A system for dispensing multiple low rate agricultural products, includes an agricultural product metering system, a number of agricultural product tubes, and an agricultural product metering system. The agricultural product metering system is operably connected to sources of low rate agricultural products. The agricultural product tubes are operatively connected to the agricultural product metering system. The agricultural product metering system is configured to dispense liquid low rate agricultural products at a low rate defined as below 3.7 fluid ounces per 1000 row feet.

A global navigation satellite system (GNSS) based control system is provided for positioning a working component relative to a work surface, such as an agricultural spray boom over a crop field. Inertial measurement unit (IMU) sensors, such as accelerometers and gyroscopes, are mounted on the working component and provide positioning signals to a control processor. A method of positioning a working component relative to a work surface using GNSS-based positioning signals is also disclosed. Further disclosed is a work order management system and method, which can be configured for controlling the operation of multiple vehicles, such as agricultural sprayers each equipped with GNSS-based spray boom height control subsystems. The sprayers can be remotely located from each other on multiple crop fields, and can utilize GNSS-based, field-specific terrain models for controlling their spraying operations.

The invention relates to a method for dispensing a particulate material in a target area and a device suitable for use in the method. The method comprise (i) providing a reservoir comprising openings for the particulate material, (ii) providing a number of closing means suitable for at least partially closing the openings of the reservoir (iii) providing a number of screens in the void of the reservoir, said screens being movable, through the void of the reservoir between at least a first and a second position (iv) loading particulate material in the reservoir, (v) moving the reservoir loaded with particulate material over the target area and at least partially opening the number of openings while alternatingly moving the screens between a first and a second position and vice versa.

An agricultural machine includes a chassis, a product tank, a support boom, and an applicator assembly including a frame and a nozzle. The frame has a first portion and a second portion. A coupler assembly is coupled between the support boom and the applicator assembly. The coupler assembly includes a first coupler portion having a female component and a collar, and a second coupler portion having an anti-rotational mechanism and a male component. The first coupler portion is coupled to the support boom and is in communication with the product tank. During assembly, the male component is inserted into the female component and the collar engages with the male component to mechanically couple the applicator assembly to the support boom and fluidly couple the nozzle to the product tank. The anti-rotational mechanism is coupled to the support boom to reduce rotational movement of the applicator assembly.

An apparatus for dispensing biological control agents, the apparatus comprising: a hopper for containing biological control agents, the hopper comprising an orifice arranged to allow the dispensation of the biological control agents therethrough; and a valve wheel arranged outside the hopper and adjacent to the orifice, the valve wheel being arranged to rotate about a valve wheel axis to move the biological control agents away from the orifice.
