OPERATION MODES

®
The Hawkeye control system can be configured in several different modes to fit the application.

• Standard - The Hawkeye
common sprayer setting.
• Variable Pressure (VP) - This mode will control to a target-flow rate and target nozzle duty cycle by varying the
pressure. This is useful for scenarios where pressure is not a priority (i.e. fertilizer application).
• High Flow - This mode allows both a conventional nozzle and a Hawkeye
achieve higher flow rates.
• On/Off - The Hawkeye
not applying. This mode can be used with air induction tips and stream bars.
• Bypass (Conventional) - The Hawkeye
disabled. A secondary flow outlet must be made available at each tip.Flow Control
• Conventional flow control spray systems use a flowmeter to monitor the flow through the flow through the
system and adjust a control valve to maintain target application rate. This allows the operator to turn on and off
sections and change vehicle speeds while maintaining the desired application rate.

PRESSURE NOZZLE CONTROL

®
The Hawkeye nozzle control system provides the same spray pattern and coverage as conventional spray
systems. Pressure based nozzle control allows the operator to maintain the same target pressure and operate over
a larger application speed or flow range while maintaining droplet size. This may help manage spray drift and
allow the equipment to operate in higher winds. Better droplet control also provides more accurate field
application and better rate control at lower target flow rates than the flowmeter can detect.
TURN COMPENSATION
Conventional application systems provide a uniform rate across the boom or implement width. This functionality
works well in large field areas with straight swaths to ensure even coverage during application.
