GENERAL INFORMATION
1. Minimum tractor engine power used should be
51 kW / 70 hp for the FC 240 P and 60
kW / 80 hp for the FC 280 P. If tractor power is
insufficient, quality of work will be unsatisfactory.
2. - FC 240 P mower conditioner can be
adapted to all tractors having a PTO speed of
540 rpm and equipped with a normalized Cat.
2 three-point hitch.
- FC 280 P mower conditioner can be
adapted to all tractors having a PTO speed of
1000 rpm and equipped with a normalized
Cat. 2 three-point hitch.
3. FC 240 P and FC 280 P are equipped with
adjustable lower hitch pins allowing the machine to be offset +/- 50 mm (2") to the left and
to the right.
4. To adjust lower hitch pins (T) (photo A), loosen
the 4 hexagonal screws (U) of collar flanges (V)
on each side.
Reposition lower hitch pins respecting :
825 mm (28") dimension (page 23) and retighten
screws (U). Torque : 12 daNm / 88 ft.lbs.
Check tightness of screws (U) after the first
ten hours of use.
Note : 825 mm dimension is correct when the
distance (X) is the same for the two lower hitch pins
The parking stand on the FC 240 P and FC 280 P machines has been designed to support the
weight of the 3-point frame only and the following points must be respected :
1) If at any time it becomes necessary to move the machine with a fork lift or loader type
vehicle it is very important that the 3-point frame is :
a) lifted from the ground first, when lifting the machine
b) lowered onto the ground last when lowering the machine.
Failure to comply with the above points will result in damage being caused to the parking
stand / operating lever.
2) If at any time it becomes necessary to transport the machine on a lorry or trailer then some
form of support must be used i.e. a piece of wood, to take the weight of the 3-point frame,
so relieving the weight on the parking stand. This action will prevent damage being

positioning of hitch pins :
Follow fig. B for category 2 tractors with narrow wheel
tracks.
Follow fig. C for category 2 tractors with standard
wheel tracks.
Follow fig. D for category 2 tractors with wide wheel
tracks.
NOTE : Always attach machine in such a way that
distance (A) is approximately 50 mm (2").
- 24 -
B) Attaching the machine
- Attach the lower links (A) to the hitch pins and
secure with linchpins (photo E).
Select the attachment holes of the turn buckle
(P) on the tractor side and machine side (D) so
that it is approximately parallel with the tractor
lower draught arms (A) in working position and
in raised position (photo E).
- Connect hydraulic hose (H) to the tractors single
acting valve (photo E). First make sure that the
hydraulic connection is clean ; if not, cylinders may
not function correctly.
C) Adjusting cutting / conditioning unit
horizontal position
- Activate the tractors hydraulic lift mechanism and
check that the 3-point frame is lifted parallel to the
ground (photo F). If necessary, adjust levelling rods
(F) (photo E).
If, once this adjustment has been made, the cutting/
conditioning unit is still not parallel to the 3-point
frame, level it by adjusting threaded cylinder rod (V)
(photo F).
D) Raising cutting / conditioning unit
and parking stand
NOTE : ONLY OPERATE THE PARKING STAND
(L) WHEN THE CUTTING CONDITIONING
UNIT IS IN THE VERTICAL TRANSPORT
POSITION (COMPENSATING SPRING
IS RELEASED).
- Activate the machines hydraulic cylinders to bring
the cutting/conditioning unit into its vertical position.
- With the machine in the transport position (cutterbar vertical), raise the stand (E) and connect it to the
suspension rod (F) using pin (L) (photo G).
(
Note : The PTO shaft must be adapted
at a later stage. Correct length cannot be checked as long as the cutting / conditioning unit is in horizontal position.
- 25 -
P.T.O. SHAFT
THE LENGTH OF THE PTO SHAFT MUST BE ADAPTED TO THE TRACTOR BEING USED WITH
THE CUTTERBAR LATCHED IN VERTICAL TRANSPORT POSITION (PRESSURE IN CUTTERBAR
LIFT CYLINDER RELEASED).
Proceed as follows to check that the PTO shaft length is correct when coupling the machine to a tractor for the
first time and when using another tractor.
1° Remove the PTO shaft and separate the two half transmission tubes.
2° Raise the cutting / conditioning unit to its full vertical transport position, then release hydraulic pressure
to engage latch (I) (photo 21).
