1. INTRODUCTION
1. INTRODUCTION
INTENDED USE
The precision chop forage harvester FC 855 is solely constructed and
manufactured for the usual work in agriculture, i.e.: Usual work in fields where
you want to cut/gather and chop green crops such as grass or whole crop, which can
be picked up from swaths, which are to be used for silage production intended for
coarse fodder for cattle.
The machine should only be connected to a tractor which corresponds with the
specifications of the product and is legal to use.
Any use beyond this is outside the intended use. JF-Fabriken A/S is not
responsible for any damage resulting from such use, the user bears that risk.
It is assumed that the work is performed under reasonable conditions, i.e. that the
fields are cultivated normally and to a reasonable extent kept clear of foreign matter
and the like.
Intended use also means that the instructions given by JF- Fabriken A/S in the
instruction manual and the spare parts book are observed and that thorough
agricultural knowledge and technically correct use is a matter of course.
The precision chop forage harvester FC 855 should only be used, maintained
and repaired by persons who, through relevant instructions and after reading
the instruction manual, are familiar with the machine and, in particular, are
informed of possible dangers.
In the following there are a number of general and special safety instructions which
must be observed altogether.
If changes are made on the machine and its construction without permission from JFFabriken A/S, JF-Fabriken A/S cannot be held responsible for any damage resulting
from this.
PERFORMANCE
The FC 855 is capable of working alone or parallel with other machines.
FC 855 has a high capacity compared with other corresponding products as it uses
the “UPPER CUT” system. “UPPER CUT” gives a minimum loss of power when
cutting the material and thus ensures maximum utilisation of the accessible tractor
power.
Capacity, however, is difficult to define and compare as, for a forage harvester, it will
depend not just on which crop is being cut but also how the crop has been treated
before it is picked up or cut by the machine and finally which cutting length
adjustment the machine is working with.
PIGB-138X-02 FC 855 0410
- 6 -
1. INTRODUCTION
If we take a forage harvester which, in fresh, not pre-dried grass, can work 100 tons
per hour, it is possible to calculate the capacity at different per cents of dry matter
depending on the pre-treatment before cutting, as shown in the following table.
Dry matter Capacity
Dry matter 100% 18 ton/h
Wet new grass 15% 120 ton/h
Not pre-dried grass 18% 100 ton/h
Pre-dried grass – no outflow of sap from clamp
silo
25% 72 ton/h
Pre-dried grass – no outflow of sap from high
tower silo
33% 55 ton/h
Very pre-dried grass 50% 36 ton/h
Straw, very dry 90% 20 ton/h
It will probably surprise most people that the capacity can vary between 20 and 120
ton/h, as a result of varying water content.
In practice you want to drive the forage harvester in the highest possible tractor gear
without causing frequent blockage. However, the amount of grass in the field will
always vary, for instance where the mower conditioner has had to turn, change
forward speed or change direction of travel. Therefore it is often appropriate either to
drive with a power reserve so that the machine will not block, or to continuously
adapt the driving of the forage harvester to the conditions.
The pick-up unit and the feed rollers are both secured against overloading resulting
from a blockage by means of a friction clutch. The forage harvester also has a
reverse function which makes it possible to remove a blockage without having to
leave the tractor seat.
The intention is that the inexperienced user increases the forward speed gradually in
the beginning until the pick-up is blocked; releases the blockage again by reversing
and chooses a tractor gear at a suitable lower level to reduce the risk of blockage.
However, it is not the intention that the clutch function of the feed rollers releases. If
this happens, the clutch adjustment of the pick-up must be reduced. The same will
apply if the main friction clutch between the tractor and the machine releases during
normal working. If it is not the pick-up unit which is blocked, the adjustment of the
machine is incorrect.
Unfortunately it has been seen before that the torque adjustment of the friction clutch
of the pick-up unit has been increased to the point where it is the friction clutch
between the machine and the tractor which releases frequently. The main friction
clutch is not intended to release frequently but only for starting shock or when foreign
matter gets into the machine. The same applies to the friction clutch for the feed
intake rollers. The main clutch simply cannot absorb the heat which is generated
during these long releases. The power transmitted at the main clutch will be at least
10 times higher than the power needed to drive the pick-up unit.
Only the pick-up unit can be seen from the tractor and therefore it should be released
first when there is a blockage. The experienced user will be able to adapt the driving

