ROAD TRAFFIC
The vehicle operator must always have two wheel
chocks on the vehicle.
When driving on public roads with agricultural or
forestry equipment attached, the highway code of
the respective country must be strictly complied
with.
Above all, no bale must be in the round baler.
If parts of the baler, the conditions of which are
clearly specified, are later changed or modified in
such a way that their operation will endanger any
other participants in traffic, the type approval will
become invalid and a new type approval must be
applied for. In this case the Iof working equipment
must be presented to the responsible technical
inspection authority for motor vehicles (e.g. TÜV) for
issuing an expertise (§ 19 para. 2 StVZO).
If you are in doubt that this may be the case, please
contact us as the manufacturer.
If the round baler is pulled after a tractor, especially
the following devices have to be connected:
- The cable of the lighting equipment.
- The cable for power supply.
Before starting to drive the condition of:
- the connection between pulling vehicle and baler
- the lighting equipment must be checked.
If the license plate given to the vehicle owner for
one his tractors is concealed when the baler is
hitched up, attach a picture of this plate, including its
lighting, onto the baler.
The local road traffic regulations may differ in
individual countries.
The maximum speed under the road traffic
regulations for the country of operation must be
observed. However, the hitched baler is designed to
travel at a maximum speed of 25 km/h (16 mph). It
is not permissible to exceed that speed.

access areas immediately if any is spilled.
000 298 456 6 - BA VARIANT 260/280 - 260/280 RC 4.1.1
Safety precautions
• BE EXTRA CAREFUL to keep hands, feet and
loose clothing away from moving parts.
• READ THIS MANUAL and take note of ALL
safety precautions included herein.
Attention!
Do not remove, install or make repairs to a
tire on a rim. Take tire and rim to the
nearest available tire specialist, who have
experience and the safety tools. If the tire
is not correctly positioned on the rim, or
the tire pressure is too high then the tire
bead is liable to loosen on one side,
resulting in the pressured air to leak out at
high speed and with force. This can lead
to the risk of the tire flying off and causing
serious injury!
Attention!
To provide more secure hand and foot
mobility, preventing slipping and possible
injury, always face the machine when
mounting and dismounting.
Danger!
Never operate the engine in a closed
building. Proper ventilation is required
under all circumstances.
Contact with belts, chains etc. can cause
injury. Keep clear.
A tire can explode during inflation and
cause serious injury or death. Never
increase air pressure beyond 35 PSI to
seat the bead on the rim. Replace a tire if
it has a defect. Replace a wheel rim which
has cracks, wear or severe rust. Make
sure that all the air is removed from a tire
before removing the tire from the rim.
Never use force on an inflated or partially
inflated tire. Make sure the tire is correctly
seated before inflating.
Danger!
Check the machine for leaks or any parts
that are broken, not working correctly, or
missing. Before you start the machine,
tighten all caps, dipsticks, battery covers,
etc.
Never use gasoline, naphtha or any other
volatile material for any cleaning
purposes. These materials may be toxic
and/or flammable.
Attention!
To help prevent personal injuries during
operation and maintenance, loose shirts,
sleeves or jackets must never be worn by
the operator.
Danger!
Before starting the tractor, be sure all
operating controls are in neutral. This will
ease starting loads on the starter and
batteries of the tractor and will eliminate
the accidental start up of power driven
equipment.
Travel speed should be such that
complete control and machine stability is
maintained at all times. Where possible,
avoid operating near ditches,
embankments and holes. Reduce speed
when turning, crossing slopes, and on
rough, slick, or muddy surfaces.
Use only metric tools. Other tools may not
fit properly. They may slip and cause
injury.
Danger!
Before leaving the tractor, stop the engine,
and remove the starter key. The gear shift
lever must be in neutral and the parking
brake engaged.
4.1.2 BA VARIANT 260/280 - 260/280 RC - 000 298 456 6
Danger!
On highways use lighting equipment
according to local laws. Keep SMV
emblem clean and visible. Replace SMV
emblem when damaged or sun faded.
Stop, look and listen before entering
public thoroughfare or a highway.
Attention!
Safety precautions
Safety signs
Collision of high speed road traffic and
slow moving machines can cause
personal injury or death.
Stay off slopes too steep for safe
operation. Shift down before you start up
or down a hill with heavy load. Avoid ”free
wheeling”.
Danger!
Provide a first aid kit for use in case of
accident.
As a safety precaution, it is suggested one or
more fire extinguishers be carried on the Baler
at all times. Fire extinguishers must be
purchased from Fire & Safety equipment supply
store.