3° Set the tractor 3-point lift to the position where the distance between tractor and machine PTO stub is as short
as possible.
4° Connect the half transmission tubes to their corresponding PTO stubs (free wheel clutch on machine side,
tractor end yoke on the 540 rpm PTO for FC 240 P and on the 1000 rpm PTO for FC 280 P). Hold both
shaft halves next to one another. The outer guard tube should remain clear of the protection cone by "a" =
40 mm (1 1/2") (see photo H). If this is not the case, shorten the two transmission tubes and the two guard tubes
by the same length (photos I and J). Deburr, bevel and clean the tubes (photo K). Grease the inside of the outer
tube (photo I).
5° Lower the cutting / conditioning unit to its horizontal working position and check that the overlap is
at least 150 mm (6") by keeping both shaft halves next to one another. Reassemble the PTO sliding tubes and
connect the PTO shaft in place while the cutterbar is in its horizontal position.
- 26 -
These recommendations and adjustments must be respected to avoid damage or
premature wear of the PTO. Repeat these checks when the machine is fitted to any other
tractor.
Only attach the FC 240 P to the 540 rpm PTO and the FC 280 P to the 1000 rpm PTO.
To avoid accidents which could be serious, make sure that the guards are always correctly
in place and secured with the safety chains (C). On the machine side the chain should be
fixed onto the oscillating arm grommet (photo N). Replace the guards immediately as soon
as they have been damaged.
TRANSPORT
WARNING : WAIT UNTIL DISCS AND ROTOR COME TO A COMPLETE STOP BEFORE
RAISING THE CUTTING CONDITIONING UNIT INTO THE VERTICAL POSITION.
BE SURE THAT EVERYONE IS AT A SAFE DISTANCE FROM THE MOWER CONDITIONER
PIVOTING AREA.
WARNING : BEFORE TRANSPORTING THE MACHINE ON THE PUBLIC HIGHWAY, THE
OPERATOR SHOULD MAKE SURE THAT THE MACHINE CONFORMS TO THE HIGHWAY
CODE.
To transport the machine on public roads or from one field to another, proceed as follows :
- Make sure discs and rotor have come to a complete stop.
- Lift the machine using the tractor 3-point linkage
- Pressurize the hydraulic cylinders to lift the cutting conditioning unit into its vertical position.
- The cutting conditioning unit will lift and simultaneously pivot towards the rear.
- Once the cutterbar has reached the end of its trajectory, release hydraulic pressure and the cutterbar will be
automatically locked in place (photo 20).
Never operate the PTO shafts at too great an angle (X = 25° maximum) (fig. M).
- 27 -
WORKING POSITION AND ADJUSTMENTS
1) Pressurize hydraulic cylinders and pull cord (A) to
free lock (I) (photo 21).
2) Lower cutting conditioning unit into the work posi-
tion by releasing the hydraulic pressure. As soon
as the cutting conditioning unit starts to pivot,
release pressure on the cord (A).
When the cutting conditioning unit is in the horizontal position [cylinder (V) is fully extended], lower
machine with the hydraulic lift until the roll pin
(F) is exactly centered in its aperture (H) (photo
23).
- 28 -
Adjustment of chassis height from the
ground :
1. For tractors equipped with hydraulic position
control function : set lower link height so that roll
pin (F) is exactly centered in its aperture (H) (photo
23).
This gives height E = 400 mm approximately
(photo 22), which corresponds to a cutting height of
30 mm.
2. For tractors not equipped with hydraulic
position control function, the stop-chain (L) which
is delivered with the machine must be used.
Proceed as follows to install this chain (L) (photos
24 and 25) :
- Remove roll pin (K) from right hitch pin, attach
chain (L) and washer (M) and reinstall roll pin (K).
- Lower machine until hitch pins (T) are 400 mm
(16") or slightly more from the ground [roll pin (F)
is slightly excentered in regard to its aperture (H)].
- Attach stop-chain (L) with its hook (O) to the
uppermost free holes at the tractors top link
attachment clevis (photo 25).
- Lower the machine into working position. Chassis
height is correct when :
- The cutting conditioning unit is resting
on the ground
- Stop-chain (L) is tight.
- Roll pin (F) is exactly centered in its
aperture (H) (photo 23).
