2.10 Noise development data
The work place related emission value (sound pressure level) is 74 dB(A), measured in operating
condition with the cabin closed at the ear of the tractor driver.
Measuring instrument: OPTAC SLM 5.
The sound pressure level mainly depends on the vehicle used.
2.11 Necessary tractor equipment
The tractor must meet the specified power requirements and should be fitted with all necessary
electric, hydraulic and brake connections, to be able to work with the machine.
