The tractor PTO stub must rotate at a speed of 540 min Separate the two half PTO shafts and connect them to
the machine's input shaft and to the tractor PTO stub. Check the length of the PTO shaft:
- Check the maximum overlap when the machine is in work position and the tractor turned to the direction which provides maximum overlap.
- When the PTO shaft is in its maximum overlap position (retracted), tubes should not butt against the yokes. As a safety measure, a clearance (L) of at least 25 mm (1’’) must be maintained.
- When the PTO shaft is in its maximum extended position, the tube overlap must be more than 250 mm (10’’).
If this is not the case:
• Mark length (H) to cut when the transmission is the
maximum overlap position
• Shorten the guard tubes and the transmission tubes
by the same length.
• Bevel and clean the tubes.
• Grease the inside of the outer tube.

.
Gyrotedder
GF222T
The following factors determine the forward speed:
- The humidity level (This factor is particularly determining when wilting).
- The crop density.
- The crop composition (blade length).
- The ground contours.
General advice:
In dense and average length crop:
- When wilting a crop with low humidity level.
• the speed is approximately of 7 to 8 km/h (4.4 -
5mph).
- When tedding a more or less dry crop.
• the speed is approximately of 10 to 12 km/h (6.3 -
7.5 mph).
• The dryer the crop, the more the PTO speed must
be reduced.
• For a very dense, humid crop composed of very
long blades, the forward speed must be reduced.
For difficult working conditions, it is recommended to operate at a lower forward speed.
