Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 63(2): 383–386.Designed in Bulgaria for the needs of organic, environmentally-friendly and conventional agriculture, the universal composting machine requires to be attached to the front of tractors when being used in aggregates. However, it is rare to fi nd such tractors. What is more, tractors with front – sha power take almost do not exist. For this reason the universal composting machine is rather limited from a technological point of view despite its capacity and this made it necessary to improve it through the development and testing of a hydraulic power drive system. The purpose of the present study is to discuss the technical and technological changes in the design of the composting machine which have resulted in increased performance under conditions of sustainable agriculture in Bulgaria. Keywords: composting, universal composting machine, technological schemes, hydraulic power drive system
