Introduction
Warranty Repairs
Preface
Warranty repairs have to be submitted to the
HORSCH service department in Schwandorf via
your HORSCH distribution partner.
Requests that are processed include only those
that are filled out in full and submitted no later
than four weeks after the commencement of
damage.
Read and observe the Operation Manual before
starting up the machine. You will thus avoid
dangers, reduce the cost of repairs and down
times and increase the reliability and service life
of your machine. Pay attention to the warning
signs!
HORSCH accepts no liability for damage and
malfunctions, which result from not observing
the Operation Manual.
This Operation Manual should help you get
to know your machine and make use of the
intended areas of application. Initially, there is
a general introduction regarding the handling
of the machine. The chapters on Maintenance,
Description, Setting and Servicing are furthermore mentioned.
The Operation Manual is to be read and used
by everyone authorised to work on or with the
machine i.e.
operation (including preparation, fault repair within the working procedure, maintenance).
 Servicing (maintenance, inspection)
 transport.

You receive a spare parts list and a notice of
receipt with the Operation Manual. Field staff
will inform you about the operation and maintenance of your machine. You should then return
the notice of receipt to HORSCH. You have thus
confirmed the proper receipt of the machine. The
warranty period begins on the date of delivery.
Subject to alterations serving to improve the
machine in pictograms and details on technical specifications and weights in this Operation
Manual.
Parts delivery with used parts reclamation are
labelled "R".
Please return these components, which have
been cleaned and emptied, to HORSCH within
4 weeks together with a material defects claim
and precise description of errors.
Parts deliveries without used parts reclamation.
Retain these components another 12 weeks for
further decision.
Warranty repairs, which are carried out by
third-party companies or which are anticipated
to comprise over 10 operating hours, are to be
discussed with the customer service department
in advance.
Intended Usage

are to be eliminated immediately.

The machine should only be used, maintained
and serviced by those who are familiar with the
machine and informed of all risks.
Check your machine for the correct function and
setting before every application and also during
applications.
HORSCH has especially designed the original
spare parts and fittings for this machine. Spare
parts and fittings that are not delivered by us are
not examined and given clearance.
The installation or utilisation of third-party products can thus, among others, negatively alter
the constructively provided properties of the
machine and therefore affect the safety of people
and machines.
HORSCH is excluded from all liability for damages resulting from the utilisation of non-original
parts and fittings.
Claims for the replacement of damages, which
have not originated on the machine, are excluded. This also includes the fact that liability for
consequential damages due to seed or control
errors is also excluded.

Occupational Safety
The machine is only to be put into operation after
instruction has been carried out by employees
of the distribution partners, manufacturers'
agents or employees from HORSCH. The notice of receipt is to be filled in and returned to
HORSCH.
Only use the machine when all protective equipment and safety-related equipment such as, for
example, removable protective equipment are
available and in working order.
Regularly check nuts and screws for tight fitting and retighten, if necessary.
 Regularly check tyre pressure.
 Immediately shut down and secure the machine in case of malfunctions!

Traffic Safety
The valid road traffic regulations are to be observed when travelling on public roads, paths
and areas.
Observe permissible transport widths and install
lighting, warning and protection equipment.
Also observe transport height depending on the
coupled machine!
Pay attention to permissible axle loads, tyre
load carrying capacities and overall weights to
ensure that sufficient steering and braking capacities remain. Performance is influenced by
auxiliary equipment. Extensive overhangs and
the centrifugal mass of the auxiliary equipment
are to be taken into consideration when taking
bends.
The whole machine is to be cleaned of soil that
has been collected before transportation on
public roads
Travelling on the machine is principally prohibited!
Travel a maximum speed of 25 km/h when
being transported on public roads.
10
Accident Safety
Pay attention to the accident prevention regulations as presented by the agricultural trade associations in addition to the Operation Manual!
Coupling / Uncoupling
There is danger of injury to persons when coupling the machine to and uncoupling the machine
from the pulling tool.
Secure the machine from rolling away.
Extreme caution is to be taken when backing
up the tractor! Do not stay between the tractor
and the machine.
 Put the machine down on an even and firm
surface. Put the coupled machine down on
the ground prior to uncoupling.


