Goldacres has one of the widest model offerings available for trailed sprayers, with popular sellers in both the Prairie Compact line offering 1000 to 2000-litres and the Prairie Specials jumping up to 2500 to 6500-litre product capacities.
But sitting very confidently at the top of the Australian-built Goldacres range of trailing sprayers is the Prairie Pro designed for broadacre applications.
The Prairie Pro is available in four product tank sizes, 5000, 6500, 7500 and 8500-litres, with TriTech boom widths ranging from 24 to 48 metres. To tie everything into any particular operation, multiple wheel track and tyres sizes can be specified and airbag suspension is standard in the larger models.
Boom innovations has long been a specialty of Goldacres, so as you would expect, Prairie Pro models are equipped with many leading technologies as standard.
To ensure the greatest accuracy, operators are treated to Rapid Fire nozzles and RapidFlow boom recirculation.
The Prairie Pro 8548 is the largest model in the line-up and comes equipped with an 8500-litre product tank and a TriTech V boom that offers spraying widths of 20, 36 and 48m.
The boom on the 8548 is 100 per cent Australian designed and built and a reminder that Goldacres was a pioneer in the use of lightweight aluminium in its outer boom wings over two decades ago.
It is well accepted now that the resulting reduction in mass on the boom extremities reduces boom forces in both yaw and roll. The result, a stable boom ride, regardless of the terrain.
TriTech booms are also 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 while keeping the boom level to the ground and placing the nozzle at the optimum height above the target.
Hydraulic yaw is now standard on all TriTech boom widths.
This function precisely controls the forwards and backwards movement of the boom wings and is instrumental in minimising any under and over application of product.
All TriTech booms are constructed using lightweight trussing techniques, and this has the advantage of a stronger design without weight, the enemy of boom agility.
The Prairie Pro 8548 is designed with the Goldacres EZ Control Station that positions all filling and flushing functions in one convenient location.
The sprayer is equipped with a 260 litre/min hydraulic pump to deliver chemical to the nozzles.
While it is optional, Prairie Pro 8548 buyers should include Goldacres 3TS technology for the Rapid Fire nozzle system, it incorporates a valuable three-step process.
Each nozzle type has an operating pressure band for a given droplet size. As the first nozzle reaches the top of the pressure band it switches off and the next larger size nozzle switches on.
When that nozzle reaches the top of that pressure band the first nozzle will switch on again, effectively giving three operating bands.
For rate control the Prairie Pro 8548 is equipped with the Raven SCS4400 sprayer console as standard. An upgrade to ISOBUS control is also an option.
Goldacres has ensured the main tank can easily and safely be accessed from either side. Open foot treads provide safe access to the platform in any conditions, and the lower portion folds out of the way when not in use.
