Abstract
Vibration is one of the most important variables to be understood and interpreted in the design and improvement of machines. Tractors have proved to be extremely important for certain tasks such as transport and power supply in the use of agricultural machinery and implements. The vibration that is emitted by the tractors and other mechanical equipment, which propagates in the body of the operator, can cause lesions which can be qualified as occupational diseases. The present work had as objective to measure and analyze the vibration that is transmitted to the operators of agricultural tractors in the field operating conditions. For this, an agricultural tractor was used, with different feedrate speeds coupled to an agricultural brush cutter. The experimental data obtained were analyzed using Blaze software and statistically manipulated. Subsequently, the results were analyzed according to current regulation. The results obtained showed that the vibration levels, in low rotation, are in accordance with what is recommended in the norm for an 8-hour workday. For the tests in high rotation, the vibration levels presented were worrisome, since they do not allow exposure to these levels for 8 hours of work. Therefore, it is recommended to place a new seat, with a higher level of vibration absorption, thus allowing the reduction of occupational vibration to the operator.