- To keep this adjustment permanently, close hook
eyelet (O) with roll pin.
WARNING : BEFORE LOWERING THE MACHINE IN WORK POSITION, ENSURE ALL
PERSONS ARE WELL CLEAR OF THE MOWER-CONDITIONER PIVOTING AREA.
- 29 -
INNER DEFLECTOR
Conditioning degree is governed by an inner deflector adjustable in 3 different positions (O) with lever (C). Each time
conditioning is readjusted do not forget to reinstall the two spring cotters (E) (photo 28 and figure 29).
- For maximum conditioning select the intermediate or lower position of deflector.
- For minimum conditioning when mowing leguminous crops, deflector can be adjusted in the highest position giving
the greatest distance between deflector and rotor fingers.
ADJUSTMENTS
BEFORE CARRYING OUT ANY OPERATION SUCH AS MAINTENANCE OR ADJUSTMENT ON
THE MACHINE, STOP THE TRACTOR ENGINE, REMOVE IGNITION KEY AND WAIT FOR
ROTATING DISCS AND ROTOR TO STOP.
Cutting height
Maximum cutting height (80 mm / 3") (fig. 26) is achieved when the discs are parallel to the ground. Adjustment of
cutting height is achieved by altering the cutterbar tilt angle. This is effected by varying top link length (P) (photo
25) until desired cutting height is achieved. To minimize blade and disc wear, improve grass regrowth and get
maximum nutritive value from the crop, minimum cutting height should never be adjusted less than 30 mm
/ 1 1/4" (fig. 27).
A raised skid shoe kit (set no. 107 6100) available as an optional equipment provides a cutting height adjustable
between 60 mm and 120 mm (2.5" and 5") (see page 45).
MAXIMUM CUTTING HEIGHT MINIMUM CUTTING HEIGHT

Swath screens
Desired swath width is obtained by adjusting swath screens (T) (figure 30). Swath screens are locked in position
by means of 2 handles (M) (figure 30).
Adjustment of compensating spring
tension
The compensating spring or system is factory adjusted
so that dimension (X) (photo 32) is:
- 25 mm (1") for the FC 240 P
- 55 mm (2 1/6") for the FC 280 P.
When working conditions are difficult, adjustment can
be modified as follows :
- Put machine in parking position, which releases
compensating springs (P) (photo 32).
- Loosen lock nut (H) and adjust rod (F).
- After adjustment retighten lock nut (H).
Maxi length of dimension (X) must not exceed :
- 115 mm / 4"1/2 for the FC 240 P
- 75 mm / 3" for the FC 280 P.
- 31 -
A breakaway latch allows the cutting conditioning unit
to swing back if an obstruction is hit (photo 33).
IF THE LATCH RELEASES, STOP THE TRACTOR
IMMEDIATELY AND DISENGAGE THE PTO.
To reset the cutterbar, back up the mower conditioner
until the cutterbar is in its normal position.
The factory setting of the latch is adapted to most
working conditions.
NOTE : Before using the mower conditioner, the breakaway linkage must be checked for good operation
making sure all components slide correctly and are
well greased. Check for any cutting conditioning unit
damage if an obstruction is encountered.
The stack (Y) of spring washers should be compressed to 95 mm ( 3 3/4") (fig. 35). Observe spring washer
arrangement in fig. 35 carefully.
If after resetting the cutterbar continues to break away, the pressure of spring assembly (A) (photo 34) can be
increased but stacking (Y) must never be less than 91 mm (3 2/3"), otherwise safety disengagement cannot function.

OPERATING THE MOWER CONDITIONER
GENERAL
Before engaging the machine into the grass, lower the cutting conditioning unit to the ground and bring the PTO shaft
up to its nominal speed (540 rpm for the FC 240 P and 1000 rpm for the FC 280 P).
Do not allow the PTO to drop to too low a speed as this would reduce cutting quality and cause rotor plugging. If
this should occur, immediately disconnect the PTO, stop the tractor engine and remove the ignition key. Clear crop
from the rotor and make sure fingers and belts are in good condition and the belts are well tensioned.
Forward speed should be determined in accordance with work conditions.
We recommend that forward speed be reduced when working in high density crops or in difficult conditions.
Check that covers (14-15) (photos 51 and 51 A, page 33) of inner and outer cones are securely attached. Replace
immediately if worn or damaged.
