Section 2 Operating Instructions
3P200 and 3P300 Three-Point Sprayer 500-103M 3/6/06
Great Plains Mfg., Inc.
!
CAUTION!
Do not add the chemical until the sprayer is in the field, just pri-
or to spraying. When adding the chemical, follow the manufac-
turer’s instructions for mixing the spray solution in order to
achieve the desired application rate.
3. Before adding 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 pro-
tective clothing and goggles. If the solutions comes in
contact with the body, wash off the contaminated area
with soap and water.
5. Keep chemical containers low when pouring.
6. Make sure the wind is blowing the fumes and dust
away from the operator while pouring chemical.
7. DO NOT smoke while handling chemicals.
Operating Pump
!
DANGER!
Rotating driveline contact can cause death. KEEP AWAY! Do
not operate without guards attached and driveline securely at-
tached at both ends.
To operate the PTO pumps, engage the PTO shaft slowly
at the tractor’s idle throttle position. Slowly accelerate to
the desired PTO RPM. On a 540 RPM pump, the RPM of
the PTO would be the speed at which the dead head pres-
sure reaches 80 PSI (Refer to Tractor/PTO Pump Hook-
Up on page 8) or 540 RPM. On a 1000 RPM pump, the
RPM of the PTO would be the speed at which the dead
head pressure reaches 80 PSI or 1000 RPM.
!
WARNING!
Never operate the PTO pump without the tractor PTO shield in
place, and the pump torque bar firmly chained in place.
1. 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 Hookup in the “Assembly and Setup” sec-
tion on page
9 for more details. To run the pump, push
the hydraulic lever in the “down” position. When stop-
ping the pump, push the hydraulic lever in the “float”
position.
NOTE: Do not move the hydraulic lever to the neutral po-
sition while the hydraulic pump is running. To do so may
cause damage to the hydraulic pump.
Hydraulic Elevator Option
Raise and lower to the desired boom height using the trac-
tor hydraulics. Make sure the boom doesn’t settle hydrau-
lically (lower in height) during the operation of the sprayer.
Clean out the tank-fill Whirlfilter ®
Refer to Figure 2-3:
1. Start with an empty sprayer tank.
2. Position a bucket under the plug in the sump of the
Whirlfilter
® and allow the grit to fall out.
3. Screw the plug back in using pipe thread sealant to
seal the plug.
4. Dispose of the grit and water in the same manner de-
scribed on the manufacturer’s label of the latest chem-
ical used in the sprayer.
Filling Tank Procedures
Your Great Plains Sprayer fills the tank from the bottom of
the tank and uses a standard 2 inch cam-lock coupler to
connect to the freshwater hose.
!
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.
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, refer to Figure 2-3.
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.
