In the present paper, the mechanism of a mowing machine is analysed by the tensor-matrix procedure as applied in the kinematic analysis of the spatial mechanisms, in and [2]. All position tensors, velocity tensors, and acceleration tensors of the mechanism members $I_v$ with respect to the mechanism members $I_{v-1}$, with which they form kinematic pairs, are determined. For concrete mechanism parameters, graphs of the coordinates $\lambda,\delta$ and $r$, are plotted as functions of the angle a by applying the methods of the numerical mathematics.
