Info
The largest model in the modernist designed and enclosed series introduced in 1964 was the MD 630 (MD = Mähdrescher = combine harvester). Later, the series was supplemented with the models MD 530 and MD 730, the latter being the first 5-rotor model. The two largest models originally had Perkins engines, although in the final phase the engine in the 630 was replaced with JD's own product. The 530 was found to be the most efficient combine harvester in its class in the Vakola group test at the time. The threshing machine width and the diameter of the threshing drum in this series have remained the same even into the 2000s.

The data has been collected primarily from brochures. In some cases, sources contain conflicting information. In such cases, we have attempted to select the most reliable information.
There is particularly significant variation in speed data, which varies depending on factors such as tire size. For tires, only the size most commonly used in Finland is listed.
Other changes during the model history have been addressed in the text section. For the front axle lock, the Finnish term "hammaslukko" (gear lock) is used for all 100% locks.
