An agricultural machine applies liquid material to a field. Valve control signals control valves to apply the liquid material. Row pressure on the agricultural machine is sensed to identify when the valve is opened to apply the liquid material. The valve control signals are generated, based on the row pressure, to control the valves to apply the liquid material at a desired location in the field, relative to plant locations in the field.

Embodiments of the disclosure relate to an applicator for an adhesive primer. The applicator includes a tank configured to hold the adhesive primer. The applicator also includes a peristaltic pump, having an inlet and an outlet, and a spray nozzle. A first conduit extends from an interior of the tank to the inlet of the peristaltic pump, and a second conduit extends from an outlet of the peristaltic pump to the spray nozzle. Embodiments of the present disclosure also relate to a method of applying adhesive primer to a road surface using the applicator. In the method, the adhesive primer is pumped from the tank containing the adhesive primer through the peristaltic pump to the spray nozzle. Further, the adhesive primer is sprayed from the spray nozzle onto the road surface while the applicator moves across the road surface.

Apparatus for blending and applying plural substances including aggregate onto an environmental substrate is shown and described. The apparatus includes optionally a single power plant, plural pumps each fed by a respective hopper, and a blender blending pumped materials together. Dispensing ratios of the two pumps are mutually adjustable. An onboard air compressor delivers compressed air for atomizing blended materials as they are dispensed with the aggregate. Because materials may be curable or hardenable, flushing is enabled. The apparatus may be a free standing wheeled device.

A dispensing system includes a mobile dispensing device, a fluid transport device, and a fluid supply module. The mobile dispensing device includes a dispensing mechanism carried by a first frame including a first track portion. The fluid transport device includes a second frame supported by at least one wheel for rolling movement of the second frame on the substrate, with the second frame including a second track portion. The fluid supply module includes a base member and at least one reservoir carried by the base member and connectable with the dispensing mechanism for dispensing a fluid stored in the at least one reservoir. The base member includes a third track portion selectively engageable with either one of the first and second track portions for releasable assembly of the fluid supply module with the corresponding one of the mobile dispensing device and the fluid transport device.

A sprayer equipment includes a support frame, a pump, a pressure regulator, a concentrate tank, an injector, a spray nozzle, and a controller. The support frame has a plurality of wheels. The pump is coupled to the support frame and includes a pump inlet configured to be fluidly coupled to a water source and a pump outlet providing water at an increased water pressure. The pressure regulator is configured to control the pressure of the water. The concentrate tank is supported by the support frame and configured to store a concentrate fluid. The injector is fluidly coupled to the concentrate tank and configured to inject the concentrate fluid into the water. The spray nozzle is fluidly coupled to the pump outlet and the injector. The controller is coupled to the injector and is configured to control operation of the injector.

A method and apparatus for mounting a pump stack in a self-propelled agricultural product applicator utilize a pump stack mounting arrangement including a pump stack, a crossmember with a web having an opening providing clearance for passage through the opening of at least one successive pump of the pump stack, and a removable mounting plate adapted for attachment to the crossmember and the at least one successive pump on an opposite side of the crossmember from a proximal end of the pump to provide support for a distal end of the pump stack. By removing the mounting plate, detaching any successive pump in the stack from its immediately preceding pump in the pump stack, and moving the detached part of the pump stack axially through the opening, clearance is provided for servicing a pump in the stack without removal of the whole pump stack or the crossmember.
