Dear customer!
We would like to thank you for the confidence in buying this implement.
The advantages of this implement will be shown, only, when operated and
used with due care and attention.
When handing over this implement your dealer has already instructed you
with regard to operation, adjustment and maintenance. But this short intro-
duction requires an additional detailed study of the instruction book.
Therefore read this instruction book carefully before the first use. Please pay
attention to the safety instructions mentioned in this instruction book.
Any changes and modifications carried out not being mentioned expressly in
this instruction book, may only be carried out with a written agreement of the
manufacturer.
Ordering spare-parts
When ordering spare-parts please state type and serial No. of the implement.
This information will be found on the identification plate.
Put down this data on the following table so that it is always available.
Only use genuine Lemken spare-parts. Spurious parts negatively influence
the function of the implement, show a shorter lifetime and increase in nearly
all cases additional maintenance.
We trust that you will understand that LEMKEN is unable to guarantee poor
operation and damage caused by using spurious parts!

1 SAFETY INSTRUCTIONS
General Safety Instructions
• Before using the machine, always check both it and the trac-
tor for roadworthiness and operational safety!
• As well as the notes in these instructions the operator is ad-
vised to comply with the generally applicable safety at work
regulations and those relating to use of the public highway!
• The implement may only be operated, maintained and repaired by such
persons who have been made acquainted with it and who have been ad-
vised about the dangers!
• When driving on public roads with a raised machine the lifting control lever
should be locked against unintentional lowering!
• The fitted warning and advisory plates give important information for safe
operation; adhering to these increases your own security!
• When using public roads adhere to applicable traffic rules!
• The operator should familiarise him-/herself with all controls and their
functions before starting work. During work could be too late!
• The clothing of the operator should fit tight. Avoid wearing any loose clot-
hing!
• To avoid danger of fire keep the implement clean!
• Before beginning to drive check surroundings area (children)!
• Sitting or standing on the implement during operation or during transport
is not permissible.
• Attach implements as advised and only to the stipulated positions!
• Special care should be taken when the implement is coupled to or uncou-
pled from the tractor.
• When coupling or uncoupling the implement bring the supporting stands
into the corresponding position (standing safety)!
• Fit weights only to the fixing points provided for that purposes!

8
• Adhere to the maximum permissible axle loads, total weights and transport
width!
• Fit and check transport gear, road lights and warning guards!
• The release ropes for quick coupler latches should hang freely and in the
lowered position must not release the quick coupling by themselves.
• Never leave the driver's seat whilst in motion!
• Handling behaviour, steerability and braking are influenced by mounted
implements, trailers and ballast weights. Check for sufficient steerability
and braking!
• When driving round bends note the width of the machine and/or changing
centre of gravity of the implement.
• Put implement into operation only when all guards are fixed in position!
• Never stay or allow anyone to stay within the operating area!
• Never stay in the turning and slew area of the implement!
• Do not operate any hydraulic controls while anybody is in the operating
area!
• On all pivoting parts actuated by power assistance (e.g. hydraulics) exists
danger of injury by bruising and crushing!
• Before leaving the tractor lower the machine to the ground. Apply the par-
king brake, stop the engine and remove the ignition key!
• Do not allow anybody between the tractor and implement if the parking
brakes are not applied!
Attached implements
• Before mounting or dismounting implements on/from the three-point linka-
ge, move the raise / lower control to the position at which accidental raising
or lowering cannot take place!
• In the case of three-point linkage mounting, ensure that the tractor balls
and the mounting pins of the implement are of the same category!
• There is the risk of injury from pinch and shear points in the three-point lin-

9
kage area!
• When operating the external lift controls for the three-point linkage, do not
stand between the tractor and implement!
• Always ensure sufficient lateral limitation for the three-point linkage of the
tractor in the transport position of the implement!
• When driving on roads with the implement raised, the raise/lower control
must be locked to prevent lowering!
Hydraulic equipment
• The hydraulic pipes are under pressure!
• When connecting hydraulic rams, the pipes must be connected as direc-
ted!
• Always release hydraulic pressure from both tractor and implement before
coupling!
• When connecting hydraulic pipes to the tractor ensure that incorrect use is
avoided. If the connections are reversed, the opposite function is carried
out (e.g. raising/lowering) and there is a risk of accidents!
• Regularly check the hydraulic pipes and replace them in the event of da-
mage or signs of ageing. The replacement pipes must comply with the
technical specification as laid down by Lemken!
• When searching for leaks appropriate equipment should be used because
of the danger of injury!
• Hydraulic oil escaping at high pressure can penetrate the skin and cause
serious injury! When injured see a doctor immediately! Danger of infection!
• Before working on any hydraulic equipment - lower all implements/attach-
ments, release hydraulic pressure where possible and switch off the trac-
tor engine!
Tyres
• When working on the tyres make sure that the implement has been placed
on the ground safely and that it is secured by chocks against unintentional

