Fiat 650 (DT) or Renault 90 S?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 650 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 90 S has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Renault 90 S suits loader and hydraulic implement work better on this data: 11% (235 kg / 518 lb) more three-point lift.
- The Fiat 650 (DT) suits heavy draft work (ploughing, cultivating) better on this data: 60% (1,075 kg / 2,370 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.

What does this mean in plain words?
- The Renault 90 S has 11% more lift (235 kg / 518 lb) than the Fiat 650 (DT) (both lift at the hitch ends, as stated by the source).
- The Fiat 650 (DT) is 60% heavier (1,075 kg / 2,370 lb) than the Renault 90 S (both unladen weight, as stated by the source).
- The Fiat 650 (DT) offers 1000 rpm at the PTO, which the Renault 90 S does not (as stated by the sources).
- The Fiat 650 (DT) is available with four-wheel drive; the Renault 90 S is two-wheel drive (as stated by the sources).
- The Renault 90 S is newer: production began 8 years later. We hold no parts-availability data, so there is no call on parts.
- Even on hydraulic flow (both pump flow, 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 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.
- Not comparable on power at the PTO shaft: the 650 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 90 S has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- 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.
