Vibration Stress

All operator's seats approved by John Deere are authorized by type acc. to 78/764/EEC with an arithmetic mean of the effective values of the evaluated vibration acceleration at the seat (a_wS) of ≤ 1.25 m/s^².

This value must NOT be used to calculate vibration stress as per 2002/44/EC! To determine the vibration stresses, the local authorized dealer can provide appropriate help.

Vibration reducing measures can be for example:

• Appropriate driving styles such as a proper speed
• Suspended front axle
• Suspended cab
• Correctly adjusted operator's seat
• Correct tire pressure
