If size matters then the large frame three-point linkage is for you. Designed as an alternative to a trailed sprayer with tanks sizes ranging from 1500L through to 2000L and three different boom styles from 15m to 28m.
The versatility of the large frame 3PL has meant it has found homes in cereal, cotton and horticulture areas right across Australia. All models are fully configurable to suit your individual needs.
The frame utilizes thick walled Australian made steel to create an extremely strong structure, essential when fitting wider booms. The key to its strength is the combination of square and rectangle hollow sections (SHS & RHS) and precision laser cut plates placed in strategic locations. The frame is also very narrow which helps to keep the boom as close as possible to the tractor wheels for better weight distribution. The tractor pick up points are designed to suit a category three linkage equipment. Retractable support legs provide stability when the sprayer is disconnected from the tractor.
Goldacres four stage paint process. 1. Grit blasting which cleans and prepares the steel surface for the ultimate paint adhesion. 2. High build primer / filler flattens out the surface and is key to giving the top coat not only an optimum substrate to adhere to but that smooth “wet” look. 3. Wet top coat using the highest quality Australian made paint. Specially formulated for Goldacres the top coat provides a finish which has excellent mar resistance (the resistance to abrasive action like scratching) and also a very high tolerance to aggressive chemicals. 4.High temperature baking which cures the paint
Australian made rotationally moulded thick wall UV stable tank with an extra deep centre sump design. Smooth internal wall aids rinsing and decontamination. The tanks are available in 1500, 1800 and 2000L capacities.
100L saddle style rinse tank mounted to the top of the main product tank. The rinse tank can be used to flush out the pump and boom lines at the end of the spray job whilst still in the field.
Tank level sight tubes (main and rinse tank) allows the operator to visually check volumes from inside the tractor.
High volume high pressure (170 l/min 20 bar) three piston diaphragm pump with 540 rpm PTO shaft provides smooth consistent water flow to the boom. If more flow is required then this pump can be upgraded to a 260 l/min unit.
A pump suction filter with three way ball valve allows the operator to switch between drawing from the main tank and the rinse tank. The off position also allows the strainer to be removed and cleaned even when the sprayer tank is full.
Twin pressure line filters greatly reduce the chances of nozzle blockages. The first filter is a coarse mesh while the second is finer.
Venturi agitator fitted to the tank greatly improves the consistency of the tank mix over the course of the spray job.
Chemical venturi probe is used to draw neat chemicals into the main tank. This type of chemical induction means that at no stage does neat chemical come into contact with the pump, which could cause corrosion problems.
Plumbed from the external filling point the internal tank rinse nozzle with rotating head quickly and easily decontaminates the inside of the tank.
Top mounted bottom fill allows the water to be pumped in through the top of the tank and down to the bottom. This method reducing foaming and also reduces the risk of contaminating the water source if the transfer pump stops unexpectedly.
All spray hoses are constructed using a Nitrile liner. This liner helps resist the effects of the most aggressive of chemicals from damaging the hose.
Electric section and pressure regulation control is fitted for easy in cab adjustment. While an external control station is used to operate auxiliary functions like chemical transfer and agitating. An adjustable pressure regulator valve is fitted to set the maximum system pressure.
Choice of three different booms. Refer to booms section for more information.
Options
Induction hopper. The 40L capacity chemical induction hopper is an integrated chemical transfer system that allows liquids, granular and powdered products to be measured and transferred into the main tank. The hopper has both drum and internal rinsing capabilities. The high flow venturi is mounted at the base of the hopper which draws chemical into the water stream at that point, minimising the chance of blockages.
Raven SCS450 and SCS4400 automatic rate controllers adjust the flow rate according to speed to maintain a consistent spray application rate. Features include up to five boom sections control on the SCS450 and seven section on SCS4400, pre-set application rates plus a manual mode, display of ground speed and flow rate plus many other counters.
ISO BUS control system. This system allows the sprayer to be controlled using a virtual terminal (VT) which might also be used for other duties, like mapping or tractor steering. The brains of the system, called a node is mounted to the sprayer, this node does all the control work. The VT simply displays and communicates all the information to the operator. Can control up to ten boom sections.
Do away with the pto shaft with a hydraulic drive kit. Neatly adapts to the existing pump and is run directly from the tractor remotes. When used in conjunction with the Raven SCS450 then pump rpm can also be monitored. If a non-Raven monitor is fitted then Goldacres can supply a separate pump rpm monitor.
An electric over hydraulic manifold can be fitted to the sprayer if your tractor does not have enough hydraulic remotes. The manifold is fitted with flow control valves and load holding checks where required and can be configured to control up to six functions.
45L exacta foam marker can be installed as a simple, low cost alternative to a GPS system. The exacta foam marker uses separate water and detergent tanks. Final mixing with the liquid and air is done out at the boom ends with a foam generator to produce high volumes of dense foam. Available in single or double-sided.
