Fahr D 30 UL or Nuffield Universal-3 (3 DL)?
Which should you choose?
On performance, no comparable figure differs by more than its threshold: on this data the machines are level.
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 decides it, question by question?

| Which is newer, and what about parts? | 1951 | 1957–1961 | Ahead (a fact, not an advantage)The Nuffield Universal-3 (3 DL) is newer: production began 6 years later. We hold no parts-availability data, so there is no call on parts. |
What does this mean in plain words?
- The Nuffield Universal-3 (3 DL) is newer: production began 6 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 forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
- Even on top speed (both top speed forward, 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).
- Even on drive: all two-wheel drive.
- Not comparable on three-point lift: the D 30 UL: lift at an unstated point, as stated by the source (Traktorenlexikon, “Fahr D 30 UL”); the Universal-3 (3 DL): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Nuffield Universal 3 (1957-1961)”) — 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.
