A foldable rear boom section of an agricultural product applicator includes at least one first tube connected to a first end of a respective at least one second tube and a hinge assembly coupled to the first and second tubes and configured to pivot the second tube with respect to the first tube about a pivot axis. Further, a nozzle is connected to a second end of the second tube. Pivoting the first and second tubes about the pivot axis causes the foldable rear boom section and the nozzle to transition between an extended position and a retracted position.

A hinge system is provided for a boom of an agricultural product applicator that facilitates a compact folded boom width in a transport mode by providing a multi-directional folding, including folding with compound movement components to reorient a primarily horizontal stack of boom sections to a primarily vertical stack of the boom sections, when fully folded. The hinge system may include multiple hinge joints with pivot axes that are oriented at different angles to allow for substantially horizontal folding movements followed by a rolling-type movement(s) that reorients a generally horizontal stack of boom sections into a generally vertical stack of boom sections to decrease an overall width of the applicator when in transport mode.

A global navigation satellite system (GNSS) based control system is provided for positioning a working component relative to a work surface. Inertial measurement unit (IMU) sensors, such as accelerometers and gyroscopes, are mounted on the working component and provide positioning signals to a control compute engine. A method of positioning a working component relative to a work surface using GNSS-based positioning signals is also disclosed.

A product distribution system for sectional control in an air boom spreader has a solid product metering assembly having: a first endless conveyor and a second endless conveyor for conveying the product from the container to the air system, the first and second endless conveyors substantially parallel to each other, the first conveyor driven independently of the second conveyor; and, a first shaft, a second shaft and a third shaft, the first shaft parallel to, separated from and driven independently of the second shaft, the second shaft parallel to and separated from the third shaft, the first shaft driving the first conveyor, the second shaft driving the third shaft to drive the second conveyor.

A system for dispensing liquid agricultural products with seed includes an agricultural product supply system configured to dispense agricultural products. The system includes a seed tube for introducing seed. A tube-mounted nozzle is positioned on the seed tube for introducing liquid agricultural product into the seed tube. A gaseous fluid line is in fluid connection to a source of gaseous fluid. A gaseous fluid bubble generation assembly is in fluid communication with the gaseous fluid line. The gaseous fluid bubble generation assembly is configured to generate bubbles. The gaseous fluid bubble generation assembly is arranged and constructed so that when the gaseous fluid from the gaseous fluid line is passed therethrough bubbles are generated and agglomerated when the gaseous fluid encounters the liquid agricultural product within the seed tube.

A method of improving the performance of a powder dusting tip delivering powdered diatomaceous earth powder minimizing clogging in powder bulb duster tips through the use of tips with a more free flowing configuration and different spray patterns than the standard tip assembly and a flexible one piece powder dusting tube, which is attached to the tips which connects to reservoir of powder type insect repellents such as diatomaceous earth pesticides, boric acid pesticides, sevin based insecticides, deltamethrin based insecticides, and permethrin based insecticides as well as other powdered insecticides through threaded connections, made from flexible rubber tubing supported by memory wire that allows the powder duster tip to be positioned for hard to reach areas.

A product distribution system for sectional control in an air boom spreader has a solid product metering assembly having: a first endless conveyor and a second endless conveyor for conveying the product from the container to the air system, the first and second endless conveyors substantially parallel to each other, the first conveyor driven independently of the second conveyor; and, a first shaft, a second shaft and a third shaft, the first shaft parallel to, separated from and driven independently of the second shaft, the second shaft parallel to and separated from the third shaft, the first shaft driving the first conveyor, the second shaft driving the third shaft to drive the second conveyor.

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.

A system for dispensing low rate agricultural products, includes a syringe-based agricultural product metering system, at least one agricultural product tube, and an agricultural product metering system. The agricultural product metering system is operably connected to a source of low rate agricultural products. The agricultural product tube is 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.
