Operating Instructions
1. Safety Data
1.2 Use for the Intended
Purpose
The Simba Great Plains Double Press
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.
Origin al parts and accessories from
Simba Great Plains 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 Great Plains
products may have a detrimental effect on
specic design features of the machine and
affect the safety of machine operators and
the machine itself. Simba Great Plains will
accept no liability for damage resulting from
the use of non-original parts or accessories.
The Double Press 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 Great
Plains will accept no liability for damage
resulting from improper use. The risk will be
borne solely by the operator.
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 Great Plains.
The “Machine Registration” form is to be
completed and returned to your dealer.
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 tig htn ess and re tig hte n if
necessary.
In the event of malfunctio ns,
stop and secure the machine
immediately.
Ensure that any faults are remedied
immediately.
1.4 No Liability for
Consequential Damage
The Double Press has been manufactured
with great care. However, problems may
still occur when it is used for the intended
purpose. These may include:
• Worn wearing parts.
• Damage caused by external factors.
• Incorrect driving speeds.
• Incorrect setting of the unit (incorrect
attachment, non-adherence to the Setting
instructions).
Use of the Double Press behind high
power tractors (in excess of 40% above the
maximum recommended) can lead to high
loads and stresses which can cause long

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 gures are shown on the
serial plate).
Passengers on the machine are
strictly forbidden!
Max. road transport speed 16mph
(25km/h).
1.6 Accident Prevention
In addition to the Operating Instructions, it is
important to observe the accident prevention
regulations specied by agricultural trade
associations. It is the Operator’s responsibility
to ensure that all other persons are excluded
from the danger zones surrounding or on the
machine during its operation.
It is the Owner’s responsibility to ensure:
• the Operator is trained and competent to
use the machine & tractor,
• the tractor is suitable for the machine
• adequate Risk and COSHH assessments
have been undertaken regarding the
machine’s use. Specically, these include
issues concerning contact with the soil,
dust, crop residues, chemicals, lubricants
and other compounds during operation or
maintenance, and the possibility of stones
being ejected at high speed during work.
Beware of trapping hazards when
manipulating the parking stands
or other moving parts. Ensure
any heavy components are fully
supported when removing pins /
bolts.
1.6.1 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 rm, level ground.
1.6.2 On the Hydraulic System
Do not connect the hydraulic lines to the
tractor until both hydraulic systems (machine
and tractor) are depressurised.
Any hydraulic system containing
an accumulator can re main
under pressure permanently
(even after following manual
depressurisation procedur es
with a t ractor / 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 ttings 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.

required by law or specified in these
Operating Instructions.
When carrying out service and maintenance
work always:
• switch off the tractor engine and remove
the ignition key.
• wait until all the machine parts have
stopped moving.
• depressurise the hydraulic system.
Many hydraulic circuits contain lock or
overcentre valves which can retain pressure
in the lines even after depressurising the
tractor side of these circuits. If in doubt,
consult trained personnel (such as your
local Simba Great Plains dealer) to ensure
such valves are depressurised to the correct
procedure before removing or servicing
any parts connected downstream of these
valves.
Operating Instructions
13Double Press
1. Safety Data
Check all hydraulic lines for leaks, loose
connections, chafe marks and damage.
Remedy any deciencies immediately! Pay
particular attention to hose renewal intervals
as outlined in the specic sections which
follow. ALL hydraulic hoses have a safe
maximum working life of 6 (SIX) years from
date of installation, provided they remain in a

of age should be replaced, or inspected and
certied by a suitably qualied person to
have an extended life period which should
be recorded.
Pay particular attention to those items which
require specialist service tools or training
to be carried out by qualied personnel. Do
not attempt to service these items yourself!
These include items retaining pressure (e.g.
accumulator circuits), or force (e.g. spring
tines), and DD Rolls of any type.
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.
1.8 Operating Areas
The operating areas include the drawbar,
hydraulic connections and depth adjustment
equipment as well as all operating points
requiring maintenance.

2. Transportation / Installation
2.4 Hitching Up
When hitching-up the machine,
ensure that no-one is between the
tractor and the machine.
When the Double Press 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 Double Press in the
folded position (using the parking
stands provided) 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 ow and consequent
power usage and heat generation.
2.4.1 Hitching up a Tractor to
the Double Press / Preparing
for Transport
1. Couple the four hydraulic hoses to
the tractor ensuring that the two wing
hoses are together and the two drawbar
cylinder hoses are together.
2. Use the hydraulics to raise or lower the
height of the shackle before hitching up
to the tractor drawbar clevis.
Do not use the tractor pick-up hitch
to attach the machine to the tractor.
This could cause damage to the
tractor and the machine.
3. Carefully operate the hydraulics to
lower the drawbar and tilt the Double
Press onto the road transport wheels.
Fully extend the drawbar cylinder.
4. Operate the hydraulics to fold the
wings.
Do not open taps while tractor
hydraulics are in oat.
The hoses in the lift circuit have
a maximum rated pressure of
415bar, and should be replaced

