ADJUST GROUND SPEED
It will be necessary to establish a travel
speed and then set the flow to give the
desired application rate. Always run at the
established travel speed.
However, the best results are obtained when
the ground speed is 8 - 13 kph (5 - 8 mph).
Ground speed variations in the field will
automatically be compensated.
Always operate at a comfortable speed. Do
not operate so quickly that the toolbar, trailer,
or tank bounces while going through the
field.
Effective results require that liquid be applied
at a consistent depth in a consistent manner.
Machine bouncing will prevent this required
consistency.
For broadcast spraying
Figure 21: Broadcast travel pattern
It is recommended that the operator makes
one pass around a field to start and then
spray back and forth to obtain the best
results. Using a marker system helps to
prevent skips or overlaps.
If your field has headlands, be sure to allow
sufficient space for turning.
For row crop spraying
Start at one edge of the field and go back and
forth until the field is completed.
Be sure the sprayer is calibrated, the nozzle
height and pressure are known, and the
tractor gear and RPM are determined before
starting to spray (see SPRAYER
CALIBRATION .)
Proceed down the field at a constant speed.
Use the selected gear, engine RPM and
ground speed determined during the
calibration of the machine application rate.
