1.2 Use for the Intended
Purpose
The Simba Great Plains Single 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 Simba Great Plains Single 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.
Use of the Single Press behind high power
tractors (in excess of 40% above the
maximum recommended) can lead to high
loads and stresses which can cause long
term structural damage to the chassis and
key components. Such overloading can
compromise safety and is to be avoided.
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 Single 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).
Therefore, it is crucial to always
check your machine before and
durin g operat ion for c orrect
operation and adequate application
accuracy.

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 th e
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.

Operating Instructions, and
• ensure that the operator has read and
understood the instructions.
• make sure that the operator is aware of the
specic regulations relating to the machine
when driving on public roads.
1.7 Servicing &
Maintenance
Ensure that regular checks and inspections
are always carried out within the periods
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
13Single 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
safe condition. Hoses which exceed 6 years
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

12. Fit the Single Press wing transport
strap to tie the two wing sections
together.
13. Ensure that parking stands are locked
up in their work position.
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 Single Press is applied to the
drawbar of the disc cultivator.
The frame may be levelled by altering the
rearward tilt of the Single Press to increase
or reduce the loading on the disc rear
drawbar.
5. Raise the Single Press drawbar above
the disc cultivator drawbar (200mm
approx.). Depth control shims may
need to be removed.
6. Raise the disc cultivator to the same
height as the Single Press drawbar
then reverse the disc cultivator to
couple the two machines together.
7. Fit the drawbar pin.

2.6.2 Transporting a Single
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 Single 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.
2. Transportation / Installation
Extreme caution must be taken when
the Single 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.
MAXIMUM ROAD TRANSPORT SPEED 16
MPH (25 km/h).
2.6.3 Changing from Wor k
to Road Tr ansport (Single
Press Towed Behind a Disc
Cultivator)
1. Operate the hydraulics to raise the disc
and Single Press.
2.7 When Driving on the Road
When driving on the road the machine must
be converted to the transportation position.
When driving on the road, raise
the machine completely to prevent
any elements dragging on the
ground.
2.8 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!).
2. Operate the hydraulics to fold the
wings on both the disc cultivator and
the Single Press.
3. Fit the transp ort st raps to both
machines.
It may be necessary to shorten
the drawbar cylinder of the disc
culti vator until the c hassis is
horizontal or slightly nose down
before moving the machines.
Shortening the Single 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.
• Park the machine on level and solid ground.
• With the machine raised move the
parking stands into position.
• Lower the machine onto the parking
stands ensuring that it is stable.
• Place the wheel chocks into position.
• 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 lines from the
tractor.
If parking on uneven or sloping
ground unfold the machine and
lower rst to avoid instability.

The Simba Great Plains Single Press is a
versatile implement designed to perform
effective consolidation. The Single Press
may be towed on its own or in tandem behind
another implement e.g. disc cultivator.
1
2
The use of the Single Press in tandem with
a disc cultivator for straw incorporation
consolidates the straw/soil mix through the
soil prole. This ensures 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.

4.2 Double Disc Roller
The standard DD700 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.
4. Adjustment / Operation
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.
Fig. 4.02: Double Disc Roller
Fig. 4.03: Aqueel 2 Roller
4.4 Levelling Boards
The action of the sprung leaf type levelling
boards is to carry and drop soil to level in
front of the press rings, to rub clod against
clod for additional soil breakdown, to force
clods down into the soil prole and to present
remaining clods passing between the leaves
into the row of press rings.
The levelling boards are set using shims in
the levelling board cylinders. During work,
these cylinders should be retracted onto the
shims but can be extended to release any
soil / trash build up.
4.3 Aqueel 2 Roller
The Aqueel 2 is a rubber, specialist selfcleaning tyre which leaves a patterned
sur fac e profile consisti ng of con ica l
indentations. This is designed to combat
surface water movement and wind erosion
in the eld. The benet of Aqueeled ground
(reservoir tillage) is gained on light, easy
working soils that can slump or compact.
23Single Press
Operating Instructions
4. Adjustment / Operation
4.5 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 the
accumulators in the hydraulic system.
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 Single 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 rings
which could lead to reduced drive and hence
blockage of the axles.
Running the Single 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.
If the roll axles start to block regularly this
may also be an indication that the ground
conditions are too wet for the Single Press
to be effective.
It is not necessary to tilt the Single Press onto
the transport wheels during headland turns
whether the machine is used independently
or in tandem with a disc cultivator. Normally,
the Single Press should be tilted onto the
roll to a point where the rear axle wheels
are clear of ground contact.
Shims should be added to the levelling board
cylinders until the levelling boards are carrying soil. The levelling boards will need to
be set higher during 1st pass operations
especially on ploughed land where large
clods may not be able to pass under or between the sprung leaves. The boards need
to carry a certain amount of soil to effect a
levelling operation and also to give a clod
to clod crushing action.
4.6 Pitch Control
Pitch control on the Single 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.
In practice it is possible to use the Single
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 Single Press. Often the use of
the press 12 - 24 hours after a disc cultivator
(or longer following a plough) gives a far
superior surface consolidation effect.
It is not necessary to tilt the Single 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.

4.7 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.
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.
4.8 Work Instructions
Driving speed
The Single 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.
When reversing the UniPress into
corners when working headlands
ensure that the levelling boards
are fully raised and the machine
tilted onto the roll rings far enough
to allow the lower ends of the
sprung leaves to clear the ground.
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 (children!) is
in the manoeuvring area.

4.9 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)
Working Elements
• Are the double disc rings and other
cul tiva tion to ols in a service able
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.
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.

5.5 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 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
mus t no t be oil ed. Remo ve
any traces of oil with a suitable
cleaning agent.
5.6 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
• Serial Number of Machine
• Date of Purchase and Operating Hours
• Type of Problem
5.7 Maintenance Intervals
Apart from daily m a i ntenanc e , t h e
maintenance intervals are based on the
number of operating hours and time data.
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 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
s u p p o r t s w h e n w o r k i n g

5.8 To Adjust the System Pressure
A low oil ow should be used,
i.e., tractor tickover or low ow
selected.
The wing circuit is controlled by an
overcentre valve 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
dealer, and detailed maintenance
instructions.
If the system needs adjusting, fully raise the
machine, partially fold the wings & hold them
in this position. To adjust the pressure utilise
valve A (shown in Fig. 5.01). Unscrew the
adjusting screw:
• Turning adjuster clockwise increases
pressure at wing tips.
• Turn ing adju ster anti-clo ckwi se
decreases pressure at wing tips.
Once the desired setting is achieved lock
the valve.
FRONT OF MACHINE
A
In some cases it may be necessary to
adjust the wing fold circuit pressure. Higher
pressure will cause the wing tips to dig in
causing the centre of the machine to lift it
out. Too little pressure will cause the wing
tips to lift out & the centre of the machine
to dig in. When towing another implement
behind the Single Press, the pressure may
need increasing to compensate.
In all cases, regardless of tractor make,
adjustment should start from minimum
pressure and gradually increase up to
desired pressure.
Valve adjustment should be
carried out in small increments. A
full turn of the valve will cause a
signicant change in the operation
of the machine.
Fig. 5.01: Adjusting system pressure
Only valve A should be adjusted. All
other valves are set at the factory
and should not be tampered with.
