This bachelor thesis deals with the process of developing and designing a tractor attachement for soil calcification. The attachment was to be carried by tractor and driven by tractor PTO shaft via cardan shaft. The thesis begins with market analysis and the analysis of existing solutions after which a functional stucture of the product was made. Morfological matrix comes next and offers solutions for individual functions of the attachment. Based on that four concepts were made and after evaluating them the best was chosen and was fully elaborated. For the chosen concept 3D model was made, alongside with required calculations and technical documentation. Technical documentation was made in previously agreed scope.