1. INTRODUCTION
of the tractor to the amount of grass and thus work with less capacity reserve and, all
other things being equal, have a greater output.
The cutting length of the forage harvester can be adjusted and adapted to the crop in
question. The cutting length is usually reduced when cutting whole crops to ensure
greater damage of the grains. The shorter cutting length will of course require more
power for which reason there will be a lower output when cutting whole crop than
when cutting grass, though it is difficult to compare.
The power requirements are also increased when the blades are worn and the
shearbar adjustment thereby changes. It is necessary to sharpen the blades and
adjust the shearbar during the season.

1. INTRODUCTION
SAFETY
The safety of persons and machines is an integral part of JF-STOLL’s development
work. However, damage can occur as a consequence of misuse and insufficient
instruction. We wish to ensure the safety of you and your family in the best
possible way, but this also requires an effort on your part.
A forage harvester cannot be constructed in such a way that it guarantees the full
safety of persons and at the same time performs an efficient piece of work. This
means that it is very important that you as user of the machine pay attention and use
the machine correctly and thereby avoid exposing yourself and others to
unnecessary danger.
As already mentioned the machine is only intended for one purpose, namely:
Chopping of grass and similar green crops, for feeding purposes.
It is assumed that the work is performed under reasonable conditions, i.e. that the
fields are cultivated normally and to a reasonable extent kept clear of foreign matter
and the like.
The machine demands skilled operation, which means that you should read the
instruction manual before you connect the machine to the tractor. Even though
you have been driving a similar machine before, you should read the manuals - this
is a matter of your own safety!
You should never leave the machine to others before you have made sure that they
have the necessary knowledge.
DEFINITIONS
The safety decals and the instruction manual of the machine contain a line of safety
notes. The safety notes mention certain measures, which we recommend you and
your colleagues to follow as to increase the personal safety as much as possible.
We recommend that you take the necessary time to read the safety instructions and
inform your staff to do the same.
In this instruction manual this symbol is used with reference to
personal safety directly or indirectly through maintenance of the
machine.
CAUTION: The word CAUTION is used to ensure that the operator follows the
general safety instructions or the measures mentioned in the
instruction manual to protect himself and others against injuries.
WARNING: The word WARNING is used to warn against visible or hidden risks,
which might lead to serious personal injuries.
DANGER: The word DANGER is used to indicate measures which, according to
legislation, must be followed to protect oneself and others against
serious injuries.

