Fahr D 28 or SOMECA SOM-30?
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 SOMECA SOM-30 is ahead on top speed; the Fahr D 28 is ahead on PTO independence.
- The Fahr D 28 suits PTO-driven implements (mowers, balers, pumps) better on this data: an independent PTO.
- The SOMECA SOM-30 suits road haulage better on this data: 12% (2.4 km/h / 1.5 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 28 is 31% heavier (470 kg / 1,036 lb) than the SOMECA SOM-30 (both unladen weight, as stated by the source).
- The SOMECA SOM-30 has 12% more top speed (2.4 km/h / 1.5 mph) than the Fahr D 28 (both top speed forward, as stated by the source).
- The Fahr D 28 has an independent PTO; the SOMECA SOM-30’s is dependent (stops with the clutch).
- The SOMECA SOM-30 is newer: production began 10 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 difference is under the 25% threshold, too small to call.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on drive: all two-wheel drive.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, three-point lift, maximum permissible mass and a creeper range.
