Goldacres Prairie Special 4000L-6500L

The large frame Prairie Special trailing range is a fully featured sprayer for growers looking for medium to large capacities.
The Prairie Special comes in tank capacities of 4000, 5000 and 6500L. It is available in two boom styles, Delta and TriTech, in widths ranging from 18m to 36m. Large diameter single wheels, fixed or airbag suspension axles and optional track widths provide the grower with a configuration for almost any situation. Built to a standard, not a price, the large frame Prairie Special gives you all the features and capacity you need with strength and durability you can depend on.
To build the best sprayer you have to start with a solid platform
The large frame Prairie Special design incorporates many elements from the transport and earthmoving industries to ensure maximum strength, longevity and performance. Features like fully bushed pivot points, air ride suspension components and dampeners, to the best corrosion proof painting systems. Fully welded in rotating positional jigs ensures accuracy, repeatability and quality all combined with the experience gained with thousands of sprayers in the field.

The sprayer chassis is Manufactured from high strength heavy walled 200x100x6mm RHS to minimise flexing and provide a stable platform for boom mounting. The rear chassis section is stepped in with integral boom and tank support allowing narrow wheel track options. Long wheel base (axle to drawbar) provides excellent boom yaw stability and reduces sideways pushing forces at the tractor. Narrow drawbar final section allows tighter headland turning. Full 360º swivel forged tow eye ensures maximum articulation between sprayer and tractor.

Walk through platform is provides access to 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 the platform in muddy conditions. Lower portion of treads folds up out of the way when not in use.

Specifically designed for the Prairie Special the air bag suspension system provides a smooth soft ride for both trailer and boom whilst still limiting excessive body roll. This is achieved through the use of the large diameter bi-functional rubber bush pivot system coupled with heavy walled torque tube construction. The bolt in axle also doubles as the air reservoir for the ride height levelling.

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. TriTech booms are available in sizes 24 – 36m for the large frame prairie special
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.
