WEEDit 4000 I 6000
CROPLANDS CONTOUR FOLLOWING BOOM
Heavy duty hydraulic fold 18 metre, 24 metre, 30 metre, 32 metre and 36 metre trailing contour-following booms, designed to handle Australia’s challenging broadacre farming conditions. Some models may have road transport speed limitations. The hydraulically steered inner boom wheels control the folding and unfolding of the boom, this is also a pivot point for the boom to contour follow. In total there are five different plains that the boom and sensors can operate at to mirror the contours as accurately as possible. The sensors will achieve the lowest possible spray rate per hectare and effectively target small grasses when the boom height is maintained, with only small variations in height. New responsive gas air ride suspension on all boom wheels is custom engineered for Croplands WEEDit. This helps to maximise sensor effectiveness by controlling compression and rebound to allow the sensor a smooth ride for superior detection. The responsive gas air ride suspension also absorbs vibration to reduce metal fatigue and improve longevity.
SENSOR SPACING AND ROW CROP SPRAYING
Traditionally WEEDit sensors are positioned at 1 metre spacings along the length of the boom. This spacing can be adapted to 40" to meet the needs of row cropping or matching tillage equipment based on imperial measurements. Regardless of sensor spacing, there are five nozzles per sensor positioned at 20cm spacings. Close nozzle spacings are a major advantage in penetrating stubbles such as sorghum and also minimising shading.
The standard 40 degree flat even fan nozzle provides a course droplet spectrum and provides great coverage for broad leaf weeds in a warm summer weed spraying environment. Cone nozzles can be used for larger targets where non systemic chemicals are used in a strategy to avoid the over use of glyphosate. The cone nozzle provides the advantage of spraying forwards and rearwards at an angle enhancing penetration. Full cone spray patterns aim for complete plant coverage. Coverage is king with contact chemicals.
IN-CAB HYDRAULIC FOLDING BOOM
Unlike other wheeled booms it is hydraulically controlled from the cab, to allow for quick and effortless folding and unfolding of the boom, from transport position to field operation
6000 OR 4000 LITRE MAIN TANK
Spot spraying sensors or optional blanket line can be run from the main tank, utilising the dual pumps simultaneously. As an example, a pre-emergent herbicide could be applied through the blanket line, while the spot spray sensors may be applying a knockdown herbicide to existing weeds.
1100 LITRE HOT TANK
Spot spraying sensors are run from the Hot Tank. A common strategy used to delay the onset of herbicide resistance is to use a more concentrated combination of chemicals for spot spraying. This is often referred to as the "hot mix” that becomes affordable when only spraying 10% of the paddock with the WEEDit system.
GAS AIR RIDE SUSPENSION
Featuring air-bags to control ride-height. The system utilises coil springs to provide fast and responsive ride for the sensors. The enhanced ride assists with detection of weeds on both compression and rebound, minimising metal fatigue across the machine.
CHASSIS AND AXLE
The chassis encompasses a simple robust design with safe platforms and handrails for ease of operation. It features a 2.2 metre axle track, optional 3 metre solid axle or 3 metre adjustable axle.
The WEEDit operating system utilises two speed sensors to automatically calculate and adjust the nozzle timing to ensure the chemical hits the target accurately every time regardless of boom tip speed.
HYDRAULIC DRIVE CENTRIFUGAL PUMP
The advantages of the 500 L/min centrifugal pump for spot spraying applications is that it can respond and deliver from zero to very high volumes almost instantly as required.
