1 SAFETY INSTRUCTIONS
•Before use, always check both the machine and the tractor for road-
worthiness and operational safety.
•As well as the notes in these instructions the operator is advised to
comply with the generally applicable safety at work regulations and
those relating to use on the public highway.
•Do not wear loose clothing.
•Before starting work, familiarise yourself with all equipment and working parts as well
as their functions. It is too late for this when you are working.
•Keep the machine clean.
•Couple the implement as instructed using the stipulated fixings, only!
•Special care is required when coupling and uncoupling implements to or from the
tractor.
•Release cables for quick-action three point linkage couplings must hang loosely and
must not release themselves at the lowest point.
•Before starting the engine and engaging the PTO check the area around the machine
(e.g. children).
•Riding on the implement both during work and during transport is not allowed.
•Never leave the driver's seat whilst the tractor is in motion.
•Driving conditions, steering and braking are affected by mounted or towed imple-
ments and ballast weighs. Therefore, ensure sufficient front end weight for steering
and braking!
•When cornering, take into account the wide overhang and/or the centrifugal effect of
the implement.
•Only engage the implement if all the protective fixtures are attached and are in the
working position!
•Do not stand in the working area!
•Do not stand in the turning and swinging area of the implement.
•Hydraulic devices must only be operated if nobody is standing in the swinging area!
•Before leaving the tractor, lower the implement onto the ground, switch off the engine
and remove the ignition key!
•Nobody must stand between the tractor and implement unless the tractor is secured
to prevent it rolling away by the parking brake and/or by wheel chocks.
•Lock the wheel track eradicators in the transport position!
Mounted implements
•Before coupling and uncoupling implements on/from the three-point linkage, move
the raise / lower control to the position at which unintentional raising or lowering can-
not take place!
•In the case of three-point linkage, ensure that the tractor linkage balls and implement
pins are of the same category.
•There is risk of injury from pinch and shear points in the three-point linkage area!
•When operating the external lift controls for the three-point linkage, do not stand be-
tween the tractor and implement.
•Always ensure sufficient lateral limitation, for the three-point linkage of the tractor, in
the implement transport position.
•When driving on roads with the implement raised, the raise/lower control must be
locked to prevent lowering.
Hydraulic equipment
4

•The hydraulic pipes are under pressure.
•When connecting hydraulic services, the pipes must be connected as directed.
•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. rais-
ing/lowering) and there is a risk of accidents!
•Regularly check the hydraulic pipes and replace them in the event of damage or
signs of ageing. The replacement pipes must comply with the technical specification
as laid down by Lemken.
•Hydraulic oil escaping at high pressure can penetrate the skin and cause serious
injury!
•Before working on any hydraulic equipment - lower all implements/attachments, re-
lease hydraulic pressure where possible and switch off the tractor engine.
Maintenance
•Whenever possible, only carry out work on the implement when it is lowered onto the
ground with the PTO drive disengaged, and the tractor engine at rest with the ignition
key removed.
•Always ensure safety when working on a raised machine by the use of suitable, se-
cure supports.
•Regularly check all nuts and bolts, and tighten these if necessary.
•Dispose of oil and grease properly.
•In the event of welding being required on the implement ensure that, if a tractor is
attached, its battery/alternator is disconnected.
•Only use genuine or approved replacement parts when repairing the implement. The
warranty could be declared null and void if this is not done.

