In introductory part of this bachelor thesis is describes the individual typesetting mechanism, semi-automatic typesetting mechanisms and automatic typesetting mechanisms, for which I selected one of the most suitable typesetting mechanism for my use. In the design part, the design od individual parts of the planting machine is elaborated. In the calculation part there is a control of the chain conveyor, the placement of the require volume of the onion and garlic cloves and the control calculation of the supporting shaft. The following strength analysis of a three-point hitch and frame. The last chapter is the conclusion, which contains a summary of the bachelor thesis.
