Info

The German IH middle class, the so-called B-series, consisted of models 554-844 from 1974 onwards. In the earlier model range (553-824), sales were concentrated on the smallest models, but in the new series the favorite became the 844-S (80 hp).

In the new series, the synchronized 8+4 transmission also featured a mechanical reduction gear for lower speeds. The gear selectors were located on the dashboard under the steering wheel. The lifting capacity had been significantly increased compared to before. The production program included versions with both dry and oil-immersed disc brakes. In Finland, the 844 had oil-immersed brakes. The hydraulics featured draft-arm sensing. The cab was initially installed locally (the pictured four-wheel drive model Turla in Finland). In 1976, the factory-installed Comfort 2000 was introduced (see 946-1246). At the same time, the gear pattern was changed and the reduction gear became synchronized.

In Finland, the 844 was initially sold, and in 1976 it was replaced by the 844-S. The wheelbase of the 844 was 27 cm longer than the previous 824.
