Fiat 70-66 F (DT/F) or International Harvester 664?
Which should you choose?
On performance, no comparable figure differs by more than its threshold: on this data the machines are level. On features, the Fiat 70-66 F (DT/F) is ahead on drive.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “the same stated configuration”. Measured figures are compared only with measured, claimed only with claimed, at the same test condition; differences within each figure’s tolerance are not called.

What does this mean in plain words?
- The International Harvester 664 is 39% heavier (758 kg / 1,671 lb) than the Fiat 70-66 F (DT/F) (both unladen weight, as stated by the source).
- The Fiat 70-66 F (DT/F) is available with four-wheel drive; the International Harvester 664 is two-wheel drive (as stated by the sources).
- The Fiat 70-66 F (DT/F) is newer: production began 12 years later. We hold no parts-availability data, so there is no call on parts.
- Even on power at the PTO shaft (both power at the PTO, claimed): the difference is under the 10% threshold for claimed figures, too small to call.
- Even on forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
- Even on top speed (both top speed forward, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on PTO speeds: the same speeds (540, 1000 rpm).
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, three-point lift, maximum permissible mass, a creeper range and PTO independence.