On the Hydraulics
The hydraulic hoses can only be connected to
the tractor when the hydraulics to tractor and
the machine are both depressurised.
 The hydraulic system is under high pressure.
Regularly check all lines, hoses and connections for leakages and externally visible
damage!
 Only use suitable resources when searching
for leakages. Immediately remove any damage! Squirting oil can result in injuries and
burns!
 Please visit a doctor in case of injury!

Power sockets and connectors on the hydraulic
connections between the tractor and machine
should be colour-coded in order to exclude operating errors.
The control units on the tractor have
to be secured or locked in the event of
non-use or when in transport position in
order to prevent accidents through unwanted hydraulic movements or movements caused by persons other than
the operator (children, passengers).
Changing Fittings
Secure the machine so that it cannot unintentionally roll away!
 Secure lifted parts of the frame, under which
you are located, with suitable supports!
 Caution! There is danger of injury from overhanging parts (harrow, tines, coulters)!
 Do not climb onto the packer tyres or other rotating parts when climbing onto the machine.
These could rotate and you could fall and be
seriously injured.

In operation
Check the close-up range of the machine (for
children!) before starting up the machine and
before putting the machine into operation.
Make sure you have a satisfactory view.
 Do not remove any of the mandatory and
supplied protective devices.
 Stay clear of the swinging area of hydraulically
operated parts.
 Only use ascending aids and support surfaces
when machine is at a standstill. Travelling on
the machine is not permitted during operation
of the machine!

Hydraulic accumulator
An hydraulic accumulator can be installed in the
hydraulic system depending on the fittings.
Do not open or handle the hydraulic accumulator
(welding, drilling). The container is pressurised
also with gas pressure after emptying.
Empty the hydraulic accumulator when carrying
out all work on the hydraulics. The pressure
gauge should not display any pressure.
The pressure gauge has to drop to 0 bar. Only
then can work be carried out on the hydraulic
system.
11
Maintenance and Servicing








Adhere to specified deadlines or deadlines
stated in the Operation Manual for recurring
examinations or inspections.
Put the machine down on a level and solid
surface and secure it from rolling away when
carrying out maintenance and servicing
work.
Depressurise the hydraulic system and deflate or support the equipment.
Check all hydraulic lines for leakages and
loose connections after cleaning.
Check worn spots and damages. Immediately
repair already determined defects!
Disconnect the electrical system from the
power supply before carrying out any work
to this system.
Depending on machine and version with DuoDrill: Disconnect the cables from the computers and other electronic components during
welding work to the machine. Apply the weld
as close to the welded joint as possible.
Tighten loosened screw connections when
carrying out maintenance and servicing
work.
Do not wash new machines with a
steam or high-pressure cleaner. The
paint only hardens after approx. 3
months and could therefore be damaged before this time period has expired.
12
Transport/Installation
There is increased risk of accident on initial
installation. Please pay attention to the instructions in the appropriate chapters.
Delivery
The machine and auxiliary equipment is usually
delivered with a low-loader in fully assembled
condition.
If parts or assembly groups are disassembled
for transportation then they are assembled onsite by our distribution partners or our company
fitters.
The machine can be unloaded with a tractor or
has to be lifted down with suitable lifting gear
(fork lift or crane) depending on the version of
the low-loader.
Pay attention that the lifting equipment and
hoisting devices provide sufficient load bearing
capacity.
The bearing pressure and clamping points are
indicated by stickers.
Attention is to be paid to the centre of gravity and
distribution of weight for other hitching points.
These points should definitely only be attached
to the frame of the machines.
Installation
Our customer service employees or distribution partners are responsible for instructing the
operator and carrying out the initial installation
of the machine.
The owner is prohibited from carrying out any anticipatory usage of the
machine.
The machine can only be cleared for operation
after instructions have been made by customer
service employees or distribution partners and
the operating instructions have been read.
There is increased risk of accident
when carrying out installation and
maintenance work. Make yourself familiar with the machine and read the
Operation Manual before carrying out
installation and maintenance work.
Depending on scope of equipment
 Remove the bulk components supplied on
delivery from the machine.
 Check all important screw connections!
 Lubricate all lubricating nipples!
 Check the air pressure in the tyres!
 Check all hydraulic connections and hoses
for mounting and function.
 Immediately eliminate defects or have defects
eliminated.
13
Transport
The machine can be transported on public roads
either on a tractor or on a trailer or low-loading
truck depending on the regional regulations and
operating width.






