25 Operating Instructions
The agitation can be set by adjusting the agitation pres-
sure valve while the pump is at operating speed. Adjust
the valve until you get the desired agitation pressure you
would like on the agitation pressure gauge.
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.
Operating Pump
To operate the PTO pumps, engage the PTO shaft slow-
ly at the tractor’s idle throttle position. Slowly accelerate
to the desired PTO RPM (On a 540 RPM pump it is rec-
ommended to operate the pump at 540 RPM and on a
1000 RPM pump it is recommended to operate the
pump at 1000 RPM). Disengage the PTO at any RPM to
stop the pump.
!
WARNING
Never operate the PTO pump without the tractor PTO shield
in place, and the pump torque bar firmly chained in place.
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/Hydrau-
lic Pump Hook-Up” on page 20, for more details. To run
the pump, push the hydraulic lever in the “down” posi-
tion. When you want to stop the pump, push the
hydraulic lever 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.
Filling Tank Procedures
!
CAUTION
When filling the sprayer tank, use a check valve or anti-siphon
device to prevent the solution in the tank from infiltrating into
the fresh water source and contaminating it.
Your Great Plains Sprayer fills the tank from the bottom
of the tank and uses a standard 2 inch Cam-Lock cou-
pler to connect to the freshwater hose. An 1 1/2 inch
camlock coupler is also available as an accessory. Refer
to "Quick Fill Assembly" in the parts manual.
1. To fill the tank, hook up the freshwater hose to the
quick-fill camlock coupler with the quick-fill ball valve
in the closed position.
2. Turn the water on and open the quick-fill ball valve
for the freshwater to enter the tank. When using a
positive displacement pump to fill the tank, open the
quick fill ball valve first and then pump water into the
tank.
!
CAUTION
Do not add the chemical until you are at the field, just prior to
spraying. When you add the chemical, follow the manufactur-
er’s instructions for mixing the spray solution in order to
achieve the desired application rate.
!
CAUTION
Read the manufacturer’s label carefully before handling
chemicals.
3. Before you add the chemical to the tank, make sure
the tank is at least one half full. The concentrate
should not be poured into an empty tank.
4. Keep the spray solution away from all skin. Wear
protective clothing and goggles. If the solutions
comes in contact with the body, wash off the con-
taminated area with soap and water.
5. Keep chemical containers low when pouring.
6. Let the wind blow fumes and dust away from you
while pouring the chemical.
7. DO NOT smoke while handling chemicals.