1. INTRODUCTION
GENERAL SAFETY INSTRUCTIONS
The following is a brief description of the measures, which should be a matter of
common knowledge to the operator.
1. Always disengage the PTO drive shaft, activate the parking brake and stop the
tractor engine before you
- lubricate the machine,
- clean the machine,
- disassemble any part of the machine,
- adjust the machine.
2. Always block the wheels before working under the machine.
3. Never start the tractor until all persons are safely away from the machine.
4. Make sure that all tools have been removed from the machine before starting
the tractor.
5. Make sure that all guards have been mounted correctly.
6. During work never wear loose clothes or have your hair hang down as it may be
pulled in by the moving parts of the machine.
7. Always wear suitable shoes to avoid falling.
8. Do not change the guards or work with the machine when a guard is missing or
defective.
9. Always drive with the statutory lights and safety marking during transport on
public road and at night.
10. Limit the transport speed to maximum 30 km/h if the machine has not been
marked with another maximum speed limit.
11. Do not stand near the machine while it is working.
12. When mounting the PTO drive shaft check that the number and direction of
RPM of the tractor matches those of the machine.
13. Always use hearing protectors if the noise from the machine is annoying or if
you are working with the machine for a considerable period in a tractor cabin,
which has not been silenced sufficiently.
14. Never allow anybody to be on the machine during work or transport.
15. Never use the machine for other purposes than what it has been constructed
for.
16. Do not allow any children to be near when you are working with the machine.
PIGB-138X-02 FC 855 0410
- 10 -
1. INTRODUCTION
17. Never stand between the tractor and the machine during connection and
disconnection.
18. Do not feed material into the cutting unit, using hands or feet, while it is working.
19. Do not try to remove material from the cutting unit while it is working.
20. If material must be removed from the forage harvester, the PTO shaft must be
disconnected completely. If in doubt stop the tractor engine before removing
any material from the forage harvester.
LOCKING OF GUARDS
All hinged guards on the machine are equipped with a lock. The lock ensures that the
guard cannot be opened without tools. There are two different types of lock. Fig. 1.1
and 1.2 show the two locking principles and the corresponding transfers which
indicate and illustrate the locks on the machine.
Fig. 1-1
Fig. 1-2
CHOICE OF TRACTOR
Always follow the recommendations specified in the instruction manual of the tractor.
If this is not possible, technical assistance must be sought.
Choose a tractor which has minimum 55 KW/75 HP at the power take-off but cannot
deliver more than 92kW/125 HP.
The machine is as standard constructed for 540 RPM or 1000 RPM, and is delivered
from the factory with 1 3/8" PTO drive shaft with 21 splines yoke. As an alternative 1
3/8’’ yoke with 6 splines can be supplied for the PTO drive shaft of the machine
A suitable tractor will have a good range of gears for driving speeds between 5 and 8
km/h.
The tractor hydraulic system should deliver at least 170 bar and the adjustable relief
valve should not allow more than 210 bar.
The following hydraulic outlets are necessary depending on the equipment used:
1 Single-acting Drawbar
1 Double-acting Hitch, adjustable (option)
PIGB-138X-02 FC 855 0410
- 11 -
1. INTRODUCTION
It is important that there is direct access to the 12-volt battery of the tractor and that it
is in a good condition.
Always choose a tractor with a closed cabin when working with a precision chopper.
CONNECTION AND DISCONNECTION
Always make sure that nobody is standing between
the tractor and the machine during connection and
disconnection. An unintentional manoeuvre with the
tractor may cause serious injury (see fig. 1-3). When
disconnecting it is important that the ground is even
and stable so that the machine does not move and
injure persons or cause damage to other equipment.
PR80-0804
Check that the machine is intended for the number
and the direction of rotation of the tractor PTO. (see
figure 1-4). A wrong number of rotations over a long
period may damage the machine and at worst result
in ejection of parts through the delivery chute.
Make sure that the PTO drive shaft has been
mounted correctly, i.e. that the lock pin is in mesh and
that the support chain has been fastened at both
ends.
Fig. 1-3
Fig. 1-4
The PTO drive shaft must be correctly protected. If the guard is damaged it must be
replaced immediately.
Check that all hydraulic couplings are tight and that all hoses and fittings are
undamaged before activating the hydraulic system.
When parking the machine and after the tractor engine has stopped make sure that
there is no pressure in the hydraulic hoses by activating the tractor hydraulic spool
valves.
Hydraulic oil under pressure can penetrate the skin
and cause serious infections. You should always
protect the skin and the eyes against oil splashes
(see fig. 1-5). If, by accident, hydraulic oil under
pressure hits you, consult a doctor immediately.
Fig. 1-5
PIGB-138X-02 FC 855 0410

