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.

The invention relates to a distributor (10) for granular material, having a distributor head (14), which is designed to divide up an air-material main flow supplied through a main conveying line (12) to the distributor head (14) into a plurality of air-material individual flows, and at least one return device (16), which comprises a movable deflecting element (36), which is designed, in a delivery position, to supply an air-material individual flow flowing into an inflow region (26) of the return device (16) to a delivery region (28), connected to a delivery line (18), of the return device (16) and, in a shut-off position, to direct an air-material individual flow flowing into the inflow region (26) of the return device (16) via a return line (30) of the return device (16) to a return region (32), connected to the main conveying line (12), of the return device (16).

Described herein are methods and systems for generating shared collaborative maps for planting or harvesting operations. A method of generating a collaborative shared map between machines includes generating a first map for a first machine based on a first set of data and generating a second map for a second machine based on a second set of data. The method further includes generating at least one shared collaborative map for at least one of the first and second machines based on the first and second maps.

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.

In one aspect, a system for controlling the operation of a seed-planting implement may include a furrow-forming tool configured to form a furrow in soil present within a field. Furthermore, the system may include a sensor configured to capture data indicative of a topographical profile of the soil within the field. Additionally, a controller of the disclosed system may be configured to identify a topographical feature within the field based on the data received from the sensor. Furthermore, the controller may be configured to determine a position of the furrow-forming tool relative to the identified topographical feature. Additionally, the controller may be configured to initiate a control action to adjust the position of the furrow-forming tool when it is determined that the relative position between the furrow-forming tool and the identified topographical feature is offset from a predetermined positional relationship defined for the furrow-forming tool.

A seed planter assembly for planting seeds in rows throughout a field includes at least one tank for storing the seeds and a seed hose in communication with the at least one tank for delivering the seeds to the field. The seed planter assembly also includes a support frame for supporting the at least one tank and the seed hose, and a linkage assembly (e.g., including a four-bar linkage) coupled with the support frame and the at least one tank. The linkage assembly is configured for lifting the at least one tank from a first orientation proximate to a support surface to a second orientation spaced farther apart from the support surface. The seed planter assembly can also include an actuator (e.g., a hydraulic actuator) connected between the support frame and the linkage assembly for moving the at least one tank between the first orientation and the second orientation.

A product distribution system mounting assembly includes a first member configured to rigidly couple to a frame of an agricultural apparatus and a second member configured to rigidly couple to a plurality of tubular components of a product distribution system of the agricultural apparatus. The first member and the second member are configured to engage with one another to form a sliding interface that enables the plurality of tubular components to move along a vertical axis relative to the frame as the agricultural apparatus moves in a direction of travel through a field.

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.