ROTOR SPEED
The mower conditioner is equipped with a 2 speed rotor : 888 and 615 rpm. These speeds are obtained by connecting
the PTO shaft to one of the two rotor drive shafts (photo 38).
FC 280 P (1000 rpm drive gearbox) (fig. 39, p. 34)
- High speed (upper drive shaft, fig. 39) is recom-
mended for conditioning gramineous crops.
- Low speed (lower drive shaft, fig. 39) is recom-
mended for conditioning leguminous crops.
FC 240 P (540 rpm drive gearbox) (fig. 40, p. 34)
- High speed (lower drive shaft, fig. 40) is recommended for conditioning gramineous crops.
- Low speed (upper drive shaft, fig. 40) is recommended for conditioning leguminous crops.
MAKE SURE THAT THE DRIVE
SHAFT NOT IN USE IS ALWAYS
COVERED BY GUARD (E) SUPPLIED
FOR THIS PURPOSE (PHOTO 38).
THE POSITIONING OF THE GUARD (E)
IS CARRIED OUT BY PIVOTING
DOWNWARDS OR UPWARDS
WITHOUT COMPLETELY REMOV-ING
THE WING NUT.
BEFORE STARTING WORK BRING THE GUARD DOWN INTO THE CORRECT POSITION.
FASTEN THE FRONT SAFETY CURTAIN TO THE LATERAL CURTAINS USING THE
STRAPS PROVIDED.
DO NOT STAND ON OR LEAN AGAINST THE GUARD.
BEFORE BEGINNING WORK, KEEP ALL PEOPLE AND ANIMALS AWAY FROM THE
DANGER ZONE OF THE MACHINE (RISK OF PROJECTION)

It is forbidden to discard oil, grease or filters of any type. These must be given to specialised
waste disposal organisations to protect the environment.
BEFORE CARRYING OUT ANY OPERATION SUCH AS MAINTENANCE OR ADJUSTMENT
ON THE MACHINE, STOP THE TRACTOR ENGINE, REMOVE IGNITION KEY AND WAIT
FOR ROTATING DISCS AND ROTOR TO STOP BEFORE LEAVING THE TRACTOR.
IMPORTANT !
After the first 10 hours of use imperatively change oil [SAE 80 W EP (GL4)] in : - cutterbar
- lateral gearbox
- rotor gearbox.
Thereafter, oil must be changed after every 200 hours of work and at least once per year.
CHANGING CUTTERBAR OIL
Before changing the oil of the cutterbar, let the machine run a few minutes so the oil gets hot.
Proceed as follows to change the cutterbar oil :
1° Lift the cutterbar into its vertical position by means of the hydraulic cylinders (photo 42).
2° Remove inner shoe (18) of main gearcase (photo 42).
3° Remove magnetic oil plug and its washer (19, 20) (photo 42 and fig. 43A) and let the old oil drain out into an
appropriate container.
4° Remove inner plug (21) (fig. 43).
5° Clean magnetic plug and its washer (19, 20) and fit
back into place.
6° Fit inner shoe (18) back into place.
7° Lower the cutterbar so that it is horizontal to the
ground and pour the quantity of fresh oil prescribed
below into the fill plug hole (21) (fig. 43).
8° Clean plugs (21) and their washers (22) and fit back
into place (fig. 43).
QUANTITY OF OIL IN CUTTERBAR
FC 240 P : 1,7 l / 3.4 US pint / 3 Imp pint
FC 280 P : 2,0 l / 4 US pint / 3.5 Imp pint
SAFETY CLUTCH WITH SHEAR BOLT
If during work the conditioning rotor stops rotating but
the discs are still driven, disengage the P.T.O., stop
the tractor engine, remove ignition key and wait for all
rotating parts to stop before leaving the tractor.
Remove the 2 broken parts of the shear bolt and
replace it by a new bolt (V) (part no. 800 608 50)
(specification H.M 8 x 50 grade 8.8) and self locking nut
(part no. 802 008 40). Insert the bolt in the direction
of arrow (F) as shown in the photo opposite. Fix
the secondary PTO shaft back in place after the
operation and attach the security chains.
- 36 -
CHECKING OIL IN THE CUTTERBAR (fig. 43 and 43 A)
Cutterbar oil level can be checked by measuring oil
level through both filler plugs (21) when the cutterbar is
perfectly horizontal lengthways and crosswise (X and
Y).
