The German MF branch’s 630 was a significant machine in the mechanization of agriculture in Finland as well; by the late 1950s, over half of the threshers in Finland were 630s and their bigger brothers. Introduced in 1954, the 630 initially came to Finland under the Massey-Harris brand. Its engine was a VW industrial engine. The 1960s models also offered a 1.8-liter diesel. The bigger brother of the 630 was the 685, the predecessor of the 87, which had a 4.5-liter Perkins diesel.

Hydraulic height adjustment for the cutter bar and reel was an optional extra on the 630. The reel’s rotational speed was steplessly adjustable by changing the position of the drive levers within a slot. The angle of the reel’s tines could be adjusted. Feeding from the cutter bar to the threshing drum was done via transfer drums. The threshing and separation surface area of the 630 was quite modest. Driving speed could be steplessly adjusted with a variator.

A rotary sieve sorter was standard equipment, aimed at separating weed seeds. A 7-hectoliter grain tank was available as an optional extra for the 630, while the 685 had a 15-hectoliter tank as an optional extra.

In the original 630, the engine output was 23 hp and the cutting width was 160 cm. In 1956, the model received the letter S suffix. Power increased to 29 horsepower and the cutting width to 175 cm. This added just over 200 kg in weight. The 685 sometimes also used the S letter in its model designation, but in that case, the difference from the non-S version was only in the marking.

According to the numbering system inherited from Massey-Harris, models starting with 6 were German, those starting with 7 were British, and those starting with 8 were French. Thus, the model 830 was produced in France, differing from the corresponding German model mainly in its engines. Offered were Peugeot’s 1.5-liter gasoline engine (27.5 hp) and a 2-cylinder 1.0-liter Bernard diesel (25.5 hp). The British 735, on the other hand, used a BMC 1.5-liter gasoline/petrol engine.
