The conveyor feed rakes (4) fill the conveyor channel.
The crop is pre-compressed by the action of the rakes.
Der Fülldruck im Förderkanal wird von Tastreche (16)
abgetastet. Bei Erreichen eines bestimmten Druckes
wird der Tastrechen zurückgeschwenkt und a feeder
rake transports the crop further into the bale channel.
The baling ram thrust is controlled automatically by the
hydraulic cylinder (9) at the bale channel flaps. When the
set pack length has been reached, the knotter mechanism star wheel projecting into the bale channel is
actuated. The Big Pack 88 is equipped with 4 knotters
(7) and the Big Pack 127 and 128 with 6 knotters (7).
The packs are deposited by a two-part pack chute (10).
In the bale channel the pre-compressed crop is pressed
to a highly compressed big pack by the baling ram (6).
The length and of course the density of the pack are
infinitely variable.
Big packs can therefore be produced for the most varied
of requirements.
Special Equipment
Swath distributor:
A swath distributor is available as an extra to ensure an
even feed of the bale channel with narrow swathers.
Hydraulic folding bale chute with rollers:
Especially when using the big baler for baling grass
silage, the rollers in the bale chute make it easier to
deposit the bales.
Compressor:
If hydraulic brakes are used on the big baler, a
compressor can be installed as an extra for knotting
device cleaning.
MultiCut:
The MultiCut cutting system is available particularly for
silage recovery or when short bailing material is needed.
A size reduction to as little as 45 mm is possible using
this.
Wide pick-up:
To better deal with wide harvester-thresher swaths, the
big baler can optionally be delivered with a wide pick-up
(2.4 m).
Anhängung Exportvarianten:
Je nach landesspezifischen Anforderungen stehen eine
drehbare Zugöse oder eine Hitch-Anhängung zur Verfügung.
Double knotter
Bei der Bergung von Silage hat der Doppelknoter gegenüber dem Einfachknoter einige Vorteile. Das Garn liegt
während des Pressens nicht im Knoter. Dadurch bleiben
sowohl Knoter als auch Garn während des Pressens
verschleißfrei. Die Bindeeinrichtung mit Doppelknoter ist
allerdings aufwendiger im Aufbau und in der Wartung/
Einstellung.
The BIG PACK Baler must be driven by a tractor with at
least a 65 kW (85 bhp) power output.
The BIG PACK Baler is hitched to the trailer coupling or
the swinging drawbar.
The swinging drawbar is fitted with a height adjustment
feature so that the big pack baler can operate in a
horizontal position.
The drive to the BIG PACK is via a PTO shaft which
transmits the torque from the tractor via a flywheel mass
(11) to a straight bevel gear pair (12). The maximum
input speed of 1000 rpm may not be exceeded, as there
is a risk of the machine being damaged.
The PTO shaft is equipped with a wide angle joint on the
tractor side. The operating instructions for the PTO shaft
are located at the PTO shaft. Before putting the big pack
baler into operation, the operating instructions for the
PTO shaft should also be read. These detail in particular
the shortening of the PTO shaft as well as any repair
and maintenance work.
The 2 m (2,4 m) wide pick up (2) collects the crop
cleanly.
A height-adjustable baffle plate (1) ensures error-free
collection and helps prevent blockages. The baling
material is carried via 2 filling augers (3), which are on
the left and right side of the pick-up, to the rake drum
(13) or the cutting rotor (14) and blades (15).
The pick up can be raised and lowered with the tractor
hydraulics. The feeler wheels on the pick up are heightadjustable so that the optimum pick up collection height
is always reached.

