e176

The S-4 «Stalinets» (Russian: С-4 «Сталинец»), is a self-propelled combine harvester, made by several different combine harvester plants in the former Soviet Union, from 1947 until 1955. In 1955, the modernised variant, called the S-4M, was introduced; it was put out of production in 1958. In total, 29,582 units were built. In former East Germany, the S-4 combine was built under licence by the IFA as the Fortschritt E 170 series (E 171, E 173, E 174, E 175, E 176, and E 177), from 1954 until 1967. Unlike the original S-4, which is powered by an otto engine, the Fortschritt E 170 series combines were all powered by a diesel engine, and some of them came with a chaff waggon rather than a straw waggon.The S-4 is the first self-propelled Soviet combine harvester, it succeeded the S-1, one of the early 1930s Soviet pulled combine harvesters. There is no evidence of existing S-2 and S-3 models, it is therefore likely that they were both cancelled during the development phase. When the S-4 was introduced in 1947, it was first built at the Krasnoyarsk combine harvester plant. The second generation of self-propelled Soviet combine harvesters, the SK-3, was introduced in 1958. In East Germany, the successor to the Fortschritt E 170 series was the Fortschritt E 512, an entirely new combine harvester, designed from scratch. A transition model, called the Fortschritt E 510, which was still based upon the 1947 S-4, had been developed, but was eventually not put into series production.
