INFORMATION PAGE ON VIBRATION LEVELS OF THE TRACTOR
EXPOSITION TO VIBRATIONS [4.4]
WARNING: The vibration level transmitted
to the body as a whole depends on different
parameters, some of them relating to the
machine, others to the terrain, others to the
type of work and to any connected machine
and many specific for the operator. The pre-
vailing parameters are the type of terrain
or work surface, the ground speed and the
type of work.
WARNING:
Machine vibrations are transmitted to the
operator, who in some cases may undergo
risks for his/her health and safety. Therefore
you must:
- Make sure that the tractor is in good condi-
tion and that all routine servicing is correctly
and regularly carried out.
- Check that the operator ’s seat and
adjustment systems are in good condition,
then adjust the seat to the operator’s weight
and size.
- Evaluate the vibration level transmitted
to the operator from the tractor or from the
tractor-machine assembly and schedule work
hours so as to alternate suitable rest periods
concerning exposure to vibrations.
IMPORTANT: More information on Whole Body Vibra-
tion (WBV) on agricultural tractors can be found in more
specific publications. In order to correctly estimate
values based on your daily work on the tractor, a specific
measure instrument is required, such a three-axis accele-
rometer applied to the seat.
NOTE: Visit the dedicated Internet web sites for further
information and documentation on risks of whole body
vibration.
