Fiat 640 (DT) or Hürlimann D-150 S?
Which should you choose?
The figures split: the Hürlimann D-150S is ahead on hydraulic flow and PTO speeds; the Fiat 640 (DT) is ahead on three-point lift and drive.
- The Hürlimann D-150S suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
- The Fiat 640 (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 PTO runs independently of the ground drive? | — | — | No figureNo call on PTO independence: not stated for the 640 (DT) and the D-150 S. |
| Which drives on both axles? | Two-wheel or four-wheel driveTraktorenlexikon, “Fiat 640/640 DT” | 2WDTraktorenlexikon, “Hürlimann D 150 S” | AheadThe Fiat 640 (DT) is available with four-wheel drive; the Hürlimann D-150S is two-wheel drive (as stated by the sources). |
| Which is newer, and what about parts? | 1973–1982 | 1966–1971 | Ahead (a fact, not an advantage)The Fiat 640 (DT) is newer: production began 7 years later. We hold no parts-availability data, so there is no call on parts. |
What does this mean in plain words?
- The Hürlimann D-150S has 47% more hydraulic flow (10.2 L/min / 2.7 gpm) than the Fiat 640 (DT) (both pump flow, as stated by the source).
- The Fiat 640 (DT) has 22% more lift (400 kg / 882 lb) than the Hürlimann D-150S (both lift at the hitch ends, as stated by the source).
- The Hürlimann D-150S offers 1000 rpm at the PTO, which the Fiat 640 (DT) does not (as stated by the sources).
- The Fiat 640 (DT) is available with four-wheel drive; the Hürlimann D-150S is two-wheel drive (as stated by the sources).
- The Fiat 640 (DT) is newer: production began 7 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 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.
- 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.
