A dynamic supplemental downforce control system for a planter row unit. The system includes closed-loop feedback circuit that cooperates with a downforce actuator to dynamically control fluid flow to the downforce actuator to maintain balance between the actual gauge wheel downforce and a desired gauge wheel downforce during planting operations.

A yaw rate is sensed on a towing vehicle that is towing an air seeder. The sensed yaw rate is used to predict a future yaw rate on a planting implement of the air seeder. An application rate of material is varied across the application implement based upon the predicted yaw rate across the implement.

A down-pressure system for an agricultural implement has a linear actuator connected between a frame assembly and an opener assembly. A mounting structure for connecting the linear actuator to the opener assembly includes a bushing and an alignment member attached to the linear actuator. The bushing has protrusions extending transversely from opposite sides of a longitudinal axis of the linear actuator. Each protrusion has a curved engagement surface for engaging a flat surface on the opener assembly to prevent bending stresses on the linear actuator when the opener assembly is raised and lowered. The alignment member is arranged to lock the bushing into a predetermined rotational position about a longitudinal axis of the linear actuator relative to the opener assembly. The alignment member comprises a first structure that mates with a corresponding structure on the bushing, and a second structure that engages opposite sides of the opener assembly.

The present invention provides an agricultural delivery system which may selectively deliver agricultural product (e.g., seeds or fertilizer) along one or more paths to row units according to a real-time location determined for the delivery system. The delivery system may include: a rotating drum configured to separate individual product for depositing along paths to row units; a sectional control system which may include wheels or gates for selectively cutting off product in the paths; and a controller in communication with a positioning system and the sectional control system. In operation, as the delivery system moves through a field, the controller may continuously determine a location for the delivery system. The controller may then operate to adjust individual product delivery, via the sectional control system, according to the location.