connect the machine to the tractor as
instructed to in Section 2.4.1.
2. With the machine connected couple
the air lines. When coupling ensure the
yellow line is attached rst followed by
the red line.
4. Continue de-coupling the machine until
it is fully disconnected.
By following the above instructions
you will see that at NO point
in the coupling or decoupling
process has the red line been
left in the tractor on its own.
This is intentional and should be
considered the ‘rule’ to coupling
the hoses.
3. Your brake hoses are now attached
and are ready for operation.
4. Continue with the coupling process as
instructed in Section 2.4.1.
2.6.2 When De-coupling
1. Bring the machine to the parking
position as instructed to in Section 2.9.
2. With the machine still connected to
the tractor remove the red brake line
followed by the yellow line.
3. Your brakes will now be ON and will
hold, ensuring they have been adjusted
and maintained correctly, the machine
in position. (note: if the machine‘s tank
is drained of air once all lines have
been detached the brakes will come off
(same situation as pushing the shunt
valve).

2.7 Preceding & Trailing
Implements
Adding a preceding or trailing
implement to the Double Press will
affect the stability and handling of
the machine both in transport and
work.
2.7.1 Hitching a Disc Cultivator
Ahead of the Double Press
1. Remove the transport straps from the
disc cultivator, exercise great CARE
when extending the axle cylinder.
2. Reverse the disc cultivator up to the
Double Press drawbar ensuring that
the two drawbars are aligned allowing
a slight clearance to e nable the
machines to be coupled together.
8. Operate the hydraulics to lower the rear
axle and drawbar, tilting the Double
Press onto the road transport wheels.
Fully extend the drawbar cylinders.
9. Fully raise the levelling boards.
10. Operate the hydraulics to fold the
wings.
11. Operate the hydraulics to lift the disc
cultivator into the transport position.
12. Fit the disc cultivator transport straps.
13. Fit the Double Press wing transport
strap to tie the two wing sections
together.
14. Ensure that parking stands are locked
up in their work position.
3. Lower the disc cultivator to the ground.
4. Connect the hydraulic hoses from the
Double Press into the disc cultivator
rear outlets ensuring that the wing
hoses are together and the drawbar
cylinder hoses are together. Ensure
that the folding circuits and lift drawbar
circuits are coupled correctly.
5. Raise the Double Press drawbar above
the disc drawbar (200mm approx.).
Depth control shims may need to be
removed.
6. Raise the disc cultivator to the same
height as the Double Press drawbar
then reverse the disc cultivator to
couple the two machines together.
With both machines in the transport position
i.e. raised and folded, the chassis of the disc
cultivator should be slightly nose down or
horizontal even when the downward load
from the Double Press is applied to the
drawbar of the disc cultivator.
The frame may be levelled by altering the
rearward tilt of the Double Press to increase
or reduce the loading on the disc rear
drawbar.
7. Fit the drawbar pin.

2.7.2 Transpor ting a Press
Towed Behind a Disc Cultivator
With both machines in the transport position
i.e. raised and folded, the chassis of the disc
cultivator should be slightly nose down or
horizontal even when the downward load
from the Double Press is applied to the
drawbar of the disc cultivator. The chassis
should NEVER be tail low in transport as
this will give a high negative loading on the
tractor which could lead to loss of traction
to the rear wheels.
Extreme caution must be taken when the
Double Press is transported up steep
gradients and across side slopes. Higher
drawbar loading can be achieved by
shortening the drawbar cylinder.
Prior to leaving the eld to travel on a public
highway ensure that any clods of soil are
removed from the machine to prevent them
from fouling the road.
Shortening the Double Press drawbar
cylinder will increase the loading on the rear
of the disc cultivator frame. If necessary this
can be used to level the chassis for road
transport.
2.7.4 Rear Drawbar Setting
To prepare the rear drawbar for use:
1. Open the tap on the rear drawbar
cylinder.
2. Retract the cylinder and insert pin.
3. Close the tap to secure its position.

The Simba Great Plains Double Press is a
versatile implement designed to perform an
excellent shallow cultivation combined with
effective consolidation. The Double Press
may be towed on its own or in tandem behind
another implement e.g. disc cultivator.
1
2
The Double Press consists of a row of
leading tines followed by two rows of
intermeshed press rings.
The use of the Double Press in tandem with
a disc cultivator for straw incorporation, is to
consolidate the straw soil mix through the
soil prole ensuring maximum straw soil
contact to increase the breakdown process,
minimise slug problems and to leave a rm
weatherproof nish.
It can be used in reduced tillage systems
behind a disc cultivator to incorporate stubble
or to work down ploughing on medium to
heavy soil types. Like all Simba Great Plains
machines it features the latest innovations
which combine to give an efcient, well-built
unit with unrivalled reliability.

4. Adjustment / Operation
4.2 Leading Tines
The leading tines are individually adjusted,
utilising eighteen different height settings and
three different rake settings. Added security
of shear bolt protection ensures trouble free
operation in tough, arduous conditions.
The ability to effectively eradicate tractor
wheelings without moving dry clods onto
the wheelings is most important for even
germination.
4.3 Double Disc 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.
The DD roller carries a proportion of the
machine’s weight to ensure consolidation.
The corrugated surface left by the roller is
weatherproof both for wet or dry situations.

