G4V horticulture self propelled sprayer
The population is growing and the need for cheap, clean, green food is rising quickly.
Over the last 10 years the number of vegetable growers in Australia fell by 37%, yet the area planted still increased substantially.* The result is farms are getting a lot bigger, and so is the requirement for machinery. Introducing the all new G4V
Goldacres has observed this trend and designed a purpose built sophisticated sprayer that is suited to the horticultural industry. Whilst from a distance the sprayer may look similar to its dry land broadacre and cotton sprayer cousins, a closer look will show it’s much different. Horticultural operators require slower speeds, higher water rates, narrow wheel tracks and a tight turning radius.
The all new G4V sprayer from Goldacres offers a new level of performance and efficiency not seen before. The design is centered around a 4000L main product tank complimented by booms with widths up to 36m. Riding on large diameter 46” wheels and tyres combined with four wheel steering to provide outstanding ride and sprayer manoeuvrability. Cummins power coupled to a four wheel drive hydro mechanical driveline all adds up to give the G4V outstanding tractive performance and efficiency results in almost any situation.
The G4V has been packaged with an uncompromising level of quality components, integrated systems, operator ergonomics and high end specifications.
If you are serious about farming, then look no further than the G4V for your spraying solution.

Hydro-mechanical drive system & suspension system
The G4V Crop Cruiser utilizes a combination of hydrostatic and mechanical drive systems to transfer maximum power to all four wheels with minimum fuel usage.
At the heart of the system is a single high capacity variable displacement hydraulic pump and motor. These two components form the hydrostatic part of the drive system and allow the operator to adjust the sprayer speed in smooth infinite amounts. In addition, the onboard computer adjusts the engine rpm to precisely match the required speed setting. The result is fuel usage averages as low as 14 l/hr and reduced cabin noise.
Tight headlands, no worries
G4V four wheel steering equals more hectares for cropping.
The fully welded semi truss rigid chassis features narrow frame rails, unique chassis and boom suspension system to allow very sharp steering angles even with large diameter wheels.
The switchable four wheel steering (4WS) gives a turning radius of just 2.9m* (inside of tyre) when fitted with large diameter 380/90R46 tyres and a 1.81m wheel track.
The system is controlled using angle sensors fitted to both front and rear axles in conjunction with the central sprayer controller. When switching back to two wheel steering (2WS) the rear wheels will automatically self centre.
At speeds above 15km/h the 4WS will automatically disengage and revert back to 2WS. This greatly improves stability and safety at these higher speeds.
*Will vary depending on wheel track
A wheel track for every situation
Designed to suit many Rowcrop applications the G4V sprayers feature track width adjustment by changing the dish and rim configuration.
Wheel tracks from 1.81m - 2.36m can be achieved by reversing the bolted rim and disk to allow up to 16 track width variations. Tyre size 380/90R46. Special wheel tracks are avaialble upon request.

Long days and nights operating the sprayer can be demanding on the driver
That’s why the G4V Series Crop Cruiser features a premium cabin with essential features and comforts to help you get through. Goldacres designers have delivered a cabin that has everything you need, and nothing you don’t.
Stylish roof design with forward and rear facing lights (Not shown)
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 from the basic requirements to the top end needs.
For more than 2 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 high flow multistage centrifugal pump operated at consistent rpm. This multistage centrifugal pump provides high flow rates across a wide working pressure range compared to a single stage unit. This is essential for stable and accurate flow control. In addition, two system critical components, a flow meter and three way regulator valve, combine to help achieve fast “on target rate” and greater flow stability.
ISO BUS systems
Sprayer cabins can get pretty busy with the vast range of systems requiring individual control consoles. The ISO BUS standard brings all the systems together into the one display, called a virtual terminal (VT). 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
The SCS4400 sprayer console provides simple, fuss free control of the liquid flow duties. The SCS4400 features up to 7 boom section control switches (expandable to 10), manual pump speed readout, ground speed, three tier system (3TS) as well as several counters such as area and volume. If you are looking to further expand the capabilities, then the SCS4400 is compatible with most leading automatic section controllers on the market./p>
Strength, stability, reliability and control
The TriTech boom range is designed for operators who demand the utmost performance, reliability and control. Time and time again the TriTech boom has been named “No.1 for boom stability”*, which at the end of the day, gives a superior spray result.
Features such as hydraulic yaw which precisely controls the forwards and backwards movement of the boom wings to minimise the under and over applying of chemical is now standard on all widths.
The strategically placed centre section suspension links help isolate the sprayer chassis movement over rough terrain. Combined with the tuned damping characteristics allows precise roll control enabling an
All TriTech booms are constructed using lightweight trussing techniques, which allows for a stronger design without weight, the enemy of boom agility.

