An agricultural planting system for controlling the depth of an opener device comprising: an agricultural planter; an opener device mounted on the agricultural planter for engaging the ground of a field; a gauge wheel mounted on the agricultural planter for rotating on the ground of the field; a GPS device coupled to the agricultural planter, the GPS device configured to determine a location of the agricultural planter in the field; and a controller in electrical communication with the agricultural planter and the GPS device, the controller having predetermined settings associated with a map of the field, the controller being configured to select a relative elevation of the opener device and the gauge wheel based at least in part on the location determined by the GPS device, and produce, based on the location, a signal for adjusting the depth of engagement into the ground of the opener device.

An agricultural implement system includes a down force cylinder configured to apply a downward force to a row unit, and a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit. The agricultural implement system also includes a valve assembly in fluid communication with the down force cylinder and the depth control cylinder. The valve assembly is configured to automatically adjust the downward force by varying fluid pressure within the down force cylinder based on fluid pressure within the depth control cylinder.

Work machines, fertilizer opener assemblies for work machines, and methods of operating work machines are disclosed herein. A work machine includes a chassis, a frame, and a fertilizer opener assembly. The frame is coupled to the chassis for movement relative thereto. The fertilizer opener assembly is coupled to the frame to selectively form trenches in the soil for the deposition of fertilizer. The fertilizer opener assembly includes an actuator that is extendable and retractable to vary a length of the actuator and a cutting implement coupled to the actuator. Operation of the actuator drives movement of the cutting implement between a cutting position, in which the cutting implement makes contact with the soil to form trenches therein, and a transport position, in which the cutting implement is raised above the soil.

A particle delivery system of an agricultural row unit includes a shuttle track configured to be disposed adjacent to a particle metering and singulation unit, shuttles movably disposed along the shuttle track, and a track belt disposed inwardly of the shuttle track. Each shuttle is configured to receive a particle from the particle metering and singulation unit at a particle reception section of the shuttle track and release the particle toward a trench in soil at a particle deposition section of the shuttle track. The track belt includes paddles, and each paddle is configured to move a respective shuttle along a particle transfer section of the shuttle track from the particle reception section to the particle deposition section.

An agricultural planting implement includes a first wing toolbar configured to support a first set of row units and a second wing toolbar configured to support a second set of row units. The agricultural planting implement also includes a connection assembly having at least one arm pivotally coupling the second wing toolbar to the first wing toolbar. The at least one arm is pivotally coupled to the first wing toolbar and non-pivotally coupled to the second wing toolbar. In addition, the connection assembly includes an actuator configured to drive the second wing toolbar to rotate upwardly relative to the first wing toolbar from a working position to a transport position. The actuator is also configured to urge the second wing toolbar downwardly toward a soil surface while the second wing toolbar is in the working position.

The present invention refers to a new adjustment system for mounting and fixing the supports of the planting row units on the toolbars of agricultural implements, which is designed to eliminate possible gaps realized during the assembly and fixing the planting row units on the toolbar. More particularly, the adjustment system is applied to the mounting guides (20a) of the toolbar (20) and is formed by at least one upper mounting assembly (26) and at least one lower mounting assembly (28), which comprise upper (30) and lower (32) support blocks that are associated with said support (24) by fasteners (34), at least one of said support blocks (30, 32) having at least one opening (36) for accommodating an eccentric bushing (38) whose the passing hole (38a) is displaced from the center of said bushing (38).

Speed control of machines and associated implements during transitions of agricultural parameters is described herein. In one embodiment, a processing system comprises processing logic to execute instructions for processing agricultural data and performing speed control of a machine and associated implement during a transition period for adjusting a setting of an agricultural parameter. A communication unit is coupled to the processing logic. The communication unit to transmit and receive data from the implement. The processing logic is configured to execute instructions to adjust the setting of the agricultural parameter and to determine a desired speed control during the transition period based on at least one of a desired transition distance and productivity during the transition period.

A soil apparatus is drawn through a furrow and reflectance from the furrow is obtained from the soil apparatus, and a height off target is measured between the soil apparatus and the furrow.

A particle delivery system of an agricultural row unit includes a particle belt configured to be disposed apart from a particle metering and singulation unit and a particle acceleration system configured to apply a force to a particle to accelerate the particle from the particle metering and singulation unit and to guide the particle toward the particle belt. The particle belt is configured to receive the particle accelerated from the particle metering and singulation unit, and the particle acceleration system is configured to apply the force to the particle to accelerate the particle from the particle metering and singulation unit to the particle belt, such that a particle speed of the particle reaches a target particle speed, is within a target percentage of a belt speed of the particle belt, or both, as the particle reaches the particle belt.

An agricultural row unit includes a knife disposed ahead of the gauge wheel for delivering material to soil adjacent to a trench. In one example, an agricultural toolbar includes a frame, a wheel mounted to the frame, and a knife disposed ahead of the wheel and comprising a material delivery conduit disposed on, through, or adjacent the knife.
