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).
