Plumbing Operations
Refer to Figure 7
Figure 6 shows the basic plumbing diagram for the
sprayer. A basic knowledge of how the sprayer is
plumbed will help you to understand how to operate
your Great Plains Sprayer. Throughout this manual,
the components on this diagram will be described with
the terminology labeling these components.
Fluid is drawn out of the sump in the tank and passes
through the pump. From the pump it passes through
the solution whirlfilter
® and filters out or grinds up all
undissolved chemical and solid particles. The fluid
then passes through both the Flow Meter and the By-
pass Control Butterfly Valve.
The Bypass Control Butterfly Valve controls how much
fluid goes to the boom. This is regulated by the Raven
SCS 440 controller. The fluid passes through the Flow
Meter and proceeds to the 3-Way Boom Manifold
valves. If a Boom Valve is on, the fluid passes to its per-

nozzles. Refer to page 26 for a layout of the boom
plumbing.
The agitation can be set by adjusting the agitation pres-
sure valve while the pump is at operating speed. Refer
to Application Guide to adjust the agitation.
There are tank shut off valves everywhere there is an
outlet from the tank so that if there is a leak, the source
can be shut off and the chemical spill reduced. These
valves need to be wide open when the sprayer is in use.
To operate the hydraulic pump, first make sure that the
hydraulic hoses are routed correctly so that the pump
turns in the correct direction. See the “Tractor/Hydraulic
Pump Hook-Up” on page 17, for more details. To run the
pump, push the hydraulic lever in the “down” position.
When you want to stop the pump, push the hydraulic le-
ver in the “float” position.
IMPORTANT: Do not move the hydraulic lever to the
neutral position while the hydraulic pump is running.
To do so may cause damage to the hydraulic pump.
