Fahr D 133 N or SOMECA 250 (DT)?
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 Fahr D 133N is ahead on forward gears and PTO independence; the SOMECA 250 (DT) is ahead on top speed and drive.
- The Fahr D 133N suits PTO-driven implements (mowers, balers, pumps) better on this data: an independent PTO.
- The SOMECA 250 (DT) suits road haulage better on this data: 34% (6.4 km/h / 4.0 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 Fahr D 133N is 28% heavier (300 kg / 661 lb) than the SOMECA 250 (DT) (both unladen weight, as stated by the source).
- The Fahr D 133N has 33% more forward gears (2 gears) than the SOMECA 250 (DT) (both forward gears, as stated by the source).
- The SOMECA 250 (DT) has 34% more top speed (6.4 km/h / 4.0 mph) than the Fahr D 133N (both top speed forward, as stated by the source).
- The Fahr D 133N has an independent PTO; the SOMECA 250 (DT)’s is dependent (stops with the clutch).
- The SOMECA 250 (DT) is available with four-wheel drive; the Fahr D 133N is two-wheel drive (as stated by the sources).
- The SOMECA 250 (DT) is newer: production began 9 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 D 133 N: lift at an unstated point, as stated by the source (Traktorenlexikon, “Fahr D 133 N”); the 250 (DT): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Someca 250”) — 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.
