Vibration Referred to the Operator Position
The value is referred to the amount of mechanical vibration transmitted by the tractor to WHOLE-BODY as
defined by UNI ISO2631-1:2008.
Said value must be utilised 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.
In order to minimise the vibration transmitted to the whole-body the following best practice rules
should be observed
z
Use the most suitable implement for the tractor and the task in hand.
z
Adjust the seat to suit your weight and stature.
z
Periodically check the condition of the cab suspensions and renew them if damaged.
z
Check tyre inflation pressure.
z
Use front axle suspensions, if fitted.
z
During transfers, adjust tractor speed in order to minimise 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.
Input vibation : Category A, Class I and Class II
Ambient temperature: 23 °C
Seat type Corrected vibration level on seat