Use a spirit level to ascertain that this is the case.
Correct oil level is 6 to 7 mm (1/4") at both filler
plugs (21) (fig. 43).
If in doubt as to the amount of oil contained in the
cutterbar, do not add oil. Drain the oil completely and
refill with the prescribed quantity.
NOTE : Provided above instructions are strictly observed, there is no cause for alarm if it is found that the
transmission case is very hot to touch, provided that the discs turn freely by hand.
Attention : Make sure that the tractor engine is shut off, ignition key removed and PTO shaft
disconnected before carrying out this operation.
- 37 -
CHANGING GEARBOX OIL
Check gearbox oil level daily. Top up with SAE 80 W
EP (GL4) oil if necessary by filling up through plug (B)
(photo 44).
MAXIMUM AMOUNT OF OIL IN GEARBOX :
1 l / 2 US pint / 1.75 Imp pint
NEVER EXCEED THIS QUANTITY.
Check oil level through plug (C) (photo 44) when the
cutterbar is horizontal to the ground. Oil level is correct
when the oil reaches the edge of the hole. When the
cutterbar is in the vertical position, oil can be drained
through plug (C).
CHANGING ROTOR GEARBOX OIL (photos 45 and 45 A)
Change oil of rotor gearbox as follows :
- Disassemble gearbox cover (E) by removing the 4 fixing bolts (G) (photo 45).
- Unscrew drain plug (D) (photo 45 A).
Fill through plug (F) (photo 45 A).
Check oil level through plug (N) (photo 45 A). The level is correct when oil reaches the opening.
MAXIMUM AMOUNT OF OIL IN ROTOR GEARBOX
0,5 l / 1 US pint / 0.875 Imp pint
- 38 -
P.T.O. SHAFTS
Lubricate all PTO shafts with SHELL Multi-Purpose
grease NLGI grade 2 at the hourly intervals indicated in
fig. opposite.
To reach the U-joint grease fitting (rotor side) of the
secondary PTO shaft, disconnect the PTO shaft on the
gearcase side and tilt down the PTO shaft to gain
access to the lubricating hole located in the protection
cover (photo 46).
GREASE FITTING
- Clean fittings before applying grease.
- Grease breakaway sliding components as required.
- Regularly lubricate 3-point frame pivot (E) (photo 46
A)
- After every 50 hours of operation, oil all moving parts
and pivot points.
THE RECOMMENDED GREASE AND OIL CHANGE PERIODS ARE BASED ON NORMAL
FIELD AND WORK CONDITIONS.
SEVERE OR UNUSUAL CONDITIONS MAY REQUIRE MORE FREQUENT LUBRICATION
OR OIL CHANGES.
RESPECT SPECIFIED OIL QUANTITIES AND GRADES : SAE 80 W EP (GL4) OIL
ONLY.
[In certain countries SAE 80 W EP (GL4) oil may not be available. In this case a GL4 or GL5 grade
SAE 80 W 90 oil may be used as a replacement. Never use a straight EP 90 oil].

MAINTENANCE
BEFORE CARRYING OUT ANY OPERATION SUCH AS MAINTENANCE OR ADJUSTMENT
ON THE MACHINE, STOP THE TRACTOR ENGINE, REMOVE IGNITION KEY AND WAIT
FOR ROTATING DISCS AND ROTOR TO STOP COMPLETELY BEFORE LEAVING THE
TRACTOR.
BELT
Belt must be properly tensioned at all times to prevent
excessive slipping and flopping. A loose belt will cause
poor cutting and premature failures.
Check powerband tension as follows :
- Remove belt guard.
- Unlock counter-nut (E) (photo 47) and loosen belt (C)
(photo 48).
- Draw two marks on the belt (A), 1000 mm (39 1/3")
apart (photo 48).
- Tighten adjustment screw (D) (photo 47). Belt ten-
sion is correct when distance between marks (A) is
1007 mm (39 2/3").
- Retighten counter-nut (E) (photo 47) after the adjust-
ment has been made and refit the belt guard.
This precise adjustment should be made when a belt
is replaced and also when retensioning a belt
loosened for storage purposes.
A brief belt tension check should be made after the first
3 hours of use and periodically throughout the season.
