  • Down pressure adjustment assembly for a disc opener of an agricultural implement
    Patent number: 8286566
    Abstract: A down pressure adjustment assembly for a disc opener of an agricultural implement includes a rockshaft to which one or more disc opener units are mounted and an actuator that rotates the rockshaft. Rotation of the rockshaft causes the disc opener units to be raised or lowered. When the disc opener units are lowered into a field engagement position, further rotation of the rockshaft will cause compression of down pressure springs for each of the disc opener units.

  • Automatic down pressure adjustment system for set of ganged disc openers
    Patent number: 8275525
    Abstract: A disc opener unit for an agricultural implement has a down pressure adjustment device that automatically adjusts the amount of down pressure applied on a furrowing disc based on strain measurements taken by a strain gauge or load cell. The strain gauge, which may be mounted to an arm that is used to set the position of a depth setting gauge wheel, provides feedback to a processor that in turn controls the amount of hydraulic fluid in a hydraulic cylinder to adjust the down force applied on the disc. The amount of down pressure is therefore adjusted in substantially real-time in response to changes in field conditions, which improves furrow depth consistency and reduces wear on the gauge wheel and its components.

  • Depth Adjustment Assembly For A Disc Opener Of An Agricultural Implement
    Publication number: 20120216731
    Abstract: A disc hub assembly includes a shouldered spindle that is secured to a disc opener frame and to which a depth adjustment arm and a gauge wheel arm are connected. The disc hub, to which a ground opener disc is mounted, is disposed on the spindle in a manner that allows the disc to rotate around the spindle. A gauge wheel is connected to the gauge wheel arm. When the depth adjustment arm is rotated between depth setting positions the gauge wheel arm is also rotated. As the gauge wheel is connected to the gauge wheel arm, rotation of the gauge wheel arm causes rotation of the gauge wheel. The depth adjustment arm is spring biased into engagement with an arc of notches on the disc opener frame. The notches define a range of positions at which the depth adjustment arm may be positioned.

  • Agricultural implement having wheels that caster
    Patent number: 8235133
    Abstract: An agricultural implement includes a hitch boom to which a pair of wing booms is pivotably connected. The wing booms are designed to fold forward from an extended position to a transport position. The wing booms are supported above a surface by wheels that provide the aforementioned support when the wing booms are in an extended position as well as the transport position. Maintaining surface contact of the wheels in both positions reduces the load placed on the hitch to which the hitch boom is coupled as well as the hitch boom itself. Multi-link draft links are connected between the hitch boom and the wing booms to provide support for the wing booms when the wing booms are in the extended position. The relative length of the draft links dictates how far the hitch telescopes when the wing booms are folded to the stowed or transport position.

  • Method and apparatus for controlling the depth of an agricultural work unit mounted to a frame that can be raised and lowered by a cylinder assembly
    Patent number: 8235130
    Abstract: An agricultural implement has a depth control system in which a position sensor directly measures linear translation of a hydraulic cylinder that lifts and lowers the implement frame to set and adjust the depth of the implement frame. The position sensor may be positioned adjacent to or integrally formed with the hydraulic cylinder, and provides a voltage to a controller remote from the implement. The controller automatically adjusts the flow of hydraulic fluid to and from the hydraulic cylinder to maintain the depth of the implement frame at an operator-selected level.

  • Seed boot for double-shoot disc opener
    Patent number: 8215247
    Abstract: A planting unit for depositing fertilizer and seed in a single pass, double shoot manner includes a rotating disc that cuts a furrow in a planting surface and a trailing seed boot, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface. The disc has a mounting frame for mounting the disc to a linkage assembly that is, in turn, coupled to a toolbar mount. The seed boot is also attached to the mounting frame. This common attachment provides a relatively short and compact device without sacrificing fertilizer and seed stratification.
