Abstract: A system for uniformly erasing soil indentations made by the wheels of agricultural equipment. The erasing elements are pulled behind the wheels of the agricultural equipment and are pivotally attached to the frame thereof thereby preventing the relative distance between the frame and the soil from affecting the depth of penetration of the erasing elements. The eraser elements are arranged such that they engage the soil behind the wheels of the equipment and penetrate the indentations to a depth which is largely determined by the weight of the eraser arm assembly, the consistency of the soil and the forces experienced by the erasing arm as it engages the soil. Accordingly, the cutting depth of the eraser arms are largely unaffected by the unevenness of the terrain. A structure is presented for lifting the eraser system from the soil so that the system may be transported to and from the location of use.

Abstract: A conventional rotary tiller having an engine, an axle with two wheels, a set of tines, handlebars, and an attachment that facilitates turning. The attachment comprises a turntable which is mounted to the tiller opposite the tines in such a way that it remains out of contact with the ground during normal cultivation operations. Turning the tiller is accomplished by pivoting the tiller about the axle onto the turntable, and then rotating the tiller on the turntable to a new direction. The tiller is then pivoted back to resume normal operations in the new direction.

Abstract: A potato lifter, but also being a lifter capable of lifting other especially subterranean vegetation products, such as celery roots, carrots, bulbs, edible onions, etc., the lifter being of the kind comprising an in the ground, under the products, led cutting member and a conveyor positioned behind the cutting member for the upwards guiding of the products is described. A number, and at least one, mainly with plain, smooth or comparatively featureless surface shaped delivery roll or rolls (5, 6, 7, 8) is (are) positioned between the rear edge of the cutting member(1, 2, 3, 4) and the conveyor (9). The delivery rolls, having preferably equal diameters and being driven with a circumference velocity of about the same size as the forward drive velocity of the potato lifter, are positioned rotatable around mainly horizontal axes and, when more than one, positioned rather close together and mutually parallel. The damage introduced at the mechanical lifting to the potatoes is exquisitely low.

Abstract: A vehicle has front brackets which engage with a coupler which has an upright brace with two vertical members joined by a horizontal member. Fixed pins on the brace engage in the bracket slots and retractable spring-loaded pins on the brace engage with the holes on the bracket. A frame is pivotally mounted to the vertical members and is pivotable by an actuator which connects the brace and the frame. A support is pivotally mounted about an axis perpendicular to the frame and has an upturned flange adapted to engage beneath a downturned bracket on the implement and has pinholes located beneath the flange to receive pins extending from the implement. Fixed to the implement is a downturned J-shaped bracket with a vertical portion and a spaced opposed portion which is approximately as deep as the upward extension of the flange on the coupler. Vertical plates are connected on either side of the J-shaped bracket and are spaced to fit on either side of the support of the coupler.

Abstract: A tillage implement which has both deep tillage subsoil shanks at the rear of the machine and relatively shallow running, residue cutting and topsoil mixing discs at the front of the machine provides for expeditious depth adjustment of the discs through spacer blocks that may be inserted between the underside of the frame of the implement and the tops of the gang beams. The blocks are designed to be clamped in position beside pivot bolts and angle retaining bolts of the gangs such that the blocks may be inserted or removed by merely loosening the bolts instead of completely removing the same and without interfering with the ability of the gangs to be angle adjusted fore-and-aft. The configuration of the blocks is such that they may be stacked one upon the other to provide an increased range of depth adjustment without sacrificing rigidity of construction.

Abstract: A depth gauging adjustment mechanism includes a spring-loaded handle which pivots about a common axis with the depth gauging wheel arm on an opener assembly. The handle has two transversely located pins, and the back of the opener assembly has notches on a radius struck on the axis for receiving the pins. The wheel arm and thus the planting depth are maintained by the handle. Each handle position represents a different planting depth which can be adjusted easily with one hand by pulling the handle against the bias, repositioning the pins and then releasing the handle. The wheel arm is freely rockable downwardly from the depth adjusted position to facilitate handle movement when the opener assembly is raised from the ground-working position.

Abstract: The mixing head comprises a pair of opposed, spaced apart, generally vertical discs that are generally aligned with the direction of travel, although they are slightly angled so as to be wider apart at their front ends than at their rear ends. The discs are rotatably mounted to a free floating frame. Each disc has a plurality of radially extending, elongated, broad, rigid, chisel-like teeth which extend from the disc central portion out beyond its circumferential rim. The discs are driven to rotate against the direction of travel. When rotating, the disc and teeth formations operate to cut down into the coil and excavate it in portions carried by the teeth. The portions are moved inwardly by the angled formations and then thrown and dropped to the rear. The furrow formed has a flat-topped ridge overtopped with a loose mix of excavated soil and humus. The furrow is a good growing site for implanted seedlings.
