About the Fiat/Hesston 55-66

The first Fiat/Hesston 55-66 Tractors went out of the factory gates in 1985 and they kept building them until 1989. Sold initially at a price of $17,400 (1990), the Fiat/Hesston 55-66 Tractor had a few price variations, so if you got it for less, you found a great deal! We have all the parts you need for your Fiat/Hesston 55-66 Tractor to keep it running. Make sure you have access to your tractor serial number, because there is a chance that the Fiat/Hesston 55-66 parts you need depend on that serial number. Some Fiat/Hesston 55-66 Tractors have a 4x2 2WD chassis, but there are also some with a 4x4 MFWD 4WD (55-66DT) chassis, all equipped with hydrostatic power steering. They also have mechanical wet disc brakes. The type I/II 3-point hitch is very reliable, capable to lift 3,920 lbs [1778 kg]. It is also worth noting that the independent rear PTO runs at 540/ground rpms.
