Fiat 450/N (DT) or International Harvester D-436?
Which should you choose?
On performance, every comparable figure that differs favours the International Harvester D-436: hydraulic flow. On features, the Fiat 450/N (DT) is ahead on top speed and drive.
- The International Harvester D-436 suits loader and hydraulic implement work better on this data: 10% (2.2 L/min / 0.6 gpm) more hydraulic flow.
- The Fiat 450/N (DT) suits heavy draft work (ploughing, cultivating) better on this data: four-wheel drive.
- The Fiat 450/N (DT) suits road haulage better on this data: 35% (7.0 km/h / 4.3 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 decides it, question by question?

| Which may carry more ballast and load? | — | — | No figureNo call on maximum permissible mass: no figure on record for the 450/N (DT) and the D-436. |
| Which has the wider choice of gears? | 6 to 9Traktorenlexikon, “Fiat 450-N/450-N DT” | 8Traktorenlexikon, “McCormick D-436 Standard” | EvenEven on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap. |
| Which offers a creeper range? | — | — | No figureNo call on a creeper range: not stated for the 450/N (DT) and the D-436. |
| Which is faster on the road? | 27 km/h (16.8 mph)Traktorenlexikon, “Fiat 450-N/450-N DT” | 20 km/h (12.4 mph)Traktorenlexikon, “McCormick D-436 Standard” | AheadThe Fiat 450/N (DT) has 35% more top speed (7.0 km/h / 4.3 mph) than the International Harvester D-436 (both top speed forward, as stated by the source). |
| Which offers more PTO speeds? | 540 rpmTraktorenlexikon, “Fiat 450-N/450-N DT” | 540 rpmTraktorenlexikon, “McCormick D-436 Standard” | EvenEven on PTO speeds: the same speeds (540 rpm). |
| Which PTO runs independently of the ground drive? | — | independentTraktorenlexikon, “McCormick D-436 Standard” | No figureNo call on PTO independence: not stated for the 450/N (DT). |
| Which drives on both axles? | Two-wheel or four-wheel driveTraktorenlexikon, “Fiat 450-N/450-N DT” | 2WDTraktorenlexikon, “McCormick D-436 Standard” | AheadThe Fiat 450/N (DT) is available with four-wheel drive; the International Harvester D-436 is two-wheel drive (as stated by the sources). |
| Which is newer, and what about parts? | 1970–1977 | 1959–1962 | Ahead (a fact, not an advantage)The Fiat 450/N (DT) is newer: production began 11 years later. We hold no parts-availability data, so there is no call on parts. |
What does this mean in plain words?
- The International Harvester D-436 has 10% more hydraulic flow (2.2 L/min / 0.6 gpm) than the Fiat 450/N (DT) (both pump flow, as stated by the source).
- The Fiat 450/N (DT) has 35% more top speed (7.0 km/h / 4.3 mph) than the International Harvester D-436 (both top speed forward, as stated by the source).
- The Fiat 450/N (DT) is available with four-wheel drive; the International Harvester D-436 is two-wheel drive (as stated by the sources).
- The Fiat 450/N (DT) is newer: production began 11 years later. We hold no parts-availability data, so there is no call on parts.
- Even on power at the PTO shaft (both power at the PTO, claimed): the difference is under the 10% threshold for claimed figures, too small to call.
- 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 speeds: the same speeds (540 rpm).
- 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 independence.
