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： 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： The invention provides a system, device and method for using a rotary actuator, e.g., a stepper motor to actuate a wrap spring clutch. Feedback from a system of sensors and GPS data, including rotational speed, travel speed and direction are provided to improve the reaction accuracy of the clutch. In one embodiment, a plurality of actuator controllers are connected in a configuration wherein one controller is a “master” and the remaining controllers are “slaves” to provide a higher level of machine control.

摘要： An agricultural implement such as a planter has wing sections which, when folded for transport, are stacked side-by-side above a center section. Improvements include structure which reduces bending moments about the pivot connections between a guide link forming part of a four-bar linkage which stacks the wings, and the wing frame. A drive train for the row unit meters is also placed in the transport position without disconnecting the drive shafts.

摘要： An agricultural implement, such as a row crop planter, has a main carrier frame drawn by a tractor and including support wheels. Individual row units are mounted on a lift frame. The carrier frame includes a cornered lift post which is mounted for rotation about a vertical axis. A cornered sleeve or collar in the form of a tube is mounted to the lift frame for vertical sliding motion on the lift post. A lift hydraulic cylinder couples the lift frame to the carrier frame for setting the lift frame in (i) a use position wherein the row units are lowered to engage the soil; (ii) an intermediate, raised position wherein the row units are disengaged, for negotiating end turns; or (iii) a fully raised position wherein the lift frame and row units may be rotated from a transverse position to a longitudinal position, to narrow the implement for road travel. A swing hydraulic cylinder is arranged to rotate the lift post when the lift frame is raised to the uppermost position, to torque the lift frame to a longitudinal position for transport.

摘要： An agricultural implement, such as a planter, having a telescoping tongue for placing the implement in either a transport or field use configuration, includes an hydraulic pump located on the planter frame, preferably toward the rear, for powering the planting functions. A mechanical drive line from the PTO of the tractor to the remote hydraulic pump is disengaged as the planter frame begins to move from the planting position. The drive line permits the tractor to make full 90° turns in the field.

摘要： An agricultural seed meter is disclosed including a seed selection mechanism in the form of a belt or a drum having pockets and moving through a seed reservoir area for loading seeds into the pocket. A cut-off brush is movable between a singulating position and a volume metering position so that the meter may be used either as a singulating meter or for volume metering without changing, deleting parts or adding parts. In either mode, seed release is accurate and repeatable through the use of a retainer brush for holding the seeds in their associated pocket until the pocket, in a downward, curving path, passed beyond the end of the retainer brush, thereby releasing the seeds into a discharge conduit.
