Operating Instructions
The SIMBA DTX is an amalgamation of
time proven, successful Simba designed
components brought together to form this
important development. The DTX provides
a one pass mix with a ssured layer at disc
depth for through drainage and root access
to lower horizons. This enables rapid
drainage and access after rain, creating
a greater effective capacity for moisture
compared to ploughing for the same
effective total depth of cultivation.
In principle, the machine is a subsoiler
followed by an offset disc designed for
low draft, high speed operations. The
addition of a rear mounted roll enables
effective cultivation in one pass. The key
to the DTX’s success are the tines which
maintain shatter across the full width of
cultivation. This is followed by the discs
that cultivate the soil surface and minimise
and clod formation. Finally, the rear roll
consolidates the surface, cracks any clods
and rms the soil prole after the rear discs
complete mixing to depth. This starts the
‘top down’ cultivation process, retaining
weathered tilth in the surface level for stale
seedbed purposes. The corrugated top
and shattered lower horizons are left fully
weatherproof to any conditions between
cultivation and drilling whilst retaining
moisture below the surface for rapid straw
breakdown and optimum establishment of
the next crop.

4.2 3 Point Linkage
The DTX 300 is tted with a standard
Category 3 linkage at the front of the
machine.
Fig. 4.02: 3 Point Linkage
4.3 Tines
The DTX is tted with either Pro-Lift or
LD (Low Disturbance) tines. The tines are
arranged in a staggered formation to give
lower draft requirements and the ability to
work progressively deeper. The tines are
spaced at 400mm. Each tine is shear bolt
protected. Tine depth is achieved by moving
the tines up and down in the adjustable
clamps.
Different wings are available to suit the soil
conditions and optimise the performance
of the machine.
4.3.1 Pro-Lift Wings
Standard Wing
P09060
Maximum soil disturbance with
minimum draft requirement under
normal circumstances.
Wing angle reduces wear rates on
leg.
Extra Lift Wing
P10392
Increased lift height and rake angle
creates greater soil disturbance on
all soil types especially in moister
conditions.
Lower relative distance between
edge of wing and point reduces draft
requirement.
Has ability to work at lower depths
with no decrease in soil disturbance
or risk of smear.

Operating Instructions
Extra Wide Wing
P10411
Improved lateral shatter in moist/wet
soils, or non-cohesive soils.
Ideal for deep vegetable applications
under light/medium soils.
4. Adjustment / Operation
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 ne tilth.
The discs tted 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.
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.
A level, evenly cultivated nish 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 ex up
and down in work.
Fig. 4.05: DD Lite Roller
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.
Fig. 4.04: Discs
The rear DD Lite roller carries a proportion
of the machine’s weight to ensure
consolidation. It also regulates the depth

21DTX
Operating Instructions
4. Adjustment / Operation
4.7 Work Settings
Optimum performance has been found to
be achieved when the DD roll rings have
worn away the painted nish 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 should be run with the chassis level
to slightly tail low. In practice it is possible
to use the DTX 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.
4.8 General Rules when
Setting the DTX
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.
The DTX 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.
In hard conditions increase the disc
angle to increase penetration.

4.10 Adjusting Depth
To change the working depth it is advisable
to lift the machine clear of the ground so
that the rear roll linkage becomes loose.
Move the position of the depth pins to
change the depth.
Fig. 4.06: Roll Linkage
When the depth has been altered, lower the
machine into work and check operation. If
the depth change has been signicant then
other setting could be affected. This could
be chassis pitch (front to rear) and disc
angle for the given depth.

A small amount of cultivation, eg. a 20
metre run, should be carried out before
altering these settings to check whether
they are now suitable for the cultivation
effect required. These settings should be
addressed immediately to prevent too
much work being carried out.

4.11 TurboJet
The SL can be tted with an optional
TurboJet Oil Seed Rape applicator. The
Turbo Jet is an air seeder unit which uses
two fans to deliver seed behind the rear roll
in work.
The TurboJet can be operated from the cab
of the tractor using an advanced computer
control module, the RDS Wizard System.

4.13 Parking the machine
In order to avoid damage as a result of
moisture, the machine should be parked, if
possible, indoors or under cover.
When manoeuvring the
machine, pay attention to your
surroundings. Ensure that
nobody is in the manoeuvring
area (watch for children!).
Park the machine on level and solid
ground.
Lower the machine onto the parking
stands / tines ensuring that it is stable.
Remove the toplink and lower the link
arms so that pins can be removed.
Switch off the tractor.
4.14 Checks
The working quality depends on the
adjustments and checks made prior to and
during work, as well as on regular servicing
and maintenance of the machine.
4.12 Work Instructions
Driving speed
The DTX 300 can be driven at speeds of up
to 12 km/h.
This depends on the eld conditions (type
of soil, surface trash, etc.).
Drive more slowly if the conditions are
difcult or a rmer nish is required.
Turning:
Before turning, the machine should
be lifted out of work while driving.
Likewise, it should lowered back
into work once the turn has been
completed.
Before beginning work it is therefore
important to carry out any necessary
servicing and to lubricate the machine as
required.
Checks prior to, and during
work:
Is the machine correctly hitched up
and the coupling device locked?
Is the machine in a level operating
position and the working depth set
correctly?
Working Elements
Are the discs and other cultivation
tools in a serviceable condition?
Are the scrapers still operable, so that
the rolls do not jam?

