SPECIAL SAFETY RECOMMENDATIONS

1. Use a tractor equipped with an enclosed cab with windows made of safety glass and kept closed. It is

recommended to fit polycarbonate screens inside the tractor safety cab's side and rear windows or to install mesh
guards on the exterior of them.

2. Stay a safe distance away from the mower when discs are rotating.

3. For safe machine operation, it is imperative that cutting tools be fitted in accordance with the manufacturers

recommendations. Use only the tool outfit supplied with the machine.

4. Each time before using the mower, inspect condition of cutting elements (knives, discs). Replace any missing,

worn or damaged cutting elements immediately. Use only genuine KUHN spare parts.

5. To avoid creating dangerous out of balance forces, always replace missing, damaged or worn knives in pairs.

6. When replacing knives or discs, systematically inspect their securing elements as per the manufacturers

recommendations.

7. Regularly inspect the disc mowers protection cover. Worn or damaged protection covers must be replaced

immediately.

8. Protection devices (such as guards, shields etc.) are intended to prevent stones, rocks or other foreign objects

from being projected. They also prevent access to the machines danger zones. Therefore, it is imperative that
protection devices are put in place and properly secured each time before using the machine.

9. Crushing and shearing zones which could cause serious bodily injury when changing the machine from transport

to work position and vice versa may exist. To prevent possible injury, be extra careful when maneuvering and
ensure that everyone is at a safe distance away from the machine.

10.PTO drive to the mower must never be engaged unless the cutterbar skid shoes are in contact with the ground

and the protective cover is folded down.

11.Ground of the pastures to be mown must be free of foreign objects.

12.Even when the machine is used in accordance with its purpose, objects may be projected. It is therefore

imperative that everyone be kept away from the danger zone, that extra care be taken and that extra precaution
(such as safety indicators) be taken when mowing pastures alongside roads or near public areas (parks, schools
etc.).

13.Never mow in reverse.

14.When disengaging the PTO drive, moving parts continue to rotate for some time. Wait for all moving parts to come

to a complete stop before approaching the machine.

15.If an obstruction is hit, stop the tractor immediately, disengage PTO drive, turn off engine, remove ignition key

and wait for all moving parts to come to a complete stop.

P.T.O. SHAFT

These recommendations and adjustments must be respected to avoid damage or premature wear of
the PTO.

Never connect the PTO to the 1000 rpm tractor drive.

To avoid accidents which could be serious, make sure that the guards are always correctly in place
and secured with the safety chains (x) (photo 22). Damaged guards should be replaced immediately.

Connect the PTO shaft to the 540 rpm tractor drive (with the free wheel fitted on the machine side).

Make sure PTO length is correct :
1° When the PTO is in its maximum extended position, a minimum tube overlap of 250 mm (10") must be maintained.
2° When the PTO is in its maximum overlap position (retracted), tubes should not butt against the yokes. As a safety

measure a clearance of at least 10 mm (2/5") must be maintained. If this is not the case, shorten the two
transmission tubes and the two guard tubes by the same length (photos 18 and 19). Bevel and clean the tubes
(photo 20) and grease the inside of the outer tube (photo 21).

3° Never operate the PTO at too great an angle (30° maximum) (photo 22).

- 21 -

TRANSPORT

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 highways or from one field to another, proceed as follows :

- Disengage the PTO drive and wait for all movement to stop.

- Raise the machine with the tractor 3 point linkage.

- Release lock by applying pressure with the box spanner (A - arrow 1) supplied with the machine and fold the front
safety bar upwards (arrow 2) (photo 24) till it is automatically locked in transport position.

- Pull cord (F) (photo 25) to pivot stop plate (G) which locks the spring compensating system.

- Raise cutterbar in the full vertical position, keeping cord pulled until cutterbar is raised up. It will automatically be
locked in place by latch (C) (photo 25) when it reaches the vertical position (photo 26).

The cord (F) (photo 25) must be pulled each time when raising the cutterbar in the vertical
position.

Note : It is normal that the vent plug may seep lubricating fluid during the first activations of the hydraulic cylinder.

- 22 -

WARNING : BEFORE PUTTING THE MACHINE IN WORK OR TRANSPORT POSITION, ENSURE
ALL PERSONS ARE WELL CLEAR OF THE CUTTERBAR PIVOTING AREA.

1. Pressurize the disc mower's lift cylinder so that the cutterbar closes up against its stop.

2. Pull cord (F) to free latch (C) (photo 27).

3. Lower the cutterbar down to the horizontal position by releasing hydraulic pressure. Keep cord pulled until

cutterbar is lowered half-way, as cord also activates stop plate (D) which unlocks the spring compensating
system.

4. Release lock by applying pressure with the hand palm (arrow 1) and fold front safety bar (V) downwards

(arrow 2) (photo 28) till it is automatically locked in working position.

Adjustment of chassis height from the
ground

1. For tractors equipped with hydraulic position
control function, set position control so that lower

hitch pins are 450 mm (18") from the ground (photo

29).
In this case the stop chain delivered with the
machine must not be used.