Ultrasonic boom height control systems can be fitted to the TriTech series of booms. A combination of ultrasonic sensors mounted on the boom wings and onboard computers adjust the wing tilt hydraulic cylinders to help maintain a consistent boom height above the target. Perfect for use in.
Got steep or rugged terrain you need to spray? The Pro-Reel® auto rewind Traymount sprayers allow you to spray wherever you may roam. Take the work out of hose reel spraying.
Designed with operator safety and convenience in mind the RTV300 features a forward mounted 300L chemical tank for extra stability. In addition, a rear mounted single 100m Pro-Reel® is fitted and provides a compact layout suited to most RTV vehicle tubs.
The petrol engine driven pump is rated at 40 l/min @ 40 bar (580psi), this allows the operator to apply large volumes of chemical over a large area in a very short amount of time. Excess flow from the pump is used to keep the chemical tank well agitated, ensuring a good even chemical to water mix at all times.

Rowcrop Hitch
Turning is important. Tight, difficult turns at the end of rows can use up a large amount of spraying time. A turntable hitch which permits tighter turning, speeds up spraying where there are narrow plantings or boundaries near the end of rows.
Call us control freaks!
In today’s fast-changing precision farming landscape it is easy to be left behind in the technology stakes.
That’s why Goldacres make it easy, with multiple solutions to suit the basic requirements to the top end needs.
For more than two decades Goldacres have relied on Raven to provide complete flow control systems with matched components to give quite simply, unmatched flow control accuracy and stability.
At the heart of the control system is a positive displacement pump run at constant rpm. This creates known flow rates across varying pressures, essential for accurate and stable flow control. In addition, two system critical components, a flow meter and three way regulator valve* combine to help achieve fast “on target rate”, plus greater flow stability with known tank agitation.
The Prairie Special range of sprayers feature three controller types to suit all requirements.
3 way electric section and regulation control system
For simple fuss-free flow and section control the 1500-2500L small frame Prairie Special can be fitted with a three section switch box with electric pressure regulation, this allows the operator to adjust the spray pressure to achieve the desired nozzle flow rate. The operator then drives at a set ground speed to maintain the correct application rate.
SCS450 Auto rate control system
The proven SCS range of sprayer consoles provide simple, fuss-free control of the flow control duties. The SCS450 features up to 5 boom section control, 2 pre-set auto rates plus manual pump speed readout, ground speed and several counters. If you are looking to further expand the capabilities, then the SCS range is compatible with all the leading automatic section controllers on the market.
ISO BUS Auto rate control system
Tractor cabins can get very busy with the vast range of systems requiring individual control consoles. The ISO BUS standard virtual terminal (VT) brings all the systems together into the one display. Essentially each system contains the brains, while the VT is simply the interface between the two. This means only one operator console is required.
Goldacres offer the option for ISO BUS compatibility, allowing numerous leading VT displays to take over the sprayer control duties. Features like flow control pressure, pump speed readout, plus all tractor steering and task control applications can all be all monitored by the one display.
Construction
To build the best sprayer you have to start with a solid platform
The small frame Prairie Special design incorporates many elements to ensure maximum strength, longevity and performance. Features such as, fully bushed pivot points, precision laser cut components and the best corrosion proof paint system. Fully welded in rotating positional jigs ensures accuracy, repeatability and quality all combined with the experience gained with thousands of sprayers in the field.
Chassis. Manufactured from high strength heavy walled 125x75x6mm RHS to minimise flexing and provide a stable platform for boom mounting. The rear chassis section features an integrated boom and tank support (3000L version only). Long wheel base (axle to drawbar) provides excellent boom yaw stability and reduces sideways pushing forces at the tractor.
Drawbar pull. Single 150mm square drawbar section allows tighter headland turning. Full 360 degree swivel forged tow eye ensures maximum articulation between sprayer and tractor. Walk through platform. Access the main tank easily and safely from either side of the sprayer. No need to walk around the sprayer or tractor to access the other side. Open foot treads provide safe access to platform in muddy conditions. Lower portion of treads fold up out of the way when not in use.
Boom rest. The adjustable height boom rests with rubber supports provide a soft contact point for the boom wings, minimising the chance for damage.
Boom parallelogram lift. The mechanism provides boom height adjustment as well as the vertical suspension.
Delta boom centre section. Using lightweight trussing techniques the boom centre section is light yet extremely strong. All high load pivot points are greaseable, ensuring a long service life and optimum boom suspension performance.
Paint and anti-corrosion system. All major components are fully grit blasted using a fractured steel shot, essential for excellent paint adherence. The bare steel components are then treated using a high build filler primer which flattens the blasted surface. All un-welded joints are seam sealed then top coated using Goldacres’ exclusive chemical resistant paint formula. Finally all components are baked in a high temperature oven until fully cured. All zinc plated pins and bolts on the boom are coated with rust preventative G15, which adds another level of corrosion protection.
Full modular construction. The full modular construction technique allows many options to be easily added at the time of build or at a later date as required. Dealer Fit Options (DFO) can be retrofitted without the need for welding or drilling existing components.
