    摘要： A seed metering system includes a first metering member having a first bearing surface and a second metering member having a plurality of seed engaging surfaces adapted to engage seeds and a second bearing surface positioned against the first bearing surface. The second metering member moves relative to the first metering member. At least one depression extends into the second bearing surface opposite the first bearing surface.

    摘要： A seed tube for an agricultural implement having a seed metering mechanism for uniformly dispensing seeds. The seed tube defines an enclosed curvilinear seed passageway extending between opposite ends of the tube. To promote control over the seeds gravitationally passing through the tube, the seed passageway has a smooth but decreasing cross-sectional configuration between ingress and egress ends of the passageway. The interior surface of the passageway and preferably the tube itself is formed from a material having a coefficient of surface friction ranging between about 0.02 and about 0.10. The enclosed seed passageway furthermore includes a narrowed front edge extending upwardly from a lower end of, the tube and for a majority of the length of the passageway. The narrowed front edge passes beneath and across, in a fore-and-aft direction, the entire ingress end of the passageway for enhancing control over and such that the individual seeds passing through the passageway have substantially equivalent time therein thus promoting equidistant spacings between seed plantings.

    摘要： A method and apparatus for baling a crop with stiff stalks such as corn stalks has a frame with a front and a rear. At least one ground engaging wheel operatively attached to the frame for facilitating movement of the frame in a forward direction. An accumulator is operatively attached to the frame for holding the crop in various amounts. A pickup is operatively attached to the front of the frame for picking up the crop from a field and transferring the crop into the accumulator. A baler is operatively attached to the frame behind the accumulator for transforming a crop into a bale. A transfer mechanism such as a conveyor is provided in the accumulator for moving the crop in the accumulator to the inlet of the baler. In another embodiment, a pickup of a first predetermined width is provided for picking up the crop from a field and transferring the crop into the accumulator. The baler has an inlet and a baling chamber of a second predetermined width that is significantly larger than the first predetermined width of the pickup so that a larger bale can be made. The transfer mechanism can be in segments which are independently operable.

    摘要： An air seed meter having a rotating disc with seed openings arranged in a circumferential pattern includes a holder adapted to be mounted to the meter housing and carries two balls spring-biased to reciprocate and enter the seed openings as they pass and clear debris from the openings. The balls may also engage dimples on the seed disc located between seed openings or groups of seed openings (in the case of a hill drop planter) in the disc as it rotates to cause vibration in the disc to promote the release of seeds as they exit the vacuum chamber.

    摘要： An air seed meter for an agricultural planter includes a vacuum cover which has a central opening which exposes the central portion of the seed disc to the exterior. The central opening of the vacuum cover is centered on a location offset from the axis of rotation of the seed disc. This reduces disc wear at the disc-vacuum cover interface, and renders the disc more accessible for self-cleaning, visual inspection and verification of the proper disc. Openings in the central, open portion of the disc, the back wall of the seed housing and the side wall of the seed housing cooperate to equalize the air pressure in the seed reservoir to atmospheric pressure and reduce or eliminate reverse air currents in the discharge chute. An adjustable brush with three separate stations cooperates with an edge-release, beveled disc to apply a progressively more forceful singulation force to eliminate duplicate seeds.

    摘要： A hopper and lid system for an implement includes a hopper having a bottom and a plurality of walls forming an internal volume with a first opening through which the internal volume is filled and a second opening through which the internal volume is emptied, a lid configured to cover the opening, a first hook coupled to the lid and configured to engage one of the plurality of walls to support the lid relative to the hopper with the opening uncovered and a second hook coupled to the lid and configured to engage one of the plurality of walls to support the lid relative to the hopper with the opening uncovered. The second hook extends obliquely to the first hook. Preferably, the second hook extends perpendicular to the first hook to enable the lid to be coupled to perpendicular walls of the hopper. The hopper and lid system further includes a flexible tether having a first end coupled to the hopper and a second end coupled to the lid.
