4.6 Double Disc Roller
The standard DD600/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 rear DD roller carries a proportion of the
machine’s weight to ensure consolidation. It
also regulates the depth of the machine. The
corrugated surface left by the roller is
weatherproof both for wet or dry situations.
4. Adjustment / Operation
4.5 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 re-
maining clods passing between the leaves
into the path of the press rings.
4.7 Out-Rigger Wheels
The Out-Rigger units support the wing tips in
work ensuring a level soil finish. The out-Rig-
ger units also support and lock the wings dur-
ing road transport.
