Installation
Adjusting Wheel Track (optional fixed axle)
The wheel track may require adjusting to match
the track of the tractor or to increase the stability
of the sprayer.
Use the maximum track on sloping terrain if
possible.
Lift the sprayer with a jack and support it with
stands under the drawbar and each side of the
frame behind the wheels.
On the standard axle loosen the four axle U-bolts
and the four set screws in the axle adjustment
sleeve. Slide the axle shaft on each side to the
required track and retighten the U-bolts and set
screws securely.
With standard tyres fitted the track may be set
between 1500 and 1580 mm, over the outside of
the tyres. Use an equal offset each side and do
not exceed the maximum track setting as this will
prevent proper engagement of the axle sections.
The track on the standard Glideflex axle is unable
to be adjusted.
Adjusting the Fan
The Supaflo fan has four separate adjustments
which can be used to regulate the air flow to suit
particular applications.
1. Air Gap
The volume and velocity of the airflow
can be regulated by adjusting the gap between
the fan cowl and the mounting plate for the spray
nozzles. Moving the cowl in reduces the gap and
increases the air velocity, which is best suited to
vines and similar close plantings. Moving the cowl
out reduces the air velocity but increases the
volume, which is more suited to larger canopy
tree crops such as citrus fruits.
The cowl slides on two bars at its base and the air
gap is regulated by the threaded rod at the top.
To adjust the gap, use a 5mm Allen key to loosen
the two grub screws on the underside of the cowl
that lock onto the slide bars. Loosen the nuts on
the top threaded rod and move the cowl to the
desired position. The minimum gap is 100mm and
the maximum is 140mm. After adjusting, retighten
the nuts and grub screws.
2. Air Wedges
The air wedges are located on the
forward face of the fan cowling at the 10 o’clock
and 2 o’clock positions. Removing the wedges
increases the air flow to the upper area of the tree
canopy in crops such as apples and citrus fruits.
To remove the wedges, first remove the two 6mm
attaching bolts on each wedge.
3. Airflow Adjusters
An airflow adjuster is
located at the base of the fan on either side to
influence the direction of airflow. When angled
upwards the adjusters direct the airflow upwards
to suit free growing trees and taller crops. In the
horizontal position the adjusters direct the air
more laterally for spraying vines and small to
medium height crops.
The adjusters are positioned by removing the
outer attaching bolt, pivoting them to the required
location and reinstalling the outer bolt.
4. Blade Pitch
The pitch angle of the fan blades
can be adjusted to match the power output of the
tractor if required.
The larger the pitch angle the greater the volume
of air that will be displaced and the higher the
tractor power that will be required.
Normally when there is sufficient tractor power the
fan should be operated at full pitch and if a lower
volume of air is required the fan gearbox should
be set in the low speed position.
Do not attempt to adjust the track with
the tank filled or partly filled with liquid
or without the sprayer being properly
supported. Do not use the jockey wheel.