Transporting baler on a public thoroughfare
Whenever a Baler is to be transported on a public
thoroughfare, the following preparation of the Baler
should be made:
• Position pickup in the transport position. Close
gate, raise pickup and converging wheels, if
equipped.
• Make sure warning devices, such as slow
moving vehicle emblem, reflectors, etc., are
installed, clean and are in good condition.
Replacement Parts:
– When replacement parts are necessary for
periodic maintenance and servicing, genuine
CLAAS replacements must be used to restore
your equipment to original specifications.
– CLAAS will not claim responsibility for usage of
unapproved parts and/or accessories and
damages as a result of their usage.
• Use flashinglights according to local laws. Keep
SMV emblem clean and visible. Replace SMV
emblem when damaged or sun faded.
• For reference purposes, measure the overall
width and height of the Baler. These
measurements are particularly important for
transporting along narrow roads and where
underpasses may be encountered.
• If the Baler hydraulic system is equipped with
an accumulator, make sure the accumulator
shutoff valve is closed.
000 298 456 6 - BA VARIANT 260/280 - 260/280 RC 4.1.3
Safety precautions
Danger!
Proper tire pressure should be maintained
at all times to insure stability during road
travel.
Always use a safety chain while
transporting baler. Sudden jolts or rocking
could cause the drawbar to break. If a
rocking motion occurs when transporting,
reduce speed until rocking stops. Check
rear tractor wheels for any tire tread wear
or pressure loss. Refer to operator’s
manual for tractor tire pressures.
Use care when towing baler at transport
speeds. Reduce speed if the weight of
baler exceeds weight of tractor.
When towing baler on public roads, an
extended mirror to improve visibility of
traffic behind the baler is recommended.
Mirrors are available from your dealer.
When the Baler is being transported on a public
thouroughfare, the following precautions must be
observed:
• Reduce speed before applying the brakes.
Using a hydrostatic transmission to slow the
vehicle is more effective than merely applying
the brakes.
If in doubt regarding local or state/provincial laws
pertaining to transportation of farm equipment,
consult your local law enforcement agency.
Danger!
Use or warning lights and turn signals are
recommended when transporting this
equipment on public roads, unless
prohibited by state or Local Laws.
A safety lighting kit is available from your
CLAAS dealer.
☞ Always use a safety chain when
transporting baler on public roads.
Transporting baler at speeds in excess
of 20 mph (32 km/h) is not
recommended.
Use care when towing baler at transport
speeds. Reduce speed if the combined
weight of baler with bale exceeds weight
of tractor. The approved minimal total
weight of tractor must not receed 2.5 tons
(2500 kg).
The towed baler can be transported
without brakesystem, when the approved
minimal total weight of tractor is 2.5 tons
(2500 kg).
Note!
Install new safety signs if the old are
destroyed, lost, painted over or can not be

TRANSPORTING BALER ON A PUBLIC THOROUGHFARE
Attention!
When transporting the baler on a highway
use SMV emblem (PN 514 155.1).
Recommended warning lights
1
Attention!
Use of flashing warning lights and turn
signals are recommended when towing this
equipment on public roadfs unless prohibited
by state or local regulations. An implement
safety lighting kit is available from your
Dealer.

Preparing for transport
Attention!
Always use a safety chain while transporting
baler. Sudden jolts or rocking could cause
the drawbar to break. If a rocking motion
occurs when transporting, reduce speed until
rocking stops. Check rear tractor wheels for
any tire tread wear or air pressure loss.
Refer to operator’s manual for tractor tire
pressures.
2
Note!
Route safety chain from baler through hitch and
secure to drawbar supporting structure as
shown. Remove all slack except what is needed
for turns. Do not make sharp turns when
transporting baler. Damage could result if
tongue strikes tractor tire.
000 298 456 6 - BA VARIANT 260/280 - 260/280 RC 4.1.5
Safety precautions
Danger!
Do not secure baler safety chain to drawbar.
Use care when towing baler at transport
speeds. Reduce speed if the combined
weight of baler with bale exceeds weight of
tractor. The approved minimal total weight of
tractor must not receed 6 tons (6000 kg).
The towed baler can be transported without
brakesystem, when the approved minimal
total weight of tractor is 6 tons (6000 kg).

