Operating Instructions
1. Safety Data
1.2 Use for the Intended
Purpose
The SIMBA SL is built using the latest
technology and in accordance with the relevant recognised safety regulations. However,
risks of injury for the operator or third parties
and impairment of the machine or other
tangible assets can arise during use.
The machine is only to be operated when in
a technically perfect condition and for the
intended purpose, taking into consideration
safety and risks and following the Operating
Instructions. In particular, faults that can
impair safety are to be remedied
immediately.
Original parts and accessories from SIMBA
have been specially designed for this
machine. Spare parts and accessories not
supplied by us have not been tested or
authorised. Installation or use of non-original
SIMBA products may have a detrimental
effect on specific design features of the
machine and affect the safety of machine
operators and the machine itself. SIMBA will
accept no liability for damage resulting from
the use of non-original parts or accessories.
1.3 Operational Safety
The machine is to be put in operation only
after instruction has been provided by an
employee of the authorised dealer or an
employee of SIMBA. The “Machine
Registration” form is to be completed and
returned to SIMBA (failure to do so will affect
your warranty).
All protective and safety equipment, such
as removable protective equipment, must be
in place and functioning reliably before the
machine is put in use.
Check screws and bolts regularly for
tightness and retighten if necessary.
In the event of malfunctions, stop and
secure the machine immediately.
Ensure that any faults are remedied
immediately.
1.3.1 No Liability for
Consequential Damage
The SL has been manufactured by SIMBA
with great care. However, problems may still
occur when it is used for the intended purpose.
These may include:
The SIMBA SL is designed solely as a
cultivation implement. Use for any other
purpose, e.g., as a means of transport, will
be deemed to be improper use. SIMBA will
accept no liability for damage resulting from
improper use. The risk will be borne solely by
the operator.
• Worn wearing parts.
• Damage caused by external factors.
• Incorrect driving speeds.
• Incorrect setting of the unit (incorrect
attachment, non-adherence to the Setting
instructions).
Therefore, it is crucial to always
check your machine before and
during operation for correct
operation and adequate application
accuracy.
Compensation claims for damage which has
not occurred to the machine are excluded.
This includes any consequential damage
resulting from incorrect operation.

Operating Instructions
1. Safety Data
1.4 Road Traffic Safety
When driving on public roads, tracks and
areas, it is important to observe the relevant
road traffic laws as well as the specific
regulations relating to this machine.
Pay attention to the permitted axle
loads, tyre carrying capacity, and
total weight in order to maintain
adequate braking and steerability
(these figures are shown on the
serial plate).
Passengers on the machine are
strictly forbidden!
Max. road transport speed 16mph
(25km/h).
1.5 Accident Prevention
In addition to the Operating Instructions, it is
important to observe the accident prevention
regulations specified by agricultural trade
associations.
1.5.1 Hitching-up the
machine
There is a risk of injury when hitching/
unhitching the machine. Observe the following:
• Secure the machine against rolling.
• Take special care when reversing the tractor!
• There is a risk of being crushed between
the machine and the tractor!
• Park the machine on firm, level ground.
1.5.2 On the Hydraulic
System
Do not connect the hydraulic lines to the tractor
until both hydraulic systems (machine and
tractor) are depressurised (see section 5.7
on page 29).
Any hydraulic system containing an
accumulator can remain under
pressure permanently (even after
following manual depressurisation
procedures with a tractor /
implement combination). It is
therefore important to check all
lines, pipes, and screw
connections regularly for leaks and
any recognisable external
damage.
The hydraulic circuit contains
specialised fittings which should
not be tampered with under any
circumstances. Do not attempt to
modify hose routings or hose
clamping arrangements, doing so
my cause serious damage to the
machine and/or injury.
Only use appropriate aids when checking for
leaks. Repair any damage immediately.
Spurting oil can cause injuries and fires!
In case of injury, contact a doctor immediately.
The socket and plugs for the hydraulic
connections between the tractor and the
machine should be colour-coded in order to
avoid incorrect use.

