Operating Instructions
4.5 Double Disc Roller
The standard DD600 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.
The DD roll can be positioned at the rear of
the machine (rear roll) or between the tine
beam and rear disc gang (mid-roll).
4. Adjustment / Operation
4.4 Coulter Coverer
The coulter coverers are located at the ends
of the front disc gangs. These units are
designed to stop the throw of soil beyond the
cultivating width of the machine. The coverer
on the right hand side of the machine has a
transport and work setting. To change
between the two, the collar should be lifted
and the coverer arm rotated. The collar can
then be lowered to lock the arm in position
(see Fig. 4.04 below).
