4.7 Work Settings
Optimum performance has been found to
be achieved when the DD roll rings have
worn away the painted finish leaving a
smooth shiny surface. When the DD rings
are new or rusty, soil may tend to pick up on
the surface and blockage may occur, this
will reduce when the rings are shiny again.
The DTX AR should be run with the
chassis level to slightly tail low. In practice
it is possible to use the DTX AR on ground
conditions that are unsuitable to achieve
the desired effect, and it is usually possible
to operate the DD roll without regular
blockage under such unsuitable conditions,
assuming that the roll assemblies are tight,
the scrapers correctly adjusted and rings
smooth. As such, especially under wet
conditions, it is advisable to check on the
cultivation effect of the DTX AR.
The DTX AR should be lifted fully clear of
the ground for all headland turns. Turning
with the tines, disc units or roller on the
ground could lead to damage of these
components.
In work, the tractor lower link arms
should be run in position control with draft
introduced if required.
4.8 General Rules when
Setting the Simba DTX AR
 The lighter the land conditions the
less the disc angle required and the
forward speed can be increased.
 The wetter the land conditions the less
the disc angle required and the forward
speed will need to be decreased.
 Heavier land will require more of a disc
angle and a slower forward speed.
 The more the trash the less the angle
on the discs and forward speed will
have to be decreased.
 On ploughed land reduce the disc
angle to give a cutting/chopping
action.
 In hard conditions increase the disc
angle to increase penetration.