1. INTRODUCTION
ADJUSTMENT
IMPORTANT: Before adjusting the machine, always:
- Disengage the PTO from the tractor.
- Stop the tractor engine
- Wait until all moving parts have stopped.
It is important not to remove the guards until all revolving parts have stopped. This
especially applies to the delivery chute above the blade cylinder.
If the cutting parts in the blade cylinder must be adjusted or replaced, it is important
to block the blade cylinder as the sharp blades can easily cause injury.
Before working check that the feed rollers and the blade cylinder can move freely.
Also check that the blades are intact and without cracks. Damaged blades must be
replaced to prevent them from blocking or damaging the machine and to avoid metal
parts being thrown out from the delivery chute.
Check periodically if blades and blade bolts are worn according to the rules in the
instruction manual.
The first time you use the machine the blades and blade bolts may "bed in". For this
reason you must check and tighten the blade bolts after the first working hour.
When lifting the delivery chute above the blade cylinder make sure that nobody is in
danger of being hit by the guard. When lifting the guard, hold on to the hoop which is
fastened to the intermediate guard with both hands.
TRANSPORT
Limit the transport speed to maximum 30 km/h if the machine has not been marked
with another maximum speed limit.
Always check that mechanical transport safety devices are activated before transport
with trailed implements.
PIGB-138X-02 FC 855 0410
- 13 -
1. INTRODUCTION
Fig. 1-6
Fig. 1-6 The attachments of the forage harvester (pick-up etc.) must be secured mechanically
before transport.
The statutory lighting and traffic markings must be placed correctly, on the forage
harvester as well as the trailer.
Reflectors and lighting must be cleaned regularly.
WORKING
Before you start working make sure that no persons are behind the forage harvester
due to the danger of being hit by metal parts from damaged blades.
Also make sure that there are no persons in the trailer used for picking up. There is
danger of suffocating in the flow of material or getting hit by metal parts.
If the feed rollers or the blade cylinder are blocked, disengage the clutches and stop
the tractor engine immediately. Activate the parking brake and wait until the revolving
parts have stopped before removing the material or the foreign matter.
Unfortunately, this cannot be said too often: Never remove material blocked in the
machine while the machine is running and never feed material into the pick-up with
your hands or feet as there is a serious danger of getting caught and pulled into the
harvester which would cause dismemberment or death.
Therefore, never allow anyone to stand near the forage harvester while it is working,
especially not children who do not know the danger and do unforeseen things.
PARKING
Remember to block the wheels if there is a risk that the machine will move after
parking.
Remember to remove the hydraulic hoses before driving away with the tractor.
GREASING
When greasing or maintaining the machine never let more than one person work at
the machine at a time. This reduces the risk of getting fingers caught because
PIGB-138X-02 FC 855 0410
- 14 -
1. INTRODUCTION
another person by accident turns the revolving parts while you are still working with
them.
Never try to clean, grease or adjust the machine before the PTO has been
disengaged, the tractor engine has stopped and the parking brake been activated.
GRINDING
When grinding always follow this procedure:
- Stop the tractor engine.
- Activate the parking brake.
- Wait until all moving parts have stopped.
Unfortunately it is necessary to remove some of the guards to change the direction of
rotation of the rotor when grinding the blades. As there are chain and belt
transmissions your hands may be injured if the revolving parts have not stopped
before the guards are removed.
Grinding is performed according to the following procedure:
1. Check if the grindstone is undamaged and if the device is able to move back
and forth easily.
2. Lower the guard behind the grinding device to give access to the blade cylinder.
3. Adjust the stone and guard the grinding device again.
4. Remove the guard above the blade cylinder transmission and change the
direction of rotation of the rotor.
5. Fasten the guard again and check that there are no persons near the machine.
6. Start the tractor again and keep the rpm close to idling.
7. Perform the grinding carefully.
Always use safety glasses when grinding as small particles from the grindstone might
hit you.
When grinding has finished, stop the tractor engine, change the direction of rotation
and fasten all guards.
REMEMBER: Only grind with all guards closed!
MAINTENANCE
After approx. 2 days of operation all bolts must be re-tightened, especially the blade
bolts of the blade cylinder.
Always make sure that the used spare parts are tightened to the correct torque.
Hydraulic hoses must be checked by an expert before use, and after that minimum
once a year. If necessary, they must be replaced. The working life of hydraulic hoses
should not exceed 6 years, including maximum 2 years of storage.
PIGB-138X-02 FC 855 0410
- 15 -
1. INTRODUCTION
When replacing, always use hoses which comply with the requirements stated by the
manufacturer. All hoses are marked with date of production.
REPLACEMENT OF WEARING PARTS
Blades, blade bolts and shearbar are made of high-alloyed, heat-treated materials.
This heat treatment provides especially hard and ductile material which is able to
withstand extreme stress. Damaged blades, blade bolts or shearbars must be
replaced by original JF-STOLL spare parts to ensure safe operation.
PR11-0232
Min. 12 mm
Blades and blade bolts must be checked every day
during the season.
The special blade bolts must be tightened with a torque
wrench to 40 kgm.
When the blades have been worn max. 8 mm or
approx. 12 mm above the straight piece, they must be
replaced (see fig. 1-6).
Fig. 1-6
After replacement of blades, blade bolts and the like,
check that no tools have been left in the machine.