Design and working principle
Design and working princip le
Power train
The machine is driven via a wide angle propshaft with
power take-off speeds of 540 rpm or 1000 rpm*.
The propshaft is fitted with a wide angle coupling on
tractor side and of and a freewheeling coupling, an
overload coupling* or a clutch* on baler side.
* Optional equipment
Shear coupling and freewheeling propshaft
With the round baler working under overload or in case
of blockage the shear pin on shear coupling (K) is
sheared off. This interrupts the power input.
(Fig. 3)
3
Cam clutch – propshaft
With the round baler working under overload or in case
of blockage of the rotor, the cam clutch (N) will
disengage the power input.
(Fig. 4)

Design and working principle
Pick up
Pick-up drum (T) picks stalks up neatly. Hold down (N)
or baffle plate (P) (OPTION) ensure even intake.
Danger!
Hold down (M) and tube (S) also serve as
safety installations and must never be
removed during operation.
The pickup height can be adjusted in 6 positions by
5
adjusting the depth stops (VARIANT 280 to serial-no.
73000904) or by hooking chains (D) to the respective
position (VARIANT 260 and VARIANT 280 from
serial-no. 73000905).
(Fig. 5, 6)
Hold down (N) above the pick-up supports the
transport of stalks and ensures uniform feeding of the
baling chamber, even when picking up non-uniform
swaths. The hold down can be removed after opening
locks (G).
Baffle plate (P) prevents coiling of short stalks, thin
swaths and aftermath.
The laterally mounted conveyor screw (B) conveyes
the stalks collected by the pick-up drum to the center,
where they are picked up by the rotor, i.e. quick
removal from the pick-up.

Cutter
(VARIANT 260/280 RC)
The cutter can be swivelled in and out by hydraulic
cylinders (Z) operated via push buttons in the control
box.
Cutter (A) cuts the material to be compressed to a
length of approx. 70 cm (27.5’’) before it enters into the
baling chamber.
Cutting rotor (R) is part of the cutter.
The cutter is equipped with 14 individual blades, which
7
are protected against foreign matter.
When picking up heavy foreign objects like stones,
hard wood or similar, springs (F) enable resilient
retraction of the blades.
After escaping the foreign particle the springs return
the blades to their original positions.
(Fig. 7, 8)
8
Dummy blade holder (optional)
Disassembled blades and dummy blades must be
stored in holder (H) provided for this purpose. Holder
(H) must be installed on the right-hand machine side at
the back of the platform.

Design and working principle
Baling chamber
The conveyor and cutter rotor feeds the picked up
stalks into the baling chamber and, in cooperation with
the belts, causes immediate rotation of the bale core.
The bale diameter can be adjusted from 0.90 m
(35.4’’) to max. 1.55 m (61.0’’) on VARIANT 260 and
0.90 m (35.4’’) to max. 1.70 m (66.9’’) on
VARIANT 280.
The baling pressure is adjustable and can be read on
the pressure gage.
Wrappi ng of ba les
Automatic wrapping is activated after the bale has
reached the specified diameter.
Automatic wrapping can be overridden manually on
the control box.

Active hydraulic system
Machines, year of construction 2005
The round balers Claas Variant 260 and 280 are
equipped with an „active hydraulic system“. The
function „active hydraulic system“ has two effects on
the machine.
– It affects the tension of the belts when closing the
tailgate: belts are tensioned.
– It affects a better belt guidance at the beginning of
the baling process in extreme cases of silage and
when dealing with small swaths. To ensure proper
operation, the bales must be pressed without a
soft core in such circumstances.

CHECK AND PAY ATTENTION TO THE FOLLOWING BEFORE STARTING OPERATION OF THE MACHINE
1. Remove or unpack all parts fastened with wire
and/or packed with the machine.
2. On the ROTO CUT version withdraw dummy
blades and dummy blade holder from the twine
box. Install dummy blade holder on the platform.
3. To open the tailgate the tractor must be fitted with
a control valve.
4. An additional single-acting control valve with rapid
action couplers must be installed to be able to
swing the blades in and out (VARIANT 260/
280 RC).
5. Check all connections for leaks.
6. Power take-off speed must be 540 rpm or
1000 rpm.
7. Couple the tractor power take-off shaft only at idle
speed.
8. On balers with swinging drawbar (observe
version). Check presence and fit of bushing in
trailer coupling ring.
9. Hitch the round baler to the trailer coupling ring of
the tractor.
Only hitch up balers with type-approved draw
bar.
10. Move the support to transport position.
15. Connect the 7-pin plug for travel light to tractor
socket and round baler.
16. Connect the control box cable to the 13-pin socket
on the round baler.
17. Mount the control box to the tractor within the
reach of the driver.
18. Close the tailgate before using the baler.
19. Work with a low power take-off shaft speed may
be required to avoid crumbling losses when
working with very dry and brittle baling material.
Work with thin swaths it may require a higher
travel speed.
20. Avoid travels at idle speed with the power take-off
shaft engaged.
21. Do not allow the round baler to run unnecessarily
with empty or open baling chamber. This may
cause damage to running belts.
22. Round baler with net wrapping facility:
For commissioning remove the blade guard and
coat the rubber rollers slightly with talcum powder.
23. Check wheel nuts or wheel studs for tight fit
(tightening torques see »Tec hn ica l Da t a«). Check
tire pressure, if necessary correct it as specified in
the »Technical Data«.
24. When assembling wheels retighten the wheel
bolts after the first 10 operating hours, then check
for tightness every 50 operating hours. Tightening
torques see »Specifications«.
11. Secure the propshaft guard with chains against
moving.
12. After hitching up the round baler and coupling the
propshaft make sure the propshaft is free to move
by cautiously driving right and left hand turns.
13. The best initial position of the pick-up drum is at a
distance of 20 to 30 mm (0.79’’ - 1.2’’) between
teeth and ground. The gage wheels on the pick-up
should be slightly raised when working on hard
stubbles, in order to avoid damage to the wheels.
14. Connect the 2-pin plug to the socket on the tractor
for electric power supply to the round baler.
If the tractor is not already equipped with a 2-pin
socket, such a socket should be retrofitted.
The cable with the 25 A pendant fuse, available
under part number 011 708.0, must be connected
directly to the positive and negative pole of the
tractor battery.
If the tractor has a 24V starting system this cable
must only be connected to the battery linked to
frame ground. Fuses with rating > 25 A are not
permitted.
Assembly of wheels is only permitted when using
lifting gear of appropriate load bearing capacity for
the total weight of the respective round baler type.
25. Check tension and condition of chains.
26. Check oil level in angular drives.
27. Check oil level in chain lubrication tank.
28. Never let the roundbaler run without supervision.

