3. Calculate the individual nozzle output
using the following equation.
L/Ha (A) x Spacing
LPM =
Output per Nozzle (D)
4. Set the correct pressure.
a. Replace one tip and strainer with an
identical new tip and strainer. Refer to the
application chart and locate the pressure
that will give the nozzle output calculated in
step three for the selected nozzle tip. A
Flow Rate and Application Chart for the XR
type nozzle tip is included on page 56 of

descriptions for a variety of nozzle types that can
be used with the MacDon Field Sprayer. Before
starting the spray application, consult your dealer if
you need more information on the nozzle tip.
NOTE: Set the agitation valve before
calibrating the sprayer. Open the valve to increase
agitation. Close the valve to reduce foaming. Do
not change the setting during sprayer calibration.
b. Start the engine. Enter the application rate
in the MT-3405 rate controller. While the
rate controller is in calibration mode, toggle
the switch to test speed. Enter the ground
speed.
CAUTION: Be sure area is clear of
bystanders, then start engine.
c. Start the sprayer pump and increase the

switch in the "RUN" position. Do not exit
calibration mode on the rate controller.
WARNING: Operate the sprayer away
from areas frequently traveled by
family and other people.

water through the booms for one minute.
e. After the nozzle pressure has been adjusted,
measure the volume output from the new
spray tip. Place a collection container under
the nozzle for one minute and collect the
output.
WARNING: Ensure other personnel are
trained properly and always wear the
same protective equipment and take
the same precautions that are required when
handling chemicals and preparing to do an
application.
The volume collected in the container must equal
the individual nozzle output calculated in step three.
Adjust the reel speed and conveyor speed dials to
fine tune the output pressure from the nozzle to get
the correct volume.
