In order to directly plant in the no-tillage fields with corn rootstalks, a new type on-tillage planter equipped with cutting and digging corn rootstalk mechanism has been developed. The working performance of the mechanism and single blade resistance torque were been experimented in the soil bin using four different kinds of digging blades and a kind of cutting blade. The testing results showed that the performance of dealing with rootstalks is the best using combination blades of digging blade A4 with cutting blade and the rate of cutting and clearing rootstalks away from the seeding bed is approximately 92% and 96% respectively. The mechanism can creat better condition for seeds that there is nearly no rootstalks in the seeding bed.
