4.2 Disc Units
The Simba X-Press features two rows of
discs which chop and mix the crop residue.
A disc spacing of 250mm ensures a fine
tilth and being arranged in a symmetrical
format around the centre line of the machine,
crabbing is eliminated, leaving the machine
to pull straight making the most efficient use
of the power available.
The discs fitted to the Simba X-Press 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 simply via shimmed
adjusters. All this is achieved without
compromise to consolidation.
A level, evenly cultivated finish is maintained
by adjusting the balance of soil throw
between the front and rear disc.
4. Adjustment / Operation
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.
The centre disc unit can be adjusted
independently of all other disc units to
ensure a level finish across the machine
width.
