Operating Instructions
4.4 DD Light Roller
The DD Light roller is made up of individual
Double Disc (patented) Ring segments.
The DD Light roll is 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 rear DD Light roller carries a proportion of
the machine’s weight to ensure consolidation.
It also regulates the depth of the disc units.
The corrugated surface left by the roller is
weatherproof both for wet or dry situations.

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.
