Fiat 640 (DT) or Renault 385 / R 77?
Which should you choose?
The figures split: the Renault 385 / R 77 is ahead on hydraulic flow; the Fiat 640 (DT) is ahead on three-point lift and 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 Renault 385 / R 77 has 19% more hydraulic flow (4.2 L/min / 1.1 gpm) than the Fiat 640 (DT) (both pump flow, as stated by the source).
- The Fiat 640 (DT) has 50% more lift (750 kg / 1,653 lb) than the Renault 385 / R 77 (both lift at the hitch ends, as stated by the source).
- The Renault 385 / R 77 is 10% heavier (240 kg / 529 lb) than the Fiat 640 (DT) (both unladen weight, as stated by the source).
- The Fiat 640 (DT) is available with four-wheel drive; the Renault 385 / R 77 is two-wheel drive (as stated by the sources).
- The Fiat 640 (DT) is newer: production began 10 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 figures vary by configuration and the ranges overlap.
- 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 rpm).
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, a creeper range and PTO independence.
