The Experimentation of the TC 5050 New Holland Combine Harvester in Sunflower

Abstract

The work presents the results of laboratory experiments and field studies in sunflower crop harvesting with the New Holland TC 5050 combine harvester. The combine’s harvesting performance was monitored on the level and slope field by determining the work quality indexes and the energetic and operating indexes of the combine studied. When driving on sloping land on the valley -hill direction, grain losses have exceeded the maximum allowable limit, reaching values over 6,5%. When movement was along level curves, the grain loss had registered values close to maximum allowed limit (3%), being therefore the recommended method. Fuel consumption has increased considerably when driving on sloping land compared with driving on the level field. In order to achieve a quality harvesting work, combine harvesters should be adjusted and operated in accordance with land condition and with the agrobiological characteristics of the crops.
