SPRAYER ADJUSTMENT AND CALIBRATION
ADJUST THE HEIGHT OF BOOM
The height of the sprayer booms is adjust-
able between 18 to 60 inches (46 to 152
cm) depending on tractor size and height.
Height is regulated by the tractor lifting or
lowering the sprayer. The size of the trac-
tor affects the height of the sprayer.
When height adjustment is necessary fol-
low these steps.
Adjust the height of the boom according to
the instructions of the chemical being
applied. If not specified adjust the booms
to be 18 to 20 in (45 to 50 cm) above the
target of the spray. Spray pattern from
nozzles should overlap a couple inches
above the spray target.
Stop tractor engine, place all controls in
neutral, set parking brake, remove ignition
key and wait for all moving parts to stop
before servicing.
Calculate the height adjustment needed to
determine where to make the adjustment.
NOTE: Height adjustment can be made
at the 3 point hitch or at the wings, or
both.
