WEEDIT TRAILED SPRAYERS
RESISTANT WEED STRATEGY
WEED-IT sprays on average five to 20% of the paddock depending on weed populations, enabling the use of chemicals from other family groups that are normally considered to be too expensive for a blanket application. This also allows growers and agronomists to develop long term herbicide resistance strategies.
SUPERIOR MODE OF DETECTION
WEED-IT’s near infrared technology only detects the chlorophyll present in living plants sending a quick response to the nozzles which release the spray onto the weed. This superior mode of detection allows for faster travel speeds and the ability to target even smaller weeds. WEED-IT improves at night because there is no interference from sunlight and weeds are often less stressed meaning the reaction to active chlorophyll is greater.
Changes in background conditions such as soil type and stubble are not a problem for WEED-IT's auto-calibration system. The WEED-IT is not affected by changes in background conditions because it is only measuring active chlorophyll. For the operator this means even better targeting of small grasses.
The WEED-IT operating system utilises two speed sensors to automatically calculate and adjust the reaction time of the nozzles during cornering. This ensures the chemical hits the target accurately every time – regardless of boom tip speed.
CROPLANDS CONTOUR FOLLOWING BOOM
Better boom height control = better detection + better kill
Croplands' heavy duty hydraulic fold 24 metre and 36 metre trailing contour following booms are 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 accuratelyas 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 WEED-IT. 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.
IN-CAB HYDRAULIC FOLDING BOOM
The boom is hydraulically controlled from the cab, to allow for quick and effortless folding and unfolding of the boom, from transport position to field operation.
SENSOR AND NOZZLE PLACEMENT
WEED-IT sensors are placed every 1 metre across the boom and control 4 nozzles (individually) on 25cm spacings. Benefits from this design are less weight due to less sensors and a smaller spray footprint when a weed is sprayed. This set-up provides great savings on chemical. The nozzle spacing of 25cm also allows for better penetration in stubble with less shading of small grasses.
SENSOR SPACING FOR ROW CROP SPRAYING
Traditionally WEED-IT sensors are positioned at 1 metre spacings along the length of the boom. This spacing can be adapted to 40 inch to meet the needs of row cropping or matching tillage equipment based on imperial measurements. Regardless of sensor spacing, there are four nozzles per sensor positioned at 25cm spacings. Close nozzle spacings are a major advantage in penetrating heavy 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. Full 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 full 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.
ENHANCED ELECTRICAL SYSTEM
Weed detection systems place large demands on electrical supplies. The WEED-IT overcomes this issue by running at 48 volts. This not only gives superior solenoid operation but current draw is 4 times less than other weed detection equipment using 12 volt systems. Faster solenoid operation also means quicker spraying speeds in the paddock.
IN CAB MONITOR AND CONTROLLER
The easy to use intelligent display provides constant monitoring of solenoid and sensor operation, with malfunctions or errors reported on screen – including warnings for low pressure, sensor faults and voltage. The smart design allows for easy fault identification and greatly increases productivity as the requirement to visually check and monitor the machine is dramatically reduced.
The display allows for sensitivity adjustments from the easy to use menu. The controller monitors increased boom speeds on corners and automatically adjusts response times to ensure the nozzle hits the target. This monitor also keeps record of nozzle activation, chemical use and sensor history.
