Agro cross-country ability of combine harvesters with driving wheels equipped with different tires

Introduction. An important area of agricultural industry development is improving the operating efficiency of wheeled mobile agricultural machinery. The real situation analyzing has shown the presence of a number of difficulties associated with many factors including high agricultural machine weight, which, along with increased performance, leads to the over-compaction of all soil layers that results in reduced yields of cultivated crops and increased energy consumption during subsequent processing. Despite the significant successes of domestic and foreign researchers and research teams in this area, these difficulties impede the development of an optimal solution to the problem. Therefore, the relevance of the materials presented in the work is beyond doubt. Aim of the Study. The study is aimed at assessing of agro cross-country ability of the fifthgeneration domestic combine harvesters when harvesting winter wheat.
