ATTACHMENT
FITTING TO THE TRACTOR
The GF 5001 MH can be fitted to all tractors equipped with a DIN or ASEA Standard 3-point linkage. The lower
link pins are 22 mm and 28 mm diameter for tractors with Cat. I and II linkage. The lower link pins should be attached
to the tractor link arms (P) inside the 3-point frame for Cat. I tractors and on the outside for Cat. II tractors. In the
latter case, use the 25 mm diameter link pins to attach tractor top link (Q) to the pendulum arm (A) (photo 11).
Attachment should be undertaken with the pendulum arm (A) unlocked (lever V in the lower position, photo 12).
The pendulum arm has three attachment positions to suit varying tractor top link lengths.
Connect hydraulic hose (R) to a female hydraulic connection at the rear of the tractor (photo 11).
When the machine is attached to the tractor, raise stand (D) and secure with spring cotter (O) (photos 11 and 12).

PTO SHAFT
Connect the PTO shaft to the 540 rpm (min-1) tractor drive (with the safety clutch fitted on the machine side) (photo
11).
Make sure PTO length is correct :
1) When the PTO is in its maximum extended position, a minimum tube overlap of 300 mm (12") 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 2 cm (0.8") must be maintained. If this is not the case, shorten the two
transmission tubes and the two guard tubes by the same length (fig. 13 and 14). Bevel and clean the tubes (fig.
15) and grease the inside of the outer tube (fig. 16).
3 ) Never operate the PTO at too great an angle (30° maximum).
These recommendations and adjustments must be respected to avoid damage or premature wear of
the PTO.
Never connect the PTO to the 1000 rpm (min-1) 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 (photo 11). On machine side the safety chain must
be attached to the frame (photo 24, page 23). Worn or damaged guards must be replaced
immediately.
- 19 -
Rotor angle is adjustable in 2 different positions :
1 ) Maximum working angle is obtained when handle (L) is facing upwards (photo 18).
2 ) Minimum working angle is obtained when handle (L) is facing downwards (photo 19).
Maximum working angle should be used for first cut (normal or particularly dense crops).
For second and third cuts (medium density and light crops) the minimum working angle position should be used.
To change the machine from the transport position to
the work position, proceed as follows :
- Lower the machine on the ground,
- Unlock pendulumarm,
- Free the outside rotors by releasing locks (L). Next
turn these rotors 180° so that their tines point towards
the outside. Make sure that the locks (L) will
automatically lock into the working position (photo
17).
- Activate the tractor hydraulics to put hydraulic
cylinders (V) under pressure.
- Release locks (R) (photo 17) from the tractor seat by
pulling cord (C).
- Lower the outside rotors by releasing pressure.
When tedding, the tractor 3-point linkage should always
be in the free floating position.
Never engage the tractor PTO when
the outside rotors are folded into
transport position.
WORKING POSITION AND ADJUSTMENTS
- 20 -
Adjustment of handle (L) with eccentric (E) (photo 20) is carried out as follows :
- Machine is attached to the tractor, stand in front of one of the rotors
- Pull eccentric (E) out of its housing and turn lever (L) 180° upwards or downwards
- Lift or lower handle (K) so that the eccentric (E) is in alignment with its housing and is re-engaged automatically
by return spring (I) (photo 20).
Proceed the same way on the remaining rotors.
Perfect rotor angle adjustment using tractor crank handle so that the tines lightly skim the ground at the front of the
machine.
When working along edges of fields, hedgerows, fences, etc., the oblique position is obtained by locking the
wheels in holes (H) to project the crop towards the left or holes (J) to project the crop towards the right (photo 21).
Hole (N) corresponds to the regular work position (photo 21). Wheels are locked in the selected position by means
of locks (P) (photo 21). Positions (U) and (V) are never used on the GF 5001 MH (photo 21).
If at the field ends the tractor does not lift the machine high enough to clear the outside rotors from the ground, it
is possible to lift the rotors slightly using the hydraulic cylinders (see photo below).Do not forget to put again the
tractor 3 - point linkage in the free floating position.
- 21 -
OPERATING SPEED
Many factors govern the choice of the correct forward speed :
1) The moisture content (this factor is most important the first time over).
2) The density of the crop.
3) The height and type of crop.
Here are a few examples of correct speed given a crop of average length and density :
- First time over : when the crop has a high moisture content, the speed is approximately 7 - 8 km/hr (4 1/2 -
5 mph)
- Second time over : the speed can reach 10-12 km/hr (6 1/2 - 7 mph) according to the moisture content.
If the hay is dry the speed (rotational frequency) of the rotor should be reduced. When the crop is very long, heavy
and wet, the forward speed should be reduced. In difficult conditions such as these it is generally advisable
to lower the forward speed and increase the PTO speed (rotational frequency). It is impossible to give
accurate information on this, the speeds must be decided according to the crops being treated.
- 22 -
TRANSPORT POSITION
To fold the machine in transport position, proceed as
follows :
- Disengage the PTO.
- Wait for all movement to stop.
- Pull cord (C) (photo 22).
- Activate the tractor hydraulics and lift the outer rotors
until locks (R) automatically lock into the transport
position (photo 22).
- Unlock outside rotors by means of locks (L) (photo
22) and turn them 180° so that their tines point
towards the centre (looking from behind the machine).
Make sure the locks (L) will automatically relocate in
the transport position (photo 22).
- Raise the machine, lock the pendulum arm (A) by
means of lock (V) (in its upper position). (See
photo 23).
- Ensure that stand (D) is locked in its raised position
with spring cotter pin (O) (photo 23).
Never engage the tractor PTO while
the machine is in the transport position.
Keep all persons away from the vicinity of the machine before pivoting the outer rotors into
work or transport position.

