Deutz (KHD) D 50.1 S or International Harvester 584?
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 Deutz D 50.1 S is ahead on top speed; the International Harvester 584 is ahead on PTO speeds and drive.
- The International Harvester 584 suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
- The International Harvester 584 suits heavy draft work (ploughing, cultivating) better on this data: four-wheel drive.
- The Deutz D 50.1 S 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 Deutz D 50.1 S has 20% more top speed (5.0 km/h / 3.1 mph) than the International Harvester 584 (both top speed forward, as stated by the source).
- The International Harvester 584 offers 1000 rpm at the PTO, which the Deutz D 50.1 S does not (as stated by the sources).
- The International Harvester 584 is available with four-wheel drive; the Deutz D 50.1 S is two-wheel drive (as stated by the sources).
- The International Harvester 584 is newer: production began 15 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 figures vary by configuration and the ranges overlap.
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- Not comparable on three-point lift: the D 50.1 S: lift at an unstated point, as stated by the source (Traktorenlexikon, “Deutz D 50 S (D 55)”); the 584: lift at the hitch ends, as stated by the source (Traktorenlexikon, “IHC 584”) — not the same quantity, basis and condition.
- 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 independence.
