Layout of belts and chains combine CLAAS Dominator 56
Production of harvest combines in the territory of German democratic republic (East Germany) began with technical assistance of the Soviet Union. The S-4 model (Stalinets) was taken for a basis. A manufacturing started in 1948. The combine was equipped with a 4-meter heder and 6-cylinder petrol engine. Then there was no variator on combines. In 1953 the combine received the diesel engine and was renamed into E-171. The E-173 model with a 3-meter heder was made at the same time. The grain bunker almost was absent, and the volume for straw had a barrel tank form.
In 1968 E175 with 3m header and E176 with 3,6m header models were launched based on USSR license SK-3 "Stalinets". Last of which was sent exclusively for export . Combines had grain tanks respectively 1,3 and 1,7 cubic meters. Other combines of a series – E174 and E177 were equipped with hydraulics which served for management of a heder. Here the regulated speed of rotation of a drum was applied It was in limits of 385-1250 rpm. All models had the unified engine and transmission. The most widespread model was the E 175 combine. It was made till 1975.
