Projection of stones and foreign objects
For driver safety, always use a tractor equipped with
a cab. Keep the ground to mow free of foreign
bodies. Avoid mowing on stony or rocky grounds. If
this is not possible, take extra safety precautions,
such as
- Fit polycarbonate screens inside the tractor cab's
side and rear windows, or install narrow mesh
guards on their exterior.
- Increase the cutting height to avoid contact with
stones or rocks.
Never start a mower conditioner when other people
are close.
Even when the machine is used properly, objects
may be thrown. Stones and other foreign objects
thrown by the moving parts can travel a
considerable distance. Keep all persons and
animals away from the danger zone.
The protection covers help reduce risks of
