Valtra T174e A User Manual

6.13.5 Exposure to vibration
The level of exposure to vibration and shock is dependent on several issues,
such as work tasks, tyre types, work conditions and implements. Always plan
your work so that the exposure is minimised. In extreme conditions, keep warm
and dry and try to take short breaks.
The vibration measurements are based on Directive 78/764/EEC.
