Below the TX series, a smaller 75-horsepower model, the 75-12 TS and 75-14 TS, was introduced in the summer of 1982. In this case, the model number corresponded to the engine power. The tractor's frame was shortened compared to the 4-cylinder TX models, but nearly all of the TX features were retained except for the cabin equipment level. The lifting capacity was also slightly lower. For the year 1984, a new RS model was added to the 75-horsepower class, and the 75-12/14 TS was replaced by the 80-12/14 TX with 78 horsepower. Also new was a mechanical quick-shift option, which increased the number of gears to 24+24.

At the end of 1986, 70-horsepower 77-12/14 TS and 78-horsepower 85-12/14 TS and TX models were introduced. The updates compared to previous models were minor. The biggest change in appearance was the cabin's upper panels changing from white to black. In the short-frame TS and TX models, the tall cabin, inherited from the larger models, looked somewhat oversized.
