The influence of the cropland length, the work speed and the header width over labour productivity during grain crop harvesting with massive used combines in Bulgaria is researched. The theoretical coefficient of work time utilization and the theoretical labour productivity in 100, 200, 300, 400, 500, 600, 700, 800, 900 и 1000 m during the minimal and maximal combine work speed are calculated. A considerable increase of labour productivity is determined to 400 – 500 m cropland length during the minimal combines work speed and to 600-700 m - during the maximal work speed.
