In view of the disadvantages of equipment easy to plug of the traditional seeding machine , this paper designs a kind of new Wheat sowing machine for cutting free .Based on the analysis of operation principle of wheat seeder and im-portant parameters selection of wheat sowing machine for cutting free of the main working parts of bidirectional helical cut -ter .The main parts of the Wheat sowing machine for cutting free are established by APDL parameter design language . The results show that the main transmission chain of way can meet the job requirements of Wheat sowing machine for cut -ting free and the main parts can satisfy the intensity and rigidity requirements .
