You can have two VT screens fitted as an option allowing the operator to view multiple applications at the same time. Highly efficient mechanical driveline lightweight design and superior power-to-weight ratio. The mechanical driveline is offered in either two or four-wheel drive with multiple wheel track options. This allows the G4 to be configured to suit just about any cropping configuration. Powered by the Cummins B4.5 engine, renowned for its reliability and performance, paired with an Allison 6-speed automatic transmission, guaranteeing not only exceptional power delivery to the ground but also optimal operating efficiency. Engine and Transmission Cummins B4.5 engine produces 149 kw (200 hp) of power and 780 Nm (576 lb-ft) of torque. A rear engine power take off (REPTO) drive permits a large variable displacement hydraulic pump to be fitted. Peak hydraulic flow is rated at 215 l/min. Allison 2500 6 speed auto transmission with close radio gears provides more gears in the spraying speed range (15-25 km/h). Drop legs Power from the axles is transfered through to the wheel through the oil bath chain drive and planet hub reductions. Simple, efficient and reliable. Drive axles High horsepower rated differentials transfer the power to the droplegs using large universal joints. Fixed track sprayers feature a rear diff lock for when the going gets really tough. – 2 or 3m fixed track – 2WD – 3m fixed track – 4WD – 2-3m hydraulic track adjust – 2WD – 3-4m manual track adjust – 2WD Four Wheel Drive (4WD) system The 4WD system utilises a single speed transfer case with front axle disconnect, allowing the sprayer to be used as a 2WD sprayer, helping to reduce fuel usage. At the flick of a switch the front axle can be engaged, providing an equal power split between front and rear axles. If the going gets really tough, then the rear differential lock feature can also be engaged. Fuel tank }A 375L fuel tank is installed, with an average fuel consumption of around 15 liters per hour*, this allows for approximately 25 hours of spraying between refills. The sprayer boasts a torsionally rigid semi-truss structure chassis, ensuring unparalleled balance between strength and weight. The chassis is constructed as a semi-truss rigid non-flexing design which provides the foundations as to which the sprayer is built around. Suspension system The suspension system uses a 5 link arrangement (4 x parallel links and 1 x pan hard link) at each end of the sprayer. The rear axle features an extra heavy duty sway bar to help keep the sprayer chassis level to the ground at all times. Each corner is supported by air springs which are placed as wide apart as possible to improve sprayer stability in undulating terrain. Operator comfort To make the long days as comfortable as possible the G4 features a suspended cabin that is positioned behind the front axle which greatly reduces vertical movement, thus improving the ride for the operator. In addition the engine and transmission are supported by hydraulic dampened rubber mounts which dramatically reduces noise and vibration levels felt by the operator. Chassis surface treatment Every Goldacres fabricated component is given the special treatment when it comes to corrosion protection. First the item is shot blasted to remove any surface contaminates, rust and scale. It is then sealed with a high build primer / sealer before being treated to a high gloss durable 2 pack top coat which is oven baked. The resultant finish is one that will last for many years in the most demanding conditions. Fitted with the proven TriTech boom with a balance between strength, lightweight and simplicity, avalaible in 24, 28, 30 and 36m widths. Boom control can make the difference between a good spray result and no result. Goldacres understands this, which is why all our sprayer designs prioritize the boom. Goldacres pioneered using lightweight aluminum in the outer boom wings over two decades ago. The philosophy is that mass on a boom is fine as long as it is close to the centre. Reduced mass on the boom extremities lessens forces in both yaw and roll. Combined with unique suspension, this ensures a stable boom ride, regardless of terrain. TriTech booms follow contours, referencing the boom level to the sprayer chassis instead of gravity like a pendulum boom. This keeps the boom level to the ground on hills and contours, placing the nozzle at the optimum height above the target. Centre Section Provides control for the boom. Featuring TriTech suspension, the centre section uses hydraulics to control boom yaw and dampeners for the roll. Pitch of the boom is controlled via hydraulic accumulators fitted to the paralift cylinders. Inner Wings Steel RHS truss structure provides strength and flexibility to support outer wings. Outer Wings Full truss aluminium construction featuring a semi riveted outer wing in high stress areas to provide strength while being lightweight. Three dimensional breakaways are fitted to the end boom sections. Outer wing folding is controlled by front and rear cables. Plumbing 1” boom plumbing is fitted for both higher application rates but to also reduce pressure drop along the length of the boom. Height Control XRT radar boom height control can be fitted an option. TriTech boom centre section – Why is boom ride and stability so important? A boom which bounces, sways or yaws deposits chemical unevenly on the target. This can result in weed escapes and may even contribute to resistant weeds. Pitch – The boom parallelogram lift design provides boom height adjustment as well as the vertical boom suspension (pitch) with the use of accumulators in the lift circuit. Roll – The key to the superior boom ride is the strategically placed delta links. In all, there are four links. Each link features spherical ball ends which allow the centre to move in all directions. The roll centre point is the location at which the boom pivots around, both in roll and yaw. Roll dampeners reduce high-frequency oscillation of the boom roll. Yaw – Two opposing hydraulic cylinders are mechanically connected together either side of the pivoting boom centre section. As the centre yaws one cylinder is retracted, the other is extended. This results in oil movement which compresses in a nitrogen charged accumulator. The result is precise boom yaw control. RapidFire is instant boom nozzle on / off capability with up to 16 section control. Allow quick line priming and flushing of spray lines with RapidFlow boom recirculation. RapidFire – Goldacres pioneered RapidFire technology on Australian built sprayers in 2006. At the time the new technology vastly improved section switching times by replacing traditional motorised boom section valves with a central bank of air solenoids and spray stop valves mounted right at the nozzle. Booms configured in 16 sections use our direct master technology. This further improves response times for on/off switching over the central bank design. The boom is configured in 10 sections with 16 sections optional to improve spray resolution when using an auto section controller for odd shaped paddocks. We have found that 16 sections provides the perfect balance between spray overlapping and complexity. RapidFlow (Boom Recirculation) – RapidFlow allows the sprayer boom lines to be fully primed without spraying a single drop. This reduces wastage at the start of a tank load or when switching chemicals. RapidFlow can also be used to thoroughly flush out the boom lines without the need to physically spray on the ground. The three tier system (3TS) uses a combination of nozzles to maintain the spray nozzle pressure within a defined pressure band. The spray nozzles operating pressure range and size determine the application rate and speed band at which the driver must adhere to. This band is usually quite narrow. Goldacres offer a 3-tier system (3TS) which effectively gives the driver a much wider operating band whilst maintaining optimum droplet size and spray rate. Think of 3TS as a three-speed gearbox. 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 the nozzle reaches the top of its pressure band the first nozzle will switch on again, effectively giving three nozzle operating bands. The table above shows the pressure variations of two common nozzles, 015 and 02 operating at 70 l/ha through their respective pressure ranges from 7 km/h through to 30 km/h. A wheel track to suit many broadacre and horticultural cropping applications. Wheel track width requirements can vary sigificantly depending on crop types and geographic regions. Choose from either a 2 or 3m axle fixed track width, hydraulic track adjust from 2-3m or manual track adjust from 3-4m. Fixed, manual or Hydraulic track adjustment In all there are 5 different axle configuration available: – 2m fixed track – 2WD – 3m fixed track – 2WD – 3m fixed track – 4WD – 2-3m hydraulic track adjust – 2WD – 3-4m manual track adjust – 2WD
