7) Safety guards
The safety guards protect against acci­dents and therefore ensure maximum machine safety.
On the GF 5000 T, the front safety guards (25) are fitted to the drawbar (26) with 2 hexagon screws (27) (M 8 x
45) and 2 self-locking nuts (M 8) (photo
A). Tighten to a torque of 3 daNm (22 ft.lbs). On the GF 5000 M, support (2) of front safety guards (3) is fitted to the connecting frame using 2 hexagonal bolts (1) (M 10 x 30) and 2 self-locking nuts (4) (M 10) (fig. B) (torque : 8 daNm ­59 ft/lbs). Then fit 2 front safety guards (3) onto support (2) by means of 4 hexagonal bolts (18) (M 8 x 45) and 4 self-locking nuts (17) (M 8) (fig. B) (torque : 3 daNm - 22 ft/lbs). The side guards (11 and 12) are fitted to the outer rotor housings using 2 hexagon screws (16) (M 12 x 25) and 2 conical spring washers (14) (M 12). They are also fitted to the flanges of the outer tubes using the 2 self-locking hexagonal bolts (15) (M 12 x 40) (fig. C). Tighten the screws (16 and 15) to a torque of 10 daNm / 75 ft/ lbs) (photo 7).
Reflectors (6, 8) (GF 5000 M) or (19) (GF 5000 T) are to be fitted on supports (7, 21) using bolts (9) (M 5 x 35) or (20) (M 5 x 25) and self-locking nuts (5) (M 5), as shown on figure B.

ATTACHMENT
ATTACHMENT TO THE TRACTOR
1. GF 5000 M
The GF 5000 M Gyrotedder can be fitted to all tractors equipped with a 3-point linkage. The lower link pins are 22 mm diameter and 28 mm diameter for tractors with Cat. 1 and 2 linkage. The lower link pins (O) should be attached to the tractor link arms (P) inside the 3-point frame for Cat.1 tractors and on the outside for Cat. 2 tractors. In the latter case, use the 25 mm diameter link pins to attach tractor top link (Q) to the pivoting top link (B) (photo 10). Attachment should be undertaken with the pivoting top link (B) unlocked (lever V in the lower position, photo 11). The pivoting top link has three attachment positions to suit varying tractor top link lengths.
- 14 -
2. GF 5000 T
The GF 5000 T gyrotedder can be fitted to all types of tractors, preferably those with a pull bar. Attachment is facilitated when the machine is resting on its parking stand (A). Fold up parking stand (A) and lock in place with the clip (G) (photo 12).
When attaching the machine to a tractor equipped with a multi-hole attachment bar on the 3-point linkage, make sure the tractor lower links are locked in a fixed posi­tion preventing them from moving upwards.
PTO SHAFT
Connect the PTO shaft (with the safety clutch fitted on the machine side) (photos 10 and 12).
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 (photos 13 and
14). Bevel and clean the tubes (photo 15) and grease the inside of the outer tube (photo 16).
- 15 -
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 chain (photos 10 and 12). Damaged guards should be replaced immediately.

- 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.
It is difficult to give accurate recommendations concerning operating speeds as these must be chosen in accordance with the crop being worked. However, as a general rule, if the crop is dry, rotor speed
(rotational frequency)
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 adviseable to lower the forward speed and increase the PTO speed
(rotational frequency)
.
TRANSPORT POSITION
1. GF 5000 M
- Disconnect the tractor PTO shaft.
- Lower the machine to the ground.
- Release lock (X) (photo 17) and fold
back the outer rotors until the locks automatically reengage in the trans­port position.
- Lift the machine and lock the pivoting
frame (B) by lifting lock (V) (photo
24).
Never engage the PTO shaft when the machine is in the transport position.
NOTE : Before moving the GF 5000 M when having been parked in the transport position, unlock the outer wheels to allow them to pivot.
2. GF 5000 T
- Disconnect the tractor PTO shaft.
- In order to fold the machine correctly,
position the rotors horizontally using crank handle (M) (photo 22).
- Release locks (X) (photo 17) and fold
back outer rotors until the locks automatically reengage in transport position.
- Lock outer rotor wheels (R) in posi-
tion holes (Y or Z, photo 21) so that the levers (F) point forwards (looking in the direction of travel) (photo
25). The central wheel lever (F) should point towards the rear (looking in the direction of travel) (photo
25).

LUBRICATION
Grease the following points with
SHELL Multi-Purpose grease NLGI grade 2 :
- Once a day :
*The 2 coupling sleeves (M) (photo 27). *Universal joints and PTO shaft tubes.
- Once a week :
*The 4 rotors and 2 toggles (R) (photo 27); *3-point frame pivot (B); *Vertical articulation pin (J) (photo 24). *4 wheel axles (A) (photo 19). *4 levers (H) (photo 19). *The angle adjustment crank handle and its articulation (on the GF 5000 T).
- Once a year :
*4 rotor housings.
- Next, in order to prevent the outside
rotor tines touching the inner rotor tyres (risk of puncture), lock one tine arm (B) of each outside rotor using clips (L) (photo 26).
Do not forget to lift lock clips (L) (photo 26) when changing the GF 5000 T into its working position.
Never engage the PTO shaft when the machine is in the transport position.
Never transport the GF 5000 T at over 25 km/hr (16 mph).
To avoid the tines puncturing the tyres of the inner rotors when the GF 5000 is in the transport position (with outer rotors folded back), always ensure that the inner wheels are locked in their forward position (photos 19 and 20) before folding the outer rotors to the rear.

OPTIONAL ACCESSORIES
1. Reduction gearbox (kit no. 111 6440)
A «Duplex» reduction gearbox for the GF 5000 M / T 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 standard GF 5000 M / T’s without modification. To install the «Duplex» reduction gearbox proceed as follows :
- 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 spring washers (photos 28 and 28 A) (torque : 9 daNm - 65 ft/lbs). The spacer washer delivered with the kit has to be fitted on the lower screw (S) between bracket (K) and central gearbox (R) on the GF 5000 T (photo 28 A).
- Fit the retaining ring (O.D. 35) 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 (photos 29 and 29 A). In this case the tractor PTO speed
(PTO 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 stub not in use is fully guarded (photos 29 and 29 A).
The drive gearbox is filled with SHELL Multi-Purpose grease NLGI grade 2. Only refill gearbox after repair (capacity : 0.8 kg/1.80 lbs).
Lubricate the following points with SHELL OIL :
- Once a day :
*The 2 stop plates (C) and the 4 drive cam rollers (S) (photo 27). *The 2 limiting bars (L) (photo 27) on the GF 5000 M.
- Once a week :
*The 2 outside rotor locks (X) (photo 27). *The wheel height adjustment cams (E) and wheel position locks (G) (photo 19). *The 3-point pivot lock.
