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. Refer to Hydraulic El-
evator Option in the “Operating Instructions” section on
page 19. 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 accord-
ingly. Refer to the Nozzle Charts in the Application Guide
located in this manual to determine 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 calibrated
for if the sprayer is not equipped with a monitor. Watch the
pressure gauge and be aware of changes in the pressure.
Tank Straps
The tank straps that wrap around the sprayer tank may be-
come loose after the first few hours of operation. This oc-
curs when the tank settles in the saddle. Polyethylene
tanks are especially susceptible to this. Retighten the tank
straps to secure the tank.
Agitation Adjustment
The agitation valve is used to adjust the pressure to the
agitation nozzles in the tank. Refer to the agitation gauge,
and adjust the pressure to a desired rate. Different chem-
icals require different agitation pressures to keep the
chemical in suspension.
!
CAUTION!
If using liquid fertilizer or any other chemical that will corrode
brass, install a gauge protector under the brass agitation gauge
or plug the gauge hole. Failure to do so will eventually cause the
gauge to fail and chemical to be expelled from the gauge.
Agitation Adjustment with Tank Rinse
Refer to Figure 18
The agitation is adjusted the same way when the sprayer
has the Tank Flush option. The only difference is the
plumbing to adjust it. Rotate the agitation valve to achieve
the desired pressure on the agitation gauge.