The permissible dimensions and weights are
to be adhered to during transport.
The tractor selected must be large enough to
ensure that there are sufficient steering and
braking capabilities.
If the machine is hitched up as a two-point, the
lower link has to be locked to prevent against
lateral movement.
The piston rods have to be filled with spacers
when the machine is transported on public
roads and the machine is to be lowered onto
them.
The machine has to be secured on a trailer or
low-loader with straps or other supports.
Only hook the sling gear into the marked
positions.

HORSCH Tiger AS models are suitable for any
chosen working depth up to 35 cm due to their
robust construction and terra grip tool holder.
The four-bar arrangement and even tine arrangement with just 20 cm tine spacing allow
for blockage-free cultivation and ensure even
cultivation of the whole working area.
MulchMix points without wings or reversible
double points are used. The narrow shape allows for deep cultivation and a good merging of
crop residues.
A trip release system responds at approx. 320
kg trip force to prevent damage to points and
tines and reduce wear to components.

21
Tines
The TerraGrip tines are especially constructed
for the Tiger AS. They are robust and provide
precise point control as well as being suitable
for all soil types.
The points are equipped with a spring-loaded trip
release device. A trip release system responds
at approx. 320 kg trip force on every tine to prevent damage to tines, tine holder and points.
The release design of the trip release system
begins with a progressive phase and holds the
tines steady in the ground for a long period of
time.
If trip force is attained, the degressive phase
begins and the tines can easily and quickly move
upwards by up to 30 cm.
Coulters
The coulters are fitted with narrow points and
guide plates, as standard.
They are suitable for working deeper soil
depths.
They cut through the soil and merge the crop
residues into every working depth.
These parts are available in a narrow and wide
version and can be optionally combined.
Support the machine appropriately when carrying out all assembly and maintenance work to
the tines and points.

Tines
The tines can be equipped with various points
and widths for the various working depths and
soil conditions.
Maintenance:
Tighten the tool holders with 400 Nm after the
initial operating hours and after replacement.

Packer
Levelling discs
A high degree of compression and a fine, level
surface are attained by the distribution of weight
on the packer.
The discs disperse the churned up soil and level
the soil in front of the packer.
The machine is elevated into operating position
by the packer.
Disc insertions are inserted behind the tines to
ensure even levelling in all operating conditions,
working depths and speeds.
The discs are spring mounted and therefore able
to avoid stones.
Tyre packer with scraper
Scrapers are mounted between the tyres of the
packer roller. These prevent the packer tyres
from jamming and keep the interim spaces free
of stones.
Maintenance:
 Lubricate the bearings of the packer axes
which are in operation every day.
 Check air pressure of the packer tyres prior
to operation.
 Check packer and bearings for condition and
tight fitting.
Disc leveller
The working depth has to be adapted to suit the
soil conditions in the field (working depth of the
tines, working speed, amount and type of crop
residues).
23
Maintenance:
The bearings are filled with oil and therefore
maintenance-free.
Bearing for disc insertion
Regularly check the discs for play, tightness and
unlimited rotation.
Cleaning notices
The hub seals are sensitive if water permeates
them and they then have a longer period of
non-use.
Rust could form and jam both rotating part. Thus
the slide rings could rotate around the o-ring
and destroy it. The oil would escape and soon
destroy the bearing.
The bearing areas should therefore not be
washed with a high-pressure cleaner.
 The bearing areas should be sprayed with
rust dissolver or something similar before
long down times.
 The discs should be manually turned before
recommissioning and checked for unlimited
rotation.

