This undergraduate thesis presents the development and construction solution of an oscilacation (sickle) tractor mower. The introduction to the thesis describes the key parts for understanding the structure. The next part of the thesis consists of analyzing patents and products on the market. After conducting the market analysis, we make a technical specification, functional decomposition and morphological matrix. With the help of the morphological matrix, concepts are made, evaluating which we decide which concept will be further elaborated and on the basis of it the calculation of components. After the calculations are carried out, 3D models and the necessary technical documentation are made.
