This bachelor thesis shows the development and design of a tractor mill for corn and cereals. After conducting a market analysis and examination of patents, it was concluded that all tractor mills operate on the same principle but differ in construction. Based on the functional decomposition and the morphological matrix, three concepts were developed. After comparison and evaluation, a concept was selected for which a construction design was then made. A calculation of the critical components was made and then a 3D model and technical documentation were produced.
