The weighted root mean square acceleration to which the whole body is subjected to ranges from 0.9 to 1.05 m/s (where s is squared) as measured on a representative machine during field operations, and analyzed in accordance with ISO 2631. During the same operations, the weighted root mean square hand-and-arm vibration was less than 2.5 m/s (where s is squared) when analyzed in accordance with ISO 5349. These acceleration values depend on the roughness of the ground, the speeds at which the cotton picker is operated, the maintenance of the machine, and the operator's experience, weight, and driving habits.

The A weighted sound pressure levels inside the operator's station ranges from 81.7 to 83.6 dBa as measured in accordance with ISO 5131. These sound pressure levels depend upon the speed at which the cotton picker is operated, as well as the condition and maintenance level of the picker.
