ELECTRIC OVER HYDRAULIC BOOM CONTROL BOX
Run the control loom back to the sprayer through a
convenient outlet in the tractor cabin ensuring that
it does not rub on any sharp edges. If it is
necessary to drill a hole in the cabin, fit a rubber
grommet. The loom is fitted with a 4 pin quick
release coupling for connecting to the sprayer.
If an optional foam marker is fitted at the factory,
the wiring for the marker will be incorporated in the
loom and the Foam Marker switch on the control
box can be used to operate the marker.
Adjusting the Axle Track Width
The track width between the wheels can be
adjusted to suit the row spacing of the crops being
sprayed. It can be set between a minimum of
1524mm (60 inches) and a maximum of 1828mm
(72 inches) measured between the centrelines of
the tyre treads. As delivered from the factory the
track is set to the minimum width.
Caution: As it is necessary to get under the
sprayer to adjust the track, follow the safety
precautions stated below.
Before adjusting the track, empty the tanks and
place the sprayer on a flat hard surface. Do not lift
the sprayer with fluid in the tanks.
Loosen the nuts on the U-bolts at each side of the
axle just sufficiently for the axle halves to be
moved in or out by the turnbuckles, which are
positioned on the front face of each axle half.
Loosen the locknut on each turnbuckle and
lengthen or shorten it, using a bar in the holes, to
move the axle halves in or out until the desired
track width is achieved. Adjust the turnbuckles by
an equal number of turns. Measure the track width
between the centres of the tyre treads.
Check whether the axle is central by measuring
the distance between the sprayer frame and the
inner face of each tyre. This should be equal on
each side. If necessary adjust the turnbuckles to
centralise the axle.
Position the centre bar connecting the two axle
halves so the lug marking its centre is midway
between the inner ends of the axle halves. This will
ensure the bar is inserted equally into each axle.
When the required track width has been set and
the axle is centralised, tighten the locknut on each
turnbuckle. Tighten the nuts on the U-bolts then
tighten the 16 lock-bolts securing the axle halves
to the centre bar. Recheck to ensure that all
hardware is securely tightened.
Raise each side of the sprayer in turn with the jack,
remove the support stand and lower the sprayer.
Note: U bolts are shown fully unscrewed and
axle lowered for clarity of the illustration only.
U bolts should only be loosened to adjust axle.
Sprayer Frame
Disconnect the sprayer from the tractor and
support it at the front on the folding support stand.
Lift each side of the sprayer in turn with an
hydraulic jack and lower it onto a steel support
stand placed under the main frame so that the tyre
on each side is just clear of the surface.
Ensure the support stands are of the same height
and capable of safely supporting the weight of the
sprayer (see Specifications page). Do not work on
the sprayer whilst only supported by the jack.
Loosen the 16 square headed lock-screws that
clamp the right and left axle halves to the centre
bar. On each axle half, there are four screws on
the underside and four on the rear face.