1. INTRODUCTION
SAFETY DECALS
The safety decals shown on the previous page are positioned as shown on the drawings on the
opposite page. Before using the machine, check that all decals are present: if not, require those
missing. The decals have the following meaning:
1. Read the instruction manual and the safety instructions.
This is to remind you to read the delivered documents to ensure the machine is operated
correctly and to avoid unnecessary accidents and machine damage.
2.
Stop the tractor engine and remove the ignition key before touching the machine.
Always remember to stop the tractor engine before lubricating, adjusting, maintaining or
repairing. Also remember to remove the ignition key to ensure that nobody starts the engine
until you have finished
.
3. Children.
Never let children stand near the machine during operation. Especially not small children as
they have a tendency to do unforeseen things.
4. Chain drive
One or more chain drives are placed under this guard. Make sure that the tractor engine has
stopped before opening the guard.
5. Risk of cutting.
There is a risk of getting fingers etc. caught several places on the machine. Be careful when the
machine is connected to the tractor and ready to work. The machine can easily crush or cut off
any part of the body that might get caught in the machine.
6. Remember the guards when grinding.
Remember to close ALL guards before grinding.
7. Rotating parts.
After the PTO drive shaft has stopped, the blades will have a momentum where they keep
rotating for up to 2 minutes. Wait until the blades have come to a complete stop before
removing guards for inspection or maintenance.
8. Risk of getting pulled into the machine
Do not stand near the attachments or the feed rollers while the machine is running. Make sure
that the tractor engine has stopped first.
9. The number and the direction of rotations.
Check that the PTO drive shaft runs with the right RPM and in the right direction. A wrong
number of rotations and/or direction of rotation can damage the machine with the risk of
personal injury as a result.
10. Maximum 210 bar.
Make sure that the hydraulic components are not exposed to more pressure than maximum 210
bar as there could be a risk of explosive damage of parts. Hereby you expose yourself and
others to serious danger of getting hit by metal parts with high speed or oil under high pressure.
11. PTO drive shaft for rotor.
There is an alternative pin for the PTO drive shaft for the rotor. It is used when the rotor is
disconnected during reverse and when the rotor rotates in the opposite direction during
grinding. Make sure that you place the PTO drive shaft correctly on the pin when performing
these operations.
12. Remember the transport lock.
Always remember to check the transport lock before transporting the machine on public road.
Errors in the locking system and unintended manoeuvres may cause the machine to move to

Connect the 2-pole socket C on the power supply cable to the instrument board in
case such a socket is not already mounted in the cabin. Connect the cable directly to
the tractor battery, connecting the cable with the fuse box to + (plus) on the battery
(remember that the fuse must be placed near the battery).
The 2-pole plug from the control panel can now be connected to the power supply
cable.
CAUTION: It is very important for the functioning of the electric system that there
is a good connection to - (negative/earth) and + (plus) on the battery.
We advise you not to connect to for instance the wiring of the lights
as the wire thickness for these systems is usually not sufficient to
transfer the necessary power.

MOUNTING OF LIFT SUSPENSION
PR11-0354
Fig. 2-5
Fig. 2-5 The suspension is mounted in the 3-point suspension of the tractor and is mounted
so that it is as close to the rear wheels of the tractor as possible. This gives the most
stable driving and the load on the link arms is reduced.
Both link arms must have the same oblique position in relation to the middle position
in order to keep the suspension parallel with the tractor. After correct mounting of the
suspension the PTO shaft is mounted.
Fig. 2-6
Fig. 2-6 The PTO of the tractor and the PIC (Power Intake Connection) of the machine must
be parallel, i.e. the angle between them must be as close to 0º as possible. The
suspension is adjusted so that the PTO shaft in working position is maximum 10°
higher or lower than horizontal. This corresponds to the PIC (input shaft of the
gearbox), being maximum 100 mm higher or lower than the tractor’s PTO.
The lift suspension is as standard equipped with hitch hook. For connection of trailers
with clevis drawbar the plate is placed with the hitch hook facing forwards and the
hole on the intermediate plate for clevis drawbar facing backwards.

before the PTO shaft is reassembled.
F. On the PTO drive shaft between the 3-point suspension and the machine there
is a friction clutch which ensures that the machine is not overloaded during
operation. Before starting a new machine, the clutch must be "aired". See
section concerning the friction clutch in chapter 6 "MAINTENANCE".
G. The 3-point linkage frame is mounted in the lift arms of the tractor. The L-frame
hoop 3 is pushed onto the 3-point linkage frame 5.
You should read and observe the instructions in the instruction manual for your
tractor as regards connection of implements in the tractor hydraulics. You should be
especially aware of the fact that if the tractor hydraulics is with weight transfer that is
activated by the top link fix point, the weight transfer must be put out of action or the
top link must be connected to a firm top point on the tractor. If the weight transfer is
not put out of action, the link arms may begin to lift even if the control handle is not
activated. The weight transfer may also cause the link arms to move heavily up and
down.