III - 1
Preparing the Big Pack Baler
Before starting adjustment work, place the big baler on the parking leg and uncouple
the tractor.
The drawbar can be set for either top or bottom
attachment. The tractor attachment height can be
adjusted in both the “top attachment” and the “bottom
attachment” positions (three-point linkage or pending
attachment).
The big baler must be attached horizontally to ensure
an optimum working method. The top of the twine box
is used as a match edge here.
3. Preparing the Big Pack Baler
3.1 Special Notes on Safety
• Particular care is required when attaching the big pack baler to or detaching it from the
tractor. There must be nobody between the tractor and the big pack baler. After coupling,
switch off the engine and remove the ignition key. Apply the flywheel brake.
• When carrying out care, maintenance, adjustment and repair work, always switch off the
PTO shaft, switch off the engine and remove the ignition key.
• Only put the big pack baler into operation when all protective devices have been attached
and are in the correct positions.
• The big pack baler may be operated with a maximum PTO shaft speed of 1000 rpm.
• Only PTO shafts specified by the manufacturer with the correct overload coupling and free
wheel facility may be used.
• The PTO shaft may only be attached and detached when the tractor PTO shaft is switched
off, the engine is switched off and the ignition key is removed.
• Lay hoses and connection cables in such a way that they are not under tension and do not
come into contact with the tractor wheels when going round corners.
• Check hydraulic hose lines regularly and replace if damaged or aged.
• When connecting hydraulic hoses to and disconnecting them from the tractor hydraulics
make sure that the hydraulics both in the tractor and in the machine are not pressurised.
3.2 Adjusting the Height of the Swinging Drawbar
• Secure the big pack baler from rolling away by using wheel chocks and putting on the
parking brake.
• Use suitable parking stands to support the big pack baler.
• Risk of crushing feet when winding down the jack stands.

3.3 Adapting the Main PTO Shaft
• Before sliding the PTO shaft on to that on the tractor, switch off the tractor PTO shaft,
switch off the engine and remove the ignition key. Apply the flywheel brake.
• Secure the big pack baler and the tractor from unintentional rolling away.
• Nobody may be between the tractor and the big pack baler when carrying out the cornering
required for the adaption of the PTO shaft length.
To adapt the length of the PTO shaft attach the big
pack baler to the tractor. The shortest PTO shaft
position is reached when going round tight corners.
To measure, take the PTO shaft apart and slide each
half (1) and (2) on to the baler and the tractor
respectively. The exact procedure for the length
adaption can be found in the PTO shaft manufacturer's
operating instructions.

3.4 Putting the Big Pack Baler into Operation
3.4.1 General
Main Drive
A straight bevel gear pair provides the main drive. The
necessary torque is transmitted by the PTO shaft and a
large flywheel mass. The maximum PTO shaft speed of
1000 rpm may not be exceeded. The PTO shaft on the
machine is fitted with a slip clutch facility (1) as a safety
measure.
There is a cam-type cut-out clutch located
on the rear side of the flywheel mass. As
soon as the clutch engages, stop the
machine, turn off the PTO shaft immediately
und Schwungrad abbremsen. The camtype cut-out clutch switches on again
automatically once the fault has been
eliminated.
Feed Rake Drum Drive
The drive for the feed rake drum is located on the left
hand side of the machine. The gearbox is fitted with a
spring-loaded ratchet clutch as a safety measure.
As soon as the ratched clutch engages,
stop the machine, turn off the PTO shaft
immediately. The ratchet clutch starts
working again automatically once the
fault has been eliminated.
Knotter Shaft Drive
The drive for the knotter shaft is provided by an angular
gear arrangement. A PTO shaft transmits the torque to
the knotter shaft.

6.1 Special Notes on Safety
• The following always applies for all maintenance, mounting, repair and adjustment work:
switch off the PTO shaft. Switch off the engine and remove the ignition key. Apply the
flywheel brake.
• Only put the big pack baler into operation when all protective devices have been attached
and are in a proper operating condition.
• In dangerous situations stop the PTO shaft and bring the big pack baler to a standstill
immediately.
• Never run the big pack baler without an operator on the tractor.
• When working under the machine or on the needles in the baling channel, the needle carrier
must be secured against falling down. Danger of injury!
6.2 Adjusting the Needles
Carry out all adjustments to the needles without any twine threaded!
6.2.1 Lateral Adjustment of the Needles
Insert the needles (1) centrally between the clamping
brackets and the needle yoke, turn them towards the
needle slits and screw tight with screws (2). To be able
to carry out the adjustment, the binding process is
initiated manually and the needle yoke manually turned
up in the working direction at the flywheel mass. When
raised, the needles must just laterally touch the left and
right hand sides of the knotter frames. To correct the
lateral distance, the screws (2) are undone and the
needles laterally positioned with the adjusting screws
(3). Always make sure that the screws are all tightened
up firmly again after making the adjustment.

