Boom Options

Fen e ine et
Goldacres offer manually and electrically operated
fence line jets. The 'fenceline' jet is designed to enable
the operator to spray right up to the boundary
fence without having the boom too close to the
fence.
This should prevent operators from putting the
boom into the fence, especially important when the
operator is not familiar with the width of the boom.
The fenceline jet should be turned off after the end
of the first lap and this can be done either manually
via a tap or remotely via an optional electric solenoid
(controlled via the tractor cabin).

TriTech booms can incorporate a hydraulic bi-fold
option which allows the boom outer sections to be
folded in to make the entire boom smaller.
or example a 36 metre TriTech boom fitted with
the bi-fold option would fold back into 18 metres
swathe width for easier spraying in tight situations.
A centre leveling system is fitted only to sprayers
with bi-fold optioned. The centre leveling system
holds the centre section level with the sprayer
chassis when fold or bi-fold functions are activated.
This helps with the even folding of the wings.
See the section at the end of this chapter for
information on ad usting booms fitted with bi fold.

The Three Tier System (3TS) consists of two
complete and totally separate boom lines on the
same boom frame. As an example a conventional
30 metre boom has one boom line with 60 nozzle
outlets (2 per metre) across its width. A 3TS boom
replicates this first line with a second line also
consisting of 60 nozzles giving a total of 120 nozzles
for both lines.
In simple language, the 3TS gives you the capacity
to vary application rates and speeds by switching
extra nozzles on and off. The 3TS allows a
range of speed changes without the spray quality
being compromised – the correct droplet size is
maintained.
Importantly you can use the nozzles you want to
use - including air induction nozzles. That means
higher speed spraying without the limitations of large
droplet size.

Typically no les on the first line may flow at 15
flow rate and the no les on 3TS's second line at
25. When spraying, the first no les automatically
switch off when they reach full operating pressure
allowing the second line nozzles to commence
spraying. As speed increases again and the second
line nozzles reach their maximum operating pressure,
the first line no les will switch on again.
Thus, the flow rates of 15, 25 and 4 can be
achieved while maintaining the optimum droplet size
and spraying pressure. The 3TS delivers everything
needed for precision application at variable speeds.

Boom Height Control systems maintain the boom
at a preset height by monitoring field contours and
making responsive boom adjustments. Using data
from either 3 or 5 ultrasonic sensors, the Boom
Height Control systems makes responsive height
adjustments allowing booms to automatically follow
the contours of the land Maintaining spray nozzles at
the recommended spray tip height allows chemical
to be applied using an optimum spray pattern
providing even application and reducing drift.
Boom Height Control reduces the need for the
operator to move their head back and forth to
monitor changes in field terrain, thereby reducing
stress and fatigue.
This allows the operator to focus on machine
operation and safety. Manual operation of a sprayer
in uneven field terrain may re uire reduced
operating speeds for continual boom adjustments.
Ultrasonic sensor hardware and software is
designed specifically for height control applications.
The ultrasonic signals can distinguish the difference
between the ground and standing crop or field
residue. Boom height is controlled by choosing Soil
Mode (senses the soil surface), Crop Mode (senses
the top of the crop), or Hybrid Mode (technology
that calculates a virtual top of the crop for more
accurate control).
Refer to manufacturer's manual(s) for detailed
information about this system.
