Fiat 540 (DT) or Fiat 55-66 V/F (DT-V/F)?
Which should you choose?
On performance, every comparable figure that differs favours the Fiat 55-66 V/F (DT-V/F): three-point lift. It is also ahead on top speed and PTO speeds.
- The Fiat 55-66 V/F (DT-V/F) suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
- The Fiat 55-66 V/F (DT-V/F) suits loader and hydraulic implement work better on this data: 60% (980 kg / 2,161 lb) more three-point lift.
- The Fiat 55-66 V/F (DT-V/F) suits road haulage better on this data: 20% (5.0 km/h / 3.1 mph) more top speed.
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 Fiat 55-66 V/F (DT-V/F) has 60% more lift (980 kg / 2,161 lb) than the Fiat 540 (DT) (both lift at the hitch ends, as stated by the source).
- The Fiat 540 (DT) is 21% heavier (325 kg / 717 lb) than the Fiat 55-66 V/F (DT-V/F) (both unladen weight, as stated by the source).
- The Fiat 55-66 V/F (DT-V/F) has 20% more top speed (5.0 km/h / 3.1 mph) than the Fiat 540 (DT) (both top speed forward, as stated by the source).
- The Fiat 55-66 V/F (DT-V/F) offers 1000 rpm at the PTO, which the Fiat 540 (DT) does not (as stated by the sources).
- The Fiat 55-66 V/F (DT-V/F) 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 forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, maximum permissible mass and a creeper range.