6.2.2 Height of the Needles on the Knotter
To set the height of the needles on entry into the knotter, the needle yoke is turned upwards at the flywheel
mass after manually initating the binding process. It is
turned up in the working direction until the rollers in the
needle tips are above the cleaning disc on the carrier (2).
The distance "a" from the lower edges of the needle rollers to the upper edge of the cleaning disk must be 1 to
3 mm. This setting can be corrected with screw (7) after
screw (6) has been undone. Always make sure that the
screws are all tightened up firmly again after making the
adjustment.
6.2.3 Needles' Upper Dead Centre
The needle yoke is set in motion by the needle drive
connecting rod (3) after the binding process has been
initiated. To be able to check the needles' dead centre,
turn the needle yoke up to its highest position (dead
centre). The needle drive connecting rod (3) and the
crank arm (1) should then be overlap each other. The
twine needles (4) project out of the knotter. The distance
"b" between the upper edge of the carrier disc (2) and
the midpoint of the roller in the needle tip must be at
least 85 mm. Should this setting be incorrect, it can be
corrected by shortening or lengthening the needle drive
connecting rod.

6.2.5 Needles Relative to the Baling Ram
To set the needles relative to the baling ram, the drive
PTO shaft for the knotter shaft must first of all be dismounted. The baling ram is turned manually in the working direction at the flywheel mass until the crank arms
and the piston rods are overlapping each other (i.e. the
baling ram is at the front dead centre).
The knotter gear is then turned until the coloured mar-
king on the knotter shaft crown wheel is aligned with
the upper rear edge of the knotter gearbox. After the
adjustment has been made place the PTO shaft for the
knotter shaft back in position and secure. Check the
settings as described in the following chapter.
Checking the Setting of the Needles Relative to the Baling Ram
To be able to check the setting of the needles relative to
the baling ram, the binding process is initiated. The baling ram (2) is manually turned in the working direction at
the flywheel mass until the tips (1) of the binding needles are at the same height as the ram blade. In this
position the needle tip must be covered by the baling
ram, with the dimension a = 40–70 mm. If this is not the
case the setting must be corrected by altering the
position of the knotter drive PTO shaft.

The adjustment is made by undoing the screws (3) and
(4) on the twine bar (1). Shift the twine bar in the slot
until the dimension "b" = 2–5 mm.
The setting for the distance at the side "a" is adjusted
at the control rod assembly (5) for the twine bar (1). To
make the adjustment undo self-locking nuts (6) and
take off the ball head (7). Twist the control rod until the
dimension a is set at a = 0 – 5 mm. Wenn der Garnriegel in Richtung Kanalschlitz gedrückt wird, muß das
Maß "a" noch eingehalten werden. Tighten up the selflocking nuts again.
If the twine bars (1) are in the middle of the openings,
the distance from the tip of the twine bar and the inner
side of the needle (2) must be "b" = 2–5 mm.
6.3.1 Adjusting the Twine Bar
Initiate the binding process manually (see chapter 5.4.4
"Initiating the Binding Process Manually"). Turn the
flywheel in the working direction. The needles move
upwards. At the same time move the twine bars over
the openings through which the needles transport the
twine to the knotter.
6.3 Twine Bar
The twine bar (1) draws the twine down from the needle
and presses it against the knotter hook. If the twine is
not taken by the twine bars, the knotter hook cannot
take up the twine.

6.5 Baling Ram Setting
The bale chamber is equipped with two blades (6).
• The baling ram (3) on the Big Pack 127/128 is
equipped with seven blades (5).
• The baling ram (3) on the Big Pack 88 on the other
hand is only fitted with five blades (5) due to the
smaller width of the bale chamber.
Adjusting the Baling Ram Blades
The baling ram blades must be set precisely to obtain a
smooth surface on the underside of the pack. To adjust
the distance to "a" = 2 mm the height of the baling ram
can be adjusted with the eccentric sleeves (2) on the
guide rollers. After separating the two halves of the
clamp bedding (1), the eccentric sleeves are turned to
raise and lower the baling ram. After making the adjustment, the tighten the two halves of the clamp bedding
again. Make sure that the guide rails (4) and the guide
rollers do not become dirty. This can lead to increased
wear and an imprecise height setting of the baling ram.
• The guide rollers for the baling ram must carry uniformly.
• The gap between the baling ram blade and the blades in the bale channel must be uniform
over the whole width of the ram.

