3. Machine use
Groundspeed
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 high humidity level.
• the speed is approximately of 7 to 8 km/h (4.4 -
5 mph).
- 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.
Gyrotedder
GF10802T
For difficult working conditions, it is
recommended to operate at a lower forward
speed.
Driving the machine
When turning while tedding on field edges,
the turning angle must not exceed 60° with
regards to the direction of travel.
