An agricultural product application system includes a controller and product dispensing apparatus. The product dispensing apparatus includes a metering module in communication with the controller and is configured to control a flow rate of product from a product source to product dispensing units. A display device is in communication with the controller. The controller receives operating limits and an application rate of the product dispensing apparatus. The controller determines a forward speed range based upon the operating limits and on the application rate. Display information is generated for providing a visual representation on the display device of the forward speed range.

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 granular product detection system is provided. The system includes a first sensor or first sensor array configured to couple to an air cart or a fill system that fills a tank of the air cart with a granular product, wherein the first sensor or first sensor array is configured to automatically detect at least a product type of the granular product. The system also includes a controller coupled to the first sensor or first sensor array and configured to receive feedback from the first sensor or first sensor array to automatically determine a control parameter related to a conveyance of the granular product based at least on the product type of the granular product.

A metering system for distributing particulate material includes a meter housing containing a metering wheel. An inlet and/or outlet of the meter housing provides a projection extending into the opening of the inlet and/or outlet so that the flow of particulate material is optimized. This can provide even distribution of such material, including at low rotating speeds such as 5 RPM, while using a polyurethane metering wheel with straight vanes. In one aspect, projections extending into the inlet on opposing sides can substantially form an hourglass shape, and the outlet can comprise a substantially diagonal shape, analogous to a parallelogram, instead of more traditional rounded/rectangular shapes.

A metering system for an agricultural vehicle includes meter rollers, each including protrusions driving flow of flowable particulate material in response to rotation of the meter roller. The metering system also includes a drive shaft driven in rotation and includes transmission assemblies that each correspond to a respective meter roller. Each transmission assembly includes a respective moveable gear actuatable to engage each of a plurality of gears to establish a respective gear ratio corresponding to one of a plurality of different speeds of the respective meter roller relative to the drive shaft.

A particle delivery system of an agricultural row unit includes a particle belt having a particle acceleration section. The particle belt is configured to receive a particle from a particle metering and singulation unit, to accelerate the particle at the particle acceleration section, and to expel the particle toward a trench in soil. The particle delivery system includes a first wheel engaged with the particle belt at a first location and a second wheel engaged with the particle belt at a second location. The particle acceleration section extends between the first location and the second location, a substantially no-slip condition exists between the first wheel and the particle belt at the first location and between the second wheel and the particle belt at the second location, and the second wheel is configured to rotate faster than the first wheel to accelerate the particle at the particle acceleration section.

A planter system for planting seeds and dispensing a fluid includes a seeder assembly including a seed meter configured to dispense a group of seeds through a seed tube, a nozzle assembly configured to dispense the fluid in response to receiving a control signal, and a sensor configured to transmit detection signals upon detection of the first and last seeds passing through the seed tube. The planter system further includes a control system communicatively coupled to the sensor to receive the detection signals from the sensor and identify a trigger time based on the detection time of the first seed, the detection time of the last seed, or a time between the detection times. The control system transmits the control signal to the nozzle assembly based on a number of seeds in the group and the trigger time to apply the fluid on or adjacent the group of seeds.

Various embodiments of a system for automatically sensing and spraying plants and/or plant precursors as they are planted or otherwise distributed on and/or within the ground is disclosed.

An agricultural air cart assembly is provided with individually controlled product distribution lines which allows for balanced pressures and even dispersal of air through different distribution lines of different lengths running to different sections or row units of a seeder or drill. Rotatable fans are operatively connected to corresponding first and second distribution lines and are configured to generate optimized air flows in the first and second distribution lines which entrain and carry the product downstream toward corresponding row units at balances pressures. A controller is operable to adjust the pressures of the air flows outputted by the first and second fans by adjusting the position of corresponding fan shrouds over the intakes of the first and second fans.

A seed meter comprising a seed handler comprising a cylinder comprising a plurality of seed chambers. The seed handler rotates the cylinder to sequentially position each seed chamber in a ‘loading’ position wherein each seed chamber receives a sets of seeds, a ‘planting’ position wherein seeds from each seed set are parsed, and an ‘evacuation’ position wherein any seeds remaining in each chamber are evacuated from each chamber. The seed meter additionally comprises a seed separator comprising a seed disc. The seed disc rotates, parses seed from each seed chamber, and transports the seeds to the exit chute. Importantly, the seed meter is structured and operable to substantially simultaneously, receive the sets of seed in the respective chamber positioned in the ‘loading’ position, parse the seeds from the respective chamber positioned in the ‘planting’ position, and evacuate the remaining seed from the respective chamber positioned in the ‘evacuation’ position.