To do so it is not necessary to remove the belt guard.
This check is made through the opening (F) located
above the guard after having removed the cover plate
(photo 48A).
Tension is correct when the belt does not deflect more
than 21 mm (4/5") when a force of 28 daN (60 lbs) is
applied mid-way between pulleys onto the whole width
of the belt.
Do not forget to replace the cover plate (P) (photo
48 A) after having made this check.
Note : If damaged, replace the belt :
Part No. 831 116 77 for FC 280 P
Part No. 831 116 78 for FC 240 P
MAKE SURE BELT GUARD IS ALWAYS KEPT IN PLACE.

DISCS AND KNIVES
Discs, knives and securing elements are manufactured from high quality steel and have been subjected to a heattreatment to assure a high resistance to wear.
Worn or damaged items must immediately be replaced with genuine KUHN parts as otherwise warranty will be
withdrawn.
CAUTION : ONLY USE GENUINE
KUHN SPARE PARTS.
Worn knives should either be turned over on the same
disc to use the other cutting edge, or replaced. When
turning or replacing the knifes, make sure there is a 1
mm minimum gap between the knives or their mounting
bolts and the cutterbar wear plates. If otherwise, insert
one (maximum two) distance spacer(s) (code 568 071
00) between the discs and the disc bearing stations
(see fig. 50 A). Dull knives require more horse power to
cut the crop and will leave an uneven stubble. To
replace or turn over knives, first clean the area around
nut (A) (photo 49) and remove nut with the box spanner
supplied with the machine. Ensure securing elements
are in good condition and fit knives so that the arrow on
their upper face is pointing in the direction of rotation of
the disc it is fitted to.
Torque locknut to 12 daNm (90 ft.lbs).
IMPORTANT : ALWAYS REPLACE
SECURING ELEMENTS (LOCKNUTS AND BOLTS) WHEN THEY
HAVE BEEN REMOVED 5 TIMES.
CAUTION : ALWAYS REPLACE
DAMAGED KNIVES, NEVER
STRAIGHTEN A BENT KNIFE.
NEVER REPLACE ONE KNIFE ONLY
PER DISC, ALWAYS REPLACE
BOTH OF THEM TO AVOID CREATING AN OUT-OF-BALANCE FORCE.
Discs are secured by 4 nipple screws (B) and 4 conical
spring washers (C) on a hub (fig. 50).
Two of these diametrically opposite bolts are also used
to secure the conical covers on top of the discs.
Tighten all 4 bolts to a torque of 12 daNm (90 ft.lbs).
The discs must have their largest diameters positioned
at right angles to each other (photo 49). This positioning must be scrupulously respected so as to avoid
interference between the knives. Take extra care when
fitting the conical spring washers (C) (fig. 50), which
must be positioned with the conical centre at the top.

INSPECTION OF KNIVES AND SECURING ELEMENTS
A. KNIVES : Should be inspected
systematically each time before the machine
is operated.
Cutting quality as well as safe operation depend on the
regular inspection and care given to the knives. Knives
should be replaced in the following cases :
1. Damaged knives
Very rough conditions can cause knives to crack
and become deformed leading to :
- increased risk of accidents ;
- deterioration of cutting quality ;
- risk of damage to the cutterbar.
2. Worn knives
Length (A) of a knife should be greater than 65 mm.
The width (B) of a knife, measured at a distance
of 10 mm away from the edge of the disc should
be greater than 34 mm
The hole (L) for the securing bolt must not become
oval by more than 20 mm for an 18 mm hole.
B. SECURING ELEMENTS : To be
inspected regularly !
(particularly the tightening torque of the nut:
12 daNm / 90 ft.lbs).
- Inspect immediately after hitting an obstruction.
- Inspect when replacing knives.
- Check at the beginning of each season.
- 43 -
1. The securing bolt must be replaced:
- When a visible deformation is found.
- When the locking compound on the threads
has worn away or if the locking compound has
become inoperational due to infiltration of water,
oil or dirt.
- When wear on the head reaches the contact
area of the knife.
- When the diameter (D) of the bolt shoulder
is less than 15 mm (5/8 ").
2. The nuts must be replaced :
- When the contact washer has lost its elasticity
or when it becomes loose from the nut.
- When wear on the nut reaches a = 5 mm.