CONNECTION AND DISCONNECTION OF
PRECISION CHOPPER
Fig. 2-10
Fig. 2-10 The 3-point linkage frame is lowered and you drive towards the machine until the ball
joint on the L-frame hits the edge of the catch. Thereby the suspension is lifted and
the machine is connected in the front point.
Then you drive a little forward and put the tractor wheels straight until the pawl at the
outside of the suspension is engaged with the machine.
The PTO shaft is released from the holder and is attached to the bevel gear shaft.
The chute control system is fastened in the tractor and the machine is ready for use.
Disconnection takes place by first removing the chute control system and the PTO
shaft from the tractor. After that the 3-point linkage frame is lowered until the machine
rests on the ground. Now the locking pawl in the front attachment point is released by
pulling the cord. When the 3-point linkage frame is raised again while pulling the
cord, the machine is released from the frame and you can drive away from the
machine. If the pawl cannot be released the length of the wire must be checked.
When driving away make sure that the trailer goes clear of the precision chopper.
Please note! The machine must be low ered to the ground before the locking
pawl can be released.

Fig. 4-1 The pick-up is equipped with support rollers made of steel which are adjustable in
height. You should keep the pick-up at such a height that the tines do not hit the
ground and leave earth in the crop and can pick up the grass without waste.
JF-STOLL recommends a distance between the pick-up tines and the ground of 15 to
20 mm.
Fig. 4-2
Fig. 4-2 With the spindle A the relief springs are tightened, so that the pick-up will have a
maximum pressure towards the ground of 30 kg. Check this by standing in front of
the pick-up and pull the hoop upwards and estimate the ground pressure. When the
machine stands on even ground, the limiting rod B must be in the middle position so
that the pick-up can move freely a bit up and down and thereby follow the ground.

4. ADJUSTMENTS
Fig. 4-3
Fig. 4-3 The adjustment is made at the opposite side at the hydraulic cylinder of the
suspension as shown on figure 4-3.
The auger on the pick-up is equipped with a slip clutch. The slip clutch of the auger is
adjusted so that it releases before the other friction clutches in the machine.
The highest capacity is obtained by working at a forward speed where you drive
without blockage in the auger. If there is a blockage around the auger you stop and
force the crop out of the machine by means of the reverse function. See also chapter
5 "DRIVING IN THE FIELD".
A continuous and even flow through pick-up and auger is the best way to avoid
blockages inside the machine, otherwise more operational stoppages may occur.
The operator should always ensure spare friction discs for the slip clutch on the
auger are in the tool box. If this clutch has often been in operation, the coating of the
friction discs is worn and it cannot transfer sufficient transmission. It may therefore be
necessary to replace the friction discs, but remember they have to be of the same
number and quality.

REPLACEMENT AND ADJUSTMENT OF BLADES
When replacing a single blade the blade must be placed at the same distance from
the shearbar as the other blades. To ensure that the rotor is in balance it may be
necessary to replace the opposite blade as a used blade has a different weight
compared to a new blade.
Even if there is no visible damage to the blade bolts, they should always be replaced
together with the blades as they might have been overloaded.
CAUTION: Check the distance between the blade and the shearbar (0.5
mm) with the supplied gauge before and after the bolts are
tightened.
WARNING: Only use original blade bolts when replacing. Tighten the blade
bolts with a torque wrench to 400 Nm (approx. 40 kpm) or with
the supplied spanner using approx. 40 kg leverage (400 Nm).

