Aiming at current situation of increasing crop straw output, difficult straw collection and storage and low utilization rate in China's agricultural and animal husbandry production, as well as problems of single function and poor reliability of existing straw coiling and forming machine, a new straw cutting and kneading round baler was designed． Main working parts such as cutting and crushing device, forced feeding device, bale chamber and mesh winding mechanism were designed, and field performance test of machine was carried out． Test results showed that picking width was 2.2 m, bale forming rate was 100%, bale density was 150.8 kg/m3, total loss rate of forage was 1.95%． The machine had reliable working performance and all performance indexes met requirements of national standards． It has important guiding significance for study of straw harvesting with high efficiency and high quality．
