The 1990's would come to represent the decade of renewal and change for Fiatagri, as well as the end and beginning of an era.

In 1990, the early afternoon, Fiatagri's new Winner-series was revealed to the global dealership network at the Paris Conference Center, showing a new direction for Fiatagri's design and technology.
This was followed by a historic display down the Champs Elysées, where two kilometers of pavement had been turned into a field ready for harvest. Laverda harvesters worked their way down Champs Elysées, while Fiat tractors pulled the grain carts, followed by Fiat tractors with Hesston ballers.
All in the center of Paris! Nothing like this had been witnessed before, and Fiatagri received huge and positive media coverage.

The year after in 1991, the Fiat Groups industrial conglomerate "FiatGeotech", of which Fiatagri was a part, purchased Ford-New Holland from the Ford Corporation.
FiatGeotech became "NHGeotech", revealing the strategic decision to merge the Ford and Fiatagri brands, into their new collective brand identity as New Holland.
Though the company would become stronger than ever, many were sad to see the two historic names disappear from the industry. Names that had ment so much to generations of farmers and employees.
But it is worth noting, that there is some poetic beauty to be found in the merger of the two brands,
as it was the design of Fords first mass-produced tractor, the 1917 Fordson model F, that inspired the Fiat engineers to develop their first mass-produced tractor, the 1918 Fiat 702.

In 1992, Fiat introduced the "Black nose" facelifted 66s-series. 
The 66s-series got a domed front grill finished in black, reminiscent of the Winner-series grill design, and got a new synchronized shuttle function for its 12+12 transmission, highlighted by the "S" suffix.
The 66s-series would continue as a standard utility line of tractors only, while the 66-series "Speciali" models and its sister 76-series, were replaced in 1992 by the 86-series.
Based on the improvements the 76-series had made to the 66-series "speciali" models, the 86-series  received the new "Black nose" grill, while incorporating new technical features from the 66s-series.
The 86-series "Frutteto", "Vigneto" and "Low Profile" were replaced by the New Holland TNF (1997), TNV, and TNN (2000).

The 66-series based 56-series continued production along with the 66s-series as the 56s-series.

All Fiatagri products sold internationally and domestically under the Fiatagri brand, with the individual manufacturers brand only located on the sides of each machine. In the case of Fiatagri's 66s-series tractors, that was the Fiat brand.
The 66s-series however, was unlike it predecessor, never sold in the North American market, as Fiatagri in the 90's decided to focus on the Winner-series models for their Hesston branded tractors.  

The 66s-series kept its stressed chassis design and engines from its predecessor. 

The standard transmission available for the 66s-series was the fully synchronized 12 forward and 4 reverse, with the option of a 20+8 creeper transmission, or a new 12+12 shuttle with synchronized  shuttle function. The four-wheel drive models were capable of 40 km/h.

All four cylinder 66s-models received a new front axle with improved 50 degree steering angle, resulting in a decreased turning radius compared to the 66-series.

Linkage and draft control functions were updated, and the PTO now offered three speeds.

The 56 and 66-series remain in production to this day through New Holland's partnership with Türk Traktör, as a testament to the timeless engineering and appeal of the Fiatagri-era of tractors.