2. Transportation / Installation
2.4 Hitching Up
2.4.1 Hitching up a Tractor
to the SL / Preparing for
Transport
When hitching-up the machine,
ensure that no-one is between the
tractor and the machine.
When the SL is parked for extended
periods of time it should ideally be
left in the unfolded, i.e. work position
for stability, safety and ease of
access for maintenance. However,
parking the SL in the folded position
(ensuring the transport lock is
engaged) is acceptable in the
normal course of operation.
Tractor Oil Flow Adjustment:
As a general rule the tractor oil flow
rate should be set in the lowest
setting before starting. This can then
be increased to allow the desired
rate of operation as applicable. This
will minimise excessive oil flow and
consequent power usage and heat
generation.
5. If the machine is already folded it is now
ready for transport. If the machine is
unfolded please refer to 2.5.2.
Ensure that the wing lock is engaged
correctly before transporting the
machine.
Fig. 2.01: Bar Coupler
1. Reverse the tractor up to the bar coupler
and engage the link arms.
2. Ensure the tractor hydraulics are
depressurised and in the locked or
closed (not float) setting. Ensure the
axle taps are closed.
3. Couple the hydraulic hoses to the tractor
ensuring that the two wing hoses
(yellow) are together and the lift cylinder
hoses (red) are together.
4. Raise the front of the machine and move
the parking stand to the work position.

Operating Instructions
The SIMBA SL is an amalgamation of time
proven, successful Simba designed
components brought together to form this
important development. The SL has been
designed and produced in conjunction with
the Simba ECOtillage™ system to provide a
one pass mix with a fissured 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 an offset disc with
Terra-Grip tines, designed for low draft, high
speed operations. The addition of a rear
mounted roll enables effective cultivation in
one pass. The leading set of disc blades
cultivate the top horizon, minimising clod
formation and reducing tine loadings and
blockage. This starts the ‘top down’
cultivation process, retaining weathered tilth
in the surface level for stale seedbed
purposes. The front row of discs is then
followed by tines or a second row of discs
depending upon the machine configuration.
The tines work to shatter at depth retaining
the surface intact to leave an ECOtillage
™
stale seedbed. This eliminates the problem
of ‘wet years’ in non-plough based terms. The
key to the SL’s success are the tines which
maintain shatter across the full width of
cultivation. The rear roll then consolidates the
surface, cracks any clods and firms the soil
profile after the rear gang completes mixing
to depth. 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 Disc Units
The SL 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 SL 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-Flex 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. All this is achieved
without compromise to consolidation.
4.3 Terra-Grip Tines
Terra-Grip tines have a robust, basic
construction and are suitable for all soil types.
The spring-loaded auto-reset system with a
500kg trip force on each tine prevents
damage to the tines and tine brackets.
When the auto reset system is activated an
initial progressive phase holds the tine in the
ground in a steady position until the trip point
is reached. In the subsequent spring
compression phase the tine is raised gently
and rapidly to a maxmum height of 230mm.
The tines can be fitted with a selection of points
depending on application and have 6 depth
settings in 25mm increments down to a
maximum working depth of 250mm..
A level, evenly cultivated finish is maintained
by adjusting the balance of soil throw between
the front and rear disc.
Sprung Pro-Flex leaves offer protection
against damage as well as offering a degree
of contour following as they flex up and down
in work.

4.4 DD Light Roller
The DD Light roller is made up of individual
Double Disc (patented) Ring segments.
The DD Light 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 Light 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.
4.5 Work Settings
Optimum performance has been found to be
achieved when the DD Light roll rings have
worn away the painted finish leaving a smooth
shiny surface. When the DD Light 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 SL should be run with the chassis level to
slightly tail low. In practice it is possible to use
the SL on ground conditions that are
unsuitable to achieve the desired effect, and
it is usually possible to operate the DD Light
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 SL.
Fig. 4.06: DD Light Roll
The SL should be lifted fully clear of the ground
on the transport wheels for all headland turns.
Turning with the disc units or roller on the
ground could lead to damage of these
components.
In work, the tractor link arms should be used
in conjunction with the rear roll to determine
working depth / pitch.