3 PREPARATION OF THE TRACTOR
3.1 Tyres
Ensure that rear tyre pressures are equal and correct! (Refer to the tractor handbook).
3.2 Lift rods
Adjust the lift rods of the three point linkage to an equal length by means of the adjust-
ment provided!
3.3 Three-point linkage
The tractor as well as the soil cultivation implement must be equipped with a Cat. II
three point linkage.
3.4 Check chains / sway blocks
Check chains or sway blocks must be ad-
justed so that the lower links are sufficiently
free to move sideways during work.
3.5 Front Weights
Fit manufacturer’s standard front weight kit or
equivalent. Extra front ballast may be required
following a check on stability with the imple-
ment raised or whilst working with maximum
weight transference. If at least 20 % of the
tractor weight is on the tractor front axle, with
a raised implement, safe steering of the trac-
tor is ensured when driving carefully.
3.6 Hydraulic equipment
The following spool valves must be available at the tractor for the mounted seed drill
EURODRILL:
Required spool valves
single acting double acting
Hydraulic track markers 1 ---
Hydraulic coulter lifting device 1 ---
Hydraulic coulter pressure device 1 ---
Hydraulic track marker with hydraulic "pre-
germination marker"
1 ---
Hydraulic rear linkage (of the Zirkon) 1 or 1
3.7 On-board computer LH 1600
For the on-board computer LH 1600 a socket (SD) according to DIN 9680 must be
available. If the tractor has no suitable socket, it can be ordered as a kit, part No. 573
5012.
It is important that the socket is fitted correctly. If the socket is fitted incorrectly
damage will occur at the circuit board (P) in the junction box. The pole 15/30 must
be fitted to (+) of the battery and the pole 31 to (-) = earth connection.
7

The correct polarity of the socket (SD) can be
checked without danger of damaging the circuit
board as follows:
1. Pull out plug from the junction box cable out
of the on-board computer.
2. Only then fit the power plug of the on-board
computer to the socket (SD) of the tractor.
If the display is still dark, a failure may exist of
the on-board computer. (Provided that the
socket of the tractor isn't defective).
Further information can be found in the instruc-
tion book of the on-board computer LH 1600.
4 ATTACHING AND DETACHING OF THE SEED DRILL
4.1 General Instruction
Before attaching as well as detaching the
tractor hydraulics must be set to position con-
trol. Attach and detach the implement on firm
and level ground, only.
4.2 Attaching
Attach the machine either directly to the three
point linkage of a tractor, a power harrow or a
rotary harrow.
If the seed drill is attached to the three point
linkage of a power harrow or a rotary harrow,
the soil cultivation implement must be at-
tached to the three point linkage of the tractor
before.
As standard the EuroDrill is equipped with the
drawbar Cat. II.
The top link pin can be used alternatively for
category I or II.
Adjust the top link (OL) so that the machine
stands nearly vertically during work.
•Ensure sufficient clearance
between tractor and im-
plement when lifting the
machine (danger of damages)!
•Read and adhere the safety instructions for mounting the imple-
ment!
8

4.3 Parking the implement
The EuroDrill will be supplied with lifted coul-
ters and without fitted harrow for dispatch
reasons. For this reason two outer coulters
are fitted as stands.
With the seed drill of 4,00 m and 4,50 m an
additional stand is fitted.
If an outer coulter as stand and as track
scraper is fitted, it will be adjusted for height
accordingly. The adjuster screw (ES) must
always be retightened after each adjustment.
With the other types of coulters the outer coul-
ter is locked by means of the stay (FL) or (30).
Before first using the drill the flat steel is
swung-upwards and hung at the side plate
(SB) of the implement and secured.
If a harrow is fitted it works as a stand and no additional safety measures are required.
5 USE
5.1 General Instructions
Some parts of the Lemken seed drill will be
delivered loose or not fitted in the working
position for dispatch reasons. These parts are
for example the harrows and the pre-
germination markers. The fitting instructions
are stated in the corresponding sections.
For the seeding procedure
1. the seed drill must be adjusted for the type of seed to be sown and
2. the required seed rate must also be set.

*Gearbox adjustment for the first calibration test 1.
a) Switch off agitator shaft
b) Fit grass seed agitator device
The adjustment information for the setting of the seed drill and the adjustment of the
first calibration test can be taken from the above table.
By means of the Lemken calculation slide the required gear box adjustment can be cal-
culated after the first calibration procedure (picture LRS-01 and LRS-02).
Warning: Do not put parts into the hopper, as the agitator shaft turns when moving the
implement and damages can occur.
10

