Fahr D 181 or International Harvester Super FC-C?
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 Super FC-C is ahead on top speed.
- The International Harvester Super FC-C suits road haulage better on this data: 33% (4.2 km/h / 2.6 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 Super FC-C is 14% heavier (180 kg / 397 lb) than the Fahr D 181 (both unladen weight, as stated by the source).
- The International Harvester Super FC-C has 33% more top speed (4.2 km/h / 2.6 mph) than the Fahr D 181 (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.
- No call on three-point lift: the sources do not state where the lift was measured, so the difference is not a reliable call.
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- 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, hydraulic flow, maximum permissible mass, a creeper range, PTO speeds and PTO independence.
