Adjustments
The following table summarizes the available adjust-
ments. Not all are in this section of the manual.
General Field Adjustments
Boom Height
After calibrating the sprayer for the specific nozzle that
will be used at a desired pressure and tractor speed, the
main field adjustment is the boom height. See “Boom
Height” on page 49. Depending on which type of nozzle
is being used, set the boom height so that the correct
overlap for that specific nozzle is achieved. If the crop
canopy is taller in some fields than others adjust the
boom height accordingly. Refer to the Nozzle Charts in
the Application Guide located in this manual to deter-
mine the height of the boom needed.
EXAMPLE: A 2.5 Metercone nozzle at 20 inch spacing is
being used. From the Nozzle Chart (refer to the Applica-
tion Guide), a height of 19 to 21 inches above the top of
the crop is required. If the crop is 6 inches off the ground,
the boom height should be set to 25 to 27 inches off the
ground.
Nozzle Pressure
Another area that will need some field adjustments is the
nozzle pressure. As the tank level decreases the boom
pressure may need to be adjusted to keep the pressure
at the same magnitude for what the sprayer was cali-
brated for if the sprayer is not equipped with a monitor.
Watch the pressure gauge and be aware of changes in
the pressure.