5.2 Filling the hopper
Before filling the bottom flaps must be ad-
justed!
The hopper may only be filled when the
seed drill is fitted to the tractor or fitted to the
tractor with a soil cultivation implement.
No foreign parts (like a packing list) may be
inside the hopper. They can cause clogging
and damage.
When opening the cover of the hopper, the
ball (SK) of the level indicator (FA) will also
be lifted. Finally this ball lowers again on to
the filled seed.
Therefore it must be ensured that the seed
is distributed equally in the hopper.
When working in hilly conditions, the seed
can move and the level indicator shows the
incorrect value. In this case it is recom-
mendable to fit intermediate plates which are
available as an option.
The filling of the hopper with sacks is
much easier when the sack is not thrown
into the hopper but put on the opened
hopper cover.
Attention: Do not put hand into the hopper
while the agitator shaft is run-
ning!
5.3 Adjustment of the seed drill for each
seed
For a good and even seeding result the fol-
lowing devices must be adjusted:
−Agitator shaft
−Slides
−Bottom flap (adjustment before filling)
−Combi-seed wheel Vario-Plus
−Grass seed agitator (assemble before filling the hopper)
5.3.1 Agitator shaft
With fine seed, especially with coated rape, the agitator shaft (RW) must be switched
off. Therefore the linch pin (KS) is removed from the driving sprocket.
For extreme awney and light grass seed a grass seed agitator (additional equipment)
can be necessary, in order to avoid bridging.
11

The agitator rods are fitted to the agitator shaft by means of clamps. (Picture DKA-34).
5.3.2 Slides
By means of adjusting the slides (AS) in four
steps the seed flow to the seed wheel hous-
ings can be regulated.
0 = Position "CLOSED“ for closing the re-
quired row.
1 = Position "1" for fine seed like rape.
2 = Position "2" for most types of crop and
large-grained seed.
3 = Position "3" for extreme awney and
light seed like awney-wheat.
Warning: Never position a slide into an intermediate position, as the spring effect of the
notch is lost and the seed quantity of the seed drill will be unequal.
5.3.3 Bottom flaps
For careful seeding spring loaded and ad-
justable bottom flaps are provided below the
Combi-Seed Wheels Vario-Plus. By means
of the adjusting lever (EH) 6 different bottom
flap positions can be adjusted:
1. notch for rape 2. notch for wheat
3. notch for awney-wheat 4. notch for lupines
5. notch for peas 6. notch for beans
Notice: With large-grained seed (peas,
beans) either the 5. notch or 6. notch must be chosen according to the size of
the seed. Without the correct bottom flap lever adjustment the seed quantity
may not be carried out. Too wide opened bottom flaps causes uneven seed-
ing. Too small opened flaps can damage the seed.
12

5.3.4 Combi-Seed Wheel Vario-Plus
The Combi-Seed Wheel VARIO-PLUS can be adjusted in three different adjustment
positions. With these seed wheels all usual kinds of seed can be seeded.
Full seed wheel (1/1):
With this adjustment both halves of the seed wheel are switched on. This ad-
justment will be chosen for most types of crops and large-grained seed.
Half seed wheel (1/2):
With this adjustment the right or left half of the seed wheel is switched off. This
adjustment will be used especially for a seed quantity between 30 and 100
kg/ha.
Fine seed wheel (F):
With this adjustment both halves of the seed wheel are switched off. This ad-
justment will be used for fine seed.
5.3.5 Switching on and off of the seed wheel halves
By means of moving the red cam slide (RS)
to the outside, the seed wheel halves are
switched off. They touch at the seed wheel
housing and prevent turning of the seed
wheel halves. For operating the cam slide a
small screwdriver must be used.
For switching on the seed wheel halves, first
the seeding shaft is adjusted by means of
the calibration handle so that the groove is in
view. Now the right seed wheel shaft can be
engaged by mean of moving the red cam
slide to the middle of the seed wheel (notch
lies exactly above the groove of the seeding
shaft). The engaged position of the left seed
wheel half lies 2 pegs behind. Both positions
can also be recognised by the lateral groove
(KE) at the fine seed wheel.
The switchable seed wheels to stop the seed
wheel can be adjusted in the turned position.
In this case, the intermediate shaft is swung backwards against the springs and the
switchable seed wheels turned by hand so that the cam slides can be switched.
13

