The main aim of this diploma thesis is to determine the radius of rotation of selected tractors (Zetor Forterra 140 HSX, Zetor Proxima 120 Power and Zetor 7745 Turbo) on three different types of surfaces using different speeds. The literary part deals briefly with the importance and historical development of tractors, the basic knowledge of traction theory, the problems of forces acting on the rolling wheel, and last but not least the construction of the tractor parts. The practical part is mainly focused on determining the radii of rotation of individual tractors on three specified types of surfaces using the three given speeds. The discussion is mainly focused on comparing the radii of rotation meeting ČSN 30 0552 with the radii given by the tractor manufacturer.
