This paper discusses the application of wavelet in the analysis of time series dataobtained from the experiments on the nonlinear dynamics of farm tractors. The experimentalinvestigation was carried out by frequency response test. This was done by running the tractor ontwo types of artificial test tracks made of angle irons over a wide range of travel speeds. In theanalysis, the wavelet used was Coiflets (Coif4) which is among one of the popular wavelets beingused in the area of digital signal processing. By using simple linear models as well asnonlinear/chaotic models, the analysis of the experimental chaotic time series data is possible.
