Farmers looking to increase precision
during spraying can do so with a product
from John Deere.
The ExactApply nozzle control system is available as
a factory option or aftermarket upgrade on R Series
sprayers and can bring multiple benefits to producers.
Its pulse with modulation (PWM) technology allows for
flow rate alteration across the width of a spray boom.
“We get a more uniform and even dose across the
width of the boom, so we don’t get those herbicide
carryover issues (and) we don’t have the over- and
under-applying issues in the corners of our fields,” said
Nick Fleitz
, a John Deere representative.
Another function included with ExactApply is the
nozzle switching function.
This allows operators to choose between two pre-
positioned nozzles from the cab for smaller or larger
droplets.
In addition, ExactApply allows operators to have
individual nozzle control.
Operators can use this feature to adjust which nozzles
are applying product at the appropriate times.
“Instead of having (up to) 10 nozzles working in
concert, we’re putting our individual sections in 15- or
20-inch spacings,” Fleitz said. “Our resolution is better
in the field and that can provide time and money
savings.”
Another benefit of ExactApply is application uniformity.
A sprayer without this system uses a pressure and
flow-based rate control.
“If we double our ground speed, we have to quadruple
our pressure to maintain that consistent output,”
Fleitz said, adding this could lead to over- and under-
applying.
ExactApply makes those changes almost
instantaneously.
“It’s much more responsive and helps us maintain a
constant pressure so our droplet size remains much
more consistent,” he said.