Boom suspension explained
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 result in resistant weeds.
The Goldacres TriTech suspension system has been developed to provide you with the best boom ride possible and assist in an accurate application. Working in conjunction with the chassis airbags the boom features three way suspension that works to reduce boom pitch, roll and yaw - the three enemies of accurate application. A combination of shock absorbers, hydraulic cylinders and accumulators all work together to provide the best boom ride possible.
The TriTech suspension system has contributed to Goldacres consistently having the best boom ride when measured against competitor machines.
A sprayer is only as good as its boom
Today’s sprayers are full of bells and whistles which makes spraying a whole lot easier, comfortable and efficient
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
Many farms and crop varieties have different requirements when it comes to chemical application systems.
The new V Series TriTech boom utilities a five chord layout on the inner wing with the main boom folding pivot points above the nozzles. This layout allows virtually any nozzle configuration and spacing width to be achieved./p>
Goldacres are able to configure the boom to include single, double, clock face 3-5 nozzles bodies, droppers and high volume air sleeve systems just to name a few. Wide choice of nozzles available from leading brands such as TeeJet and Lechler.
RapidFire and RapidFlow nozzle switching technology
Goldacres pioneered the use of pneumatic nozzle switching technology and boom recirculation in Australia more than a decade ago. In that time this technology has become the standard method for reducing chemical waste. The pneumatic nozzle switching replaces traditional boom section valves to control water flow to the nozzles, with the trend moving to wider booms in conjunction with greater number of spray sections meant that the traditional system simply became “to busy“ with the amount of hoses on the boom required. The Goldacres RapdiFire and RapidFlow system uses a single common feed spray line with the nozzles switching on and off using a number of small pneumatic hoses.
The result is significantly reduced amount of spray hoses, reduced volume of chemical in the boom lines, quick on / off times for the nozzle, easy to reconfigure section spray widths and number of sections and of course the ability to flush the spray line back to tank without the need to physically spray on the ground.
Nozzle technology has advanced in leaps and bounds over the years and a strong emphasis on drift control has influenced many nozzle designs, including air induction (AI) technology
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. To overcome this Goldacres offer a 3 tier system (3TS) which effectively gives the driver a much wider operating band whilst still maintaining
Over the last several years there has been a greater shift to precision farming technologies, such as auto steering and automatic boom section control. Both of these technologies are aimed at reducing spray overlaps and unsprayed areas, the former potentially causing crop burning and overuse of chemical. Depending on the field size and shape the wastage can be quite substantial. Goldacres have developed these practices further by introducing RapidFire air controlled nozzle shut off capability.
Traditional systems use motorised boom section valves to control water flow to the nozzles. Wider booms in conjunction with increased number of spray sections means substantial amount of plumbing is required, thus increasing the delay in spray on and off times. In addition, the further the nozzle is from the centre of the boom the longer the delay becomes. RapidFire overcomes these problems by putting the switching capability right at the nozzle.
Small air lines at each nozzle switch the flow on and off in a fraction of a second, and move evenly across the boom width. Boom line plumbing is also greatly reduced, which quickens line priming and flushing as well as simplifies plumbing.
RapidFlow boom recirculation
RapidFlow boom recirculation 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.
When your sprayer is sitting idle being reloaded with water and chemical it’s not making you money. That’s why Goldacres fit filling solutions that minimise the reload time to get you back in the paddock sooner.
The G4V Crop Cruiser has been designed and built with all the best fully integrated water and chemical transfer systems. This allows the sprayer to be reloaded quickly, safely and efficiently.
Central to the G4V’s fluid system is the ARAG MP400 multistage centrifugal pump. The pump is constructed using five impellors mounted to a common shaft which provides a more linear flow over a wide pressure range. The pump is rated to 400 l/min at 8 bar pressure. RPM sensor and oversize suction filter means the operator can be confident that adequate pump performance is being achieved.
EZ Control Station
Todays tough OH&S requirements are there to ensure everyone finishes the day like they started, safe and well. At Goldacres we not only take care of our own employees, but we ensure operators of our products are also looked after. The G4V features an all new EZ control operator station with well laid out colour coded connection points and valves at correct working heights, 70L hand wash tank and a wash down gun for rinsing out empty containers and fill station areas. External switches with protective covers allow the operator to switch on functions like the fill, chemical transfer and spray pump, external lighting, wash down gun and switch the suction between the main or 300L rinse tank.
Transfer water into the sprayer quickly and conveniently using the integrated 3” self priming centrifugal fill pump. The pump is plumbed from the fill point to the tank using 3” hose with minimal restrictions, this allows fill rates of up to 700 l/min. Because the fill pump is fully integrated through the EZ control station the water can be distributed to not only the main tank but also rinse water tank, main tank flush sprinklers, induction hopper flush and micromatic coupler
SuperFlow Chemical Induction Hopper
The SuperFlow 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 60L capacity with both drum and internal rinsing capabilities. The high flow 2” venturi is mounted at the base of the hopper which draws the chemical into the water stream at that point, minimising the chance of blockages.
Liquid chemical Transfer Systems
The G4V is equipped with two types of chemical transfer systems. Venturi and electric
When large quantities of neat chemical need to be transferred into the sprayer from either a 1000L intermediate bulk container (IBC), 110L enviro drum or just a standard 20L drum then the chemical enviro drum coupler or venturi probe can be used. This connection point uses a venturi mounted in the top of the tank to create a vacuum to draw the chemical straight in. At no stage does the neat chemical come into contact with any pumps
If precise amounts of chemical need to be measured into the sprayer then this can be achieved using the on board electric 12 volt transfer pump. This pump is plumbed directly to the 60L super flow induction hopper where the chemical volume can be measured. Once the desired volume is met then the chemical can be transferred to the main tank using the venturi at the base of the hopper.
Ease of transport
Whether you are spraying in the field or driving down the road, uninterrupted vision around the sprayer is essential for the safety of you and others.
Features like the flat folding boom wings so the operator’s line of sight is uninterrupted. Adjustable side mirrors provide a clear view of the road behind. Compact folded booms provides the operator with easy access to the cabin yet brings the overall transport width down to under 3.5m*, eliminating the need for an escort vehicle. Internal wet disc brakes fitted as standard if the unthinkable should happen. LED daytime running lamps, turn indicators, projector style halogen head lights and rotating warning beacons round out the package. The G4V Crop Cruiser really is one for the road.
