The conventional harvesting combines for cereal comprise a shaker aiming (straw walkers) to separate the seeds out of straws coming from the threshing apparatus. The working capacities of the straw walkers and implicitly of harvesting combine depend on the configuration and kinematics regime of shaker. Within the following paper a new theory of straw displacement on the shaker is presented.  This theory is decisive for manufacturing a performing shaker.
