A pneumatic valve for an agricultural product distribution system includes a fan inlet, a tank outlet, a shuttle, a control pressure inlet, and a diaphragm. The fan inlet is coupled to an air source that supplies an air stream into a primary line, which facilitates distributing a granular product to an agricultural implement by guiding the air stream from a first section to a second section of the primary line, the first section having a larger cross-sectional area than the second section. A tank outlet is fluidly coupled to a storage tank. The control pressure inlet is fluidly coupled to the second section of the primary line or to a meter housing. The diaphragm has a first side that is coupled to the shuttle and is exposed to static pressure in the storage tank and a second side that is exposed to the static pressure in the second section of the primary line or the meter housing, and aligns a shuttle hole of the shuttle with the fan inlet when the static pressure in the storage tank is not greater than the static pressure in the second section of the primary line or the meter housing by a threshold amount.

A disc-opener implement for use with an agricultural implement includes a disc configured to form a trench in a surface of a field and a scraper adjacent to the disc. The disc-opener implement also includes a knife that is configured to form a furrow next to or into a sidewall of the trench, wherein the knife comprises a leading edge, and a portion of the leading edge is aligned with a trailing edge of the scraper along a lateral axis of the disc-opener implement.

Double-shoot knife attachment

An agricultural metering system includes a releasable bearing coupler configured to selectively couple a meter roller to a housing of the agricultural metering system. The releasable bearing coupler includes a shaft configured to be disposed through an opening in the housing and to engage a bearing, wherein the bearing is configured to be disposed within a recess of the meter roller to facilitate rotation of the meter roller about the shaft and to couple the meter roller to the housing via contact with the shaft. The releasable bearing coupler includes a locking segment configured to selectively interlock with a corresponding locking feature of the housing to secure the releasable bearing coupler to the housing.

In one aspect, a system for controlling an operation of an actuator mounted on a seed planting implement may include an actuator configured to adjust a position of a row unit of the seed planting implement relative to a toolbar of the seed planting implement. The system may also include a flow restrictor fluidly coupled to a fluid chamber of the actuator, with the flow restrictor being configured to reduce a rate at which fluid is permitted to exit the fluid chamber in a manner that provides damping to the row unit. Furthermore, the system may include a valve fluidly coupled to the flow restrictor in a parallel relationship such that the valve is configured to permit the fluid exiting the fluid chamber to flow through the flow restrictor and the fluid entering the fluid chamber to bypass the flow restrictor.

A system includes an agricultural metering system a meter roller configured to meter product from an agricultural product storage compartment to a product distribution system via rotation of the meter roller. The meter roller includes a first meter roller segment having a first plurality of flutes and a corresponding first plurality of recesses, and a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses. The first meter roller segment includes a first profile, the second meter roller includes a second profile, and the first profile is different from the second profile. The system also has a dividing ring axially positioned between the first meter roller segment and the second meter roller segment.

Meter roller and cutoff system

Disc drill agricultural implements are configured to form product rows in a planting surface of a field. The disc drill may include two different sections of row units, the first section containing single-shoot row units and the second section containing double-shoot row units. The configuration may be used to produce three sets of product rows which may be used placement of seeds, fertilizer and/or other agricultural products.

A system includes an agricultural metering system with a meter roller configured to meter product from an agricultural product storage compartment to a product distribution system via rotation of the meter roller. The meter roller includes a first meter roller segment having a first plurality of flutes and corresponding recesses, and a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses. The flutes of the first meter roller segment are axially separated from the flutes of the second meter roller segment by a gap. The meter roller also includes a dividing ring disposed about the shaft and axially positioned between the first meter roller segment and the second meter roller segment. A width of the dividing ring is substantially equal to the gap.

An agricultural metering system includes a driven shaft having a first engagement feature configured to selectively engage a second engagement feature of a drive shaft mounted within a meter box of the agricultural metering system to non-rotatably couple the driven shaft to the drive shaft. The agricultural metering system includes a meter roller non-rotatably coupled to the driven shaft. The meter roller is configured to be selectively disposed within the meter box, and the first engagement feature is configured to engage the second engagement feature while the meter roller is disposed within the meter box to facilitate rotation of the meter roller in response to rotation of the drive shaft.

A product distribution control system for an agricultural system includes a controller having a memory and a processor. The controller is configured to receive a first signal indicative of a prescription map. The controller is further configured to determine a first parameter associated with operation of an air cart of the agricultural system based at least in part on the prescription map. The controller is further configured to determine at least one of a second parameter associated with operation of a work vehicle of the agricultural system based at least in part on the prescription map, and a third parameter associated with an implement of the agricultural system based at least in part on the prescription map, wherein the implement includes one or more row units. The controller is further configured to output, in response to determining the first parameter, a second signal indicative of an instruction to control a first element of the air cart based at least in part on the first parameter, output, in response to determining the second parameter, a third signal indicative of an instruction to control a second element of the work vehicle based at least in part on the second parameter, and output, in response to determining the third parameter, a fourth signal indicative of an instruction to control a third element of the implement based at least in part on the third parameter.

Product distribution control system for an agricultural system

A pneumatic distribution system for distributing a granular product to an agricultural implement includes a first pressure sensor, a second pressure sensor, a valve, and a controller. The first pressure sensor is fluidly coupled to a storage tank that stores the granular product and outputs a first signal indicative of a first static pressure in the storage tank. The second pressure sensor is fluidly coupled to a meter housing and outputs a second signal indicative of a second static pressure in the meter housing. The valve is fluidly coupled between the storage tank and the primary line and selectively enables the air stream to flow from the primary line to the storage tank. The controller is communicatively coupled to the first pressure sensor, to the second pressure sensor, and to the valve. The controller instructs the valve to enable the air stream to flow from the primary line into the storage tank until the first static pressure is greater than the second static pressure by a threshold amount.
