Mechanical and traditional harvesting methods for wheat crop [electronic resource].

Includes references.

Three combine harvesters at different service life (Fortschritt E514 {1} has been serving for 25 years – Class {2} has been serving for 15 years and John Deer {3} has been serving for 2 years) were tested and compared to another mechanical method mower than thresher (one thresher has free knives on the threshing drum {1} and the other has fixed knives on the drum {2}) compared to traditional method (sickle than thresher {1}). The mechanical harvesting methods were done at three different field speeds 1.9, 2.7 and 3.9 km/h for mower and combines. Also, three different moisture contents 12.1, 14.34 and 16.58 % were effected on harvesting, threshing unthreshing, damaged grain and total grain losses for the previous machines.