GRINDING
Adjustment of the PTO drive shaft for the rotor to or from grinding position,
respectively, may only take place when the machine has been stopped and the

grinding device is in grinding position.
Check before grinding:
- that the grindstone is undamaged.
- that the device is easily sliding back and forth.
- that the device is parallel with the rotor.
The grinding device is correctly adjusted from the factory and therefore there is
normally no need for adjustment, but if it has been dismounted adjustment can be
made at the oblong holes of the lateral guides. The bolts must be tightened firmly
after the adjustment.
The stone is fed by turning the handle.
Normally you should grind the blades once a day – but avoid too much grinding.
CAUTION: Protect your eyes – always use safety glasses when grinding.
The guard above the grinding device must be closed while

5. DRIVING IN THE FIELD
5. DRIVING IN THE FIELD
GENERAL CONDITIONS
Adjust the machine to the maximum cutting length acceptable for the crop in
question. This will reduce the stress in the feed intake section and the transmission
and increase the possibility of working with the machine continuously without
blockages.
Always work with sharp blades and correctly adjusted shearbar. Be aware that an
adjustment for short cutting length not only demands increased power but also
causes increased wear of blades.
PR12-0471
A
Fig. 5-1
Fig. 5-1 The feed intake plate A above the pick-up should be dismounted when working in
heavy and strong crops as the auger can easily pull the crop into the feed intake
section under such conditions. At the same time you will have optimal preconditions
for problem-free reverse out of the auger as the feed intake plate A usually tends to
prevent the crop from being reversed freely out of the auger.
Under difficult conditions we recommend you to bring spare friction discs for the slip
clutch on the auger as the pre-adjusted torque on a slip clutch falls gradually when it
is activated and the wanted power cannot be transmitted. When replacing discs
remember that they must be of the same number and quality so that the wanted
torque can be transmitted and to secure maximum life.
SWATHING BEFORE CHOPPING
If it is possible to influence the swathing made before chopping it is important to
emphasise that regular and even swaths are optimal for the subsequent chopping
and will spare the tractor driver a lot of trouble.

TRANSPORT POSITION
PR11-0358
Fig. 5-2
Fig. 5-2 The machine is connected so that it follows behind the tractor. Make sure that the
safety pin is in mesh before driving on public road.
When driving on public road the delivery chute must be in a position where it does
not increase the transport width of the machine.
STARTING AND WORKING IN THE FIELD
Do not approach the machine until the blade rotor has come to a complete
stop.
STARTING
Gradually increase to the correct number of rpm - 540 or 1000 rpm on the PTO.
Drive slowly into the crop and increase the forward speed as long as the tractor can
keep the required number of revolution of approx. 540 or 1000 rpm.
An inexperienced operator should always work with a capacity reserve in the
machine to avoid problems with the flow through the machine.
IMPORTANT: Always make sure that the tractor can keep the correct number
of revolutions of 540 / 1000 rpm on the PTO. This ensures a
regular load of the machine and you avoid torque increases (in
case of reduced rpm) which wears the safety clutches and the
transmission.
To obtain optimal pick-up function it is important that:
• The crop enters the machine regularly and that you, if possible, drive in the
opposite direction of the mower conditioner.
• The forward speed is adjusted to the amount of crop and is not so high that
blockage is frequent.
PIGB-138X-02 FC 855 0410

5. DRIVING IN THE FIELD
• You drive as straight as possible into the crop and are aware of this when
turning in the field.
Fig. 5-3
Fig. 5-3 The pick-up is fitted with support rollers of steel which are adjustable in height. From
the factory the wheels have been adjusted so that there is 15-20 mm space between
the tines and an even and firm ground.
Check regularly that the pick-up tines do not reach further down than necessary to be
able to pick up the swath efficiently. If the tines hit the ground too hard they are
quickly worn and the drive of the pick-up may be overloaded.

Auger and feed intake section:
In case of blockage in the auger or feed intake section, activate the reserve function
immediately and reduce the number of revolutions.
Hereby the auger and the feed intake stop immediately, and you can obtain an
overview of the situation.
Now place the reverse system in reverse position at a low number of rpm, with the
switch on the panel, and reverse the material out of the machine. We recommend to
reverse slowly with the machine when the material is pushed out. Thereby you avoid
accumulation of material behind the pick-up auger and in front of the pick-up fingers.
After reversing move the reverse system back to normal feed intake at a low number
of rpm. When the machine runs correctly, increase to correct number of rpm, and the
work can be resumed.
The rotor
In case of blockage in the rotor, activate the reverse function immediately and turn
off the power transmission.
To enable the feed rollers to pull the material out of the rotor, it must be disconnected
during reverse. The procedure is as follows:
1) Go to the machine when the power take-off is disconnected and the engine has
been stopped.

