Precautions when driving
Tractor handling, stability, performance and braking
efficiency are all affected by weight distribution, trailed or
mounted implements, additional ballast and driving
conditions. It is therefore of the great importance that the
operator exercises caution in every given situation.
Groundspeed must be adapted to ground conditions as
well as to roads and paths. Always avoid abrupt changes
of direction.
Be particularly cautious when turning corners, paying
attention to machine overhang, length, height and
weight.
Never use a narrow track tractor on very uneven or
steeply sloping ground.
Never leave the tractor seat while the machine is
operating.
Carrying people or animals on the machine when
working or in transport is strictly forbidden.

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.
Below are a few recommendations for your information:
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 can reach approximately 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.
