Tank Agitation
There is a tank agitator in the sprayer tank that shoots a jet
of liquid out at a high velocity. This keeps the pesticides in
suspension. The agitator has three holes and is oriented
as shown in Figure 5-3. To ensure that the tank gets prop-
er agitation, make sure that the agitator is always kept in
the orientation shown.
Storage
1. Empty solution from the tank, clean the chemical in-
ductor (if included), and store or dispose of the chem-
ical as recommended by the manufacturer’s chemical
label.
2. Flush the entire sprayer system with clean water.
3. Clean out Whirlfilters ® . Refer to Operating Whirlfilter ®
in the “Operating Instructions” section on page 12.
4. Circulate 3 - 5 gallons of antifreeze (Great Plains
strongly recommends the use of recreational vehicle
antifreeze) through the system including the pump,
hoses and nozzles.
5. The cast iron pump must be either full of RV antifreeze
or completely empty of all liquid to avoid corrosion. If

the contents of the pump is unclear it is advisable to
drain the pump, remove it, and place it in a warm dry,
environment during the winter.
6. Remove nozzles, disconnect the control box, and
place them indoors with the pump.
7. Change filters in the tractor cab after finished.
8. Wash off the exterior of the sprayer thoroughly using a
safe solvent or soap and water.
9. Inspect all parts of the sprayer for wear and rust. Re-
pair and paint parts as necessary.
10. Store the sprayer in a dry area away from direct sun-
light.
IMPORTANT: Regular antifreeze is harmful or fatal to
animals and humans. Use carefully according to the
label’s instructions. We strongly recommend the use
of recreational vehicle antifreeze which does not ex-
hibit these harmful side effects.
