| Apparatus and method for shearing a soil layer and removing it is provided. An apparatus in accord with the present invention has a frame mounting a shearing blade reciprocally movable substantially vertically into an operational position where the shearing blade will extend below the ground surface to shear the layer of soil above the shearing blade from the soil beneath it. An apparatus will also have a pushing blade mounted for use in pushing sheared soil. In a method in accord with the present invention, apparatus is provided that includes a shearing blade and a pushing blade. Each of the blades is positionable in operational and non-operational positions. The pushing blade is placed in its non-operational position and the shearing blade is placed in the operational position and is used to shear an upper layer of soil to a desired depth to produce a sheared soil layer and to create a new surface layer below the sheared soil layer. The shearing blade is then placed in its non-operational position and the pushing blade is placed in its operational position and is used to push the sheared soil layer off the new surface layer. | ||||||
| 62 | Wheel supported implement for working and grading soil | US09829736 | 2001-04-10 | US06739404B2 | 2004-05-25 | Kevin V. Keigley |
| An implement for preparing seed beds and lawns, and for grading tracks and show rings, includes a main frame upon which scarifying teeth are mounted to penetrate and scarify the soil, tines which work the soil and prepare the final grade, and a blade for grading soil. The frame is supported on wheels, and attached to a tractor by a three-point hitch. Accordingly, the depth of penetration of the scarifying teeth and the angle at which the tines work the soil, may be adjusted by pivoting the implement about the axis defined by the axles of the wheels by using the tractor hydraulic system. Since this degree of adjustment is limited, the wheels are mounted to the frame by an adaptor plate including multiple openings, any of which the axle of a wheel to thereby adjust the height of the frame relative to the ground to accommodate both loose or hard soil. The implement may also be attached to the front plate of a front end loader, in which the front plate angle relative to the lift arms of the skid steer loader may be adjusted to effect the depth of penetration of the scarifying teeth and angle at which the tines work the soil. | ||||||

| 74 | Folding land plane | US793593 | 1991-11-18 | US5213165A | 1993-05-25 | Neil C. Dunn; Edward O. Brandt; James E. Burks |
| A multi-section, foldable land plane is foldable between a relatively narrow, transportable position, and a wider, deployed position for leveling field irregularities. A central, wheeled frame is adapted to be drawn by a conventional tractor. The frame, constructed of a network of tubular steel members, supports a pair of lateral wings which can be selectively folded and unfolded over the central frame. Folding of the wings is controlled by a system of hydraulic cylinders. The hydraulic cylinders are coupled to pivotal cam arms that control upward and outward rotation of the wings relative to the frame. A deflection compensation system insures proper wing movement during movements. An automatically actuated locking system prevents undesired deflection of the wings during operation. The locking system is activated by a second pair of hydraulic cylinders that control a master locking position that is linked to remote, slave locking positions by an elongated synchronizer. A plurality of rigid plane blades cooperate to define a soil flow pathway beneath the frame. Each of the blades is independently adjustable for height and pre-tension, accommodating the condition of the field. Soil scraped from elevated areas is channeled backwards along the blades and subsequently deposited into depressed areas of the field and compacted by the blades. | ||||||
