Hardi Australia is adding the advanced H-Select nozzle control technology as an option for its Commander trailed sprayer.
Previously available on self-propelled Rubicon and Saritor 62 Active machines, H-Select nozzle control technology uses 4-head nozzle bodies arrayed in individual boom sections.
An autonomous controller monitors each boom section's speed against the set spray rate, then selects nozzle heads rapidly and precisely in order to achieve consistent spray delivery.
"Placement or deposition of chemical is a significant determinant of spray efficacy," Hardi Australia CEO Bill Franklin said.
"In other words, predictably getting the right amount of chemical in the right place is what spraying science is all about. Achieving that with reliability is the holy grail for sprayer hardware.
"This is precisely why we have developed H-Select - to bring this extra precision and efficiency to our sprayers."
Hardi Australia product manager Steve Lancaster said offering H-Select on the Hardi Commander represented the next leap forward for the trailed sprayer segment.
"Adding highly advanced H-Select application technology to the Commander brings unrivalled precision and efficiency to the capacity and operating efficiency it is known for."
He said unlike pressure adjusted systems, which affected fluid velocity and therefore nozzle performance, the way H-Select switched between multiple nozzles meant the flow rate can be continually adjusted without compromising the size or speed of the droplets produced.
Droplet consistency was critical to effective crop penetration and drift control.
H-Select was also free from the boom size limitations that constrained other nozzle switching technologies and had been field-proven on Hardi 48.5 metre and even 54m booms.
ISOBUS integration meant H-Select operators could use the in-cab control screen to set and adjust their target droplet size on the go to suit changes in the crop, coverage rate and spraying conditions.
Hardi Australia will deliver the first Commander equipped with H-Select to Young, NSW, later this year.
