Hesston – other models: the collective page of Fiat-Hesston tractors outside the named ranges, from the 45-66 DT to the 1880 DT and the orchard type 60-66 DT orchard, 29 to 121 kW, Fiat diesel engines
This page gathers the Hesston tractors the register could not assign to a named range. Hesston Corporation of Kansas was originally a maker of hay and harvesting equipment and entered the tractor market in the 1970s through a cooperation with Fiat Trattori: the tractors sold as Fiat-Hesston were technically largely identical to the Italian Fiat models, renamed for the North American market. The type logic follows Fiat's system: the first number roughly gives the hp class, the second number after the hyphen the range generation – for instance the 66 series in the 45-66, 60-66 and 80-66 – DT stands for Dual Traction, meaning four-wheel drive, and the suffix orchard or High-Clearance marks narrow or raised-clearance versions for orchards and row crops. After Fiat's farm-equipment division passed through later corporate restructuring, the Hesston heritage also moved into the AGCO group in the 1990s.

The register lists here 14 versions with 29 to 121 kW, or 39 to 162 hp, all with Fiat diesel engines.
The Fiat-Hesston cooperation exemplified the transatlantic ties of the tractor industry in the 1970s and 1980s, in which European makers sought access to the North American market through partner brands, before takeovers and mergers reordered the brand landscape.
On used examples, the condition of the Fiat diesel engine and the injection pump, the tightness of hydraulics and lift, the state of the four-wheel drive on the DT versions, and on the orchard and High-Clearance variants the state of stub axles and steering count; spares run through the Fiat network, today CNH.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
