Rate Control Valve
This valve, located behind the tank (Fig. 20), controls the
amount of fluid that is routed to the booms by directing
fluid flow to the booms or the bypass hose to the tank. You
can control this valve in two ways: the application rate
switch or manually. To control it manually, you need to
disconnect the wire connector on the valve, then you can
rotate the knob on top of the valve to manually obtain the
desired pressure.

Flowmeter
The flowmeter measures the flow rate of the fluid for use
by the Spray Prot system (Fig. 20).
Boom Valves
These valves turn the three booms on or off (Fig. 20). If
you do not have a boom installed or do not want a boom to
be able to be turned on, you can manually operate each
valve by disconnecting the wire connector in the valve,
then rotate the knob on the valve clockwise to turn the
valve off or counterclockwise to turn it on.
Boom Bypass Valves
The boom bypass valves redirect the fluid flow for a boom
to the tank when you turn off the boom section. You can
adjust these valves to ensure that the boom pressure
remains constant no matter how many booms are on. Refer
to Adjusting the Boom Bypass Valves, page 25.
Agitation Control Valve
This valve is located on the right side of the tank (Fig. 21).
Turn the knob on the valve to the 9 o'clock position to turn
on the tank agitation and to the 3 o'clock position to turn
off the tank agitation.

1. Agitation control valve
For agitation to work, the pump must be on and the engine
must be running above an idle. If you stop the sprayer and
need agitation on, place the range selector in the Neutral
position, set the parking brake, press the accelerator pedal
to the floor, and turn the neutral engine speed control on.
Pressure Gauge
The pressure gauge is located to the right of the tank
(Fig. 21). This gauge shows the pressure of the fluid in the
system in psi and kPa.
Pump
The pump is located near the front of the tank on the right
side (Fig. 22).
