Fiat 70-66 (DT) 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 (DT) is ahead on drive.

  • The Fiat 70-66 (DT) suits heavy draft work (ploughing, cultivating) better on this data: four-wheel 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.

Which is newer, and what about parts?1984–19911972–1973Ahead (a fact, not an advantage)The Fiat 70-66 (DT) is newer: production began 12 years later. We hold no parts-availability data, so there is no call on parts.

What does this mean in plain words?

  • The Fiat 70-66 (DT) is available with four-wheel drive; the International Harvester 664 is two-wheel drive (as stated by the sources).
  • The Fiat 70-66 (DT) 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 weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, 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 figures vary by configuration and the ranges overlap.
  • 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.
