In order to analyze the factors that affect the performance of a furrow opener, the two-dimensional DEM (discrete element method) analyzing models of two types of furrow openers and soil particles were built up. Through changing the CAD models of furrow openers, for each type of furrow openers, the operating processes and resistances in three kinds of soils with different moisture content at three different velocities and depths were analyzed by using the DEM. The performance of the openers was tested at each operating states in lab. The simulation results is in good correlation with the experimental results and the relative errors are within 10%～20%. It can be proved that it’s feasible and favourable to analyze the performances of furrow openers by using the DEM and it provides a new method to study and design furrow openers. 
