Bührer OP-17 Standard (A) or International Harvester 504?
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 Bührer OP-17 Standard (A) is ahead on forward gears, PTO independence and drive; the International Harvester 504 is ahead on top speed.
- The Bührer OP-17 Standard (A) suits PTO-driven implements (mowers, balers, pumps) better on this data: an independent PTO.
- The Bührer OP-17 Standard (A) suits heavy draft work (ploughing, cultivating) better on this data: four-wheel drive.
- The International Harvester 504 suits road haulage better on this data: 20% (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 Bührer OP-17 Standard (A) has 50% more forward gears (5 gears) than the International Harvester 504 (both forward gears, as stated by the source).
- The International Harvester 504 has 20% more top speed (5.0 km/h / 3.1 mph) than the Bührer OP-17 Standard (A) (both top speed forward, as stated by the source).
- The Bührer OP-17 Standard (A) has an independent PTO; the International Harvester 504’s is dependent (stops with the clutch).
- The Bührer OP-17 Standard (A) is available with four-wheel drive; the International Harvester 504 is two-wheel drive (as stated by the sources).
- The Bührer OP-17 Standard (A) is newer: production began 8 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 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).
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, three-point lift, maximum permissible mass and a creeper range.
