Hydraulic adjustment of the Convert brackets
Optionally the boom can be hydraulically adjusted from the tractor
cabin.
In that case let the above indicated friction pads be just as loos as it
allows the inner tube to slide in and out easily.
IRIS system setup
The IRIS application system is standard equipped with ceramic hollow
cone nozzles. Each drop leg holds 8 nozzles per drop leg. If a curtain
area of the canopy is not meant to be sprayed, a small valve is fi tted as
per two nozzles that allow turning of the spray mist. If only one nozzle is
needed in that area it is as well possible to fi t a blind cap.
In the valve A that allows the spray mist to pass on the nozzle, there is a
small no drip valve that secures when the main switch turns of the spray
mist, that all nozzles stops instantly, and do not spill on the ground.
The nozzles B are fi tted in an adjustable support, in order to angle them
forward accordingly to forward speed, and there by not loosing spray
mist behind the sprayer.
The air outlet has an indicator C that shows the angling of the air blade
E which are adjusted by pressing bottom D in, and then move up or
down the vanes E.
The air outlet in the lower part shall be orientated upwards to get the
spray mist penetrating from down and upwards. The upper spout shall
point downward in order to avoid drift. Those setting are accordingly to
grot hog the canopy, and adjustment is necessary during the season, as
the size of the canopy change.
In order to get the optimal cross fl ow eff ect and penetrate the canopy
the IRIS drop leg shall be set 10º , 15º , 20º or 30º forward, as indicated in
the adjustable part in the top of the drop leg. The forward angling is set
accordingly to forward speed while spraying.
