CAUSES OF SKIPS USING HAWKEYE NOZZLE CONTROL
Operating the Hawkeye 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 km/h] to 22 mph [35.4 km/h] without manually increasing the nozzle control valve duty cycle.
