In 1979, Hürlimann celebrated its 50th anniversary, and the event was marked by renewing the entire model range and changing the products' color from red to light green. The engines were also an entirely new series. Development of the model range had begun before the Swiss factory was acquired by Same in 1977, so there were still few technical similarities. However, the front axles of the four-wheel-drive models were made by Same.

The H-6130 and H-6160 were equipped with a 6.8-liter engine, which was later also used in Lamborghini and Same’s largest models. The H-6160’s engine was turbocharged. Instead of the four basic gears found in smaller models, the transmission had only three basic gears, with a total of 12+4 gears.

The lifting capacity of the H-6130 was the same 4 tons as in the mid-range models. The output of the standard hydraulics was not specified, but a more powerful 65-liter pump was available as an option. Considering these figures, it is surprising that the tractor’s weight is one ton heavier than the 115-horsepower model. The H-6160 came standard with a more powerful pump and a 6-ton lifting capacity.

The series also included the H-6200 with a 7.5-liter engine (200 hp), but only two units were produced. It had a 36+12 transmission and a lifting capacity of 7,500 kg. Sales of Hürlimann tractors outside their home country were hindered by higher prices compared to competing brands. These models were indeed the last tractors manufactured in Switzerland.
