A distribution tower comprising an upright conduit for pneumatically conveying particulate material in a primary stream. The tower additionally includes a distribution head at the upper end of the conduit, with the distribution head comprising a plenum chamber for receiving the primary stream of particulate material from the conduit. The distribution head further comprises a plurality of discharge outlets for directing particulate material out of the plenum chamber by splitting the primary stream into a plurality of secondary streams. Each of the secondary streams is discharged from the distribution head via one of the discharge outlets. The tower additionally includes a flow adjustment system configured to adjust a distribution of particulate material between the secondary streams without completely restricting the flow of any of the secondary streams through their respective discharge outlet. The tower further includes a control system for controlling operation of said flow adjustment system.

Seed-flow adjustment system

An agricultural implement broadly includes a ground-engaging tool, a time-of-flight sensor, and a controller. The time-of-flight sensor is configured to obtain information indicative of seed parameters, furrow parameters, and/or soil condition parameters. The controller is configured to process the information obtained by the time-of-flight sensor to generate the parameters, wherein the controller is further configured to automatically control operation of one or more components of the implement based on the parameters.

Agricultural implement with vision sensors

An autonomous agricultural system comprising an implement configured to perform an agricultural operation. The system additionally comprises an autonomous power unit for autonomously propelling the implement. The system further comprises a coupling assembly configured to connect the implement to the power unit. The coupling assembly provides at least six degrees of freedom of movement between the implement and the power unit.

Autonomous agricultural system

An autonomous agricultural system comprising a mobile power unit including a frame and a power supply. A position of the power supply is shiftable with respect to the frame of the mobile power unit. The autonomous agricultural system additionally includes an implement releasably secured to the mobile power unit. The mobile power unit is configured to transport the implement. The mobile power unit is further configured to provide power from the power supply to the implement.

A ground opener for an agricultural implement. The ground opener comprising an opening disc, and a support assembly securing the opening disc to the agricultural implement. The support assembly comprises an upper bar, a lower bar, a forward bar, and a rearward bar. At least a portion of each of the bars is orientated at an offset angle with respect to a direction of travel of the agricultural implement.

Ground opener with skewed support assembly

A depth-adjustment assembly for ground openers of an agricultural implement. The ground openers each include an opening disc, a gauge wheel, and a support assembly securing the ground opener to the agricultural implement. The support assembly is configured to raise and lower the ground opener with respect to the ground and/or to adjust a down-pressure of the ground opener. The depth-adjustment assembly comprises for each of the ground openers, a linkage assembly and a depth-adjustment arm configured to adjust a relative position between the opening disc and the gauge wheel. At least a portion of the linkage extends in parallel relationship with the support assembly. The depth-adjustment assembly further comprises a laterally-extending common pivot bar. Each linkage assembly is secured to the common pivot bar, such that rotation of said common pivot bar is configured to simultaneously adjust the relative position between the opening disc and the gauge wheel of each of the ground openers.

Ground openers with common depth-adjustment

A control system for a tillage implement broadly includes front and rear sensors, a leveling assembly, and a controller. The front sensor is positioned on a front of a central section, wherein the front sensor is configured to obtain height information indicative of a height of the front of the central section above a ground. The rear sensor is positioned on a rear of the central section, wherein the rear sensor is configured to obtain height information indicative of a height of the rear of the central section above the ground. The leveling assembly is configured to adjust a front to rear orientation of the central section. The controller is configured to receive the height information from the front sensor and the height information from the rear sensor, and to provide instructions to the leveling assembly to adjust the front to rear orientation of the central section based on the received height information.

Tillage implement with vision sensors

A ground-opening apparatus for an agricultural implement. The ground-opening apparatus comprises an opening disc for excavating a furrow in the ground, and a support assembly securing the opening disc to the agricultural implement. The support assembly comprises an upper bar, a lower bar, a forward bar, and a rearward bar. The upper bar and the lower bar extend generally in parallel relationship. The lower bar and the rearward bar are joined at a lower, rearward joint. A rotational axis of the opening disc extends through the lower, rearward joint of the support assembly.

Ground opener with floating opener body

A metering device for dispensing agricultural product from a bin. The metering device comprises a housing enclosing an interior space, and a metering assembly removably received within the interior space of the housing. The metering assembly is configured to convey agricultural product through the metering device. The metering assembly comprises a rotatable sub-shaft, a first metering wheel positioned on the sub-shaft and configured to rotate with the sub-shaft, a second metering wheel positioned on the sub-shaft and configured to rotate with the sub-shaft, and a dividing element positioned on the sub-shaft between the first metering wheel and the second metering wheel.

Metering device with removable metering assembly

A seed meter comprising a housing including one or more air inlets for receiving pressurized air into the housing. The seed meter additionally includes a first metering disc and a second metering disc, each rotatably received in the housing. Each of the first and second metering discs comprises seed pockets for receiving seeds therein.

Dual-seed metering device, system, and method of use

Systems for mounting a plurality of agricultural tools on a transverse support bar and a method for operating an agricultural implement having a transverse support bar. The systems include a lateral positioning structure that can attach to the transverse support bar and a detachable base that can be releasably coupled to the lateral positioning structure.

Agricultural implement tool support system

A seed furrow closing wheel has a generally dish-shaped body defined by a central portion and a notched outer flange portion that circumscribes the central portion and projects obliquely outwardly from the plane thereof. The notched flange portion is configured to present a series of circumferentially spaced, non-radial, obliquely projecting teeth that function to fragment and squeeze together opposite sidewalls of the seed furrow when a pair of the wheels are rolled along opposite sides of the furrow outboard of the furrow itself, crumbling the sidewalls and covering the seeds.