Insert spacers on the undercarriage cylinders
and in case of the adjustable drawbar hitch
insert spacers on the front of the lifting cylinder
and lower the machine onto these supports.
In case of the adjustable drawbar hitch, connections should perhaps be initially connected in
order to adjust the height of the tow bar.
Do not transport the machine at a
higher than necessary height.
Pay special attention to the transport
height of the Tiger 6 and 8 in regard to
bridges and low electricity lines.

hitch remove spacers from the front of the
lifting cylinder and lower the machine onto
the floor.
Depressurise hydraulics and disconnect plugin couplings.
Remove plug for lighting.
Disconnect trailer connection.
When extended, the weight is distributed on all
packer wheels and the machine stands securely
on an uneven or soft surface.
This protects the tyres and prevents damage
from occurring while the machine stands during
longer down times.
When retracted, the machine should only be
put down on an even, firm surface. For this, the
machine should be lowered onto the spacers in
its lowest position.
If the Tiger AS is placed on the point
while put down on a hard surface, the
point could break off.

Depth Setting
Tiger 4 AS
The Tiger 4 AS is raised by the packer at the
rear when in operating position.
To carry out this procedure, the middle packer
is supported on the frame by the hydraulic cylinders and the side packers by means of connecting rods.
Spacers are either removed from or added to
these points in order to set the working depth.
The Tiger is raised at the front by means of the
lower link on the tractor.
Rear depth setting:
The same spacers have to be removed from
the connecting rods and hydraulic cylinders for
setting the working depth.
Working depth setting
Basic setting:
For changing for the depth setting is the same for
the connecting rods on the side packer as it is for
the hydraulic cylinder on the middle packer.
Lower the Tiger AS down onto to a level
surface.
 Fill the pressure side of the connecting rods
and the rear piston rods with the same spacers (amount and thickness).

Depth setting for connecting rod
The ratio for this amounts to approx. 1:4. i.e. If
a 1 cm spacer is removed/added the working
depth changes by 4 cm (deeper or shallower).
I.e.: Spacers of approx. 5 cm thickness have to
be removed for a working depth of 20 cm.
The spacers should not be inserted on the front
of the connecting rod.
In case of alterations to the working depth, spacers can be removed from or added to the disc
leveller. The working depth of the disc leveller
therefore remains the same.
Heavy soils:
The working depth can be set up to 10 cm
deeper at the rear than at the front with heavy
soils and if the field cultivator has a tendency
towards making rocking movements.

Tiger 5, 6 and 8 AS
Rear depth setting:
The Tiger is raised by the packer at the rear

setting.
The front depth control is carried out by means of
the lower link on the two-point tow bar and by a
hydraulic cylinder on the drawbar in the version
with the drawbar.
I.e.: Spacers of approx. 5 cm thickness have to
be removed for a working depth of 20 cm.

