Spraying Solutions Other Than Water
Since all the tabulations are based on spraying water, which
weighs 8.34 lbs per USA gallon, conversion factors must be
used when spraying solutions which are heavier or lighter than
water. To determine the proper size nozzle for the solution to be
sprayed, first multiply the desired GPM or GPA of solution by
the rate conversion factor. Then use the new converted GPM or
GPA rate to select the proper size nozzle.
Example: Desired application rate is 20 GPA of 28% Notrogen.
Determine the correct nozzle size as follows:
GPA (Solution) x Conversion Factor = GPA
20 GPA (28%) x 1.13 = 22.6 GPA (Water)
The applicator should choose a nozzle size that will supply 22.6
GPA of water at the desired pressure.

Miscellaneous Conversion Factors
One Acre = 43,560 square feet = 0.405 Hectacre
One Hectacre = 2.471 Acres
One Gallon Per Acre = 9.35 Liters Per Hectacre
One Mile = 5280 Feet = 1610 Meters = 1.61 Kilometers
One Gallon = 128 Fluid Ounces = 8 Pints = 4 Quarts = 3.79
Liters = 0.83 Imperial Gallons
One Pound Per Square Inch = 0.069 bar. = 6.895 Kilo-Pascals
One Mile Per Hour = 1.609 Kilometers Per Hour
Higher pressure not only increases the flow rate of the nozzle,
but it also influences the droplet size and the rate of orifice
wear. As pressure is increased, the droplet size decreases
and the rate of orifice wear is increased.
The values given in the tabulation section of this owners
manual indicate the most commonly used pressure ranges for
the associated spray tips.

Calibration
Chemical labels may show application rates in gallons per
acre, gallons per 1000 square feet, or gallons per 100
square feet. You will note that the tip chart shows all 3 of
these rating systems.
Once you know how much you are going to spray, then
determine (from the tip chart) the spraying pressure (PSI),
and the spraying speed (MPH).
Determining the proper speed of the pulling vehicle can be
done by marking off 100, 200, & 300 feet. The speed chart
indicates the number of seconds it takes to travel the
distances. Set the throttle and with a running start, travel the
distances. Adjust the throttle until you travel the distances in
the number of seconds indicated by the speed chart. Once
you have reached the throttle setting needed, mark the
throttle location so you can stop and go again, returning to
the same speed.
Add water and proper amount of chemical to the tank and
drive to the starting place for spraying.
Tip Selection
Important note:
The tips supplied as standard with this boom assembly are
number TP8003VP tips. when you refer to the rate charts
found in this owners manual, these rates are based on
water. Please read this tip selection section carefully
before attempting to operate your boom assembly
The selection of proper tips for the boom is determined by
the gallon per acre (GPA) requirement which is specified
on the chemical label. The following characteristics also
have a determining factor and must be considered:
Speed of spraying (MPH) 1.
Boom nozzle spacing (specified in inches) 2.
Solution weight and conversion factor (CF) 3.
Gallons of solution to be sprayed per acre 4.
Spraying pressure 5.
Useful Formulas:
GPM - Gallons Per Minute
GPA - Gallons Per Acre
MPH - Miles Per Hour
10. Hook an end of each boom chain on an “S” hook
attached to the top bar tube. Slip a slide clamp onto each
outer boom. Place the other end of the boom chain
between the ears of the slide clamp and secure with a
3/8” X 1” flange screw. Level the outer booms by moving
the slide clamps in or out as needed. Tighten the bolts in
the slide clamps to hold the clamps in place.
11. Attach the appropriate hose assemblies onto each of
the three boom sections. The center section has five
nozzles, with “L” connectors on each end.
12. Join the designated feeder hose from the tee valve
sub-assembly to each boom section and secure in place
with hose clamps.
