This research has the main objective to analyze the magnitude of efficient accelerations on the seat-operator interface, using three adjustment knob positions, two scarification depths, two displacement speeds and three different ballast settings. The experiment was held at the Federal University of Santa Maria through a subdivided portion experimental design, with four repetitions and 144 experimental units. A agricultural tractor was used with 63kW of power on the engine (63kW) attached to the chisel plow. The information was recorded by the accelerometers that were installed on the seat-operator interface. It was concluded that the magnitude of efficient accelerations obtained on the seat-operator interface in all the 36 individual tests stayed above the comfort limit on the frequency of 1 to 80Hz, established by the standard (International Organization for Standardization 2631-1: 1997) for daily eight hour exposure.
