Deutz (KHD) D 50.1S (D 55) or Fordson County Super IV?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D 50.1S (D 55) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super IV has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Fordson County Super IV suits heavy draft work (ploughing, cultivating) better on this data: 26% (580 kg / 1,279 lb) heavier and four-wheel drive.
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 Fordson County Super IV is 26% heavier (580 kg / 1,279 lb) than the Deutz D 50.1S (D 55) (both unladen weight, as stated by the source).
- The Deutz D 50.1S (D 55) has 33% more forward gears (2 gears) than the Fordson County Super IV (both forward gears, as stated by the source).
- The Fordson County Super IV is available with four-wheel drive; the Deutz D 50.1S (D 55) is two-wheel drive (as stated by the sources).
- Even on top speed (both top speed forward, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540 rpm).
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- Not comparable on power at the PTO shaft: the D 50.1S (D 55) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super IV has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the D 50.1S (D 55): lift at an unstated point, as stated by the source (Traktorenlexikon, “Deutz D 50.1S (D 55)”); the Super IV: lift at the hitch ends, as stated by the source (Traktorenlexikon, “Fordson County Super IV”) — 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.
