Economic efficiency of the use of pneumohydroaccumulator systems for protecting working bodies from overloads compared to protection of working bodies with a breaking bolt makes it possible to save money fuel consumption per 1.2 l/ha, capital costs, current repair and maintenance for 13.22 UAH/ha, direct operating costs by 51.04 UAH/ha and total expenses by 61.30 UAH/ha. Annual economic effect – 82755 UAH Branch of application of agricultural engineering and agricultural production. Research results: 1. determined parameters of soil compaction in different soil and climatic zones of Ukraine; 2. a methodology for calculating the pneumohydroaccumulator system for protecting working bodies from overloads has been developed; 3. the terms of reference for the development of design documentation for a prototype chisel tool with a system for protecting working bodies from overloads have been deve Product Description popup.authors popup.nrat_date 2023-03-01 Close
