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 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.

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 soil beating apparatus comprising: (i) a frame configured to he detachably mounted to a support structure of a moveable gantry., (ii) an exhaust hood disposed in combination with the frame and having a shield directing heat downwardly toward a soil material to be heat treated, (iii) a plurality of plates each an end portion projecting downwardly from the exhaust hood toward the soil material and configured to be lowered into the soil material by the frame at a predefined depth relative to the ground plane of the soil material, and (iv) a burner disposed in combination with the exhaust hood and in fluid communication with a first supply of fuel and oxidizer, the burner configured to combust the first supply of fuel and oxidizer to beat each of the plates. The plurality of plates are oriented along a direction of motion of the moveable gantry to transfer heat into the soil material at the predefined depth to thermally heat-treat the soil material.

An adjustable frame assembly of a planter includes a main frame, a first frame member movably coupled to the main frame, and a drive mechanism operably coupled between the main frame and the first frame member for moving the first frame member along the first axis relative to the main frame. The first frame member is laterally movable along a first axis which is perpendicular to a direction of travel of the planter. The frame assembly also includes a first arm having a first end and a second end, the first end being coupled to the main frame and the second end being coupled to a first row unit. A second arm is provided having a first end and a second end, where the first end is coupled to the first frame member and the second end is coupled to the first row unit.

A method of maintaining a desired seed population rate during periods of acceleration of the agricultural planter. In one method, if the horizontal acceleration of the planter is greater than a predefined upper threshold, the seed disc is driven at a rotational speed to maintain the desired seed population rate based on a highest stable ground speed. In another method, if the horizontal acceleration is less than a predefined lower acceleration threshold, the seed disc is driven at a rotational speed to maintain the desired seed population rate based on a lowest stable ground speed. In another method, if the horizontal acceleration is less than the predefined upper acceleration threshold and is greater than the predefined lower acceleration threshold, the seed disc is driven at a rotational speed to maintain the desired seed population rate based on an a preferred planter ground speed input.

A particle delivery system of an agricultural row unit includes a first particle disc configured to meter particles and a second particle disc configured to receive the particles from the first particle disc and to transfer the particles toward a trench in soil. The particle delivery system includes a vacuum source configured to reduce air pressure within a first vacuum passage to couple the particles to one or more first apertures of the first particle disc. The vacuum source is also configured to reduce air pressure within a second vacuum passage to couple the particles to one or more second apertures of the second particle disc. A rotation rate of the first particle disc is controllable to establish a particle spacing between the particles within the trench. A rotation rate of the second particle disc is controllable to expel the particles at a particle exit speed.
