16 Operators Manual
4.6 Aqueel 2 Roller
The Aqueel 2 is a rubber, specialist self-
cleaning tyre which leaves a patterned
surface profile consisting of conical
indentations. This is designed to combat
surface water movement and wind erosion in
the field. The benefit of Aqueeled ground
(reservoir tillage) is gained on light, easy
working soils that can slump or compact.
4.7 Work Settings
In practice it is possible to use a DD or
Aqueel roller on ground conditions that
are unsuitable to achieve the desired effect,
and it is usually possible to operate such
rollers without regular blockage under such
unsuitable conditions, assuming that the roll
assemblies are tight, the scrapers correctly
adjusted and rings smooth. As such,
especially under wet conditions, it is
advisable to check on the cultivation effect of
the machine fitted with such rollers, as these
normally do not limit the machines effective
use.
The machine can be lifted clear of the ground
for headland turns if the tine cultivation effect
is not needed. Generally, when being used as
a straw rake keep the machine in its working
setting at all times to maximise the straw
levelling effect.
If straw builds up excessively, tilt rearwards
slightly to allow the straw to be spread out
over the field. It is normal for straw to build up
and diminish as the process of evening up
the levels of residue occurs.
Often heaps on the headlands will cause a
temporary blockage but this will be lost down
the field, achieving the desired effect.
Excessively tight turning could
lead to damage of the tine
components!.
Avoid sections of
the machine going rearwards at all costs
otherwise tine breakage will occur.
4.7.1 Tine adjustment and setting
The rake tines can be adjusted for pitch
according to conditions. As a general guide,
the steeper the tine the more aggressive the
cultivation and raking effect.
Avoid setting the tines too far tips
forwards that they contact the
main axle wheels when folding.
It is normal to set the tine depth and straw
holding capacity by the rear roller. This allows
for tine angle to be set for the desired
cultivating effect.
If straw blocks regularly, initially raise the
tines by tilting the rake rearwards slightly on
the roller. If additional clearing is needed,
increase the rake angle of the tines (angle
tips rearwards).
