A particulate material sensing and agitation control system of an agricultural system having a drive system configured to operate an agitating system, and a controller having a memory and a processor. The controller is configured to receive at least one sensor signal indicative of a profile of a particulate material within the agricultural system, and output a control signal to instruct the drive system to operate the agitating system in a selected operating mode of a plurality of operating modes based on the profile of the particulate material. The agitating system is configured to interact with the particulate material in each operating mode of the plurality of operating modes, and the plurality of operating modes includes an agitation mode and a leveling mode.

An air cart for distributing air entrained particulate material from a chamber or tank to a plurality of distribution lines for application to an agricultural field has a tank refilling feature utilizing air flow from the cart distribution system or from a dedicated pneumatic source. The cart conveying system air flow is diverted and passed through an assembly containing multiple venturis which also receives particulate material from a supply source. The air entrained material from the source is conveyed to and gently deposited in the cart tank. Exhaust air from the tank may be directed back into the cart conveying system or vented through an air diffuser located beneath the cart. Exhaust air which is directed back to the cart conveying system may return to a location closely adjacent that from which it was originally diverted.

An arrangement for detection of the amount of material in a supply container of a machine for application of material to a field comprises a data entry device for receiving fill level data concerning an amount of material present in the supply container at a specific time point and an outflow sensor for detection of the amount of material that has flowed out of the supply container. A computer device connected to the data entry device and outflow sensor, the computing device is programmed to calculate the current amount of material in the supply container using the obtained fill level data and the signals of the outflow sensor obtained after the specific time point, and to issue a warning signal if the amount of material in the supply container goes below a predetermined level.

The objective of the present invention is to provide a work vehicle where an operator can, on the work vehicle side, confirm which working machine is engaged and set which working machine to engage. A tractor, to which a working machine can be mounted, is provided with: a liquid crystal panel selectably displaying an engageable working machine mounted and displaying the currently engaged working machine so as to be identifiable; an operation unit (encoder dial, enter button, and command buttons) for carrying out selection and determination operations for the working machine displayed on the liquid crystal panel; and a control device that, when a determination operation is carried out by the operation unit for a desired working machine, disengages the currently engaged working machine, and configures the working machine for which the determination operation has been carried out to be engaged.

An environment information collecting system collects environment information on a surface of the earth or a surface layer of the earth. The environment information collecting system includes a sensor element which is scattered in a target region where the environment information is collected, of which at least one of reflection properties, transmission properties, absorption properties, or luminescence properties with respective to an electromagnetic wave with a specific wavelength, or light emitting properties changes in accordance with an environment, and an aircraft configured to receive the electromagnetic wave obtained from the sensor element and configured to collect the environment information in the target region.

A system for replenishing the supply of a particulate agricultural product in the tank of an air cart. A mixture of air and product comes out of a venturi delivery system and enters in a multiplicity of inlet hoses. Then the product enters into inlet tubes of various lengths and release angles from which product particles are gently spread strategically forming a pile that is more or less horizontal to ensure even feeding of meters during dispensing operations. Then the air exits through one or more fine screens to avoid product escaping as well and is conveyed through the exhaust hoses until reaching an air diffuser. The air diffuser has a series of varying size holes or louvers at the bottom so the air can come out at a uniform low velocity which minimizes any discomfort to nearby operators.

The present invention relates to methods and vehicles for separately applying a solid fertilizer and a liquid fertilizer additive to a working area of a field.

A planter system includes a planter having an unloading valve and a controller. The unloading valve is fluidly coupled between an inlet and an outlet of a pump. The unloading valve is configured to receive a fluid at a supply pressure, to supply a first portion of the fluid from the inlet to a hydraulic planter system at an unloading pressure less than the supply pressure, and to recirculate a remainder of the fluid to the pump via the outlet. The controller is communicatively coupled to the unloading valve and to the pump. The controller is configured to control the pressure of the fluid supplied to the inlet and to control the unloading pressure of the first portion supplied to the hydraulic planter system.
