The investigation has been done in 2005–2006 in experimental field of IAgEng LUA. When harvesting the peas variety ‘Eiffel’ yield by combine SR 500 with the stripper header and without it. The biometrical peas indexes and technological characteristics were examined. The agrotechnical–energetic parameters, the costs of harvesting one hectare, the actual fuel consumption, total energy of peas yield and coefficient of the energetic efficiency were determined while stripping–threshing and cutting–threshing (conventional technology of peas harvesting) the crop of peas. Losses of stripping, threshing – separating and total peas grain losses when using combine – harvester SR 500 and an experimental stripper were established in relation with combine – harvester’s working speed. Rational rate of stripping drum revolution for peas is 480–530 min-1. During comparative research dependences of cutting, threshing – separation and total grain losses on combine driving speed using traditional technology and combine SR 500 were established. Compared with traditional peas harvesting technology, the output of a combine SR 500 in the stripping – threshing technology increases twice, fuel consumption decreases round 30 %, harvesting costs decline 24 EUR per hectare.