4. Adjustment / Operation
4.4 Work Settings
In work the wing cylinders should be fully
extended. The gangs are able to oat over
any undulations on the ground due to their
oating frames.
Optimum performance has been found
to be achieved when the press roll rings
have worn away the painted nish leaving
a smooth shiny surface. When the press
roll 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 Double Press should be run with the
chassis level front to rear by extending the
drawbar cylinder to the necessary position.
The cylinder should not be over extended
as this will remove the load on the front row
of rings which could lead to reduced drive
and hence blockage of the axles.
It is not necessary to tilt the Double Press onto
the transport wheels during headland turns
whether the machine is used independently
or in tandem with a disc cultivator. Normally,
the Double Press should be tilted sufciently
onto the rear roll for the tines to clear the
ground (at which point the rear axle wheels
will still be clear of ground contact).

Operating Instructions
4. Adjustment / Operation
4.5 Pitch Control
Pitch control on the Double Press is
governed by the quantity of shims tted to
the drawbar cylinder. Increasing the number
of shims will lift the front of the chassis when
lowered into the work position.
Running the Double Press level allows the
press rings to give an even consolidation
and clod crushing action.
Running the machine significantly nose
down or raised will reduce the load on the
rear axle leading to loss of drive of the axle
and then blockage, together with a reduced
consolidation effect.
If any roll axle starts to block regularly, this
is generally an indication that the roll axle
is not tight. Failure to keep the axles tight
results in loss of drive between each pair of
rings allowing rings to turn individually on
the axle. Should this occur the axle must
be tightened immediately to prevent any
damage occurring to the axle shaft.
It is not necessary to tilt the Double Press
onto the transport wheels during headland
turns whether the machine is used independently or in tandem with a disc cultivator.
Full y ext endi ng th e dra wbar
cylinder and then reversing into
the headland furrow could lead to
damage of the cylinder.
If the roll axles start to block regularly this
may also be an indication that the ground
conditions are too wet for the Double Press
to be effective.
In practice it is possible to use the Double
Press on ground conditions that are unsuitable to achieve the desired effect, and it
is usually possible to operate the machine
without regular blockage under such unsuitable conditions, assuming that the axles are
tight and rings smooth.
As such, especially under wet conditions, it
is advisable to check on the cultivation effect
of the Double Press. Often the use of the
press 12 - 24 hours after the disc or longer
following the plough gives a far superior
surface consolidation effect.

4.6 Using Shims
Before using shims to alter machine settings
ensure the machine is stationary and the
tractor is turned off with the keys out. Ensure
that all operators are clear of the machine
and that no load is being held on any existing
shims in the cylinder.
To t the shims hold them by the handle and,
using a rm action, clip them onto the rod
as shown in Fig. 4.04. They are removed by
using a nger to pull rmly on the handle.
Check the cylinders for damage
and debris before tting shims.
Only attempt to add or remove
shims using the handle. Trying to
manipulate shims using the jaws
could result in injury.
4.7 Work Instructions
Driving speed
The Double Press 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.
Beware of stones being thrown by
the spring action of tines returning
from their stressed state in work.
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 changing machine settings
ensure both sides of the machine
mirror each other. The left hand
cylinder should contain the same
amount of shims as the right, for
example. Failure to do this could
result in damage to the machine.
When manoeuvring the machine,
pay attention to your surroundings.
Ensure that nobody (children!) is
in the manoeuvring area.
• Park the machine on level and solid ground.
• With the machine raised, lower the
parking stands into position.
• Lower the machine onto the parking
stands ensuring that it is stable.
• Remove the drawbar pin and drive forward
slowly until hitch is clear of tractor drawbar.
Lower the drawbar to the ground.
• Switch off the tractor.
• Disconnect hydraulic and electric lines
from the tractor.

4.8 Checks
The working qu ality de pends 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 and electric lines
been connected according to the colour
coding?
• Is the machine in a level operating
position and the working depth set
correctly?
• Regularly inspect the machine for
damage and signs of overloading (stress
cracks on welded joints, frame distortion)

5. Servicing and
Maintenance
Follow the safety instructions for
servicing and maintenance.
Maintenance work should only
be undertaken with the machine
unfolded and lowered or on stands
with the hydraulic taps shut.
When working under the machine
ensure that the tractor handbrake
is on.
5.1 Servicing
Your machine has been designed and
constructed for maximum performance,
oper ation al efficie ncy an d ope rator
friendliness under a wide variety of operating
conditions.
5.3 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.
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.
Avoid cleaning the roll bearings with a
high-pressure hose or a direct water jet.
The housing, screwed connections and ball
bearings are not watertight.
5.4 Hydraulics
A low oil ow should be used,
i.e., tractor tickover or low ow
selected.
The wing circuit is controlled by an
overcentre valve contained within
the manifold block which positively
locks oil ow 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 ttings
without prior reference to your
authorised Simba Great Plains
dealer, and detailed maintenance
instructions.
