Fiat 415 (DT) or Fiat 450 (DT)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 415 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 450 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Fiat 450 (DT) suits loader and hydraulic implement work better on this data: 21% (3.8 L/min / 1.0 gpm) more hydraulic flow.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “similar machines”. 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 450 (DT) has 21% more hydraulic flow (3.8 L/min / 1.0 gpm) than the Fiat 415 (DT) (both pump flow, as stated by the source).
- The Fiat 450 (DT) has an independent PTO; the Fiat 415 (DT)’s is dependent (stops with the clutch).
- The Fiat 450 (DT) is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts.
- 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 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 rpm).
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the 415 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 450 (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, three-point lift, maximum permissible mass and a creeper range.
