Abstract

The agricultural planter includes an open modular fertilizer assembly mounted upon a docking station, independently of the row unit. The fertilizer assembly on the row cleaner can be raised and lowered between the field and transport positions independently of raising and lowering the row unit. The cleaner floats so as to follow the contour of the ground. The fertilizer assembly applies fertilizer on both sides of the seedbed formed by the opening discs to a depth below the seed. The docking station isolates the row cleaner and fertilizer assembly from the planter unit for independent height control of the row cleaner and fertilizer assembly.

Abstract

An agricultural toolbar has a center section and opposite wings which are horizontally foldable between transport and field positions. The toolbar has a hydraulic system which is very adaptable to many different hydraulically controlled features and options, without sacrificing the primary purpose of the system, which is accurately controlling the operating height of the toolbar, to achieve optimal planting depth of modern precision seed and fertilizer application systems.

Abstract

A lift assembly includes an insert frame between the toolbar and a row unit on agricultural planter. The lift assembly frame includes an actuator which is extended and retracted to raise and lower a pair of arms engaging a crop shaft connected to the parallel link arms of the row unit, to thereby raise and lower the row unit between planting and non-planting positions. With one of the lift assemblies associated with each row unit, the row units can be selectively raised and lowered for varied planting operations.

Abstract

A hydraulic height control system controls all raising, lowering and folding movement of agricultural tillage equipment. The system includes a single hydraulic circuit utilizing non-rephase cylinders which allows for independent raising and lowering of the equipment frame sections and tool gangs. The hydraulic circuit also controls the folding of the frame wings between field and transport positions. Sensors monitor component positions. The hydraulic circuit also uses a common rail for providing fluid to the cylinders. The system achieves precise depth control in the high speed tilling agricultural environment by keeping the tilling components at the appropriate depth or operating position

Abstract

A sensor system on the closing wheels of an agricultural planter detects rotational speed of the closing wheels, and generates a signal corresponding to the rotational speed. If the speed is below an optimum or preset speed, the operator is notified that the wheels are not rotating properly or have stopped rotating, thereby indicating improper closing of the seed furrow after the seed is planted in the furrow. A sensor system provides a method of monitoring the function of the closing wheels and generating a signal corresponding to the rotational status of the closing wheels.

Abstract

A seed planter is provided with a plurality of single or paired discs with each pair adapted to form furrows to receive seeds. Each disc is provided with a sensor to detect rotational speed of the disc. Each sensor transmits a signal corresponding to the rotational speed of the disc to a tow vehicle having a control system which compares the disc rotational speed to the tow vehicle travel speed. If the disc rotational speed drops below a predetermined value relative to the vehicle speed, this is indicative of disc plugging and/or furrow smearing, both of which are undesirable, such that corrective action can be taken by the operator of the vehicle or an autonomous vehicle.

Abstract

A seed distributor evenly delivers seed from a bulk seed tank via hoses to seed bins on row planter units. The distributor has a circular chamber for receiving seeds from the seed tank. An internal cone in the distributor deposits the seeds 360° around the chamber. Seed tubes extend through the sidewall of the chamber. Pressurized air is introduced into the chamber and picks up seeds on the floor of the chamber and pass through the seed tubes for delivery by the hoses to the bins. The distributor may also include air tubes aligned with the seed tubes to further assure even distribution of seeds to the bins.

Abstract

A row planter having a pair of gauge wheels mounted on gauge wheel arms includes a controller for adjusting the position of the gauge wheels, and thereby adjusting the planting depth of seeds. The controller is pivotally mounted on the row unit, with a handle on the upper end and a rocker arm on the lower end engaging the gauge wheel arms. The controller can be pivoted about a transverse horizontal axis by movement of the handle so as to adjust the rocker arms, and thereby the gauge wheels arms for adjusting the seed planting depth. The controller further includes a pivotal block to which the rocker arm is mounted. The pivotal block can be adjusted via bolts on opposite forward and rearward sides of the block, so as to fine-tune the rocker arm position, and thereby further adjust the planting depth of the row unit.

Abstract

A closing wheel assembly is provided for a seed row planter unit behind the gauge wheel assembly and furrow disks of the planter unit. The closing wheel assembly includes a coupler with a pair of closing wheels mounted thereon. A single pin removably extends through the coupler and through the gauge wheel assembly to detachably mount the closing wheel assembly to the gauge wheel assembly. Different closing wheel assemblies can be quickly mounted on the row unit, depending upon the type of seed being planted. The closing wheels are laterally adjustable via a rotatable threaded bushing so as to be centered behind the furrow disks.

Abstract

Tapered bearings are used on each end of each link arm on an agricultural seed row planter mounted on a toolbar. The bearing is a low friction material and greaseless. The tapered design of the bearings allows the bearings to be adjusted as wear occurs, by tightening the link arm mounting nut which extends through the tapered bearing. The tapered bearing has an increased life and reduced maintenance, as compared to prior art roller bearings.

Abstract

A closing wheel assembly is provided for a seed row planter unit (10) behind the gauge wheel (19) assembly and furrow disks (17) of the planter unit. The closing wheel assembly includes a coupler (18) with a pair of closing wheels (20) mounted thereon. A single pin (38) removably extends through the coupler and through the gauge wheel assembly to detachably mount the closing wheel assembly to the gauge wheel assembly. Different closing wheel assemblies can be quickly mounted on the row unit, depending upon the type of seed being planted. The closing wheels (20) are laterally adjustable via a rotatable threaded bushing (52) so as to be centered behind the furrow disks (17).

Abstract

The latch assembly for the wings of a folding tool bar includes catches on each wing wing and a pair of pivotal latch arms on the tool bar tongue. An actuator pivots the latch arms between an unlatched position disengaged from the wing catches to a latched position engaging the wing catches so as to retain the wings in a transport position. In the latching and unlatching method, the latch arms are pivoted simultaneously in opposite directions by an actuator to capture and release the opposing wings of the tool bar.

Abstract

A pneumatic manifold is provided for a folding toolbar for use with seed planters having pneumatic seed metering devices. The manifold is formed within the tubular center section and opposite folding wings of the toolbar. A flexible coupler is provided at each wing hinge juncture to provide air flow through the toolbar wings and the center section, while allowing the toolbar to fold and unfold between the transport and field positions.

Abstract

A trailer for transporting an agricultural harvesting head includes a pair of saddles for supporting the head. The saddles are adjustably mounted on the trailer frame and are simultaneously moved together by an actuator operated by a remote control. The saddles are connected by telescoping rod sections so that the spacing between the saddles is adjustable.