5. Servicing and Maintenance
5.0 Servicing and
Maintenance
Follow the safety instructions for
servicing and maintenance.
5.1 Servicing
Your machine has been designed and
constructed for maximum performance,
operational efciency and operator
friendliness under a wide variety of
operating conditions.
Prior to delivery, your machine has
been checked at the factory and by your
authorised dealer to ensure that you
receive a machine in optimum condition.
To ensure trouble-free operation,
it is important that servicing and
maintenance work is performed at
the recommended intervals.
Regularly examine hub caps,
seals, shear and pivot bolts and
all tracking bolts for tightness
and effectiveness twice weekly
or every 50 working hours
(whichever is more frequent).
5.3.1 Tightening Disc Hubs
1 Ensure that the bearing seal is in the
correct orientation when replacing /
assembling components.
2 Ensure that the stub axle is free from
dirt and the nut and outer bearing can
easily slide on it.
3 Tighten the crown nut with a hand
spanner (a torque wrench is not
req uired) while turning th e hub
clockwise until the bearing drags
slightly (you feel the hub turning
heavily). Some resistance will be due
to friction from the seal.
5.2 Cleaning
In order to ensure that the machine is
always in operating condition and to
achieve optimum performance, perform
the cleaning and servicing work at regular
intervals.
Avoid cleaning the roll / disc bearings with
a high- pressure hose or a direct water jet.
The housing, screwed connections and
ball bearings are not watertight.
5.3 Disc Hub Maintenance
Grease every disc hub until
grease shows from the seals
according to the lubricating
intervals outlined on page 28.
Check disc hubs regularly for
tightness.
4 Turn back the crown nut to the next
locking position. Even if the tightening
of the nut has reached an exact xing
position, turn it back.
5 Insert the retaining pin.
6 Try to shake/rock the outer edge of the
hub/spindle: play of 0.1 / 0.2mm will
not reduce the bearings’ life and, in
addition, prevents overheating. If the
adjustment is correct the hub should
turn freely with the only friction being
from the seal.

5.4.1 Bearing Seals
It is important when replacing the labyrinth
type bearing seals in disc hubs that the
seal is tted the right way round. The
chamfered lip side should be at the outside
of the bearing housing, nearest the disc
arm (see Fig. 5.02). This chamfered lip
prevents dirt ingress into the housing and
also allows grease to be ushed though
when greasing.

5.4 DD Lite Roll
The spacers and rings on the DD Lite Roll
are held under tension by the end plates at
the outer ends of the roll tube.
Specialist equipment is required
for the disassembly of DD Lite
rollers. Please consult your
dealer under any circumstances
that require disassembly of these
rollers.
Maintenance of these rollers is limited
to yearly/end of season greasing of the
bearings and regular inspection to ensure
the assemblies are tight, and scrapers are
correctly set.
The scraper is intended to clear
dirt from blocking between
adjacent DD rings. If adjustment
to the scrapers is required ensure
that the scraper cannot contact the
spacer even under load. Regularly
inspect the spacers for signs of
wear and adjust any scrapers to
ensure no contact can be made.
5.5 Double Disc Axles
The axles on this roller are tensioned by the
main axle through the centre of the rings
and bearings.
Specialist equipment is required
for the disassembly of Double
Disc axles. Please consult your
dealer under any circumstances
that require disassembly of these
axles.
Maintenance of these rollers is limited to
daily greasing of the bearings to ush out
dirt, and regular inspection to ensure the
assemblies are tight, and scrapers are
correctly set. The axles can be tightened
provided the bearing pillar ‘U’ bolts are
loosened to avoid preloading the bearings
as they move sideways to each other.
Ensure the bearing pillars are re- tightened
to the mainframe after this.
5.6 Preparation for
Storage
If you need to store the machine for a longer
period, observe the following points:
• Park the machine undercover if possible.
• Protect the roll / discs against rust. If you
need to spray the implements with oil, use
light, biologically degradable oils, e.g. rape
oil.

Operating Instructions
5. Servicing and Maintenance
Cover any rubber sections before
using oil sprays. These sections
must not be oiled. Remove
any traces of oil with a suitable
cleaning agent.
5.7 Tines
When performing maintenance
work on tines extreme care
should be taken. Wear goggles
and gloves at at all times when
maintaining tines.
Safely support unfolded machine
in raised position using taps
and stands before attempting
maintenance work on tines.
Do not attempt to assist tting
tine points with a steel headed
hammer, this can lead to
splintering of the metal due to its
hardness, which can cause injury.
If tine tting requires assistance,
a copper/hide or plastic mallet
should be used.
5.8 Operator Support
If you have a problem, please contact your
dealer. They will endeavour to solve any
problems which may occur and provide you
with support at all times.
5.9 Maintenance
Intervals
Apart from daily maintenance, the
maintenance intervals are based on the
number of operating hours and time data.
Keep a record of your operating hours to
ensure that the specied maintenance
intervals are adhered to as closely as
possible.
Never use a machine that is due for
maintenance. Ensure that all deciencies
found during regular checks are remedied
immediately.
Avoid sharp-edged and pointed
parts (disc blades, etc.) when
working on the machine.
Place the machine on suitable
supports when working
underneath! Do not work under a
machine which is not supported!
On a new machine tighten all nuts and bolts
after 5 hours work and again after 15 hours.
This also applies to parts that have been
moved or replaced. After the initial 15 hours
of work a once a week check should be
sufcient depending on daily work rates.
In order to enable your dealer to deal with
problems as quickly as possible, it helps
if you can provide them with the following
data. Always state the:
• Customer Number
• Name and Address
• Machine Model
• Serial Number of Machine
• Date of Purchase and Operating Hours
• Type of Problem
