Abstract: A method for assembling a spray pattern adjustment assembly for use with a spray head assembly is provided. The spray head assembly may define an outlet passage that has a height. The method may include the steps of inserting the spray pattern adjustment assembly having a reduced height compared to the height of the outlet passage into the outlet passage, increasing the height of the spray pattern adjustment assembly to at least match the height of the outlet passage, and substantially fixing the position of the spray pattern adjustment assembly relative to the spray head assembly.

Abstract: A fluid delivery system includes a first hydraulic circuit, and a second hydraulic circuit. The first hydraulic circuit includes a first hydraulic pump, and a first hydraulic motor. The first hydraulic motor is fluidly connected to the first hydraulic pump and is configured to be driven by the first hydraulic pump. The second hydraulic circuit includes a second hydraulic pump, and a second hydraulic motor. The second hydraulic pump is mechanically coupled to the first hydraulic motor and configured to be driven by the first hydraulic motor. The second hydraulic motor is disposed in loop with the second hydraulic pump and configured to be driven by the second hydraulic pump. The fluid delivery system further includes a delivery pump mechanically coupled to the second hydraulic motor and fluidly connected to a fluid source. The delivery pump is configured to deliver a pressurized fluid.