CUTTING DEVICE
(VARIANT 260/280 RC)
Dummy knives
When baling with removed knives (M), these knives
must be replaced by dummy knives (B) so that no
baling material is pressed through the knife slots.
Under harvesting conditions with a lot of stones we
recommend to replace half of the knives by dummy
knives.
Insert dummy knife (B) or knife into the dummy knife
holder.
If the cutting blades are not required for a longer
period of time, they should be replaced by dummy
1
blades to avoid unnecessary wear of cutting edges.
Note!
up to serial-no. 73000055
from serial-no. 73000056
If the dummy knife holder is not installed yet,
see page 8.6.3.
(Fig.1,2,3)
Installing and removing knives
Danger!
There is always a risk of injury when working
on the cutting facility.
Wear gloves.
To replace the knives proceed as follows:
– Swash the knives out (see chapter “operation”).
2
– To remove the knives disassemble the hold-down
from the front.
– For disassembly of the knives raise the pick-up
from the rear to highest position.

PRESSING BALES
Baling pressure adjustment
The baling density depends on the stalks and the
baling pressure.
The Variant 260/280 / 260/280 ROTO CUT is
equipped with a pressure regulator (E), which controls
the baling pressure from »0to5«.
1 = low baling pressure
5 = high baling pressure
1
Note!
For initial start-up of the baler the baling
pressure should be adjusted to position »2-3«
only. After 20 - 30 bales the baling pressure may
be increased.
The figures »0-5« on the pressure regulator (E) are
reference values.
For adjustment pull the locking plate (R) slightly
forward, adjust it accordingly and let it click into place.
(Fig. 1, 2)

Adjusting the bale diameter
The bale diameter can be adjusted by displacing
pointer (Z).
For this purpose loosen hand wheel (A) and set pointer
(Z) to the desired bale diameter on the scale.
The bale diameter can be adjusted from 0.90 m
(35.4’’) to max. 1.55 m (61.0’’) on VARIANT 260 and
from 0.90 m (35.4’’) to max. 1.70 m (66.9’’) on
VARIANT 280.
After completing the adjustment retighten hand wheel
(A).

Setting up the baler
Adjusting the soft core diameter
With the soft core facility the baling pressure inside the
baling chamber can be delayed depending on the
position of the pointer (X) (loosen hand wheel (B) to
adjust the pointer).
Example:
On the scale pointer (X) is in position »1.2« (soft core
diameter 1.2 m (47.2’’)).
The increase in baling pressure up to the soft core
diameter of 1.2 m (47.2’’) is accomplished with a
hydraulic pressure of approx. 20 bar only.
4
Once the soft core diameter of 1.2 m (47.2’’) is
reached the baling pressure is increased up to the
adjusted pressure level.
There is always a minimum difference of 0.3 m (11.8’’)
between the adjusted bale diameter and the soft core.
Example:
The desired bale diameter has been set to 1.2 m
(47.2’’).
The soft core can be set to max. 0.9 m (35.4’’).
Attention!
With the soft core facility, the function „active
hydraulic system“ is deactivated at the
beginning of the baling process. However,
the function „active hydraulic system“ is
activated again when closing the tailgate.
