Fiat 666 (DT) or Landini 7800 (DT)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 666 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 7800 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Landini 7800 (DT) suits loader and hydraulic implement work better on this data: 13% (420 kg / 926 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 Landini 7800 (DT) has 13% more lift (420 kg / 926 lb) than the Fiat 666 (DT) (both lift at the hitch ends, as stated by the source).
- The Landini 7800 (DT) is 44% heavier (1,125 kg / 2,480 lb) than the Fiat 666 (DT) (both unladen weight, as stated by the source).
- The Landini 7800 (DT) has 60% more forward gears (12 gears) than the Fiat 666 (DT) (both forward gears, as stated by the source).
- The Landini 7800 (DT) offers 1000 rpm at the PTO, which the Fiat 666 (DT) does not (as stated by the sources).
- The Landini 7800 (DT) is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts.
- 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 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 666 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 7800 (DT) 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.
