David Brown 4600 Selectmatic or Massey Ferguson MF 254 S (A)?
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 Massey Ferguson MF 254 S (A) is ahead on drive.
- The Massey Ferguson MF 254 S (A) suits heavy draft work (ploughing, cultivating) better on this data: 45% (810 kg / 1,786 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 Massey Ferguson MF 254 S (A) is 45% heavier (810 kg / 1,786 lb) than the David Brown 4600 Selectmatic (both unladen weight, as stated by the source).
- The Massey Ferguson MF 254 S (A) is available with four-wheel drive; the David Brown 4600 Selectmatic is two-wheel drive (as stated by the sources).
- The Massey Ferguson MF 254 S (A) is newer: production began 14 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 forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- 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, 1000 rpm).
- Not comparable on three-point lift: the 4600 Selectmatic: lift through the full range at the hitch ends, as stated by the source (Traktorenlexikon, “David Brown 4600”); the MF 254 S (A): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Massey Ferguson MF 254 (S)”) — 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.