4.7 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. The
depth is changed by adding shims above and
below the collar on the depth control rod.
DEPTH CONTROL ROD
COLLAR
Fig. 4.07: Roll Linkage
When the depth has been altered, lower the
machine into work and check operation. If
the depth change has been significant then
other settings could be affected. This could
be chassis pitch (front to rear) and disc angle
for the given depth.
4.8 Work Instructions
Driving speed
The SL can be driven at speeds of up to 12
km/h.
This depends on the field conditions (type of
soil, surface trash, etc.).
Drive more slowly if the conditions are difficult
or a firmer finish is required.
Turning:
Before turning, the machine should
be eased fully out of work onto the
transport wheels while moving
forward. Likewise, it should eased
back into work once the turn has
been completed. Do not attempt to
turn the machine on the roll.
4.9 Parking the machine
In order to avoid damage as a result of
moisture, the machine should be parked, if
possible, indoors or under cover.
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
unsatisfactory work being carried out.
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.
• Raise the machine and lower the parking
stand.
• Lower the machine to the ground, ensuring
that it is stable.
When parking with the machine
unfolded, ensure that no load is
carried by the Terra-Grip tines.
This can lead to breakage of the
points.
• Disengage from the linkage and drive
forward slowly until the tractor is clear.
• Switch off the tractor.
• Disconnect hydraulic lines from the tractor.

4.10 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.
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?
• Have the hydraulic lines been connected
according to the colour coding?
• 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
Follow the safety instructions for
servicing and maintenance.
5.1 Servicing
Your machine has been designed and
constructed for maximum performance,
operational efficiency 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.
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.
Regularly examine hub caps, seals
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
required) while turning the hub
clockwise until the bearing drags slightly
(you feel the hub turning heavily). Some
resistance will be due to friction from the
seal.
4 Turn back the crown nut to the next
locking position. Even if the tightening
of the nut has reached an exact fixing
position, turn it back.
5 Insert the retaining pin.
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 31.
Check disc hubs regularly for
tightness.
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.

5.3.2 Bearing Seals
It is important when replacing the labyrinth
type bearing seals in disc hubs that the seal
is fitted 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
flushed though when greasing.

5.5 DD Light Roll
The spacers and rings on the DD Light 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 Light
rollers. Please consult your dealer
under any circumstances that
require disassembly of these
axles.
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.
5.6 Brakes & Wheel Hubs
The brakes should be tested before using for
the first time and after the first laden journey.
Tine maintenance should be
performed with the machine fully
raised and with all taps closed.
When working under the machine
ensure that the tractor handbrake
is on.
When changing points on TerraGrip tines extreme care should be
taken. Wear goggles at all times
when changing tine points.
Simba SL

Operating Instructions
Check that the road and parking
brakes operate and release
correctly before using the machine.
Check for hydraulic fluid and air
leaks.
Brake and hub maintenance and
servicing should be carried out by
an authorised Simba dealer.
5. Servicing and Maintenance
5.7 Hydraulics
A low oil flow should be used, i.e.,
tractor tickover or low flow
selected.
The wing circuit is controlled by an
overcentre valve contained within
the manifold block which positively
locks oil flow until pressurised by
the tractor. System pressure can
be retained in the circuit even after
depressurisation of the tractor
quick release couplings.
Exercise extreme care when
checking the valve or circuits, and
under no circumstances attempt
to adjust or loosen fittings without
prior reference to your authorised
Simba dealer, and detailed
maintenance instructions.
5.9 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.
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 and Serial Number
• Date of Purchase and Operating Hours
• Type of Problem
5.10 Maintenance
Intervals
Apart from daily maintenance, the
maintenance intervals are based on the
number of operating hours and time data.
The hydraulic circuit contains
specialised fittings which should
not be tampered with under any
circumstances. Do not attempt to
modify hose routings or hose
clamping arrangements, doing so
may cause serious damage to the
machine and/or injury.
5.8 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.
Cover any rubber sections before
using oil sprays. These sections
must not be oiled. Remove any
traces of oil with a suitable cleaning
agent.
Keep a record of your operating hours to
ensure that the specified maintenance
intervals are adhered to as closely as
possible.
Never use a machine that is due for
maintenance. Ensure that all deficiencies
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
sufficient depending on daily work rates.