WORKING POSITION AND ADJUSTMENTS

- 23 -

CUTTING HEIGHT

Maximum cutting height (50 mm / 2") (fig. 1) 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 (H) (photos
29 and 30) 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 then 30 mm
/ 1 1/4" (fig. 2).

2. For tractors not equipped with hydraulic
position control function the stop-chain delivered
with the machine must be used.

- Lower machine until hitch pins (F) are 450 mm (18")

or slightly more from the ground.

- Connect stop-chain (D) with its hook (G) supplied in

the hardware kit of the machine to one of the free
holes at the tractors top link attachment clevis.

- Lower the machine into working position. Chassis

height is correct when :

- The cutterbar is resting on the ground.

- Stop-chain (D) is tight.

- E = 450 mm (18") (distance of lower
hitch pins from ground).

- To keep this adjustment permanently, close hook
eyelet with roll pin (dia. 5 x 45 mm).

WARNING : BEFORE PUTTING THE MACHINE IN WORK OR TRANSPORT POSITION,
ENSURE ALL PERSONS ARE WELL CLEAR OF THE CUTTERBAR PIVOTING AREA.

- 24 -

SAFETY BREAK-AWAY

A breakaway latch allows the cutterbar to swing back
if an obstruction is hit (photo 31).
IF THE LATCH RELEASES, STOP THE TRACTOR
IMMEDIATELY AND DISENGAGE THE PTO.
To reset the cutterbar, back the mower 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, the break-away
linkage must be checked for good operation making
sure all components slide correctly and are well
greased. Check for any cutterbar damage if an obs­truction is encountered.

For the GMD 600 and GMD 700, the stack of spring washers should be compressed to 95 mm ( 3 3/4") (fig. 3).
Observe spring-washer arrangement in fig. 3 (photo 32) carefully.

If after resetting, the cutterbar continues to break away, the pressure of spring assembly (A) (photo 32) can be
increased, but in all cases stacking must not be less than 91 mm (3 2/3"), as otherwise safety disengagement cannot
function.

- 25 -

PARKING THE MACHINE

BEFORE ATTEMPTING TO LOWER
THE PARKING STAND, RAISE THE
CUTTERBAR TO ITS VERTICAL
TRANSPORT POSITION, TO RELEASE
ALL PRESSURE ON THE
COMPENSATING SPRING.

- Pull parking stand control lever (L) and pivot it to the
right which lowers stand (E) and at the same time
unlocks compensating spring (P).
This second operation is completed by cable (S)
releasing stop (R).
Lever (L) will automatically lock into place when fully
pivoted towards the right.

- Release hydraulic pressure to lower cutterbar to the
horizontal position (see page 22 for correct proce­dure).

- With the hydraulic 3-point lift, lower the machine to
the ground and disconnect the top link and the
hydraulic hose.

- Then disconnect lower links and the PTO shaft.

- Place the PTO shaft (T) in its support (U) and wind the
hydraulic hose around the top link clevis (photo 34).

FOR YOUR SAFETY : ALWAYS PARK THE MACHINE WITH THE CUTTERBAR IN THE
HORIZONTAL POSITION.

- 26 -

OPERATING THE MOWER

Release lock by applying pressure with the hand palm
(arrow 1) and fold front safety bar (V) downwards (arrow

2) (photo 35) till it is automatically locked in working
position.

ENSURE THAT THE SAFETY
CURTAIN IS COMPLETELY IN
PLACE AROUND THE CUTTER­BAR.

Safety curtain will avoid projection of most foreign
objects.

Always allow a few minutes for oil to spread in the
cutterbar before engaging PTO when changing cutterbar
from transport to operating position.
Before cutting, engage tractor PTO and slowly increase
speed up to 540 rpm.
Do not be disturbed by the high pitched whine of the
discs. This will be reduced to some extent when
cutting.

Forward speed must be adapted to working conditions and should be reduced when mowing dense crops.
Check correct fixation of plugs (C) (photo 35) on the outer and inner disc cone.
Replace lost or worn plugs immediately.

ADVERSE FIELD CONDITIONS

NEVER MOW IN STONY OR ROCKY GROUNDS.

Extra care and precautions should be taken in rough or debris-ridden fields. The following adjustments should be
made to the mower in these conditions to minimize the possibility of foreign objects being deflected by the cutting
knives.

1° Tilt the angle of the cutterbar back towards the horizontal position by turning the top link handle (H) (photo 29,

page 22 and photo 30 page 23) to raise the cutting height of the knives.
2° Reduce the forward speed.
3° Make sure the cutting knives can pivot if an obstruction is hit.

NEVER OPERATE THE MOWER WITHOUT THE PLASTIC COVER IN PLACE. DO NOT
LEAN AGAINST OR STAND ON THE GUARD COVER.

LUBRICATION

NOTE : Provided above intructions 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 : Before carrying out this check, turn off the tractor engine, remove ignition key and disconnect the PTO
shaft.

To drain oil, remove magnetic drain plug (E) (photo 37) located underneath the cutterbar below the bevel gearbox.
Clean all metal particles off the magnetic drain plug before refitting.

