Fiat 55-66 (DT) or Renault 55-12 V?

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 55-66 (DT) is ahead on PTO speeds and drive.

  • The Fiat 55-66 (DT) suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
  • The Fiat 55-66 (DT) suits heavy draft work (ploughing, cultivating) better on this data: 22% (405 kg / 893 lb) heavier and 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.

  • Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
  • Not comparable on three-point lift: the 55-66 (DT): lift 610 mm behind the hitch ends, as stated by the source (Traktorenlexikon, “Fiat 55-66/55-66 DT”); the 55-12 V: lift at the hitch ends, as stated by the source (Traktorenlexikon, “Renault 55-12 V R3235”) — not the same quantity, basis and condition.
  • No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, maximum permissible mass, a creeper range and PTO independence.
