The modern combine harvester, also called a combine, is a machine designed to harvest a variety of cultivated seeds. Combine harvesters are one of the most economically important labour-saving inventions, significantly reducing the fraction of the population engaged in agriculture. [ 1 ]
[1] [2] In addition to cutting the small-grain crop, a binder also 'binds' the stems into bundles or sheaves. These sheaves are usually then 'shocked' into A-shaped conical stooks, resembling small tipis, to allow the grain to dry for several days before being picked up and threshed. Withington's original binder used wire to tie the bundles.
The McCormick Farm at Walnut Grove is known as the birthplace of the mechanical reaper, the predecessor to the combine harvester. Cyrus McCormick reportedly designed, built, and tested his reaper all within six weeks at Walnut Grove, although the design may have been an improvement upon the similar device developed by his father and his brother ...
The corn falls out of the threshing drum (and out of the straw walkers) onto the pan, from where it gets onto the sieves. The E 514 has two sieves, the adjustable top sieve (1.85 m 2), and the fixed bottom sieve (1.17 m 2). The cleaning fan that blows over the sieves is driven with a CVT, its speed can be adjusted from 242 to 775 min −1. [1]

The Fortschritt E 516 is a self-propelled combine harvester made by VEB Mähdrescherwerk Boschofswerda/Singwitz. It was developed in the late 1960s and first half of the 1970s, and after extensive testing in 1975, it was put into series production in 1977. [1] In 1983, the E 516's second generation, the Fortschritt E 516 B was introduced.
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 ...
