An agitation unit for use in a lawn spreader and other dispensing equipment, and oscillating agitation systems therefor comprising such an agitation unit. The agitation unit includes a hub, an arm extending from the hub, and an extension on the arm configured to project downwardly to an extent relative to the arm and the hub to protrude into, but not through, the outlet passageway of the hopper.

Device for delivering solid particles on demand, intended for agricultural machine, wherein the delivery on demand of solid particles to a receiving device is regulated, particularly in the field of technology for transporting solid granulated materials by means of an air stream, without being exclusive, in agricultural machinery when an air stream is used to transport seeds or fertilizer granules from at least one central hopper to the dosing/metering equipment located on the sowing unit, and including a source of pressurized air, a distributor of solid particles “S”, a hopper whose bottom feeds solid particles “S” to the distributor and a plate permeable to the passage of air and on which said particles “S” settle.

The present inventors have determined that implementation of an authentication process which can be selectively applied to safeguard parameters which modify dispensing of particulate material during agricultural operations can advantageously allow users of varying levels of experience and understanding to maintain ease of conducting field operations while reducing the possibility of waste and expense. A control system can determine a level of access for an operator or user on an individual basis. Upon determining a level of access for the operator to be sufficient for modifying a parameter, the control system can apply an input from the operator to modify the parameter, and can accordingly adjust dispensing of particulate material.

One or more techniques and/or systems are disclosed for metering assembly for an agricultural seeder. The metering assembly can be configured for quick and easy removal and replacement, where merely the assembly is removed without disassembling other parts of the seeder system. An improved coupler, in conjunction with a threaded knob device, allows for quick and easy access to the assembly, for removal and replacement in a metering tube. A visual indicator can be disposed on the end of a rotating shaft to provide a user with a quick confirmation that the assembly is properly rotating during operation.

A particle delivery assembly of an agricultural row unit includes a particle tube configured to receive a particle and to deliver the particle toward a trench in soil. The particle tube includes a first body portion, a second body portion, and a hinge coupled to the first body portion and to the second body portion. The hinge is configured to enable the first body portion and the second body portion to pivot relative to one another between an open position of the particle tube and a closed position of the particle tube.

A vehicle for receiving and delivering granular material, such as agricultural seeds, includes a frame supporting a container defining an open top chamber having a bottom outlet. An elongated conveyor is supported by a system which includes a first support arm having one end pivotally connected to a side wall of the container for multiple directional movements and a second support arm pivotably connected to the opposite end of the first support arm. The opposite end of the second support arm supports an intermediate portion of the conveyor near its center of gravity and in suspended relation for tilting and rotating the conveyor. Power actuators are connected to rotate and pivot the first support arm to position the conveyor in many selected positions including the conveyor inlet under the outlet of the chamber, a storage position and a position between horizontal and substantially inclined for filling other containers.

A crop input transfer system for transferring a crop input to an implement tank supported on an implement dispensing the crop input, the crop input transfer system includes a mobile supply vehicle powered independent of the implement. The mobile supply vehicle has a boom and a supply tank holding a crop input supply. The crop transfer system includes a coupler with a first coupler portion that matingly couples with a second coupler portion. The first coupler portion is mounted to the boom and the second coupler portion is mounted to the implement. The crop input supply in the supply tank is communicated to implement tank via the matingly coupled first and second coupler portions.

Methods, apparatus, systems and articles of manufacture are disclosed for efficient material application. An example landscape treatment apparatus includes a main carrier tank to store a solvent, a concentrate tank to store a solute, and a first mix tank to receive the solvent and the solute as a first mixture. The example apparatus further includes a second mix tank to receive the solvent and the solute as a second mixture, where the first mix tank is to receive the solvent and the solute in alternation with the second mix tank receiving the solvent and the solute. The example apparatus also includes a boom to apply the first mixture and the second mixture to a landscape via a plurality of nozzles, where the boom is to apply the first mixture and the second mixture in alternation.

Described herein are systems, methods, and apparatus for agricultural planting including selecting and varying agricultural input types during an in-field operation. In one embodiment, a method calculates a partial addition of seed to a seed pool during planting to minimize or eliminate seeds in the seed pool (520) as a boundary is crossed.

A tool assembly for a planter row unit resides at the forward end of the row unit beneath the tool bar. The assembly includes a bracket assembly connected to the row unit, with a ground engaging tool removably mounted on the bracket assembly for movement between raised and lowered positions. A linear actuator controls the position of the tool. The tool may also include a depth control mechanism. Different tools can be interchanged on the bracket assembly.
