NOTE: In Automatic control mode, the Hawkeye® 2 nozzle control system will adjust the system to maintain
the optimal application coverage within the operational ranges provided in the Tip Selection and
Application Speed Guide section on page 76.
CAUSES OF SKIPS USING HAWKEYE® 2 NOZZLE CONTROL
Operating the Hawkeye® 2 nozzle control system at or outside of the recommended operational ranges may
result in under-application or banding.
FOR EXAMPLE:
Under-application or horizontal banding may be observed if the operator from the previous example were to
toggle the application mode from Automatic to Manual and then increase the application speed from 15 mph
[24.1 kph] to 22 mph [35.4 kph] without manually increasing the nozzle control valve duty cycle.
