Abstract

The objective of this study was to evaluate the smoke opacity and the noise level of a tractor in function of the time of operation. The study was conducted using a tractor without cab. We used a completely randomized design with seven testing times and fi ve replicates for smoke opacity and temperature of the engine oil. For the noise level a factorial was used, composed of seven testing times and two sampling positions (at the location of the operator and at the exhaust) at idle and maximum engine speeds. The values of smoke opacity varied according in the time of testing, showing higher values after 12 hours. The smoke opacity values were below the limit established by the Brazilian standards of 2.5 m-1. Environments with lower temperatures and humidity resulted in lower opacity values. Noise level was infl uenced by the time of testing and was higher at the exhaust location than that of the operator. The noise levels were above the limits established by the Brazilian standard for eight hours of work without hearing protection.
