Fahr combine harvester production previously consisted almost exclusively of one model, namely the small MDL, although an MDS equipped with a 420 cm cutting platform was also in production. Alongside their own models, Fahr-Claeys M 80 and M 103 models were sold in Germany.

In the early 1960s, the construction of an entire family of combine harvesters began. First introduced below the MDL was the M 40, which had a 180 cm cutting platform and a 70 cm wide threshing mechanism. Instead of the MDL's drum conveyor, the feed to the threshing cylinder was done via a transfer auger. The cutting platform's height adjustment was hydraulic. The engine was a VW industrial engine. The engine was positioned on the side of the combine, and the cab was aligned with the centerline of the combine. The ground speed variator was operated by a foot pedal.

In 1963, the MDL was replaced by the M 60, which had a 4-cylinder Deutz diesel engine, a cutting width of 225/255 cm, and an 85 cm wide threshing cylinder. The M 60 had a drum conveyor, and the speed of the unloading auger was continuously adjustable by a variator. The combine in the picture has a larger grain tank than those imported to Finland. In 1964, the M 80 was produced, which had a 270 cm cutting width. The threshing cylinder width was 100 cm.
