Layout of belts and chains combine Dominator 48
Year of the 1989th became for Germany year of falling of the Berlin wall and the association GDR and West Germany to the uniform state. More than 90% of production of FORTSCHRITT were exported to SEV countries (socialist countries, in the main USSR). After disorder of the Berlin wall and association of currencies of uniform Germany the plant lost the sales market and naturally experienced financial difficulties.
At the same time the combine had new opportunities on a complete set of the products better "western" spare parts. As the result, to the E 517 combine came to change E 518, differing a new komplekttion: 11-liter, V6 MERCEDES engine with a power of 222 h.p. and BOSCH hydraulics.
After privatization of the former state enterprise in 1990 the new owner of Fortschritt became MDW Mähdrescherwerke GmbH company (Fortschritt Mähdrescherwerk Bischofswerda/Singwitz). New firm color became dark blue. Line of production made already familiar to E514 and E524, and also their modification of E 514 S which is constructed on the E521 and E514 elements. t was more powerful combine, with a new cabin, the big grain bunker and Schumacher sharp system.
In 1993 the E500 series was finished by the largest E527 combine us a leader. It was equipped with new engines: Perkins, Volvo Penta or MB OM441. As well as in the previous E514 and E521 models the transmission basis here was constructed on the basis of hydraulics. A complete set for similar models strongly differed. For-example, E 525 was nearly 70% more expensive, than similar, but slightly smaller model E521. Despite a modernized number of combines of the MDW Fortschritt series their production fell with 4500 to 300 per a year.
