The present invention provides a method and apparatus to improve seed distribution to a plurality of seed or row units of an agricultural planter. Each row unit is fitted with a seed box having an air/seed inlet and an air outlet through which air is allowed to escape. The present invention effectively closes off or substantially reduces the flow of air out of one or more of the seed boxes to reduce the amount of seed that is fed to the seed boxes. Through the use of restrictor plates, which may be vented to allow some air flow or solid to prevent air flow, the delivery of seed to the seed boxes can be equalized to provide more uniform seed distribution to the row units.

Precision hoe opener

A constraint assembly is provided to support a series of hoses associated with operation of an agricultural implement with a telescoping tongue assembly. The telescoping tongue assembly includes at least one telescoping arm configured to move between an extended and a retracted position in telescoping relation to a fixed tongue arm of the agricultural implement. The constraint assembly generally includes a first linkage and a second linkage. The first linkage includes a first end pivotally connected to the fixed tongue arm. The second linkage includes a first end pivotally connected to a second end of the first linkage. A second end of the second linkage is pivotally connected to the telescoping tongue arm of the telescoping tongue assembly. The constraint assembly is configured to take up the slack generated in flexible lines as the telescoping tongue arm moves between the extended and the retracted position.

Assembly for and method of constraining a flexible line of an agricultural implement

A holder assembly is illustrated to support at least one flexible line extending along a telescoping tongue assembly of an agricultural implement. The holder assembly includes a first pivotally coupled link in general parallel alignment with a second pivotally coupled link, and at least one post pivotally interconnected between the first pivotally coupled link and the second pivotally coupled link. The holder assembly further includes a bracket connected at the post and configured to receive the at least one flexible line between the bracket and the post. As the telescoping tongue assembly moves between a retracted position and an extended position, the holder assembly enhances support of the flexible lines.

Holder assembly

A support assembly is configured to carry a series of flexible lines associated with operation of an agricultural implement. The agricultural implement generally includes a main frame bar pivotal about a platform. The support assembly includes a mounting bracket, a support arm and a holder assembly. The mounting bracket is pivotally coupled about a vertical axis to the agricultural implement. The support arm is pivotally connected at one end to the agricultural implement, and connected at the other end to the holder assembly. The support assembly is configured to hold the plurality of flexible lines above the platform as the main frame bar pivots about the platform of the implement.

Support assembly for a flexible line of an agricultural implement

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. Divider walls are provided to isolate each discharge tube from the other discharges tube so that the planter mechanisms can provide a continuous supply of seed particles. The discharge tubes pass through the nurse induction mechanism in a stacked pair, modular configuration with the respective discharge tubes being adequately separated with respect to the seed side to permit the passage of seed particles therebetween.

Nurse inductor apparatus for air seeders

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.
