Operating Instructions
4.6 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 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
Standard Wing
P09060
 Maximum soil disturbance with mini-
mum draft requirement under normal
circumstances.
 Wing angle reduces wear rates on leg.
Extra Lift Wing
P10392
 Increased lift height and rake angle
creates greater soil disturbance on
all soil types especially in moister
conditions.
 Lower relative distance between
edge of wing and point reduces draft
requirement.
 Has ability to work at lower depths with
no decrease in soil disturbance or risk
of smear.
Extra Wide Wing
P10411
 Improved lateral shatter in moist/wet
soils, or non-cohesive soils.
 Ideal for deep vegetable applications
under light/medium soils.