10
rolling!
• Fitting tyres requires knowledge and special tools!
• Repairwork on tyres may only be conducted by trained staff and with sui-
table tools!
• Check air pressure regularly and adhere to the advised air pressure!
Maintenance
• Repair-, maintenance- and cleaning operations as well as adjustments
and remedy of function faults should principally be conducted with engine
stopped and brakes applied. Remove ignition key!
• Check and tighten nuts and bolts regularly!
• When conducting maintenance work on a lifted implement always place
suitable supports underneath!
• For replacing any tools with cutting edges always use suitable tools and
gloves!
• Dispose of old oils, grease and filters as prescribed by law.
• Before working on the electric gear disconnect battery cables!
• When conducting electrical welding operations on the tractor or on the
mounted implement remove cable from the generator and the battery!
• Any spare parts fitted must meet with the implement manufacturer's fixed
technical standards! This is for example ensured by using genuine spare
parts!

3 COMPACT INSTRUCTIONS
The following instructions must be done to use the implement effective and
optimal.
3.1 Lower links and top link
The lower links must be arranged
so that they nearly intersect in the
middle between the front and rear
axle of the tractor.
The drawbar (A0) must be fitted in
the top position to ensure a good
entry.
In working position the top link must
be fitted so that it raises towards
the implement.
Incorrect Correct
3.2 Working depth of the tines
The working depth will be adjusted by means of the pins (S1) and (S2) of the
pin adjuster (V1). Range of working depth = 5 cm to 30 cm.
3.3 Reconsolidation effect
The reconsolidation effect of the rollers (W0) will be adjusted via the position
of the top link. The top link should be positioned slightly raised towards the

15
implement.
3.4 Hydraulics
The tractor hydraulics must be set to floating position or mixed control.
3.5 Hollow discs
The hollow discs (K3) must be adjusted in depth by means of the pin adjuster
(V4), so that they level the dams, which were made by the tines (H0) of the
rear row.
3.6 Outer discs
The working depth of the outer discs (R0) must be adjusted a little shallower
than the hollow discs (K3), and that by means of the pin adjuster (V4).

4 PREPARATION OF THE TRACTOR
4.1 Tyres
Ensure that all tyres - especially the rear ones - are at identical pressure.
(See manufacturer's instructions)!
4.2 Lift rods
Adjust lift rods to equal length. Where there are alternative positions for the
lift rods on the lower links, use the rearmost position, to unload the tractor hy-
draulics.
4.3 Check chains or sway blocks
It is essential that the check chains or sway blocks are adjusted so that the
lower links are free to move sideways when in working position.
4.4 Tractor hydraulics
During work the tractor hydraulics must be set to „floating position“ or „mixed
control“.
4.5 Required power sources and sockets
For the electric use of the implement the following power sources must be
available with the tractor.
Function Voltage Direct connection
to the battery
Socket
Lighting equipment 12 - according to
DIN-ISO 1724

17
4.6 Required spool valves
For the hydraulic use of the implement the following spool valves must be
available at the tractor:
4.7 Axle load
The attachment of implements to the front- and rear-three point
linkage must not lead to exceeding the allowed total weight, the
allowed axle load and the allowed tyre load of the tractor.
The tractor front axle must always be loaded with 20 % of the
tractor dead weight at minimum.
How to calculate the minimum front ballast and the increasing of the rear axle
load, is described in detail as follows:
GV= Weigth of front ballast (front implement)
TV= Front axle load of the tractor without mounted implement
TL= Tractor dead weight
TH= Rear axle load of the tractor without mounted implement
GH= Weight of the implement combination

4.7.1 Calculation of the minimum front ballast GV min:
4.7.2 Calculation of the increasing of the rear axle load:
Minimum axle load increasing
The calculation of the required minimum front ballast and the increasing of the
rear axle load requires that all above mentioned measurements and weights
are known. If they are unknown and cannot be found out, there will be only
one way to avoid overloads:
Please weigh your tractor with mounted and lifted implement to find out
the actual rear axle loading and front axle unloading and that in compa-
rison with the axle loads of the tractor without implement!