IMPORTANT : It is very important that the oil in the
bevel gearbox and the cutterbar be changed after the
first ten hours of use with E.P. SAE 80 GL4 OIL.
Thereafter, it should be changed every 200 hours of
use or at least once per year.
NOTE : Oil should be drained immediately after use
while still warm.
The pressure relief valve (A) (photo 36) located on the
side of the bevel gearbox must also be unscrewed and
cleaned after the first ten hours and thereafter should
be checked and cleaned regularly. The ball detent
must be free to relieve pressure.

1° BEVEL GEARBOX

Check oil level once a day . Add oil through filler plug
(B) (photo 36) if required.
The maximum oil capacity of this gearbox is as shown
in the table below and it is important not to exceed

this quantity.

GEARBOX OIL CAPACITY :

0.45 litre - 1 US pint - 0.75 Imp. pint

Plug (C) (photo 36) serves as a check plug when the
bar is horizontal. Remove plug (C). When oil level is
correct, it will just begin to flow out of the hole. Plug (C)
is also used as a drain plug when the cutterbar is in the
vertical transport position.

2° CUTTERBAR

Check oil level once a day. Add E.P. SAE 80 GL4 oil
to the cutterbar at fill plug (D) (photo 37). The oil level
is correct when oil flows out of the fill plug hole.
Note : Make sure the cutterbar is in the vertical
position when checking or adding oil.

CUTTERBAR OIL CAPACITY :

2.00 litres - 3.5 Imp.pints - 4.25 US pints

- 28 -

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.

GREASE FITTINGS

Clean fittings before applying grease. Oil all pivot and
linkage points every fifty hours.
Grease breakaway sliding components as required.

Lubricate the PTO shaft at the hourly intervals indicated
in figure 1 with SHELL Multi-Purpose grease NLGI
grade 2

ADJUSTMENTS AND MAINTENANCE

Adjust machine to clear obstructions and debris. Foreign objects and other debris can be
deflected toward the operator and bystanders.

1. Discs and knives

To replace or turn over knives, first clean the area
around nut (A) (photo 38) 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).

Discs, knives and securing elements are manufac­tured from high quality steel and have been subjected
to a heat-treatment 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. 2, page 29). Dull knives require more
horse power to cut the crop and will leave an uneven
stubble.

(In certain countries SAE 80 W EP (GL4) oil may not be available. In this case a GL 4 or GL 5 grade SAE 80 W
90 oil may be used as a replacement. Never use a straight EP 90 oil).

- 29 -

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. 1).
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. 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. 1), which must be positioned with the conical centre
at the top.

Discs supplied through our spare
parts department come with a 1 mm
spacer (part no. 568 071 00) (fig. 2)
attached to them. When installing a
new disc check if the gap between
the blades or their mounting bolts
and the cutterbar protection shields
is at least 1 mm. If this is not the case
fit the 1 mm spacer between the disc
and its mounting hub for increased
clearance (fig. 2).

CAUTION : BEFORE CARRYING OUT SERVICE OR ADJUSTMENTS TO THIS MACHINE, TURN

OFF THE TRACTOR ENGINE, REMOVE IGNITION KEY AND DISCONNECT THE PTO SHAFT.

- 30 -

2. Belts

Belts must be properly tensioned at all times to avoid
excessive flopping and slipping. Loose belts will also
cause poor cutting and premature wear.
To tension the belts, loosen lock-nut (E) and tighten
screw (D) (photo 39). When belts have been tensioned
correctly, retighten the lock-nut.

Belt tension is correct if deflection does not exceed 10
mm (2/5") when a belt is pressed upon with a force of

3.5 kg (8 lbs) at mid distance between pulleys. This
must be checked, particularly during the first hours of
work, through the cut-out (C) located underneath the
belt shield (photo 40).

Note : Belts must never be changed individually. If

one of them becomes damaged, the whole set
(code No. 83101791) must be replaced.

3. Releasing compensating spring

(photo 41)

When parking the machine, the compensating spring
is automatically released by operating the parking
stand control lever which also activates the transport
lock through cable (S), allowing the shouldered rod (F)
to slide freely in its guide (G). Length of cable (S) can
be adjusted by using screw (V), if necessary.

- 31 -

4. Adjustment of compensating spring

tension

REGULARLY CHECK ALL NUTS AND BOLTS FOR CORRECT TIGHTNESS,
PARTICULARLY THOSE SECURING THE DISCS AND KNIVES.

The compensating spring is factory adjusted so that
dimension (X) (photo 42) is 200 mm (8") for the GMD
600 and 170 mm (7") for the GMD 700.

When working conditions are difficult, adjustment can
be modified as follows :

- Put machine in parking position, which releases

compensating spring (P) (photos 41 and 42).

- Loosen lock nut (H) and adjust rod (F).

- After adjustment retighten lock nut (H).

- 32 -

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.

INSPECTION OF KNIVES AND SECURING

ELEMENTS

- 33 -

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 inclusion 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.
