• We recommend a speed of 7 to 8 km/h (4.4 -
5 mph).
- When tedding a more or less dry crop.
• We recommend a speed of 8 to 10 km/h (5 -
6.3 mph).
The dryer the crop, the more the P TO 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.
