MacDon M105 Operator's Manual page 4

Whole Body and Hand-Arm Vibration Levels
The weighted root mean square acceleration, to which the whole body is subjected, ranges from 0.57 to 1.06 m/s
2
as measured on a representative machine during typical operations and analyzed in accordance with ISO 5008.
During the same operations, the weighted root means square hand-arm vibration was less than 1.45 m/s 2 when
analyzed in accordance with ISO 5349. These acceleration values depend on the roughness of the ground, the
speeds at which the windrower is operated, the operator's experience, weight, and driving habits.
Noise Levels
The A-weighted sound pressure levels inside the operator's station ranged from 70.1 to 73.1 dB(A) as measured
on several representative machines in accordance with ISO 5131. The sound pressure level depends upon the
engine speed and load, field and crop conditions, and the type of platform used.
