Abstract: The agricultural machinery operation exposes the operator to numerous drawbacks, such as high levels of noise and mechanical vibration. In this context, the objective was to, with the completion of this study was to evaluate the ergonomic parameters in the operator station of a tractor 4x2 TDA, according to the tractor speed, internal pressure and the type of construction of the tires. For each type of tire construction was assembled an experiment in which we evaluated the influence of internal pressures of the front and rear tires and the speed of mechanical assembly. Noise levels were higher than those established by the NR-15, for a journey of 8 hours of work. The increased internal pressure of the tire implies increasing vibration levels in the two senses. In both the radial and bias tires, the larger amplitudes of vibration in the longitudinal direction was between 0 and 2.0 Hz. Already, the vibrations in the vertical direction showed higher amplitudes range between 1.5 and 4.0 Hz.
