21 DTX
Operating Instructions
Fig. 4.05: DD Lite Roller
4.4 Disc Units
The DTX features two rows of discs which
chop and mix the crop residue. A disc
spacing of 250mm ensures a fine tilth.
The discs fitted to the DTX are 500mm in
diameter (20”) and 6mm thick. They are
manufactured from heat treated chrome
boron steel which ensures excellent wear
resistance and enhanced working life.
Each disc is mounted on a Pro-Active
sprung leaf linked to a track rod system.
Gang angles can be varied with ease and
accuracy using a graduated adjuster.
Adjustable angling of the discs (between
10°-25°) ensures penetration and stubble
mixing are achieved in one pass. Working
depth can be varied via the 3 point linkage
and the rear roll linkage.
A level, evenly cultivated finish is maintained
by adjusting the balance of soil throw
between the front and rear disc.
Sprung Pro-Active leaves offer protection
against damage as well as offering a
degree of contour following as they flex up
and down in work.

4.5 DD Lite Roller
The DD Lite roller is made up of individual
Double Disc (patented) Ring segments.
The DD Lite 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 Lite 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.
4.6 DD600 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 Lite 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.
