Configuring wide area nozzles
Wide area nozzles are nozzles fitted to the outer edge of the boom. They can spray further than the
normal nozzles.
Wide area nozzles and corner nozzles cannot be used at the same time.
Determining the spray range of the wide area nozzles
The spray range of a wide area nozzle is considered by the job computer to be the spray range of
several normal nozzles.
How many nozzles this is exactly depends on the spray range of the nozzles and the spray range of
the wide area nozzle.
A field sprayer is configured as follows:
Working width: 18 m
Total number of normal nozzles: 36
Spray range of the wide area nozzles: 2 m
Spray range of a normal nozzle: 18 m 36 nozzles = 50 cm per nozzle
The spray range of the wide area nozzles corresponds to the spray range of four normal nozzles:
200(cm) : 50(cm) = 4