5.3.6 Adjustment of the seed rate
The seed rate is adjusted by means of the
gear box (GT).
The gear box can be changed stepless by
means of the adjuster lever (SH) after the
knob has been loosened. The higher the
number on the scale the higher is the seed-
ing quantity. A percentage increase of the
gear box adjustment leads to a comparable
percentage increase of the seeding quantity.
If the scale value is doubled for example, the
seed quantity will be doubled, too. By means
of the Lemken calculation slide the required gear box adjustment can be calculated eas-
ily after the first calibration test.
Before starting to seed it must always be checked whether the adjusted seed rate is
sufficient. This is checked by a calibration test.
Warning: Secure handle (SH) so that the gear box does not adjust unintentionally.
5.4 Calibration test
For checking the adjusted seed rate a calibra-
tion test is carried out as follows:
a) Fill the hopper.
b) Swing down the calibration trough (AM).
c) Open the emptying flaps by means of the
emptying lever (EH), and by turning the
hexagon shaft (SK).
d) Adjust gear box to maximum position = 150
e) By means of turning the calibration handle
(KU) of the gear box (GT) fill the calibration
trough twice or three times.
a) Adjust the gear box (GT) according to the
calculation slide for the first calibration test
b) After each filling empty the calibration trough
and fit it again.
c) Go to the gearbox of the seed drill with the
programmed on-board computer LH 1600.
d) With the on-board computer LH 1600 in one
hand turn the calibration lever (KU). The
display of the on-board computer shows the
tramline rhythm. If this rhythm is equal to the
current track (for example 3:3 or 5:5), the
rhythm must be switched forward or back-
wards by means of the arrow keys (3) or (4)
(Drawing BC-01).
BC-01
e) As the implement is parked, a warning signal can be heard. With the delete key (8)
switch off the warning signal and press the key (7). The hectare per field display ap-
pears. The display must be set to zero by means of pressing the delete key (8).
f) According to the following table the required No. of handle turns depends on the
working width of the seed drill. Turn the calibration handle (KU) so that the display
shows 0,01 for 1/100 ha, 0,1 for 1/10 ha or 0,02 for 1/50 ha.

e) Weigh the seed which is caught in the calibration tray and convert it into 1 ha:
Weighed out quantity of seed for 1/50 ha x 50 = quantity of seed per hectare
Weighed out quantity of seed for 1/100 ha x 100 = quantity of seed per hectare
Weighed out quantity of seed for 1/10 ha x 10 = quantity of seed per hectare
With deviations from the required quantity of seed, adjust the gear box according to the
Lemken calculation slide. (Picture LRS-01 and LRS-02)
During calibration a clicking noise may occur in the gear box due to the overrun clutch.
This is not a failure of the implement.
The drive clutch must always be oiled a little. Therefore lubricate it with a few drops of
oil at regular intervals.
Warning: The calculation slide contains an adjustment recommendation for the gear
box for the first calibration test. Therefore it is ensured that the first calibration
test is realistic and the required seed rate is adjusted after the second or third
calibration test. Never carry out the calibration test with switched off seed
wheels for the tramline track. If it is so, adjust the on-board computer forward
or backwards by means of the arrow keys (3) and (4).
The ha-value (or the driving distance per impulse) appears on the display of the on-
board computer LH 1600, after the working width has been encoded and the hectare
counting has been calibrated. If the calibration is done by means of driving a corre-
sponding distance on the field, the slippage of the land wheel is taken into considera-
tion.
Before first seeding the hectare-display of the on-board computer must be set to zero.
This will be done by pressing the delete key (8).
Further information see instruction book for the on-board computer LH 1600.

5.5 Calculation slide
The Lemken calculation slide replaces the seed table, which has been delivered with
each seed drill. The calculation slide shows the following functions and adjustment in-
structions:
1. Adjustment data according to the seed for the bottom flaps, the seed wheel and the
slide as well as an additional adjustment recommendation of the gear box, and that
for the first calibration test.
2. Calculation function for the determination of the seed rate (kg/ha) depending on the
thousand grain weight (g/1000) and on the required number of plants per square me-
ter (Germination is assumed to 95 %).
3. Calculation function for the gear box adjustment according to the seed rate (kg/ha)
after the first calibration test.

