The 1980's and early 1990's represented the golden age of Fiatagri.
A busy periode, with the roll out of a new corporate identity and structure, in the midst of a agricultural recession, the launch of new models and series, ending with the 2.000.000th tractor being produced in 1989, and the NHGeotech conglomerate in 1991.

It started in march of 1983, at the Fieragricola and Sima international fairs in Verona and Paris, when Fiat Trattori S.P.A went ahead and introduced their new identity. - Fiatagri.
This not only marked the beginning of a new corporate structure, with Hesston and Laverda becoming an integrated part of the company's "full-line" of agricultural machinery and equipment, but also the beginning of a legend within the agricultural community.

The new color scheme of Fiatagri was inspired by Italian "terracotta" red clay ceramics.
Fiat decided to use red clay as their theme, as red clay in its natural state, depending on conditions, could appear like the orange colors of Fiat, or the red colors of Laverda and Hesston. With Fiat having proclaimed its "marriage to the land" before, it seemed fitting, that the final color would be given an earthy-red tone.

The new colors were followed up by an all new logo, into which the designers put a lot of research and creativity. The final result showed, and was a brilliantly thought out stylized leaf, that could also be interpreted as a stylized grain axis, or tracks from the tires of farm machinery.
The logo encompassed everything that Fiatagri stood for, and is still used to this day by Fiatagri's succesor - New Holland.

Fiatagri followed up its launch, by introducing five new series of tractors, with 26 new tractors in total. Given the ongoing recession at the time, this was a powerfull move.

In 1984, the first "Gamma Alta" (High Range) 90-series tractors were officially introduced to the market, with power ranging from 115 to 180 hp. 
The models only retained the outward appearance of the former 80-series. Engines, transmissions and linkages were, in fact, all new. Even so, competitors had started to gain on Fiat, with new electronic solutions and power-shift transmissions. Fiatagri responded to the growing demand for electronic equipment, by spending the next two years developing a new power-shift transmission, and Fiat's first electronic linkage system. These were introduced through the Gamma Alta 90-series in 1986. 
Not long after, Fiatagri introduced a new feature to the series named "Agritronic". Fitted in place of the rev-counter, the digital dashboard computer would, apart from showing engine hours, revolutions and PTO-speed, work together with a doppler radar fitted to the underside of the tractor, to calculate true forward speed, slipping percentage and worked area. 
These new technological innovations from Fiatagri insured, if fully optioned, that the Gamma Alta
90-series tractors were up to date with the latest technical and digital technology in the industry.
In fact the 90-series proved so popular for Fiatagri that, even when the first New Holland tractors came to market, there was still demand for the then old Fiat 90-series tractors.
As a result the 140-90, 160-90 and 180-90, together with the "Bridge" models 100-90 and 110-90, were kept in production and sold as the New Holland "Tradition"-range into the 2000's.

All Fiatagri products were sold internationally and domestically under the Fiatagri brand, with the individual manufacturers brand only, but proudly, located on the sides of each machine.
In the case of Fiatagri's 90-series tractors, that was the Fiat brand. Except for North America, where Fiat tractors were still sold as Hesstons, making for at sometimes awkward situation, with Fiatagri, Hesston and Fiat branding, all on the same tractor. 

The 90-series used the strong and proven stressed chassis design, tracing its roots back to the Golden Ribbon series, but with new engines, based on the 8065 and 8365 engine-series.
The 8065 engine was stroked by 5 mm, and bored out by 1 mm. The result was only little gain in terms of power, but combined with Fiat-Iveco's innovations in fuel delivery and swirl of the air-fuel mixture, this would result in a 30% reduction in fuel consumption compared to the engines predecessor.
The 8365 engine received the same upgrades to its fuel delivery system and combustion chamber.
However, a peculiar "design-flaw" in the upgrades to the 8365 engines fuel delivery system ment,
that it became very easy to gain more power from the engines. Allegedly more so on the 160 than the 180, do to different fuel pumps. 
Some contractors were reported to have tuned their engines to 240hp at the flywheel.
However, over time this didn't go down well with the transmissions, as they were rated at max 200hp...

At launch, all models were avilable with two fully synchronized transmission. 
A 16 forward and 16 reverse shuttle, and a 24 forward and 8 reverse creeper transmission.
The later could be optioned as a powershift transmission from 1986.
In 1987, both the 16+16 and 24+8 transmission got the option of a low-ratio finale drive, which gave a top speed of 40 km/h. Tractors fitted with this option had a white emblem of a rabbit on the bonnet.

Linkage and draft control functions were upgraded and updated for the 90-series, and now featured Fiatagris automatic "Lift-O-matic" raise and lowering system. And "Vario speed", which enabled the adjustment of the sensitivity when reacting to the changes in applied draft loads on the lower link.
This was followed up in 1986, with Fiatagri introducing their first electronic linkage control system, developed in collaboration with their electronics supplier Magneti Marelli, and the Physics Faculty of the University of Modena.
