Prairie Special – 1500-3000L

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.

1. 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.
2. 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.
3. 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.
4. Boom rest. The adjustable height boom rests with rubber supports provide a soft contact point for the boom wings, minimising the chance for damage.
5. Boom parallelogram lift. The mechanism provides boom height adjustment as well as the vertical suspension.
6. 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.
7. 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.
8. 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.

The small frame Prairie Special can be optioned with practical features suited to Rowcrop spraying.
Horticultural Rowcrop spraying is far more intensive than broadacre, with tight headlands, narrow wheel tracks and higher water rates required to do an efficient spray job. Option your Prairie Special with the Rowcrop Hitch to allow for over 90 degree turning articulation at the end of each row. 11.2 R44 (270/95R44) Rowcrop wheels can be fitted to suit 64” wheel track centre. Large capacity Zeta 260MI pump can be fitted with a hydraulic motor drive to allow for turnable hitch and higher water rates.

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.

Today’s sprayers are full of bells and whistles which makes spraying a whole lot easier, comfortable and efficient, but it’s easy to forget what the end goal is. Precise chemical application.
Boom control can be the difference between a good spray result, and no result at all. Goldacres understand this and it is why all our sprayer designs are centred around the boom first and foremost.

Why do Goldacres booms ride so well?
Goldacres pioneered the use of lightweight aluminium in the outer boom wings over two decades ago. The philosophy was, and still is today, that mass on a boom is fine so long as it is as close to the centre as possible. Reduced mass on the boom extremities reduces boom forces in both yaw and roll. This combined with the unique boom suspension results in a very stable boom ride, regardless of the terrain.
TriTech booms are contour following, meaning that the boom level will be referenced to the sprayer chassis and not purely on gravity such as a pendulum boom. This allows the sprayer to transverse the sides of hills and contours whilst keeping the boom level to the ground at all times. This results in placing the nozzle at the optimum height above the target.

Application made easy
The Delta boom range is ideal for growers looking to benefit from the proven stability and performance of the three-way suspension system in an economical package. Designed for light to medium duty applications with widths ranging from 15m to 24m*. Standard features include mild steel inner wings with lightweight aluminium outer wings, single operation boom folding system featuring the proven cable control with outer wing break back functionality, full size ¾” boom lines to minimise pressure drop across the sections for consistent spray application and full hydraulic lift and fold.

SuperFlow 40 or 60L Induction Hopper
Lower the hopper into the loading position by simply releasing the spring-loaded catch, the SuperFlow hopper enables you to load powders, granules and liquids fast – up to 20 kg/min* (Atrazine) using a large flow venturi system.
The lower valve has a large handle that’s easy to grip while wearing PPE and features push down drum rinse nozzle, tank flushing nozzle and simple tank level calibration.

Transcal (not shown)
The 45L Transcal is a simple and effective way of transferring and measuring liquid chemical.
Using a venturi the Transcal can draw chemical from an open container using a probe, or out of an envirodrum, to provide a totally enclosed transfer system.
The Transcal measures chemical transferred by volume, not flow, providing accuracy regardless of the liquid viscosity.

Venturi Probe
Standard on all models across the range, the probe is a simple method of transferring chemical into the main tank directly from a drum. It uses a venturi mounted in the main product tank.
Chemical transfer pump (4000 & 5000L only)
The 12 volt chemical transfer pump has an open flow of up to 40 l/min and can transfer chemical from any container using a probe or envirodrum coupling.
The chemical transfer pump features an optional integrated flow meter to keep track of how much chemical has been transferred, providing a completely stand-alone transfer system at the flick of a switch.
