An improvement to a roadside sprayer fixates spray nozzles on a registration plate. The registration plate may include integral tabs depending on the application. Inclination of the tabs is adjustable to place streams and droplets in a desired swath coverage. With the nozzles rigidly mounted onto the plate, the entire plate is nutated. The use of the registration plate in a spray unit creates a uniform nutation among the nozzles, thereby reducing variability in droplet placement, and providing a more predictable spray from the nozzles. In other embodiments, the spray unit is utilized in a spray system adaptable to service vehicles, and may be utilized in conjunction with a vegetation engagement device, such as a cutter to engage multiple zones of a roadway right-of-way. Additionally, an improved spray unit includes an electromagnetic field and an attractor to generate plate motion.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluid to plants in rows in a field includes a frame, at least one applicator arm disposed in a rhizosphere of plants during fluid flow through the applicator, and a fluid conduit connected to the frame and disposed in the row between plants to deliver fluid to the row between plants.

Apparatus for spreading fluids and in particular fertilizers, pesticides and similar fluids, with a connection for attaching said apparatus to a machine, with a tubular body for conducting the fluid, and with a first outlet device via which the fluid can be discharged. The outlet device can be fixed at various positions in a longitudinal direction of the tubular body such that a position of the outlet device can be selected relative to the tubular body.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a frame, a coulter connected to the frame and disposed to open a trench between the rows of plants, and at least one application member connected to the frame or to the coulter and disposed to apply fluid to a rhizosphere of the plants.

The present invention is directed to a nozzle holder, having a body, a dispensing chamber, a plurality of valves in the dispensing chamber, movable between an open and closed position, a rotationally movable plate in contact with a first end contact surface of each valve to control the movement of said valve between its two positions; wherein the peripheral edge of the plate has high and low edge portions, in the opening position of a valve, the first end contact surface is in contact with a first plate edge portion, and in the closing position, the first end contact surface of the valve is in contact with a second plate edge, the second edge being different from the first edge.

A method for applying two different sprays to agricultural land using an agricultural spraying device that includes a first spray circuit having a first spray tank and a first spray nozzle unit, and includes a second spray circuit, which is fluidically separate from the first spray circuit and has a second spray tank and a second spray nozzle unit. The method includes providing a first spray in the first spray tank. The method also includes providing a second spray in the second spray tank. The method also includes applying either the first spray using the first spray nozzle unit or the second spray using the second spray nozzle unit to field portions of the agricultural land depending on whether the at least one defined weed is present in each field portion.

A mounting arrangement and method are provided for securing a T-joint in a control cable connectable in electrical communication with an electrical device, such as an electrically controlled nozzle, attached to a mounting surface such as the boom of an agricultural product sprayer. The mounting arrangement includes a base block adapted for fixed attachment to the mounting surface, and a pair of first and second clamping shells adapted and cooperatively configured for attachment to the base block and one another to define an internal cavity of the mounting arrangement between the clamping shells and the base block for receiving and retaining the T-joint within the mounting arrangement. The mounting arrangement is attached to the boom with a single threaded fastener. The clamping shells are identical and lock to one another and the base block without additional fasteners.

An operator seat system is provided that includes an operator seat and an armrest control center with an I/O (input/output) system that is connected to and moves with the operator seat. An armrest control center mount system may include a seat mount and an armrest control center mount that are attached to each other with an adjustment system that allows adjustment of the armrest control center with respect to the operator seat.

Described herein are implements and application units for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, an application unit includes a frame to be positioned in operation between two rows of plants and a plurality of flexible members coupled to the frame in operation such that the plurality of flexible members guide a lateral position of the frame to be approximately equidistant from the two rows of plants based upon whether at least one flexible member of the plurality of flexible members contacts one or more plants of the two rows of plants. The plurality of flexible members include a plurality of fluid outlets for spraying crop input in close proximity to the rows of plants.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluid to plants in rows in a field includes at least one applicator arm that is actuated by an actuator to move the applicator arm from a position in the row between plants to a position adjacent to the plant.