31
Front depth setting: Tiger 3 - 8 AS
The front depth setting is carried out on the lower
links or on the drawbar when on the field.
Lifting out at the headland
The Tiger is only lifted on the middle packer at
the rear for turning.
If the Tiger AS is run on tractor hydraulics on the
lower link, the lowest height has to be restricted
to just underneath the normal working depth as
otherwise the tractor hydraulics would lower at
the front during the lifting procedure.
Drawbar
To carry out this procedure, the field cultivator
has to be in operating position whereby the front
must be lowered during operation until the correct working depth has been attained and the
field cultivator is adjusted horizontally.
Set the lower link to tractor hydraulics in the
two-point version.
Fill the piston rods on the front hydraulic cylinders with spacers on the adjustable drawbar
hitch.
The tractor draft hydraulics have to be switched
off at the headland or the lower link will also be
lifted if there is no height restriction.
Lower the Tiger during operation until the levelling discs and packer are completely extended
and then switch over to floating position.
The working depth has to be checked
before beginning work and also in the
meantime in case of larger spaces.
32
Setting of support wheels
The Tiger AS can either be fitted with support
wheels as a standard option or they are available as an additional option depending on the
version selected.
The support wheels hold the field cultivator
steady and ensure that it maintains the same
working depth in the soil.
The wheels only act as supports and are not constructed as supporting transportation wheels.
Lift support wheel and remove adjusting bolt.
 Lower support wheel onto the ground.
 Lift support wheel and use the bolt to secure
in the next higher drill hole.
 Check setting after a few metres in operation.
 The tyres should only support the field cultivator on the soil in case of rocking movements.
The frame always has to fit perfectly on the
stop screws. The lateral wings should not be
lifted by the wheels.
Tiger 6 and 8 AS support wheel
The setting is only carried out after the depth
setting is set.
Lower the field cultivator in the soil and set the
support wheels after attaining the correct working depth.
Tiger 4 and 5 AS support wheel
33
Depth setting of coulter discs:
(does not apply to Tiger 4 foldable)
 Extend the furthest levelling discs to the working width.
 Open the stop valves on the levelling disc
hydraulics.
 Operate "Lifting" control unit and lift out disc
frame.
 Set required working depth by inserting or
removing spacers.
 Operate "Lower" on the control unit when in
the field and retract the cylinder to the stop
position.
The same spacers have to be inserted
on all cylinders.
Depth setting
The hydraulics for the levelling discs can only
be set after the depth setting is set.
The outside levelling discs have to
be retracted for transport on public
roads.
The spacers have to be removed and
the levelling discs have to be retracted
to transport width on the foldabel machines.
Depth setting for foldable Tiger 4:
Set the working depth with the adjustment
rods.
Set all rods to the same length.
34
Additional Fittings
Intermediate ring packer
The intermediate ring packer can be installed
instead of the harrow. The heavy cast-iron rings
cut up the lumps between the packer wheels.
The intermediate packer is hydraulically pressured down for effective work to be carried
out.
The accumaltors pressure is set to 50 bar by the
manufacturer. It can be set to 100 bar, if necessary, and adapted to the soil conditions.
Continue to screw in the adjusting screw
(no. 2) in order to increase pressure or unscrew
the screw to drop the pressure.
The cut-out pressure is displayed on the pressure gauge(no. 1).
If the intermediate ring packer is no longer
required, it can be locked in the transportation
position with the stop valve (no. 3).
The stop valve has been internally installed on
the wing from 2005.
Maintenance:




Intermediate ring packer
Operation:
Keep the control unit under pressure for a short
amount of time when lowering the machine.
The hydraulic accumulator fills up until it reaches
cut-out pressure (see hydr. plan). The castiron ring packer can move upwards if there are
stones or in case of soil unevenness.


Check condition and tightness of the cast-iron
rings.
Check tightness of the shaft nuts.
Loose packer wheels destroy the shaft and
the seals on the bearing. Dirt can enter and
damage the bearings.
Remove the dirt from between all components
before tightening the nuts.
Tighten shaft nut with 1000 Nm
Lubricate packer bearing.

The plate-shaped discs are screwed together
under tension with spacer discs between
them.
The tension prevents the soil from getting between the discs.
Rear draw bar
A rear draw bar can be installed to couple the
HORSCH Optipack AS or DD, for example, onto
the Tiger AS.
The scrapers ensure that the space between the
discs is kept free of crop residues.
They are fitted with slots and can be adjusted
for wear to the roller.
draw bar
The draw bar is bolted onto the rear of the main
frame.
In addition, hydraulic lines are laid at the rear
in order to hydraulically operate the towed
machine. (See hydraulics plan of respective
machine).
DoubleDisc Packer
Maintenance:
 Check packer bearings for tight fitting
 Check packer shafts for ease of rotation
 Regularly lubricate packer bearings
 Reset scrapers, if necessary
36
There is a danger of tilting when coupling an Optipack machine. Lower the
Tiger to the lowest possible position
when coupling and unhooking and do
not lift the drawbar on the Optipack to
a higher than necessary height.
Do not couple any machines to the
Tiger for travel on public roads.

Adjusting Bout Markers
The Tiger 4 - 8 models can be fitted with a bout
marker.
Stay clear of the pivoting range of the
bout markers.
There are pinching or shearing points
on all moving parts.
The bout markers have to be adjusted to the
working width during initial installation. The
marking is carried out to the centre line of the
tractor.