5.13 Lubricating the
Machine
Please read the section entitled "Using
Lubricants" carefully before lubricating the
machine.
The machine must be lubricated regularly in
order for it to remain serviceable. Regular
lubrication also contributes towards extending
the service life of your machine.
The recommended lubricating intervals are
specified in "Inspection" and "Maintenance
Intervals".
After it has been washed using a highpressure hose or steam cleaned, the machine
should always be lubricated using a grease
gun. Ensure that the universal joints and
splined shafts are lubricated regularly.
5.14 Handling of
Lubricants
Always exercise extreme care and observe
the recommended hygiene rules when
handling mineral oil products. Details of these
handling regulations can be found in
information provided by the health authorities.
Storage and Handling
• Always store lubricants where they cannot be
accessed by children.
• Never store lubricants in open or unlabelled
containers.
Fresh Oil
• Apart from taking the usual care and observing hygiene rules, there is no need to take
any special precautions when handling fresh
oil.
Waste Oil
• Waste oil can contain harmful contaminants
which may cause skin cancer, allergies and
other illnesses.
Please ensure that you read the following
instructions as well as the relevant
information. This also applies to any of your
employees who handle lubricants.
Hygiene
Lubricants do not present a health hazard
provided they are used for their specified
purpose.
In the case of prolonged skin contact,
lubricants - especially low-viscosity oils - may
remove the natural layer of fat contained in
the skin, resulting in dryness and possible
irritation .
It is important to take extreme care when
handling waste oil as it may contain other
irritants.
Vapours given off by cleaning agents and oils
are also a potential health hazard.
You should therefore not carry any oily cloths
around. Change soiled work clothing as soon
as possible.
Attention!
Oil is a toxic substance. Should you swallow
any oil, do not try to vomit. Contact a doctor
immediately.
Protect your hands with barrier cream or wear
gloves to avoid contact with the skin. Wash
off any traces of oil thoroughly with soap and
hot water.
• Wash your skin thoroughly with soap and water.
• Use special cleaning agents to clean any
dirt off your hands.
• Never wash oil residue from your skin with
petrol, diesel fuel or paraffin.
• Avoid skin contact with any oily clothing.
• Do not keep any oily rags in your pockets.
• Wash soiled clothing before wearing it
again.
• Ensure that any oily footwear is disposed of in
the proper manner.

Measures in case of injury
through oil
Eyes:
Should any oil be splashed into your eyes,
rinse with water for 15 minutes. If the eye is
still irritated, contact a doctor immediately
If oil is swallowed
If oil is swallowed, it is important not to induce
vomiting. Contact a doctor immediately.
Skin irritation caused by oil
In case of prolonged skin contact, wash off
the oil with soap and water.
Oil Spills
Use either sand or a suitable granular
absorbent to soak up any spilt oil. Dispose of
the oil-contaminated absorbent in the proper
manner.
Oil Fires
Never use water to extinguish an oil fire. The
oil will float on the water causing the fire to
spread.
Burning oil/lubricant must be extinguished
using a carbon dioxide powder or foam
extinguisher. Always wear respiratory
equipment when dealing with fires of this type.
Waste Oil Disposal
Oil-contaminated waste and used oil must be
disposed of in accordance with current
legislation.
Waste oil must be collected and disposed of
in accordance with local regulations. Never
pour used oil into unsealed sewage systems
or drains or onto the ground.
5.15 Lubricants &
Hydraulic Oil
Hydraulic System
The hydraulic fluid from the tractor is mixed
with the hydraulic fluid from the machine.
The supplied machine hydraulic system
contains Total AZOLLA ZS 32 oil.
Lubricants
Simba strongly recommend the use of
Lithium Complex EP2 Grease in the disc
and wheel hubs of your SL. This grease is
a Lithium Complex soap dispersed in a mineral oil and is interpreted by IARC as being
non-carcinogenic. Grease cartridges are
available from Simba (P12710). Using this
grease in combination with the labyrinth type
seal it is permissible to lengthen the greasing interval on the disc hubs to 200 hours.
If using a standard agricultural grease the
disc hubs should be lubricated every 50
hours.
Advantages of Lithium Complex EP2
Grease
Excellent mechanical stability.
Excellent load carrying properties.
Wide temperature range.
Excellent oxidation stability.
Excellent water resistance.
Compatability with other greases.
All other lubricating points on the machine can
be lubricated with multigrade lubricating
grease as specified in DIN 51825 KP/2K -
