Oliver 1555-1955 / Minneapolis-Moline G550-G940

Here is the translation of the text to English:

The 55-series Olivers from 1555 to 1855 were based on the earlier 50-series models with very minor changes. The 1955 was a new, more powerful version of the 1855. The larger Olivers, on the other hand, were Minneapolis-Moline tractors painted green. The engines were the same 6-cylinder ones as before, except that the 1855's diesel engine was replaced with a smaller turbocharged one. The 1655 and 1755 had more power than their predecessors. The unsynchronized 6+2-speed transmission of the 1555 could be equipped with a hydraulic quick-shift. The larger models were offered with a three-speed quick-shift. The PTO speed could be changed to 1000 rpm by swapping the shaft. From the 1755 onwards, the brakes were hydraulic.

The 1555 model options were Row Crop, Row Crop Utility, and Wheatland/Riceland. The larger models were available as Row Crop and 4WD versions; the 1655 was also available in Wheatland/Riceland versions. The four-wheel drives still had a very short wheelbase. All models could now be optionally equipped with an enclosed cab and auxiliary fuel tanks on the rear fenders.

In the Minneapolis-Moline lineup, these tractors were introduced as models G550, G750, G850, and G940.
