International Harvester 423 (MC Cormick-International) or ZETOR 5011?
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 ZETOR 5011 is ahead on top speed.
- The ZETOR 5011 suits road haulage better on this data: 25% (5.0 km/h / 3.1 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 ZETOR 5011 is 33% heavier (655 kg / 1,444 lb) than the International Harvester 423 (both unladen weight, as stated by the source).
- The ZETOR 5011 has 25% more top speed (5.0 km/h / 3.1 mph) than the International Harvester 423 (both top speed forward, as stated by the source).
- The ZETOR 5011 is newer: production began 14 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 hydraulic flow (both pump flow, 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).
- Even on PTO independence: every PTO is independent.
- Even on drive: all two-wheel drive.
- 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.
