Fahr D 90 or Kramer KB 12?
Which should you choose?
On performance, every comparable figure that differs favours the Fahr D 90: maximum permissible mass.
- The Fahr D 90 suits road haulage better on this data: 20% (280 kg / 617 lb) more maximum permissible mass.
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 90 has 20% higher maximum permissible mass (280 kg / 617 lb) than the Kramer KB 12 (both maximum permissible mass, as stated by the source).
- 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.
- No call on three-point lift: the sources do not state where the lift was measured, so the difference is not a reliable 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 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 drive: all two-wheel drive.
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, a creeper range, PTO speeds and PTO independence.
