ibration Referred to the Operator Positio
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.
The following best practices should be observe to minimize whole-body vibration
Always use the most appropriate implement for the relevant type of work.
Adjust the seat to match your weight and seating position.
Check the cab suspension periodically and replace if damaged.
Check tire pressure.
Use the front axle suspension, if fitted.
During transport, adjust the tractor speed to minimize vibration levels.
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
