Bührer PF-21 Super (A) or Deutz (KHD) F4L 514/5?
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 PF-21 Super (A) is ahead on forward gears, PTO independence and drive; the Deutz F4L 514/5 is ahead on top speed.
- The Bührer PF-21 Super (A) suits PTO-driven implements (mowers, balers, pumps) better on this data: an independent PTO.
- The Deutz F4L 514/5 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 F4L 514/5 is 24% heavier (595 kg / 1,312 lb) than the Bührer PF-21 Super (A) (both unladen weight, as stated by the source).
- The Bührer PF-21 Super (A) has 114% more forward gears (8 gears) than the Deutz F4L 514/5 (both forward gears, as stated by the source).
- The Deutz F4L 514/5 has 20% more top speed (5.0 km/h / 3.1 mph) than the Bührer PF-21 Super (A) (both top speed forward, as stated by the source).
- The Bührer PF-21 Super (A) has an independent PTO; the Deutz F4L 514/5’s is dependent (stops with the clutch).
- The Bührer PF-21 Super (A) is available with four-wheel drive; the Deutz F4L 514/5 is two-wheel drive (as stated by the sources).
- The Bührer PF-21 Super (A) is newer: production began 12 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.
- Not comparable on three-point lift: the PF-21 Super (A): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Bührer PF 21 Super(A)”); the F4L 514/5: lift at an unstated point, as stated by the source (Traktorenlexikon, “Deutz F4L 514/5”) — 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 speeds.
