Abstract: An agricultural implement includes a frame having a pair of tool-carrying wings pivotally mounted thereon for pivotal movement between raised transport positions and lowered ground-working positions. Each wing has a hydraulic wing actuator connected thereto which is extendable and retractible for effecting the pivotal motion. A hydraulic wing actuator circuit is connected to each of the wing actuators, which circuit, when connected to a tractor hydraulic system, enables the wing actuators to apply down pressure to said wings when the wings are in the lowered working positions. A hydraulic pressure control valve system controls the down pressure exerted by the wing actuators.

Abstract: A nurse inductor mechanism for an agricultural seeding implement converts an air seeder meter box into a nurse inductor box to convey seed particles to the singulator of a planting mechanism. The nurse inductor mechanism is detachably mounted on the meter box of the air seeder to receive a supply of seed particles therefrom. The nurse induction mechanism intercepts the normal air flow for the metering mechanism to divert the stream of air into engagement with a pile of seed particles and induce the entrainment of the seed particles for conveyance thereof to the remote planting mechanism. A partition wall divides the nurse induction mechanism into a seed side and an air side. The seed side receives the supply of seed particles from the hopper and allows the seed to pass through a passageway into the air side for engagement by the stream of air.

Abstract: A primer system for agricultural product distribution machines, such as an agricultural air seeder, a precision planter, a sprayer, or the like, includes a tank or a bin for holding the product, a distribution system for conveying and distributing the product from the tank and a driving mechanism for driving the product from the tank into the distribution system at a certain rate. The driving mechanism can run automatically or can be selectively operated, based on commands received from a microcontroller. The microcontroller may receive signals from a user interface and from sensing equipment, such as a ground speed detector, a pressure sensor, a flow metre, or the like. In a regular mode of operation, the controller runs the driving mechanism automatically at a rate calculated based on the signals received from the above mentioned systems. Most agricultural machines have the automated mode of operation of the driving mechanism, conditioned by the ground speed of the tractor being higher than a minimum speed.

Abstract: A nurse receiver header for an agricultural planting implement is cooperable with a nurse mechanism that conveys a stream of seeds entrained in an air stream from a central hopper. A receiver is positioned at the planting mechanism to receive the seeds entrained in the air stream and accumulate a supply of the seeds for utilization by the associated planting mechanism. The receiver header may include a vent for dissipating the air stream when receiving the seeds for distribution to the receiver. The vent is provided with a hood to keep contaminants from entering the vent and passing into the planting mechanism. The receiver header is positioned so that an appropriate supply of seeds for the planting mechanism fills the tube between the receiver header and the receiver including the vent, resulting in a decreased volume of discharged air for the air stream and a diminished ability for the nurse mechanism to convey seeds. The receiver header can be configured to service multiple receivers.

Abstract: A headlands control system for a winged agricultural implement includes a headlands actuator operatively connected between implement wing actuators for establishing operation in either of two modes. In the first mode, when the headland actuator is in a first position (e.g. extended), the wing actuators are provided extra downward range to pivot and bias the wing sections downward below horizontal as may occur during operation over uneven ground. In the second mode, when the headland actuator is in a second position (e.g. retracted) and the implement is raised (e.g. at the headlands), the downward range of the implement wings is more limited (as compared with the first mode) at the point where the wing actuators are fully extended. This system thus provides an apparatus for preventing implement wings from drooping in the headland position so the operator is not required to reset the wing control from float mode, or from down pressure mode, depending on what is equipped.

Abstract: A nurse adapter mechanism for an agricultural seeding implement converts an air seeder meter box into a nurse inductor box to convey seed particles to the singulator of a planting mechanism. The nurse adapter mechanism is detachably mounted on the meter box of the air seeder to receive a supply of seed particles therefrom and utilizes the normal air flow for the metering mechanism to effect a nursing of seed particles to a planting mechanism. The nurse adapter mechanism diverts the stream of air into engagement with a pile of seed particles and induce the entrainment of the seed particles for conveyance thereof to the remote planting mechanism. A partition wall divides the nurse induction mechanism into a seed side and an air side. The seed side receives the supply of seed particles from the hopper and allows the seed to pass through a passageway into the air side for engagement by the stream of air.

Abstract: A ground opener unit for a seeding or planting unit includes an arm attachable to an implement frame and a disc rotatably mounted to the arm for forming a furrow in the ground. A scraper assembly includes a scraper plate defining a scraper edge for contacting and scraping a surface of the disc. The scraper plate defines a mounting region remote from the edge. A scraper plate mount secures the scraper plate adjacent the disc and a resilient pad of material is interposed between the plate mounting region and the scraper plate mount. A spaced pair of fasteners extend through the mounting region to secure the scraper plate and resilient pad to the scraper plate mount. The fasteners are located in selected positions in the mounting region relative to the resilient pad such that the scraper plate is capable of being tilted or rocked when said scraper edge encounters irregularities thus assisting the scraper edge to follow the disc surface during use.

Abstract: A regulator for a nurse inductor mechanism on an agricultural seeding implement controls the rate of entrainment of seeds into the stream of air directed into the nurse inductor mechanism. The regulator includes a pivoted gate mounted at the discharge opening of the seed reservoir of the nurse induction unit to control the flow of seed particles into a pile for engagement with the stream of air directed thereto. An actuation lever, positioned externally of the nurse inductor housing so as to not interfere with the sealed relationship between the divider walls of the distribution apparatus and the housing, is selectively manipulable to move the pivoted gate between closed and opened positions. Once the pivoted gate is moved into the closed position, the flow of seed particles into the distribution apparatus is halted, but the fall flow of air can still move through the distribution apparatus and seed distribution tubes to effect a clean-out of the nurse induction unit.

Abstract: A new and useful meter roller assembly is provided for an agricultural implement for metering material delivery between a meter box and a series of material runs leading to a series of material distributors, the assembly comprising a shaft for mounting for rotation in the box; a series of roller sections for mounting on the shaft, extending across the runs, the roller sections chosen from the group consisting of blank sections or metering sections; and wherein the series of roller sections includes at least one metering sections corresponding to one the run, for securing to the shaft for rotation therewith and comprising at least one fluted segment and at least one blank segment.

Abstract: A connection circuit for connecting a first and an active hydraulic circuit. The first circuit is a fan or motor on an air cart which uses a fixed amount of volume. The active circuit is for applying a down pressure on a pulled, ground--working implement. The connection circuit also has a valve for switching the flow to the active circuit from the first circuit to the tractor hydraulics. In an alternative embodiment, there is an orifice and check valve or pressure relief valve for preventing the active circuit from withdrawing an excess amount of hydraulic flow from the first circuit.