Fig. 5-5 gear wheels are not in mesh. Thereby the rotor is not driven.
WARNING: It is important that the PTO shaft is NOT moved to pos. 2, where
the rotor rotates in the opposite direction. This position is used
for grinding, or for reverse in case of blockage in the auger or
the feed intake section.
3) Connect the power take-off again at low number of rpm and move the reverse
function to reverse position with the toggle switch on the control panel and
reverse the material out of the machine.

6. MAINTENANCE
FRICTION CLUTCH
Fig. 6-3
Fig. 6-3 In order to ensure a long life for your tractor and machine, the machine is delivered
with a friction clutch on the PTO drive shaft from the bevel gearbox to the machine
and on the driving mechanism for the feed rollers. The figure illustrates how the
clutch protects the transmission against high torque peaks and at the same time is
capable of transmitting the torque while it is in function (slips).
The auger is also fitted with a friction clutch as described in the section PICK-UP in
chapter 4 "ADJUSTMENTS".
The friction clutches must be maintained at regular intervals. At the same time, the
clutches must be checked if they have not been in operation for some time. This
especially applies after winter storage before the machine is used for the first time in
the season.
Maintenance of the friction clutch on the PTO drive shaft:
Fig. 6-4
Fig. 6-4 Before the start of a new machine and after a long period of standstill, e.g. winter
storage, the clutch is "aired" in the following way:
PIGB-138X-02 FC 855 0410
- 50 -
6. MAINTENANCE
The six nuts on the flange are tightened. Hereby the springs are compressed so that
they do not press on the clutch plates and the clutch can rotate freely. Have the
clutch rotate for half a minute to remove dirt and possible rust on the plates.
The nuts are loosened again until they are at level with the threads of the bolts, and
the springs can press on the clutch plates.
Maintenance of the friction clutch on the auger:
PR12-0708b
A
C
B
D
Fig. 6-5
Fig. 6-5 1) Disassemble the clutch and clean all parts of possible rust.
2) Check the clutch discs A for wear and replace if required.
3) Assemble and mount the clutch again. Tighten the bolts B with normal torque as
the flange C ensures the correct compression of the springs D and thus the
correct torque setting.
WARNING: If the clutch is overloaded by slipping for some time, it will get
heated and thus be worn quickly.
Overheating will damage the friction plates. If the clutch is
blocked or partly put out of function in other ways, the factory
guarantee will be discontinued.

Fig. 6-6
Fig. 6-6 The upper rear feed roller, the smooth roller A, should be secured against formation
of rust on the surface. If the machine is not in use for more than one day, the whole
surface should be lubricated with some oil.
ELECTRIC MOTORS
If the machine is not in use for a longer period, and in the winter time, it is
recommended to pull the spindle on the electric motors in to avoid formation of rust.
When dismounting the control panel in the cabin it should be stored in a dry and
warm place.
The plugs on the cables of the machine must be placed under a guard or wrapped up
to protect against wind and weather. They can be treated with spray.

9. STORAGE (WINTER STORAGE)
9. STORAGE (WINTER STORAGE)
When the season is over, the preparation for winter storage should be made
immediately after. First, clean the machine thoroughly. Dust and dirt absorb moisture
and moisture increases the formation of rust.
CAUTION: Be careful when cleaning with a high pressure cleaner. Never
spray directly on the bearings and grease all grease points
carefully after cleaning so that possible water is pressed out of
the bearings.
IMPORTANT: Grease all grease points after cleaning the machine.
The following points are instructions how to prepare for winter storage.
• Check the machine for wear and other defects – note down the necessary parts
you will need before the next season and order the spare parts.
• Dismount the PTO drive shafts, lubricate the profile tubes and keep them in a
dry place.
• Spray the machine with a thin coat of rust-preventing oil. This is especially
important on the parts polished with use.
• Change the oil in the gearboxes.
• Store the machine in a ventilated engine house.
• Lay up the machine to unload the tyres.
