"The seat vibration of nine tractors was investigated while harrowing was being performed. In all cases, the average vibration of the seat exceeded the 8h "fatigue-decreased proficiency boundary" specified in the international standard ISO 2631/1. The instantaneous accelerations of the most harmful one-third octave band of vibration were sometimes two- to threefold compared with the average. More technical development is needed to reduce seat vibration to a safe level. Topics: agricultural operations; back disorders; backache; drivers; tractors; vibration acceleration; vibration measurement; whole-body vibration."
