Browse aftermarket replacement parts for the Fiat 80-66 utility tractor, now supported under the New Holland name.
Use filters or search by OEM part number. Compatibility details are listed on each product page.
Fiat built the 80-66 from 1985 to 1991 as an 80 horsepower utility tractor in its 66 Series, with a four-cylinder Fiat diesel. In North America the same tractor was also sold as the Hesston 80-66. Parts for these Fiat tractors are now sold under the New Holland name.
The later 80-66S, built from 1992 to 1996, is a separate model, so check the model plate before ordering. The 670 uses the same fuel and air filters as the 80-66.
Common replacements include the fuel filter cartridge that replaces OEM 83937061, the primary air filter that replaces OEM 131141, and the air filter that replaces OEM 1909138. Fuel filter cartridges and air filters cover regular service on the 80-66.
