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 an 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 a deep and earthy 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 four models of the new "medio-bassa" (medium-low) line of 90-series tractors were revealed, with the 55-90, 60-90, 70-90 and 80-90. They replaced the earlier 80-series 580, 680 and 780 models, and presented a host of new features.
The 65-90 would join the lineup in 1987, and the turbocharged 85-90 in 1989.

All Fiatagri products were now 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 essentially new engines, based on the 8035 and 8045 engine-series.
New innovations in fuel delivery and swirl of the air-fuel mixture, insured more power at low revs, and a 30% reduction in fuel consumption compared to the engines predecessor. A remarkable achievement. 

All models were at launch available with a fully synchronized 12 forward and 4 reverse transmission. Options were the 20+8 Overdrive transmission capable of 40 km/h , as well as the later 12+12 Shuttle transmission introduced with the the 65-90 in 1987. 
The 20+12 Creeper added a lower group to the 12+4 transmission, and became an option with the updated 70-90 and 80-90 in 1988.
The 24+12 Hi-Lo added clutchless overdrive to all low/medium/high group forward gears of the 12+12 Shuttle transmission, and was introduced with the 85-90 in 1989.
The 12+12 / 20+12 / 24+12 could be ordered with a low-ratio finale drive, which brought the top speed to 40 km/h. Tractors fitted with this option had a white emblem of a rabbit on the bonnet.

The front axle on the four wheel drive versions of the 65-90, 70-90 and 80-90 models was updated in 1987, resulting in a improved steering angle from 45 to 50 degree, lowring the turning radius by roughly 10%. The new front axle was standard on the 85-90.

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.

The standard Pinninfarina-designed "Comfort" cab from the small 80-series tractors, that the "medio-bassa" 90-series followed, got a small but important ergonomic update, moving the gearlevers to the right side of the driver, creating an up-to-date cabin with flat floorspace.
This was followed up with the option of a "Supercomfort" cab for the 70-90 and 80-90 in 1985.
The Supercomfort cab, also known as the CL-cab ("Cabina Larga" / Wide cabin), was until then only reserved for the larger five and six-cylinder tractors from Fiat. The cabin was standard on the 85-90.

From 1990, all bodyparts and the cabins structure, were galvanized from the factory.
