Considering the soil of in mid-lower Yangtze River is sticky and the amount of straw is large, the furrow should be ditched while rapeseed is planting, which leads the power consumption of traditional tillage is large. Compared with the traditional plow, driven disc plows are not easy to be blocked and traction resistance is small. The design of symmetrical type driven disc plows combined tillage machine for rice-rapeseed rotation area was carried out. According to dynamics and kinematic analysis of driven type disc plows, its main structure and technical parameters were analyzed and determined. Based on the principle of plow forming and soil extrusion, the surface of front ditch plow was designed, and it was determined that when the width of ditching area was 350mm, the quality of furrow and seedbed can be ensured. The tillage depth stability experiments results indicated that actual working depth of the machine was consistent with the control depth, and tillage stability coefficients were more than 90%. The seedbed quality experiments results showed that the depth and width of furrows which was ditched by ditching system were 241.6~293.5mm and 328.6~370.8mm, respectively. The soil squeezed by combined ship type opener can effectively filled the furrows which was formed by driven disc plows, the actual landfill rate of furrows was more than 87.67%. The seedbed roughness was 22.45~26.70mm，soil crushing rate was 60.14%~68.37%. The orthogonal test indicated that the optimum operation condition was the tillage depth was 180mm, the speed of machine was 3.5km/h, and operating speed of driven disc plows was 160r/min. Under this condition, the power consumption was 24.37kW, straw coverage rate was 92.78%, soil crushing rate was 66.74%, seedbed roughness was 24.18mm, and landfill rate was 92.3%. The experiment results showed that the quality of symmetrical type driven disc plows combined tillage machine satisfied the actual production requirements of rapeseed planting. The research conclusion had great theoretical value and practical significance to the design of machine which worked for planting rapeseed.
