Hanomag Perfekt 401 (S) or International Harvester D-432?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the Perfekt 401 (S) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D-432 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.

- 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 Perfekt 401 (S) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D-432 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.
