International Harvester D-440 or Nuffield 3/42 (342)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D-440 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 3/42 (342) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
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 Nuffield 3/42 (342) has 14% more hydraulic flow (3.3 L/min / 0.9 gpm) than the International Harvester D-440 (both pump flow, as stated by the source).
- The International Harvester D-440 has 56% more lift (716 kg / 1,579 lb) than the Nuffield 3/42 (342) (both lift at the hitch ends, as stated by the source).
- The International Harvester D-440 has 60% more forward gears (3 gears) than the Nuffield 3/42 (342) (both forward gears, as stated by the source).
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on top speed (both top speed forward, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on PTO speeds: the same speeds (540 rpm).
- 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-440 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 3/42 (342) 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, maximum permissible mass, a creeper range and PTO independence.
