A trailing assembly for an agricultural planter is attached to a frame element of the agricultural planter with a mounting bracket. A walking beam having a hub at an intermediate position along a length of the walking beam is pivotably attached to the mounting bracket. A first pair of arms extends from the hub in a first direction, with each arm configured with a shaft to rotatably and selectively receive a first rotating implement, for example, a closing wheel or a fertilizer opener disc. A second pair of arms extends from the hub in a second direction parallel to each other and spaced apart from each other. Distal ends of the second pair of arms are configured to rotatably and selectively receive and support opposing ends of an axle of another rotating implement, for example, a press wheel, positioned between the second set of arms.

A method of controlling a mobile agricultural machine, the method comprising operating a row unit having a ground-engaging element to deliver product to a furrow formed by the row unit, receiving an indication of rotational speed of the ground-engaging element, determining that the rotational speed of the ground-engaging element is below a threshold, and controlling an action of the mobile agricultural machine based on the determination.

A furrow closing assembly includes a mounting bracket attachable to a planter opener frame, a rigid closer frame, and a four bar parallel linkage connecting the mounting bracket and the closer frame with a first pivot bearing and a third pivot bearing on the mounting bracket and a second pivot bearing and a fourth pivot on the closer frame. A screw-driven linear actuator extends between the parallel linkage to the closer frame. A shaft of the linear actuator is pivotably attached to a torsion axle that is further fixed to an upper portion of the parallel linkage. A load cell is positioned between the linear actuator and the closer frame.

A flow control insert for an agricultural metering system includes a body configured to couple the flow control insert to a housing of the agricultural metering system. The flow control insert also includes a shoulder extending from the body. The shoulder is configured to engage a channel in a meter roller to control flow of particulate material within the channel along a rotational direction of the meter roller.

A trench closing assembly including a scraper.

A trench closing assembly including at least one rock guard.

In one aspect, a system for monitoring soil composition within a field using an agricultural machine may include a ground-engaging tool configured to rotate relative to soil within a field as the agricultural machine is moved across the field. The ground-engaging tool may, in turn, include a tooth defining a cavity therein, with the cavity including an opening. Furthermore, the system may include a sensor positioned within the cavity, with the sensor configured emit an output signal through the opening for reflection off of the soil within the field. The sensor may also be configured to detect the reflected output signal as a return signal, with a parameter of the return signal being indicative of a soil composition of the soil within the field.

A row unit of a seeder includes a frame configured to be coupled to a toolbar of the seeder. The row unit also includes a single opener disc rotatably coupled to the frame and a closing system. The closing system includes a closing disc arm pivotally coupled to the frame, and a closing disc rotatably coupled to the closing disc arm. The closing system also includes a closing disc actuator coupled to the closing disc arm. Furthermore, the closing system includes a packer wheel arm pivotally coupled to the frame. The packer wheel arm and the closing disc arm are configured to rotate independently of one another relative to the frame. The closing system also includes a packer wheel rotatably coupled to the packer wheel arm. Furthermore, the closing system includes a packer wheel actuator coupled to the frame and to the packer wheel arm.

A trench closing assembly having an actuator for applying a force to the trench closing assembly in which the force is divided between closing wheels and a press wheel disposed rearward of the closing wheels.

An agricultural implement includes at least one row unit having a plurality of support members, each of which is pivotably coupled to an attachment frame or another of the support members to permit vertical pivoting vertical movement of the support members, and a plurality of soil-engaging tools, each of which is coupled to at least one of the support members. A plurality of hydraulic cylinders are coupled to the support members for urging the support members downwardly toward the soil. A plurality of controllable pressure control valves are coupled to the hydraulic cylinders for controlling the pressure of hydraulic fluid supplied to the cylinders. A plurality of sensors produce electrical signals corresponding to predetermined conditions, and a controller is coupled to the sensor and the controllable pressure control valves. The controller receives the electrical signals from the sensors and produces control signals for controlling the pressure control valves.
