Only the smallest model, the 520, of the large MF combine harvesters was imported to Finland. The largest model sold in Europe was the 760, equipped with a 152 cm wide threshing unit. In these combines, the engine was placed on the side of the cab above the reel chamber.

The MF 525 and 625 were already introduced in 1964. In terms of appearance, they were much more modern than the smaller 510 of the same period. The engines were Perkins' new A6.354 and A6.372 models. The threshing drums were 11 inches wider than the threshing drum. Behind the threshing drums was a rotating after-separator that returned grains that passed over the threshing drums back to them using an elevator. The 625 had a distinctive three-tiered sieve structure.

In 1971, the modernized 520 was introduced as the successor to the 510, with significantly increased threshing drums and sieves compared to its predecessor. The 520 was actually the same combine as the 525 but without the after-separator and a few other features. The 525 was not imported to Finland, and the 520 model here came standard with features such as an adjustable grain sieve and automatic height adjustment for the cutter bar. The problem with the 520 in Finnish conditions was clogging of the saddle-shaped upright spiral in the grain tank. The long cutter bar was introduced to the 520 with the Super II model in 1977.
