4.3 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.
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 via the 3 point linkage
and the rear roll linkage.

The standard Category 3 linkage at the front
of the Simba X-Press also has the ability to
fit Category 2 tractor linkages by reversing
the upper and lower link pins in their respec-
tive positions.

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.
