4. Adjustment / Operation
4.2 Double Disc Roller
The standard DD700 roller is made up of
individual Double Disc (patented) Ring
segments.
The DD rings are designed to consolidate
the soil whilst cutting and crushing any clods.
Even in heavy, wet soils it can easily be
operated with minimal blockages occurring.
The DD roller carries a proportion of the
machine’s weight to ensure consolidation.
The corrugated surface left by the roller is
weatherproof both for wet or dry situations.

4.3 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.

4.4 Levelling Boards
The action of the sprung leaf type levelling
boards is to carry and drop soil to level in
front of the press rings, to rub clod against
clod for additional soil breakdown, to force
clods down into the soil profile and to present
remaining clods passing between the leaves
into the row of press rings.
The levelling boards are set using shims in
the levelling board cylinders. During work,
these cylinders should be retracted onto the
shims but can be extended to release any
soil / trash build up.
