Fortschritt E 510

The Fortschritt E 510 was a self-propelled combine harvester, developed in the early 1960s by the East-German Fortschritt combine. It was a heavy modification of its predecessor, the Fortschritt E 170 series. Several E 510 combines were made for testing purposes; however, the tests which were conducted in the 1963 harvesting season showed, that the E 510 was no improvement over the E 170 series. Despite having developed the E 510 to a point where it was ready to go into series production, the E 510's series production never commenced, and the E 510 was cancelled. Instead, Fortschritt developed a completely new combine harvester, the Fortschritt E 512.

Development

The E 170 series combines, which had been in production since 1954, proved to not be well-suited for the growing East-German Agricultural Production Cooperatives, because of their high corn loss, poor ergonomics, and aging design;[1] in addition to that, the E 170 series combines had a small header, a small corn tank, and no continuously variable transmission (CVT). Therefore, Fortschritt sought to replace the aging E 170 series with a new, more efficient model. Development began in 1962. The new model – designated the E 510 – was basically a heavy modification of the ongoing E 170 series. The E 510 had a header that was approximately 200 mm wider, a bigger corn tank with an improved unloading mechanism, a three-speed gearbox with an additional CVT, and the 44 kW engine from the E 175. It was considered upgrading the engine even further to 55 kW.[2] After a series of tests conducted in the 1963 harvesting season, where the E 510 had to compete against several combine harvesters from Western countries, it became obvious that it was not a significant improvement over the E 170 series. Therefore, it was decided in February 1964, not to put the E 510 into series production. From 1964 to 1968, a new combine harvester was developed, the Fortschritt E 512. It was later put into series production instead of the E 510. Only a few pre-production units of the E 510 were made.[3]
