To convert 3-Row into 2-Row with Recapture.
Safety - this task is best done in controlled
conditions, using an appropriate lifting device.
It’s possible to convert the early season 2-row sprayer with
Recapture into a 3-row full coverage sprayer.
Sprayers ordered to this specification are supplied with
a double purpose Hanger (right hand version shown)
which makes it easier to change the 3rd-row fans or
boom Recapture assembly in and out without the need for
changing the Hanger.
Screen removal or installation is similar to the above
section.
To install / uninstall the 3rd-row fan is a little more
complicated as the hydraulics need to be reconfigured.
Be well prepared as some hydraulic oil spillage is likely.
Don’t forget to top up the hydraulic oil when finished.
• Disconnect the 3rd-row spray lines at the boom arm
where it changes from supply lines to individual spray
ring feeds, plug and leave the main hose in place on
the boom.
• When removing the 3rd-row fan frame its
recommended to trace the hydraulic hoses back to the
main hydraulic block (the 3rd row hoses should be
bundled separate to the others) and disconnected at
the block. Plug all exposed connections. The reverse
for reconnection.
• The oil supply will likely require reconfiguration.
At the time of printing several options exist – please
contact Technical Support staff for further details.
Controller configuration will also need changing.
See Tech Support.
RECAPTURE - OPERATIONAL TIPS
• Courser droplets work best for maximum recapture
rates. Hollowcone 40 degree nozzles are
recommended as a “standard” option. Dual spray
rings allow operators to use one of the spray rings as
a specialist nozzle ring for early season / Recapture.
Spraying should always be done in conjunction with
an agronomist.
• Keep the screens & trough clean and flushed. Much
easier to keep clean after each spray than to clean out
dried grunge at a later stage. If the sprayer is exposed
to the weather, rain can quickly fill the capture troughs.
•
For maximum efficiency always ensure the spray plumes
are directed towards the recapture screens, ideally just
forward of centre (to account for travel speed). See
pages 38 - 40 for adjustment detail. For best alignment
use the main boom arm fully open and adjust the slide
(and Push pull rod) to match row width.
• For row spacings less than 2.7m the “bus stops” may
clash whilst parking. As the need for the “awnings”
diminishes with narrower plantings, it’s more practical
to take one of them off, preferably the boom side.
• Consider turning off the recovery system and run
recaptured spray to waste if you suspect that the spray
is being contaminated with dust, weed seeds or other
foreign material.
• It’s recommended that canopies that are already
wet with dew or contain moisture should not be
sprayed / recaptured.
•
Be especially vigilant of keeping the Recapture filters
clean.
In some applications, especially when using 4 venturi may
require an anti foaming agent.
Inside the tank, each venturi has a hose extension which
terminates at different lengths (to minimise foaming). Note,
the venturi’s require a head of water to work
reliably
hence the effectiveness of the Recapture venturi
system will diminish as the main tank level drops.
