Sound Measurements

Averaged Sound Level at Work Station According to ISO11201:1995

2653B Trim and Surrounds Mower 87 dB(A) at 3150 r/min engine speed

Vibration Measurements

Hand/Arm Measured Per ISO5349

2653B Trim and Surrounds Mower with reels 0.74 m/s2 at 3150 r/min engine speed

NOTE: The value listed above represents the maximum weighted root mean square acceleration.

Whole Body Measured Per ISO 2631/1

2653B Trim and Surrounds Mower with reels 0.80 m/s2

NOTE: The range listed above represents the weighted root means square acceleration to which the whole body is subjected on a representative machine during actual mowing and transport conditions. The acceleration value depends upon the roughness of the ground, the speed at which the tractor is operating and the operator weight and driving habits. Measurements were obtained through actual field data according to STD Procedure in ISO 2631/1.
