Introduction
This quick reference guide has been produced to aid operators with
familiarisation and settings of CLAAS combine harvesters’ cutterbars.
CLAAS cutterbars are designed for output and efficiency but this can only be
achieved with correct operation and maintenance of the machine.
This guide is not designed to replace the Operator’s Manual but merely as a
reference document. More in depth information is available in the Operator’s
Manual.
ALWAYS READ THE OPERATOR’S MANUAL BEFORE OPERATING YOUR COMBINE.
Down time costs output
To get the most from the machine, the wheels/tracks must be turning. In order to
keep downtime to a minimum, it’s vital that routine maintenance is not
neglected. As well as servicing the machine according to the operator’s manual, a
good check of the machine is essential.
It is false economy to put off the replacement of worn parts until they break. For
example, a cracked knife section will take 5 minutes to change before starting
work, but usually a minimum of 10 minutes output will be lost, once work has
begun.
Abbreviations
Throughout this guide the following abbreviations are used:
‘LHS’ and ‘RHS’ refer to the left hand side and right hand side of the machine
respectively, taken from the rear of the machine facing in the direction of travel.

Safety
Safety is of the utmost importance whilst you are operating and maintaining
your cutterbar. Make sure that all of the risks are assessed to reduce the
likelihood of an accident.
Make sure you are familiar with the controls and operation of the machine and
have read the operator’s manual.
The cutterbar has many moving parts. Guards are designed to keep you safe;
please ensure that all guards are kept in place and in good condition when
operating the machine.
When doing any maintenance work or making adjustments outside of the
machine, make sure that the engine is switched off and the battery isolator key is
removed or have the cutterbar situated on the trolley.
If you need to go underneath the cutterbar whilst it is on the machine to make
adjustments etc. make sure that the cutterbar lift cylinder lock is in place.
When operating the machine be aware of the presence of people, particularly in
farmyards, always get someone to help you when manoeuvring the cutterbar on
or off the machine.
For more in-depth safety information please consult your operator’s manual.
Other information is available on the HSE website: www.hse.gov.uk
Always read the Operator’s Manual before using any new machine.

Cutterbar
Adjustments
The cutterbar is one of the most
important parts of the combine. It is
designed to cut and gather the crop from
the field. It then needs to feed the
material evenly, and preferably head first,
to the drum.
Dividers
The first part of the cutterbar to make contact with the crop are the dividers. There are
two types: the long divider or short divider.
Make sure that the height of the divider is set so it does not run on the ground. It is
recommended that the shoe (base of the divider) should be set to the same height as
the stubble.
Lifters
It is recommended that lifters should be fitted
to CLAAS cutterbars. The lifters should be
fitted by placing the first one on the fifth
finger from the RHS of the cutterbar, and then
on every fourth finger thereafter.
Lifters should be checked for wear/fatigue on
a daily basis and replaced if necessary. There
are two types of lifter available: the standard
lifter and the low cut lifter (for when lower
cutting heights are required e.g. peas).
4
Knife
Check that the knife is in good condition in order for it to work effectively. This involves
replacing damaged or broken sections, removing vertical movement by adjusting the
keeps, and making sure that the fingers are not rounded or bent. Regular
checks/adjustments will aid cleaner cutting and reduced stress on the knife drive
system.
Table Auger
The table auger is important for the
transportation of material to the
front elevator.
The timing of the retractable fingers
can be adjusted for different crops by
opening up the guard on the RHS of
the V770 & V930 and adjusting the
lever with a spanner. Use the top
holes for short crops and the lower
holes for tall crops. The 3rd hole from
bottom is the standard setting.
1. Adjust the stripper plates behind
the auger; this is made easier on this
machine by being able to adjust it
from the back of the header rather
than behind the auger.
Crop Wrapping
If an issue occurs with crop wrapping around the table auger in difficult conditions
there are a number of procedures that can be carried out; try one thing at a time.

2. Remove the intermediate retractable fingers along the length of the auger leaving
just the middle ones.
3. Check the height of the auger within the trough of the cutterbar. There should be a
minimum gap of 20mm between the trough and the auger flights.
4. The speed of the auger can be slowed by the fitting of optional sprockets on the chain
drive shaft.
Cutterbar
Adjustments
Skids
The skids underneath the cutterbar
should be set to suit the local conditions
e.g. stones, loose soil. It is recommended
that they are lifted right up in abrasive
conditions.
With this new header we now have an
increased sized auger (660mm) which
aids in bringing in a even crop feed.
6
With the new one piece table, the cutterbar is
able to extend from its shortest point to longest
point in one movement without having to fit
extension plates.
However, when the side knife is fitted the
combine knows this via a sensor (1) and restricts
the movement from its maximum of 600mm to
450mm. This reduces the risk of the reel coming
into contact with the side knife.

The side knife is easily attached with
a simple twist lock turnbuckle.
Both the side knife and the divider use the
new fork locating and locking device (2).
Side Knife
Installations
Simply slide into the lock and ¼ turn
the handle to lock in place (1).
Once the side knife is fitted and locked, all that is required is for two drive pipes
to be connected to the valve block on the side of the cutterbar. Once these are
fitted and the side knife is correctly/securely locked, the sensor engages the
solenoid and allows oil to flow through; thus removing the need to link pipes or
disengage drives on previous headers.

There are no shafts or belts to change or fit with the new cutter bar as it fitted with a
one piece extending drive shaft (1).
Unlike on previous machines, no slip clutch is fitted to the auger (2). We now we have
a rattle type clutch on the drive shaft as the overload protection.
There is no traditional wobble box fitted, we now use a straight through drive (3) driven
from a rear mounted gearbox (4). The gearbox is oil filled and is required to be regularly
serviced as per the maintenance section of the operator’s manual; make sure to observe
the correct procedure for checking/changing the oil.

The new Cerio cutterbar has a fixed
length table like the previous C range of
CLAAS cutterbars. However, we now
have the ability to adjust the length of
the table manually.
With undoing only 10 bolts we are able
to extend and retract the table into 5
different positions. (tightening torque of
blolts is 50 nm)
1. 0mm
2. 50mm
3. 100mm
4. 150mm
5. 200mm
There are no extra shafts to be fitted,
unlike the old vario cutterbar. The shaft
extends and retracts fully across the full
movement of table.
VARIO ONLY
The new cutterbar has a park feature for
transport, this is marked by a sticker for
manual placement; however, this can be
done automatically. With only the engine
running and the multi coupler connected,
by pressing and holding the auto contour
button (1) the cutter bar will bring the
table, and reel, into parked position. Then
when you reconnect, press the pre-set
height button (2) and hold until 3 beeps
are heard, the cutterbar will then return to
its previously set auto settings.
