In order to minimize the vibration transmitted to the whole-body the following
best practice rules should be observed:
• Use the most suitable implement for the tractor and the task in hand
• Adjust the seat to suit your weight and stature
• Periodically check the condition of the cab suspensions and renew them if
damaged
• Check tire inflation pressure
• Use front axle suspensions, if fitted
• During transfers, adjust tractor speed in order to minimize the vibration level.
The seat vibration values, as obtained from the seat approval in compliance with 78
/764/EEC (amended by 1999/57/EC) are shown in the following table.
Technical data:
Input vibration : Category A, Class I ,II and III
Ambient temperature : 23℃
The value is referred to the amount of
mechanical vibration transmitted by the
tractor to WHOLEBODY as defined by
UNI ISO2631-1:2008.
Said value must be utilized for
assessment of the vibration exposure
risk, but it cannot cover all the possible
conditions of use of the tractor since it
may vary in accordance with
parameters that are not always related
to the tractor (terrain, implements, etc.)
If the risk assessment cannot be
considered to be exhaustive or if the risk
may may exceed the values defined in
2002/44/EC, the use of a vibration mater
s prescribed.
