The lift course of hanging device on wheat no-tillage planter was simulated by using the software of ADAMS. Some important parameters were obtained such as height of the working part relative to ground, the distance between the working part and the rear wheel of tractor, the angle of road pass and the force of hanging point, etc. The key parameters of the hanging device and its best working parameter of hanging device were found out through optimization simulation. Simulation results showed that suspension point had minimum force when variable DV_1 and DV_2 gained corresponding maximum and minimum at scope of structure limit.
