International Harvester 423 (MC Cormick-International) or VALMET 500?
Which should you choose?
On performance, no comparable figure differs by more than its threshold: on this data the machines are level. On features, the International Harvester 423 is ahead on forward gears; the VALMET 500 is ahead on top speed.
- The VALMET 500 suits road haulage better on this data: 50% (10.0 km/h / 6.2 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 International Harvester 423 has 33% more forward gears (2 gears) than the VALMET 500 (both forward gears, as stated by the source).
- The VALMET 500 has 50% more top speed (10.0 km/h / 6.2 mph) than the International Harvester 423 (both top speed forward, as stated by the source).
- 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 hydraulic flow (both pump flow, as stated by the source): the difference is under the 10% threshold, 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 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.
- 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.