6.8.2 Setting the damper equipment
The damper equipment prevents the anvil from switching
on the VFS-clutch through its own movements. The
adjustable tension of the pressure spring (20) depends
on e.g. the condition of the brake (wear grade, paint,
rust).
To check the spring's tension you have to actuate the
back holder rake (12). For that reason put some feeder
in the big baler. If the back holder rake swings back again
(at full number of revolution), the anvil (15) is allowed to
bounce back from the adjust screw (14) max. 1 - 3 mm.
If the anvil bounces back further you will have to increase
the tension of the pressure spring (20).
If the back holder rake swings out, the anvil has to arrive
at the adjust screw (11). If not, reduce the spring tension.
6.8.1 Lateral setting of the damper
equipment
To compensate tolerances because of welding and
adaptation the damper equipment is adjustable.
Checking the settings:
Press the anvil (15) against the adjust screw (14). In this
position there should be a gap of 6 - 8 mm to the front
from the strech screw for the pressure spring (20) in the
slot (22) of the anvil. To correct the adjustment undo the
screws (21) and correspondingly displace the damper
equipment.

6.10 Adjusting the Flywheel Cleaning Mechanism
(only Big Pack 88)
Even small deposits of dirt in the interior of the flywheel
(1) can lead to imbalances. The setting of the plastic
bar (2) should therefore be checked regularly. If the gap
between the flywheel and the plastic bar is too large,
undo the nuts (5) on the bracket (4) and slide the plastic
bar in the slots up towards the flywheel mass. Tighten
up the nuts again.

The spring (23) is responsible for bringing the back
holder rake into its swing position again after the feeder
insertion (over the anvil (15) and the threaded rod (13)).
The anvil (15) therefore has to arrive at the adjust screw
(24).
The arrange measure is swing length “C” = 140 mm.
• The tension of the swing should be increased, if
- the end position of the back holder rake and the
anvil cannot be reached (see chapter 6.8.)
- the filling of the press channel's height is not
sufficient.
-> Badly filled baler corners mostly result due to
bad forms of swathe or onesided driving
conditions
• A too high tension of the spring may lead to
overload and finally to a blockade of the rake.

6.13 Basic adjustment of the flywheel
brake
The flywheel brake must be re-adjusted if the brake
power is no longer satisfactory (worn brake block) or if
the flywheel brake has been removed (e.g. after
replacement of the friction clutch).
For this proceed as follows:
1. Remove pin (1) from the brake lever and remove the
brake lever (this step is best with the flywheel brake
pulled).
2. Release bolts (2) and remove the protective cover.
3. Install the brake lever.
4. Release the brake.
5. Check dimension „A“: this should be equal to 200
mm. Adjust as necessary using nut (3).
6. Pull the brake.
7. Check dimension „B“: this should be equal to 28
mm. To correct dimension „B“ release the brake
again and adjust the grub screws (4) at either side of
the brake saddle. This will move the brake blocks
closer to the brake disc. Pull the brake again and
check dimension „B“.
The distance between brake saddle (5)
and rods (6) must be equal at either side
of the brake saddle. Correct by adjusting
the bolts (4) as required.

cone on the auger shaft must be loosened. To do this
the hexagonal nut (4) is loosened to the point where
one of its faces projects approx. 1 mm over the end of
the shaft. The auger comes loose when tapped lightly
against the hexagonal nut (4). The optimum position
can be found by making a corresponding rotation. The
auger can only be turned when there is no twine in the
twine mount. The clamping strength is adjusted at the
hexagonal nut (3) which tensions the helical spring (2)
on the twine mount. The twine mount should clamp the
twine just tightly enough for it not to be pulled out of the
twine mount during the tying process. If the clamping
action is too strong the twine is frayed. The clamping
strength should be set proportionally to the increasing
pack density. The type and moisture content of the crop
as well as the choice of twine require different settings,
which can be tried out under working conditions if
necessary. The spring (2) must never be tensioned to
the length of the block.

