Micro- and macro-damages of seeds appear during the harvest of pulse crops with a combine harvester. An examining stand was built in which spinning, at the velocity of a threshing drum, of the percussion element struck individually fed horse-bean and lupin seeds. Four velocities of the percussive elements (18,8 - 28,2 m/s) and 4 levels of seed humidity (15 - 24%) were used. Size and type of damages which occured during the investigations were examined and then energy and germination capacity of damaged seeds were determined. It was found out that humidity of seeds has the great influence on the capacity and energy of germination of horse-bean and lupine seeds and next it is the value of loading, expressed by the velocity of the percussive element. Multiple regression equations describe the found out dependence.
