  • Patent number: 10405473
    Abstract: A tillage apparatus for selective primary tillage and seed bed preparation makes use of a selectively moveable primary tillage shank to provide seasonal, in-field and/or on-the-fly flexibility of tillage operation. The tillage apparatus has a cultivator frame, at least one secondary tillage tool mounted on the frame and a primary tillage shank mounted on the frame, the primary tillage shank selectively moveable between a lowered soil engaging position and a raised disengaged position. In a method of tilling or preparing a seed bed, the tillage apparatus is dragged around a field with the at least one secondary tillage tool engaged with the field when secondary tillage of the field is desired, and the selectively moveable primary tillage shank lowered to be engaged with the field when the field is in need of primary tillage or raised to be disengaged from the field when primary tillage is not desired.

  • Patent number: 10051772
    Abstract: A debris clearing apparatus for use with an agricultural implement has a pair of rotatable discs each having a plurality of teeth extending from a periphery thereof. The teeth on the discs each have a profile comprising a leading edge and a trailing edge. The leading edges are sharpened to create cutting edges to cut through crop residue and other debris. The leading cutting edge can be a straight edge with an outer edge formed at the distal tip of the tooth between the leading and trailing edges. Alternatively, the leading cutting edge can be a curved edge with a sharp outer point between the leading and trailing edges. The discs are arranged so that geometric planes containing the first and second discs intersect and the discs are toed-in toward each other relative to a direction of travel of the implement.

  • Patent number: 8985232
    Abstract: An agricultural system includes an agricultural row unit movable on a field between a first soil condition and a second soil condition, the first soil condition having a different soil hardness than the second soil condition. A down-pressure actuator applies an initial first pressure associated with the first soil condition. A soil-hardness sensing device is positioned at a distance D forward of the row unit and outputs a soil-hardness change signal when detecting a change from the first soil condition to the second soil condition. At least one memory device stores instructions that, when executed by at least one processor, cause the down-pressure actuator to change, in response to receiving the soil-hardness change signal, the initial first pressure to a different second pressure when the row unit encounters the second soil condition.

  • Patent number: 6776107
    Abstract: Apparatus comprising a frame carried by an elongated and laterally extending bar and having mounted thereon a first pair of rotatable trash wheels and a second pair of rotatable trash wheels longitudinally spaced behind the first pair of rotatable trash wheels and forward of a furrow opener. The first pair of rotatable trash wheels is angularly disposed toward each other forming a first angle therebetween and staggered such that one rotatable trash wheel contacts soil forward of the other rotatable trash wheel. The second pair of rotatable trash wheels is angularly disposed toward each other forming a second angle therebetween greater than the first angle. The apparatus cuts and clears trash from minimally and untilled soil.

  • Patent number: 6761120
    Abstract: An agricultural primary tillage implement is disclosed with a row cleaner assembly attached in front of the shank. That row cleaner is adjustable fore-and-aft for optimum clearance between the shank and a leading soil preparation apparatus to maximize clearance for residue movement. The row cleaner is also adjustable for depth. The row cleaner assembly reduces the amount of residue in line with the shank path (row) and creates smaller clod sizes of soil in line with the shank swath, resulting in a better seedbed and faster warm up in the spring, enabling the planter to run in cleaner soil, preventing planter plugging and uneven seed planting depth as well as resulting in better seed-to soil-contact.

  • Publication number: 20020078869
    Abstract: A method for clearing trash from a furrow opener path comprises moving first trash from a first path with a front finger wheel and then moving second trash from a next path on top of the first trash with a rear finger wheel. An apparatus for practicing the method comprises a front finger wheel rotatably mounted to the apparatus and oriented to move trash from a first path to a first side of the apparatus. A rear finger wheel is oriented to move trash from an adjacent second path to an opposite second side of the apparatus. The finger wheels are mounted such that bottom edges thereof are maintained at a substantially constant vertical position relative to the ground by at least one depth control wheel rolling along the ground on the first path cleared by the front finger wheel.

  • Patent number: 6406391
    Abstract: A tensioning device for traction device, particularly chains, comprises an element, particularly a tension shoe (1) that tensions the traction device. The tension shoe (1) is mounted on a pivot axle (2) for pivoting relative to a base element (3), and a spring element (4) acting between the tension shoe (1) and the base element (3) urges the tension shoe (1) against the traction device. To simplify the assembly of the tension shoe (1) and the base element (3), it is proposed that one of the elements (1, 3) comprises at least one mounting eye (6, 11) having a radial mounting aperture (7, 12) for radially receiving the pivot axle (2) arranged on the respective other element (1, 3).

  • Patent number: 5802995
    Abstract: A planting unit utilizing a single disk opener supported for rotation about a horizontal axis offset at a small angle from the transverse direction for opening a furrow. A seed tube assembly is located adjacent the rearward facing side of the disk and includes a runner extending forwardly of the lower portion of the seed tube for holding loose soil out of the furrow in advance of seed or other material deposited therein, the runner being located in the shadow of the disk so as not to significantly contact or disturb the side of the furrow. The opener is mounted on an arm which is pivotable about a relatively low point so as to be oriented at a relatively flat angle with respect to the ground and to maintain the general orientation of the opener as it moves through the soil throughout the range of pivotal movement of the arm. The planting unit can include one or more pivotable press wheels which can be mounted for pivotal movement about the same axis as a pivotable gauge wheel adjusting arm.
