Fahr D 25 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 Fahr D 25 is ahead on top speed and PTO independence.
- The Fahr D 25 suits PTO-driven implements (mowers, balers, pumps) better on this data: an independent PTO.
- The Fahr D 25 suits road haulage better on this data: 35% (5.9 km/h / 3.7 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 Fahr D 25 is 24% heavier (346 kg / 763 lb) than the International Harvester Super FC-C (both unladen weight, as stated by the source).
- The Fahr D 25 has 35% more top speed (5.9 km/h / 3.7 mph) than the International Harvester Super FC-C (both top speed forward, as stated by the source).
- The Fahr D 25 has an independent PTO; the International Harvester Super FC-C’s is dependent (stops with the clutch).
- 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 difference is under the 25% threshold, too small to call.
- 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 and PTO speeds.