- 23 -
PARKING THE MACHINE
The 3-point frame is provided with a parking stand (D) to allow this machine to be parked whether in its transport
or working position (photo 24). PTO shaft (T) should be positioned in its support (S) to avoid ground contact which
could result in premature failure due to contamination with dirt and dust (photo 24).
Put male coupling of the hydraulic hose (F) into its parking support (H) (photo 24).
If ever the GF 5001 MH is to be parked whilst in its transport position, an area must be used
where the ground is very even and level. Wedges must always be placed under the 2central
wheels (photo 24).

OPTIONAL EQUIPMENT
1) 3-POINT FRAME EXTENSION
(Kit No 114 6230) (photo 28)
For tractors with limited linkage possibilities, two
extensions (R) can be fitted to the 3-point frame (C),
enabling the machine to be lifted higher during transport.
2) DUPLEX REDUCTION GEARBOX (Kit No 111 6440)
A «Duplex» reduction gearbox for the GF 5001 MH can be supplied as an optional extra when using the machine
for raking night swaths. With this gearbox, the high rotor speed (rotational frequency) necessary for tedding and
turning is maintained and there is also a lower rotor speed (rotational frequency) for raking night swaths.
The reduction gearbox can be attached to existing GF 5001 MH’s without modification. To install the «Duplex»
reduction gearbox proceed as follows :
- Fit guard (G) (photo 30) on Duplex reduction gearbox,
using the hardware provided therefore.
- Remove original PTO shaft guard from the central
gearbox.
- Slide the Duplex reduction gearbox unit (Q) on the
drive shaft from the central gearbox (R) and secure in
place with 2 self-locking screws (S) (M 12 x 40) and
2 conical spring washers (photo 29) (torque : 9 daNm
- 65 ft.lbs).
- Fit the retaining ring (35 E) delivered with the kit on the
drive shaft from the central gearbox.
When tedding, the PTO shaft must be fitted directly to
the splined end of drive shaft. When raking night
swaths, mount the PTO shaft on the «Duplex» reduction gearbox input shaft (photo 30). In this case the
tractor PTO speed (rotational frequency) should be
maintained at 400 rpm (min-1) and ground speed
between 5-7 km/h (3-4 miles/h). Mount the PTO shaft
cover (E) inside the guard (G) using wing nut (H) so that
the PTO end not in use is fully guarded (photo 30).
