In 1989 the injection was electronically regulated and new ECUs added to control the most important functions of the traction components and differentials. In 1990 115 HP (H6115) and 135 HP (H6135) models were released. 1991 was the year the MASTER range was launched, high power tractors fitted with the innovative “Electronic Power Shift” transmissions. Thanks to the PRINCE range of smaller tractors, in 1993 Hürlimann entered a new market segment: small-scale farming and agriculture.

At the end of the 1970s, the heirs of Hans Hürlimann made a proposal to Vittorio Carozza – who had been at the helm of SAME for a few years, who replaced Francesco Cassani – to take over the company. The deal was concluded quickly to the satisfaction of both parties: in 1979 SAME officially became“SAME Lamborghini Hürlimann” (SLH), the number two Italian manufacturer and ranking among the top places on the worldwide market, with a complete and differentiated range of models. Production began on the series “H” models: a new range of tractors with 60 to 160 hp engines (H-1103, H-1104 and H-1106) aimed for the European market. Five years later (1984) another breakthrough: a new range of machines with a 54 - 165 hp was introduced, with innovative features, new styling and original cab. The H1104, H1105 and H1106 engines, fitted on the early models, were later replaced with 1000 Series engines cooled by water.

Ahead of the times and probably too early for the market, the T14000 was manufactured. A 150 HP tractor with continuously variable transmission.

The first tractor with a turbo engine was launched on the market to meet the requests of customers who required higher power and lower consumption.

New synchronised mechanical transmissions were introduced with 6 gears and 3 ranges combined with the assembly of a ZF front axle to obtain a four wheel drive.

A modern manufacturer and skilful salesperson, Hans Hürllimann grasped all of the benefits of a production approach aimed at quality rather than quantity: every year the factory manufactured a limited number of machines, which Swiss (and not only) farmers considered among the best tractors on the market. In 1966 Hürlimann was one of the first tractor factories to build high capacity models, manufacturing a 95 hp model with a 4 cylinder engine (540/1000 rpm) designed and manufactured by the company and introduced the first hydraulically driven PTO (540/1000 rpm).

The first D 800 was released from the Hurlimann plants, specifically designed for the foreign market

The famous D90 was released from the Wil plants in 1959, remembered as the best known model of the brand. The engine, clutch, gearbox gears, axle and hydraulics were all built and assembled by Hürlimann.

The company expanded its factory after the war, consolidated its position on the market and began exporting. Hürlimann introduced the D600 tractor (70HP) during the 1950s, which was especially popular in Argentina (a significant portion of the production was earmarked for South America). In 1950 Hürlimann patented a motorised harrow with excellent performance capacities: the documented production was 6,162 m2 harrowing per hour .

In 1940 Switzerland also had to deal with the effects of World War II and Hürlimann modified its production: diesel tractors were changed to operate with coal gas for fuel. During the same period new rear wheels with pressure spring suspension systems and without inflatable tyres were tested.
