Fahr D 400 C or Fiat 45-R?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D 400 C has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 45-R has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Fahr D 400 C suits road haulage better on this data: 30% (4.8 km/h / 3.0 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 Fahr D 400 C is 12% heavier (270 kg / 595 lb) than the Fiat 45-R (both unladen weight, as stated by the source).
- The Fahr D 400 C has 30% more top speed (4.8 km/h / 3.0 mph) than the Fiat 45-R (both top speed forward, as stated by the source).
- The Fiat 45-R has an independent PTO; the Fahr D 400 C’s is dependent (stops with the clutch).
- Even on hydraulic flow (both pump flow, 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 drive: all two-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 D 400 C has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 45-R 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, three-point lift, maximum permissible mass, a creeper range and PTO speeds.
