Fig. 4.04: DD Light Roll
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.
4.5 Work Settings
Optimum performance has been found to
be achieved when the DD Light roll rings
have worn away the painted finish leaving
a smooth shiny surface. When the DD Light
rings are new or rusty, soil may tend to pick
up on the surface and blockage may occur,
this will reduce when the rings are shiny
again.
The Simba SL should be run with the
chassis level to slightly tail low. In practice
it is possible to use the Simba SL on ground
conditions that are unsuitable to achieve
the desired effect, and it is usually possible
to operate the DD Light roll 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 Simba SL.
The Simba SL should be lifted fully clear of
the ground on the transport wheels for all
headland turns. Turning with the disc units
or roller on the ground could lead to damage
of these components.
