A work vehicle with a metering system, airflow system, and a covering structure moveable between various positions for user access includes features that facilitate assembly and/or disassembly of the metering system. The work vehicle has a venturi structure with a plurality of venturi tubes that are disposed in a compact arrangement.

A monitoring system and a monitoring method for a planter includes a computer having an unit speed fusion module, a seeding flow rate monitoring module, and a decision module for theoretical rotation speed of a drive motor, a rotation speed deviation inference module, a controlling parameter tuning module, an adjusting module for rotation speed of a seeding shaft, a controlling module for rotation speed of seeding shaft and a positioning signal receiver fixed on a top of a cab for receiving a geographic position signal. The system monitors operating state parameters of the planter and accurately controls seed amount.

A purging system for a multiple variety seed meter of a multi-variety planter. The purging system includes seed return valves that may be arranged for receiving seed that was removed from the seed meter. The seed return valves return the removed seed into corresponding appropriate seed storage compartments to allow a new seed variety to be delivered to the seed meter while reducing seed variety mixing in the seed meter. A pipe with a purge passage may extend from the seed meter to a purging hose that delivers the removed seed to the seed return valve(s). Each seed return valve may be a vacuum-actuated piston airlock valve assembly with a valve plunger that reciprocates to define seed collecting and releasing states of the valve.

An air cart for use in an agricultural air seeding system includes a first storage compartment for holding a first granular product type. The air cart also includes a second storage compartment for holding a second granular product type different from the first granular product type. The air cart further includes a common conduit configured to receive the first granular product type from the first storage compartment and the second granular product type from the second storage compartment to enable simultaneous flow of the first granular product type and the second granular product type. The air cart even further includes a multi-product particle flow rate sensing system configured to monitor respective flow rates for both the first granular product type and the second granular product type during simultaneous flow of the first granular product type and the second granular product type through the common conduit.

A particulate material metering system includes a controller configured to determine a radius of curvature of a path of a lead vehicle coupled to an agricultural implement. The controller is configured to determine a lead time of the lead vehicle relative to the agricultural implement based on a speed of the lead vehicle and/or the agricultural implement. The controller is configured to determine a radius of curvature of a path of the agricultural implement based on the radius of curvature of the path of the lead vehicle at a determination time, in which the determination time is a current time minus an offset time, and the offset time is based on the lead time. The controller is configured to determine target particulate material flow rates of respective metering devices of the particulate material metering system based on the radius of curvature of the path of the agricultural implement.

A singulating meter includes a seed disc with seed apertures rotates in a vertical plane through a seed reservoir. A horizontal seed tube has an inlet adjacent to the top of the seed disc and the seed apertures move along a seed aperture path toward the inlet. Pressurized air flows into the tube inlet, and through each seed aperture as it rotates upward out of the seed reservoir pushing a seed into each seed aperture which seed then moves along the seed aperture path through about 180 degrees of rotation to a release position at the top of the path where the seed is carried horizontally into the seed tube. An ejector pushes debris out of the seed apertures into the seed tube. An alignment guide moves the singulator element of the meter into the operating position where same is magnetically secured.

An agricultural planting or seeding implement having a ground engaging tool that forms an opening along an axis in the soil, a sensor disposed aft of the ground engaging tool, and a row unit disposed aft of both the ground engaging tool and the sensor relative to a direction of travel of the agricultural planting or seeding implement. The sensor engages with the ground at a depth within the opening and generates a signal indicative of a soil property of the ground.

A system and method for regulating dispensation of seeds, fertilizer or other items. The system comprises a hopper, at least first and second movable metering plates, and an agitator assembly. Movement of the first and second movable metering plates in first and second directions, respectively, that are opposite one another increases a size of a plurality of output holes defined by interleaved portions of the metering plates, whereas movement of the first and second movable metering plates in the second and first directions, respectively, decreases the size of the output holes. An adjustable control handle can be moved to simultaneously move the first and second movable metering plates to adjust the size of the output holes. Each agitator remains in alignment with a center of a respective output hole regardless of a decrease or increase in the size of the output holes, resulting in more efficient dispensation.

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 plurality of different controllers on an agricultural machine are time synchronized. A first controller, identifies an action to be taken based upon a location of the agricultural machine and a speed of the agricultural machine, and also based on a geographic location of where the action is to be taken, and generates a timestamp indicating a time at which the action is to be taken. An action identifier and the timestamp are sent to an actuator controller that controls an actuator to take the action. The actuator controller identifies an actuator delay corresponding to the actuator and controls the actuator to take the action at a time identified in the timestamp based upon the actuator delay.
