Fiat 1880 (DT) or John Deere 4640 (A)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 1880 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4640 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Fiat 1880 (DT) suits road haulage better on this data: 19% (1,570 kg / 3,461 lb) more maximum permissible mass.
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 John Deere 4640 (A) has 126% more hydraulic flow (70.2 L/min / 18.5 gpm) than the Fiat 1880 (DT) (both pump flow, as stated by the source).

- The Fiat 1880 (DT) offers 540 rpm at the PTO, which the John Deere 4640 (A) does not (as stated by the sources).
- 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 PTO independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- Not comparable on power at the PTO shaft: the 1880 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4640 (A) 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 and a creeper range.