10.1 Special Notes on Safety
• Repair, care, maintenance and cleaning work may only be carried out with the machine at a
standstill. Switch off the engine and remove the ignition key. Apply the flywheel brake.
• Secure the big pack baler and the tractor from rolling away.
• After completing care and maintenance work, replace all protective plates and protective
devices again properly.
• Avoid skin contact with oils, greases, cleaning agents and solvents.
• In case of injuries or burns caused by oils, cleaning agents or solvents, seek immediate
medical attention.
• Follow all other notes on safety to prevent injuries and accidents.
10.2 General
Before putting the big pack baler away for the winter, clean inside and outside thoroughly. If using a high-pressure
cleaner, do not direct the water jet at the bearings. Lubricate all lubrication points after cleaning. Do not wipe away
any grease coming out of the bearings. The grease ring provides additional protection against moisture.
Remove drive chains and chains for the chain coupling (then check rake setting) and wash in petroleum (do not
use any other solvent). At the same time check for wear on the chains and chain wheels. Oil the chains once
cleaned and then mount and tighten up again.
Check that all moving parts such as deflection rollers, joints, tensioning rollers etc. can be moved easily. If
necessary dismount, clean, grease and remount. Replace with new parts if required. Only use genuine KRONE
replacement parts.
Take the PTO shafts apart. Lubricate the inner tubes and the guard tubes. Grease the lubricating nipple on the
universal joint as well as the bearing rings on the guard tubes.
Park the big pack baler in a dry place away from artificial fertilisers and animal stalls.
Touch up the paintwork where required. Protect bare spots, especially the twine lugs, the knotter (knotter clamp
and the twine retaining disk) and the bale channel thoroughly with plant-based oils.
Only jack up the big pack baler with a suitable vehicle jack. Make sure that the machine is in a
stable position when jacked up.
Jack up the round baler to prevent damage to the tyres (damage to the tyres can occur when the round baler
stands in the same position for a long time). Protect the tyres from the effects of oil, direct sunshine etc.
Release the parking brake and the flywheel brake. Drain condensation from the compressed air reservoir tanks.
Have the necessary repair work carried out in the time directly after the harvest season. Prepare a list of all spare
parts required. By doing this it is easier for your KRONE dealer to process your orders and you can be sure that
your machine will be in top condition for the start of the next season.

12.1 MultiCut cutting system
The following always applies for all maintenance, assembly, repair and adjustment work:
• Bring the machine to a standstill.
• Switch off the engine and remove the ignition key.
• Secure the tractor and the Big Pack baler from rolling away.
• Secure the pick-up against intentional lowering.
• There is a high risk of injury when fitting and removing the blades. Only touch blades
with suitable gloves.
• Engage the flywheel brake.
12.1.1 Special notes on safety
12.1.2 General
The Big Pack MultiCut has a cutting system with a cutting
roller and fixed blades.
Cutting allows better bale processing and increased bale
density. The blades can be swung out of the conveyor
channel hydraulically from the tractor if there are blockages.
The machine can also be used without blades. The cutting
roller then takes over the conveying function between the
pick-up and pre-baling channel.
The Big Pack MultiCut 88 cutting system can be equipped
with a max. of 15 blades. The Big Pack MultiCut 128 and
Big Pack MultiCut 127 cutting system can be equipped
with a max. of 25 blades. Theoretically cutting length is 45
mm (Adjustment "45" on the selector disc). A cutting
length of "90 mm" can be achieved with two of the blade
sets. The cutting length can be read off the selector disc
(1).
The cutting length is determined by the number of
blades used:
• Big Pack MultiCut:

Switching blade control shaft off
hydraulically
The hydraulic cylinder is operated from the tractor. The
zero position is indicated on the comfort control.
The hydraulic blade stop is used,
amongst other things, to eliminate any
blockages.
After a prolonged operation of the
hydraulic zero blade setting it may
happen that the blades slowly return into
the channel (this can be caused by an oil
leakage of the tractor). It is therefore
recommended to switch off the blade
control shaft mechanically.
