General
Filtration
Filtration is a critical part of the sprayer's
performance.
As standard, these sprayers are fitted with:
1 x Suction filter 32 mesh
2 x Pressure filters 1 x
Nozzle strainers (50 or 100 mesh)
pra
There is a choice between two different styles of
spray pump no these machines: A centrifugal 400L/
min at 8 Bar spray pump and a positive displacement
oil backed diaphragm pump capable of 260L/
min. PTO drive is standard and a hydraulic drive
is optional where a diaphragm pump is fitted. The
normal operating range is from 1 - 8 bar which is
sufficient for efficient no le performance.
• Each individual boom section has a maximum
delivery of 35 litres per minute with clean filters
fitted.
The maximum combined flow of all boom
sections is limited to 140 litres per minute, or 50%
of the pump flow, whichever is the lesser amount
with clean filters.
• Centrifugal spray pump: Running the pump dry
will cause failure. Care should be not to operate
at speeds exceeding 4,400 rpm.
• Diaphragm spray pump: Care should be taken
to never overfill with oil or operate at speeds
exceeding 540 rpm.
• Do not exceed the maximum spraying pressure
of 8 Bar.
Chemical Induction
The method of chemical induction into your sprayer
is dependent on the optional chemical induction
e uipment fitted to your sprayer.
Goldacres chemical induction equipment available
includes:
• Chemical Probe
• Chemical Induction Hopper
• 12 V Chemical Transfer Pumps
• Direct Chemical Injection Modules
Booms
These sprayers can be fitted with a variety of
boom sizes from 24 metres and up to 48 metres
in width. TriTech booms feature hydraulic lift, fold
and individual wing tilt controllable from the towing
machine.

Goldacres TriTech booms feature pitch, roll and yaw
suspension in order to provide a superior boom ride
and assist in the efficient application of chemical to
your target.

As information regarding no les is specific to those
being used in your application, no specific reference
is made to nozzle application rates or nozzle types in
this operator's manual. Goldacres suggest the use of
a current TeeJet or Lechler nozzle selection catalogue
for reference to nozzle sizes, outputs, spray patterns
and general spraying information. For more technical
information on the function of spray nozzles and
factors affecting their performance you can also use
the TeeJet 'User's guide to spray nozzles'.
The TeeJet & Lechler nozzle selection catalogue and
Users guides to spray nozzles are available from your
Goldacres dealer, or as a free download from the
TeeJet web site: www.teejet.com
Lechler web site: www.lechler.de

The 3 Tier System (3TS) aims to give a wider
range of flexibility around application rate and
spraying speed. The 3TS effectively gives the driver
a much wider operating band whilst still maintaining
optimum droplet size.
The 3TS can be thought of as a three step gearbox.
Each nozzle type has an operating pressure band for
a given droplet si e. As the first no le set, or tier,
reaches the top of its pressure band, the next larger
size nozzle tier is activated.
When the second tier reaches the top of its
pressure band, the first tier will be reactivated to
spray at the same time. This effectively gives three
operating bands.
Ma ine i itation
All Goldacres equipment is subject to operating
limitations, it is the operator's responsibility to
ensure that this equipment is being operated within
these limitations and appropriately to the operating
conditions at hand.
Goldacres do not endorse use of this machine
for spraying at speeds greater than 20 km/hr.
Violent speed change WILL CAUSE boom damage.
Operating on rough terrain can be harsh on the
machine even where a suspension system is fitted.
Stop the machine and inspect for damage after
impact with gutters, sinkholes, rocks etc.
