A frame is provided with there being first structure on the frame for penetrating the soil to create an opening for at least one of seed and fertilizer as the frame is advanced in a travel direction. A second structure is provided on the frame at least partially downstream of the first structure for at least one of a) stripping soil clods from the first structure and b) loosening soil downstream of the first structure.

A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short drop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture, move and accelerate the seed. By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.

A nurse distribution system provides dual capabilities for planting different seed varieties from a single planting mechanism. The air cart carries two tanks in which different seed varieties can be placed. The nurse mechanism selectively distributes seed from one tank to the on-row singulation meters, yet can switch to the seed in the second tank to correspond to different soil conditions encountered by the planting mechanism. The planting mechanism carries a first line from the first tank to the nurse receiver and a parallel second line from the second tank to the same nurse receiver. By keeping the nurse receiver as small as possible, thus having a small seed reservoir, the seed variety selection can be switched from one tank to the other in an effective manner.

A seed metering assembly for a farm implement has a meter roller that can be accessed and removed in a relatively quick manner. The seed metering assembly includes a fluted meter roller that is segmented into a number of discrete fluted sections. Each fluted section has an associated flow control member that is selectively operable to impede the flow of granular material from a seed hopper to its corresponding section of the fluted meter roller.

(d) delivery means including an adjustable flow venturi (62) and electronic sensor (66) for controlling delivery of metered seeds.

The present invention relates to a steering device for facilitating the steering of an implement towed by a work vehicle. The towed implement, for example, a farm implement such as a seeding device, comprises a main frame having front and rear ends and at least one steerable surface engaging wheel attached to the frame. The steering device comprising a sensor means mounted on the main frame of the towed implement for sensing a misalignment of the towed implement and the work vehicle and producing a signal corresponding to the misalignment. The steering device further comprises a steering means associated with the steerable wheel for receiving the signal produced by the sensor means and for effecting movement of the steerable wheel in response to the signal until the towed implement and the work vehicle are once again realigned.

A seeding machine includes at least one seed metering system and at least one seed placement system. Each seed placement system is in communication with a corresponding seed metering system. Each seed placement system includes a housing having a seed slide, and a wheel at least partly disposed within the housing. The wheel has a circumferential periphery with a plurality of contiguous disc joint surfaces. The periphery is positioned adjacent to at least part of the seed slide. The invention comprises, in another form thereof, a method of placing seeds with a seeding machine in a trench formed in soil. Seeds are received at a predetermined rate at a seed placement system. The seed placement system includes a seed slide, and a wheel having a conferential periphery position closely adjacent to at least part of the seed slide. The seeds are engaged at the predetermined rate against the wheel periphery. The seeds are carried past a closely adjacent area of the seed slide using the wheel periphery. The seeds are released from the wheel periphery.

An air seeder distribution apparatus has seed and fertilizer tanks, and a like plurality of metering devices mounted on each product tank. A manifold set comprises a like plurality of product manifolds and each manifold is separately fed from one metering device on each of the seed and fertilizer tanks. A control selectively starts and stops rotation of the feed roller of each metering device to feed product from either tank, or both tanks to the connected manifold. The weight of each tank can be displayed on a weight indicator. Balancing of the pressure in each supply conduit can be provided. A remote opener exerts downward force on the tank lid to maintain interior pressure.

An agricultural planter includes systems, methods, and apparatus for providing down force pressure at row units of the planter. The row units may include an electric linear actuator connected to linkages of the row units to provide and maintain a down force pressure for the row unit. The linkage may also be removed and replaced with a strut or like mechanism to apply a direct down force pressure to components of the row unit. One or more sensors can be included to obtain information related to the ground to automatically adjust the amount of down force provided based upon a ground characteristic in order to maintain a substantially uniform furrow depth.

A seed delivery system is provided that includes a row crop seed planter having a seed meter that can pneumatically deliver seeds to the agricultural field at a rearward velocity that matches a forward velocity of the planter. The seed meter may include a positive pressure source that pressurizes the seed meter and creates an airflow out of a seed tube of the seed meter that carries the individual seeds out of the seed tube at a rearward velocity that is automatically adjusted to match a forward velocity of the seed planter and tractor.

An agricultural planter having sensors for measuring multiple soil properties adjusts planting depth and seeding rate in real time based on the measured soil properties. An optical module is carried by the planter for collecting soil reflectance data. A pair of soil contact blades protrude from or are embedded in the optical module for collecting soil EC data and soil moisture data. A switching circuit or phase lock loop allows the same soil contact blades to feed signals to both a soil EC signal conditioning circuit and a soil moisture signal conditioning circuit. The soil moisture data can be used to calibrate the soil EC data and the soil reflectance data to compensate for effects of changing soil moisture conditions across a field. The sensor module can be positioned behind a seed tube and used as a seed firmer, or incorporated into a seed tube guard.

An air distribution apparatus has a manifold body, and ports defined through walls thereof, with a delivery conduit connected to each port. A port valve is configured to connect and disconnect the delivery conduit to the interior of the manifold body. A supply conduit delivers a product air stream with agricultural products entrained therein to the interior of the manifold body. The supply conduit extends vertically up from the manifold to a curved elbow and then extends horizontally from the elbow. An exhaust orifice is defined in the inner radius of the elbow. When an exhaust valve is open, a selected flow of pressurized air flows from the supply conduit through the exhaust orifice. The port valve and exhaust valve are controlled such that when the port valve closes, the exhaust valve opens. The exhaust air can be directed into the delivery conduits to clear product therefrom.

An agricultural implement is provided that includes a number of row units. The row units include one or more seed meters for receiving, singulating, and dispensing seed to the ground such that preferred spacing of subsequent seed is attained. Seed delivery systems are included to aid in transporting the seed from the seed meter to the ground in a controlled manner to mitigate skips and to aid in controlling the spacing of the seeds, which can be based upon the ground speed of the implement as it moves through the field. The seed delivery systems can control the transport of the seed to a furrow in the field such that the seed can experience zero or near zero relative velocity so that the seed will have little to no movement once positioned in the furrow.

A seeding machine includes at least one seed metering system and at least one seed placement system. Each seed placement system is in communication with a corresponding seed metering system. Each seed placement system includes a seed slide having a bottom end and a seed trough terminating at the bottom end.