800 cm: 2
= 400 cm
400 cm + 11 cm
= 411 cm
Set the bout markers to 411 cm from the middle
of the outside tine.
Operation
The control unit has to be operated while the
bout markers are being extended and continued
until the bout markers are completely extended.
Then reset the control unit to neutral position.
Adjusting bout marker disc:
The bout markers can be individually set and
have to be adapted to the soil conditions.
For this, the clamping screws have to be released on the track marker arm and the shaft
has to be rotated until the required marking
depth is attained.
Maintenance:
 Lubricate the bout marker disc.
 Lubricate the pivot points on the frame.
Tiger 4 AS = 4 m
Set bout markers e.g. Tiger 4 AS
The adjustment length of the bout markers results from half the machine width plus half the
tine distance measured from the centre of the
outside tine.

DuoDrill Seeder
Tiger 4 - 8 AS machines can be fitted out with
a DuoDrill seeder for the sowing of fine seeds
like rapeseed, grass or mustard seed.
Pneumatics:
The hoses and components of the pneumatic
system have to be securely and tightly closed.
Air losses have a negative influence on the
distribution. The distributor has to be regularly
tested and cleaned for dust and deposits.
Slide valves for a tram line control system can
be added, if necessary.
Fan:
The hydraulic fan is powered directly by the
tractor hydraulics.
DuoDrill seeder
The drill comprises a 300 l seed hopper, a
pneumatic system with a hydraulic fan, injector
feeder and a distributor tower. This auxiliary
equipment is operated via DrillManager ME
electronic seeder controls (see instructions for
the DrillManager ME).
Seed hopper:
The seed hopper should always remain closed
due to dust deposits. Dust results in malfunctions
and unnecessary wear of the metering unit and
can also result in a reduction in the amount of
seed.
Venturi:
The seed is introduced into the air flow by the
fan into the Venturi. The seed is removed from
the lower cover during the calibration test. The
cover must remain closed tightly for the machine
to run in a technically perfect condition.
38
The air flow created transports the seed from
the Venturi to the seeding pipes. The necessary
amount of air depends on the seed (type and
weight) and amount of seed, working width and
sowing speed.
Requirements for the correct fan speed are
therefore not possible and have to be determined in a field test.
The air flow should not be higher than necessary.
The seed should not be blown off the metering
roller on the metering unit (see metering unit).
It should not be too weak either so that the seed
remains in the tubes and block them. There can
also be a negative effect on seed distribution if
the air flow is too weak.
The fan speed has to be adapted to the specific
application.
Approx. 2000 to 3000 r/min are recommended
for even distribution depending on operating
width and seed.
The fan setting, seed transport and
seed placement area also have to be
regularly checked at the beginning of
sowing.
The fan blade and the protective grid have to be
regularly checked for deposits and cleaned.
Deposits on the protective grid result in blockages in the seed tubes due to air losses.
Deposits on the fan impeller result in unbalances. The bearing can become overloaded
and damaged.
Fan motor
The return line has to be depressurised when
connected to the tractor!
Return pressure max. 5 bar!
Rotation speed max. 3500 r/min.
The tractor has to be equipped with a flow control valve for speed control. The spool speed is
adjusted by the amount of oil on the flow control
valve in the tractor.
8
7
The hydraulic pump has to deliver sufficient oil so that the fan speed does
not drop even in case of a drop in
the revolution speed of the tractor or
if other hydraulic functions are being
operated.
Fan motor
Checks and Maintenance
 Observe return pressure of max. 5 bar.

 Regularly clean the suction air grid so as not
to lower the air flow and thus prevent blockages.
 Clean the fan impeller of deposits so as to

Tightening fan impeller
The tapper lock on the hydraulic motor fan drive
can loosen due to fluctuations in temperature
and material wear on the fan impeller. The fan
impeller can move towards the drive shaft and
destroy the fans.
The tapper lock should therefore be
tightened after approx. 50 hours and
checked once a year.
The protective grid for the fan has to be removed
in order to carry out this procedure.
The tapper lock locates the fan and at the same
time clamps itself on the drive shaft.
Tapper lock
Pay attention to the following when tightening
the clamping screws.
The fan impeller moves towards the housing
in the direction of the protective grid when
the screws are tightened, especially in case
of initial assembly.
 A loose impeller therefore has to be aligned
closer to the hydraulic motor.
 The clamping surfaces have to be free of oil
and grease.
 The clamping screws have to be tightened
absolutely evenly and in several steps.
Tightening the flange on the cone should in
the meantime be facilitated by applying light
strokes to the flange (plastic hammer or shaft
of a hammer).