Example:
Seed = Wheat with a thousand grain weight of 48 g.
Required quantity of plants per square meter is 400.
1. Adjustment of the seed drill:
Position of bottom flaps = 2
Seed wheel = 1/1 (full)
Gear box adjustment for the first calibration test = 60
16

2. Determination of the seed rate:
Set the calculation slide (side 1) to 48 g/1000. Read the value kg/ha beside the line
400/m2= 202 kg/ha.
3. Carry out the first calibration test and set the result of the calibration test (for example
164 kg/ha) with the gear box adjustment of the first calibration test (= 60) on page 2
on top of the other and read the new gear box adjustment (below or above the re-
quired seed quantity 202 kg/ha) and adjust the gear box concerned = 75.
It must be ensured that the adjustment- and reading data of the Lemken calculation
slide are always on the same scale line!
A separate operation instruction in English and French language is stated on the inside
page of the calculation slide.
5.6 Seeding control
By means of the calibration test the seeding on the field will be simulated. But some
influences are not taken into account, which influence the seeding rate. In properly
cleaned seed and subsequent abrasion, for example broken ears of barley or encrusted
rape, this can reduce the seeding rate because of deposits.
As a basis for the turning of the wheel rotations/ha an average wheel slip has been as-
sumed. In practice considerable deviations upwards or downwards are possible - de-
spite the large dimensioned wheels.
Wet dressing can change the flowability of the seed. The flowability increases and this
results in larger seeding rate for a short time of operation, which then maintain a con-
stant level. In order to prevent a seeding rate deviation a new calibration test after a
short distance (about 500 m) and, if necessary, a correction of the gear adjustment has
to be carried out.
In combination with agricultural implements in particular there is the possibility of strong
vibrations which normally increase the seeding quantity.
Even if the carefully manufactured machine is used according to the guide lines, devia-
tion of the seeding rate or even a total failure are possible because of the mentioned
factors. Check your machine before and during operation for a correct and sufficient
application rate.
The most accurate test is achieved by a measured drive test. For this purpose a dis-
tance of 100 m is measured. The machine is driven along this distance at the usual
working speed. By opening the emptying flap the seed is collected in the calibration
trough. Multiply the collected quantity according to the working width.
2,50 m working width x 40,0 4,00 m working width x 25,0
3,00 m working width x 33,3 4,50 m working width x 22,2
5.7 Emptying the hopper
For emptying the hopper the calibration
trough must be folded down, the emptying
flaps opened by means of the emptying
lever (EK), the slides opened and the bottom
flap lever (EH) swung backwards so that the
left seed can run freely into the calibration
trough.
When the calibration trough is filled, the bot-
tom flap lever must be swung back again for
closing the bottom flaps. After that empty the
calibration trough.

For long periods of disuse the hopper must be emptied and cleaned. The bottom flaps
must be opened to prevent mice trying to get into the hopper and chewing at the bottom
flaps and seed wheels.
6 COULTERS
The Lemken seed drill EuroDrill is available
with standard coulters (SI) or disc coulters
(SB). It must be ensured, that the seed drill
is always lowered when in a forward motion,
in order to prevent clogging of the shares.
When delivering the implement the standard
and disc coulters are in transport position.
For adjusting the coulters into the working
position, the coulter will be lifted and the
support lever (KL) moved to the front.
6.1 Standard coulters
The standard coulters are fitted with a seed
leading system as standard, so that the seed
falls as close as possible behind the coulter
point into the seed furrow.
Coulter anti blocking flaps made out of syn-
thetic are fitted as standard. When lowering
the implement they prevent the coulters from
clogging with soil. The outer coulters, which
are also used as stands, are fitted with anti
blocking flaps made out of metal.
The overflow outlet prevents a long un-
seeded furrow when coulters are blocked.
This can appear when the implement rolls
backwards.
The coulter points can be replaced when worn.
6.1.1 Track scraper outer coulter
This coulters (SP) can also be fitted subse-
quently as special equipment and has the
advantage that the seed will be seeded in
equal depth.
When fitting this coulters subsequently the
existing long coulters must be removed and
the track scraper outer coulter will be fitted
to the frame by means of a holder. By
means of moving the coulter on the holder
the coulter will be adjusted to the correct row
distance.
The seeding depth is adjusted by means of
an height adjustment of the holder.
With harvest residues the standard coulter
can be replaced by a disc.
