Deutz-Fahr DX 85 or Fiat 80-66 F (DT/F)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the DX 85 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 80-66 F (DT/F) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Deutz-Fahr DX 85 suits loader and hydraulic implement work better on this data: 29% (830 kg / 1,830 lb) more three-point lift.
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 Deutz-Fahr DX 85 has 29% more lift (830 kg / 1,830 lb) than the Fiat 80-66 F (DT/F) (both lift at the hitch ends, as stated by the source).
- The Deutz-Fahr DX 85 is 119% heavier (2,430 kg / 5,357 lb) than the Fiat 80-66 F (DT/F) (both unladen weight, as stated by the source).
- The Fiat 80-66 F (DT/F) is newer: production began 6 years later. We hold no parts-availability data, so there is no call on parts.
- 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 figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540, 1000 rpm).
- Even on PTO independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the DX 85 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 80-66 F (DT/F) 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, hydraulic flow, maximum permissible mass and a creeper range.
