Don-1500 is a Soviet combine harvester. The Rostselmash enterprise has been producing this harvester since 1986 for twenty years. In 2006 Rostselmash switched to newer models (Vector and Acros). At one time Don-1500 was considered the most popular grain harvesting machine. The classic beater threshing scheme, one drum, a straw walker with five keys, a large grain hopper and a powerful engine – these are the distinctive features of this harvester. We also note the fast unloading mechanism and the hardened drive axle. The set includes a header 6, 7 or 8.6 meters long. It is also possible to complete with a chopper, hood, stacker. It was used along with the Niva SK 5.
