Abstract:
The ergonomic aspects of power tiller are of great importance as the operator of a power tiller has to endure various environment and stress. Excessive noise level is the important shortcomings in ergonomic aspects of power tiller. The sound pressure level meter was used for measurement of sound pressure or noise level of power tiller at field condition. The parameters are selected for the field evaluation of power tiller with different forward speeds, rotary speeds and type of blades like 1.8, 2.1 and 2.4 km h^-1, 220, 260 and 300 rpm and C and J type of blades, respectively. The results found that maximum noise at bystanders position and operators ears position were 88.40 dB(A) and 97.00 dB(A) was recorded at 300 rpm of rotary speed for C type of blade.