40
The imperial screws, type no. 10 - 24 4.6
should only be tightened to max. 6.8 Nm.
 The fan has to be tested for even rotation
after tightening.

Metering unit

Absolute tightness of components
has to be paid attention to when
carrying out all work on the metering
unit. Leakages result in incorrect
seed rate.
The metering housing surfaces have
to be sealed when assembling the
metering unit and the housing should
not become tight during the screwing
procedure.
41
The bottom section of the metering unit is closed
by the Venturi. In the Venturi the seed is transported by the air flow.
While calibrating, the seed is removed from
the metering unit through the opening in the
Venturi.
The cover then has to be closed securely and
tightly again.
Roller change
After selecting the roller from the table, this then
has to be fitted into the metering unit.
The seed hopper should be empty to
carry out the roller change.

42
Change roller
The setting of the sealing lip and the rotation of
the roller have to be checked after every roller
change.

 Remove retaining clip and washer from the
drive shaft.
 Push the new Metering roller on to the drive
shaft and by doing this the old rotor will be
pushed to the side of the motor.
 Refit retianing washer on drive shaft, mount
side cover and motor and refit.

Check sealing lip
A defective sealing lip or an incorrectly
mounted supporting plate results in
incorrect seed rate during sowing.
The sealing lip should not be ripped or damaged; replace if necessary.
 Insert side cover with sealing lip into metering housing. The sealing has to fit perfectly
on the rotor.

Roller for fine seeding
The rotors for fine seeding are made up of cell
wheels, spacers and the drive shaft.
The metering roller is completely pre-assembled
at the factory in order to prevent malfunctions
during the sowing of fine seeds.
Roller for fine seeding
Roller for fine seeding
Sealing lip
The holding plate for the sealing lip is asymmetrically divided.
The broad side has to face the rotor for
all normal and fine seeds.
The rotors can be mounted with either one or
two cell wheels.
The delivery volume doubles with two cell
wheels on the roller.
The cell wheels are available for a delivery volume of 3.5 cm³, 5 cm³ and 10 cm³.

positions on the housing
43
Locks that prevent against rotation have to be
rotated for clearance in the housing when assembling and disassembling the rotors.
The retaining clip should then be slid on.
In case of correct assembly of the roller, the cell
wheel between the spacers can still just about be
rotated freely. The components should not rub;
play should be kept to a complete minimum.
The gap should be just visible when checking
against the light.
Function test
After assembling the new roller, the roller has to
be checked for rotation and function.
Switch on the roller as described in the "Calibration test" section.

Assembly of roller for fine seeding
Assembly instructions:
The cell wheels and spacers are mounted with
shim washers to ensure that the seed cannot enter between the cell wheels and the spacers.
Bearings are installed in the spacers.
Shim washers are inserted depending on the
manufacturing tolerance so that the cell wheels
cannot rub against the spacers.
Seed rates become incorrect if rotations are not evenly balanced and the
motor can become overloaded.






Roller for fine seeding
After all components have been assembled, the
space remaining up to the retaining clip is filled
with shim washers.
44
The drive motor has to run on smoothly.
No mechanical friction should be able to be
heard.
If possible, determine mechanical friction.
Revise or renew damaged parts (grind, dress
to size ...).
Release screws for drive motor and roller
bearing on side covers and realign side covers in order to release tensions.
Realign or renew drive shaft, if bent.
If foreign bodies are stuck between the rotor
and housing - remove the foreign bodies
If dust has got in between the cell discs and
spacers - disassemble the roller and clean.
Rapeseed brushes
The rapeseed brushes clean the cell wheels in
the roller for fine seeding.
The rapeseed brushes have to be installed in
the side cover and checked for function prior to
the sowing of fine seeds.
Metering unit with injector feeder
The metering unit in machines with a normal
hopper and injector feeder are equipped with a
V2A cover with milled edges.
Negative pressure is created on the injector
nozzle during operation. Additional air is fed into
the air flow through this V2A cover.
Installed rapeseed brushes
Check rotation and mounting.
Check condition and cleaning impact of
brushes.
 Insert side cover with brushes into metering
housing.
 The brushes have to fit perfectly on the cell
wheels and rotate with the roller.


