Spray Boom Operation
The RowKING sprayer is normally fitted with a
Silvan RowMASTER Vegetable Boom of 12 or 15
metre width. Field operation of the boom is
described below. Refer to the Boom Operators
Manual for information on boom safety,
specifications, adjustment and maintenance.
The standard method of boom control is by three
sets of remote outlets on front mounted booms and
two sets on rear mounted booms, using the tractor
levers for the lifting and folding operations
If optional electric-over-hydraulic controls are fitted
only one set of remote hydraulics is required.
Lifting and folding is controlled by the switches on
the cabin box. Three bank controls are needed for
lifting and folding and five bank if the optional outer
wing fold or individual wing tilt is fitted.

ELECTRIC OVER HYDRAULIC BOOM CONTROL BOX
Electric-Over-Hydraulic Boom Controls
Silvan electric-over-hydraulic controls enable all
operations to be controlled by one set of tractor
remotes. The lift and fold functions and optional tilt
function, if fitted, are selected by using the
switches of the cabin control to operate solenoid
valves on the sprayer that connect the appropriate
hydraulic circuit.
The control box also incorporates a Master On/Off
switch and a 3-position switch for the optional foam
marker. Two vacant switches are available for
connecting other equipment and the system is
protected by a 10 amp fuse on the rear of the
control box.
To operate the boom, the lever controlling
hydraulic flow to the remote outlet is set to the
open position. The Master switch of the control box
is set to “On” and all further boom movements are
controlled by the switches on the control box.
Raising or lowering the “Lift” switch raises or
lowers the boom. Ensure that the hydraulic hoses
are correctly connected so the boom moves in the
same direction as the switch. The lift hose can be
identified by the tap fitted at its end.
The “Main Fold” switch folds or unfolds both
sections of the boom.
The “Outer Fold” switch folds only the outer section
so that the boom can be used at reduced width.
When this position is selected it is necessary to
stop the outer section from spraying with the
section switches on the Silvamatic control box or
Farmscan controller.
Folding and Unfolding the Boom
Always ensure that the boom is folded or unfolded
in a safe area where it will not foul on any other
objects. Never fold or unfold near overhead power
lines. Ensure that all bystanders are clear and
sound the horn before moving the boom with the
tractor hydraulics.
The speed at which the boom folds or unfolds can
be adjusted, refer to the Boom Operators Manual
for details.
Unfolding. The arms rest on a resilient pad in a
support saddle on each side of the sprayer and are
not held by any lock mechanism. Before unfolding,
the boom must be raised so the arms can swing
clear of the saddle as the unfolding action occurs.
Use the “Main Fold” switch to unfold the arms. As
the arms unfold the outer section will swing
forward at the hinge, thus straightening the boom.
The boom can now be lowered for operation by
using the “Lift” switch.
Folding
To fold the boom, first raise it to full height to lock it
in the level position by using the “Lift” switch.
Use the “Main Fold” switch to slowly swing the
arms back over the support saddles. As the arms
swing back the outer section will fold back against
the inner section.
When the arms are fully folded use the “Lift” switch
to lower them onto the support saddles. Lower the
boom just sufficiently to rest fully on the saddles.
Check that a spraybar nozzle is not too close to
the saddle as it may be damaged as the boom
slides back and forth on the saddle during
transport over uneven ground. Raising or lowering
the boom slightly whilst folded will alter the position
of the nozzles relative to the saddle.
