Güldner AX or Kramer KB 12?
Which should you choose?
On performance, no comparable figure differs by more than its threshold: on this data the machines are level.
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 Kramer KB 12 is 38% heavier (300 kg / 661 lb) than the Güldner AX (both unladen weight, 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 maximum permissible mass (both maximum permissible mass, 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 difference is under the 25% threshold, too small to call.
- 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.