Function and cleaning impact of the
rapeseed brushes have to be regularly
checked before the beginning of sowing
and if there are large surface areas.
Sticky cell wheels result in incorrect seed rates
during sowing. Less seed is actually metered.
Metering unit with cover for injector nozzle
The setting of the injector nozzle with the cover
works up to a potential maximum amount of
seed.
If this amount is exceeded, dynamic pressure
appears on the injector nozzle. This means that
seed can be blown out through the perforated
plate, which results in an excess of seed of seed
in the middle of the machine.
These grains are visible on the surface of the
field before they are covered by the packer or
harrow.
The side cover with the rapeseed brushes can
be removed if the seed hopper is full.
Sticky cell wheels can therefore be cleaned while
still installed in the machine.
The rapeseed brushes should be disassembled
when using normal seeds. The housing bolt
holes have to be filled.

Maintenance and
Servicing
Observe the safety instructions for
maintenance and servicing.
Your machine has been designed and constructed for maximum power, efficiency and
user-friendliness according to a multitude of
operating conditions.
Your machine has been checked at the factory
and by your appointed dealer prior to delivery in
order to determine that the machine is in perfect
condition. The recommended maintenance and
servicing work should be carried out at regular
intervals in order to maintain failure-free operation.
Cleaning
The recommended cleaning and maintenance
work should be carried out at regular intervals
in order to maintain operational availability and
guarantee optimum performance.
The hydraulic cylinders and bearings
should not be cleaned with a high-pressure cleaner or direct water jet. The
seals and bearings are not waterproof
under high pressure.
Maintenance Periods
The maintenance intervals are determined by
various different factors.
Various operating, weather and soil conditions
as well as working speeds affect the maintenance intervals, but also the quality of the
lubricants and cleaning agents used determines
the time interval required until the next period of
maintenance work.
The specified maintenance intervals can therefore only be regarded as an indication.
The intervals of maintenance work affected
have to be adjusted to suit the conditions shoud
there be any deviations from normal operating
conditions.
Regular maintenance forms the basis for a serviceable machine. Serviced machines lower the
risk of malfunctions and guarantee the efficient
application and operation of machines.
Storage
Should the machine be shut down for a longer
period of time:
if possible, store machine under a roofed
area.
 protect the machine against rust. only spray
with biologically degradable oils i.e. rape oil.
 relieve the strain from the wheels.

47
Lubricating Machine
The machine should be lubricated regularly and
after every pressure wash.
This ensures operational reliability and reduces
the costs of repair work and down times.
Hygiene
When used according to regulations, lubricants
and mineral oil products present no danger to
health.
You should, however, avoid longer contact to
the skin and not breathe in any fumes.
Exposure to Lubricants
CAUTION:
Avoid direct contact with oils by wearing gloves
or protective creams.
Thoroughly wash off traces of oil on the skin with
warm water and soap. Do not clean your skin
with petrol, diesel fuel or other solvents.
Oil is poisonous. You should immediately visit
your doctor if you have swallowed oil.









Ensure that lubricants are kept out of reach
of children.
Never store lubricants in open or unlabelled
containers.
Avoid skin contact with oily clothes. Change
dirty clothing.
Never keep oily cloths in your pockets.
Dispose of oily shoes as hazardous waste.
Rinse oil that has splashed into your eyes
with clean water and visit your doctor, if necessary.
Absorb spilt oil with suitable bonding agents
and dispose of.
Never extinguish oil fires with water. Only use
permissible and suitable extinguishing agents
and wear breathing apparatus.
Oily waste and waste oil have to be disposed
of according to the legal regulations.
