Key Features

  • Offset design – operator walking beside the sprayed area, not through it.
  • Adjustable nozzle distance to operator – whole nozzle configuration can be ‘pushed’ further away from operator. Very useful when spraying taller crops and for overall reduction in operator exposure. Nozzles can also be rotated 90 or 180 degrees to enable easier spraying of tall crops.
  • Extremely lightweight design – 2.7 kg boom weight plus 1 and 1.5 kg counterweight options.
  • Flexible counterweight options – only use the counterweight required. Eg 1 kg weight required for standard 4 nozzle configuration to perfectly balance the boom.
  • High quality reliable fittings – Brass spraying systems trigger with extended handle, Norgren liquid regulator, glycerine gauge, spraying systems nozzle bodies and pneuflex pneumatic fittings.
  • 3k twill weave carbon fibre boom lengths.
  • Aluminium handle design with custom rubber grips.
  • Minimal plumbing design – 8 and 6 mm tubing minimises the spray solution required but can still spray 500 L/ha at a comfortable walking speed (larger sized nozzles required eg 03’s).
  • Includes Air Induction Flat Fan 01 nozzles – Run Brolga at 250 kpa and a comfortable walking speed will acheive 100 L/ha – refer to User Guide included for calibration guide and example calculations to determine walking speed.
  • Clear polyurethane tubing – easy to see next treatment running through boom or build-up of residue.
  • Superior plumbing design – all nozzle outputs are the same (within 3%) and all nozzles produce spray pattern immediately once trigger is activated (regardless of using 4 or 6 nozzles), once the system is primed.
  • Collapsible compact design – hinged joints so no need to disconnect tubing. Allows set-up and pack down in seconds. 
  • Nozzle guard – clips onto the end of the nozzle section and keeps your nozzles out of the dirt.
