalls of the frame with a bolt/nut combination.

Abstract: A box scraper for use with a pulling or a pushing vehicle, having a continuous box-form main frame above, with a lower portion of the rear wall, the moldboard, hinged to the side wall at one end and held to the opposite side wall by a lock mechanism such that one end of the moldboard can be released backwards from that sidewall; when thus released allowing for a smooth and continuous lateral release of scraped materials outside the confines of the scraper box.

Abstract: A full support bearing for a grader circle including a first radial groove in a cylindrical portion of the circle includes a group of inserts forming a second support groove within the first radial groove. It also includes circle supports sized and shaped such that the gap between any two circle supports is small. The circle supports are arranged along a circumference of the circle and rigidly attached to a draw bar. The arrangement results in virtual 360 degree circle support, lower loads, and smaller material deflections at all loaded areas, and significantly increased durability due to a resultant reduction in wear rates.

Abstract: The invention is related to an attachment to a front end loader. The invention comprises a dual blades having a rear frame which is fixed to the movable arm means at the front of the front end\ loader. The rear frame has a pivotal left arm and a pivotal right arm with a left blade mounting frame pivotal mounted to the forward end of the left arm and a left blade spring mounted to the forward end of the left mounting frame. A right blade mounting frame is pivotally mounted to the forward end of the right arm and a right blade spring mounted to the forward end of the right blade mounting frame. A pair of hydraulic cylinders with one mounted between the left arm and the rear frame and with the other mounted between the left arm and the left blade mounting means.

Abstract: A process for and a machine which builds levees in gumbo with moldboards which have knives welded to a blade which makes strips and then lumps of a sheet of gumbo. The machine is attached to a tractor by a three point hitch. The moldboards are adjusted by plates and discs which are connected by bolts in various holes in the plates and discs. A push board is attached to the rear of the machine for repairing damaged levees.

Abstract: A soil-working machine comprising a chassis, a rotor connected to the chassis, driven in rotation during work about a substantially horizontal axis directed transversely to a direction of forward travel of the machine, at least one guard connected to the chassis with an articulation of pivot type, the axis of which is substantially parallel to the axis of rotation of the rotor, and at least one adjustable retaining device which limits, downward only, the angular travel of the guard about the articulation. The soil-working machine additionally includes at least one locking device which limits, upward, during transport, the angular travel of the guard so as to keep the latter in the position defined by the setting of the retaining device.
