Assembly Instructions
Tools Needed For Cart Assembly
(2) 1/2” Wrenches
(1) Pair Needle Nose Pliers
Remove from Carton
Remove all parts and hardware packages from the carton. Lay out all parts and hardware and iden-
tify them using the illustrations pages 2-3.
Assembly Tip: Loosely tighten all nuts and bolts at first. Fully tighten when the unit is completely
assembled.
1. Place the Tow Bar Tubes under the front of TCT Cart Frame. Take four 1/4” x 2” Hex Head Bolts,
place a 1/4” Flat Washer on each bolt, insert the bolts into the first two frame holes on each side.
Insert the bolt through the Frame holes and through the Tow Bar Tubes, add one more 1/4” Flat
Washer to each bolt and secure with 1/4” Nylock Nuts. Insert 1” Tube Plugs into front holes of Tow
Bar Tubes. See Figure 1.

Sprayer Calibration
Proper calibration is one of the most important parts of spraying. Properly calibrated sprayers will save you
both time and money.
How to determine the gallons per minute (per nozzle).
GPM=GPA x MPH x W
5940
GPM—Gallons Per Minute
GPA—Gallons Per Acre
MPH—Miles Per Hour
W—Nozzle spacing (in boom spraying)
This formula is useful to determine which tip to use on your boom, especially when your nozzle spacing is
different from the standard 20” or 40” nozzle spacing on Precision Products, Inc. Sprayers. For example: You
know you want to travel 3 MPH., apply the chemical at a rate of 20GPA. The nozzle spacing’s are 33” on cen-
ter. By using the formula you will determine how many gallons per minute (GPM) per tip will be required to
give you the correct application.
Example: 20 GPA x 3 MPH = 60 x 33” (nozzle spacing) = 1980 divided by 5940 + .333 GPM
You have now determined that you need a tip with GPM of .333. Find the type of tip you want to use. For
example, an 80 degree flat fan spray tip and then determine what pressure you plan to spray at. Let’s say 30
PSI. How do you check this calibration? By using this formula.
GPA = 5940 x GPM (Per Nozzle)
MPH x W
Multiply 5940 x .333 GPM + 1783.8. Multiply 3 MPH x 33 (nozzle spacing) = 99. Divide 1783.8 by 99 = 18.06
gallons per acre.
By simply adjusting your pressure or your tractor speed, you will obtain the 20 GPA rate.
The second formula is used to determine whether an old tip (one on which you cannot identify the number)
is still spraying the right amount of chemicals. You can determine how many GPM a tip is spraying, with the
use of a catch jar and stop watch. Hold the jar under the tip so you catch the total spray for one minute. The
amount in the jar indicates the GPM.
Calibrate your sprayer carefully. If your tips are worn, replace them. New tips are a fraction of the cost of us-
ing either too much or too little chemicals. Also, you can use these formulas to help determine if the intended
pump has the volume capacity to meet your spraying needs.
