Hanomag R 45 A/AE or URSUS C-45?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the R 45 A/AE has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the C-45 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “similar machines”. 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 URSUS C-45 is 15% heavier (480 kg / 1,058 lb) than the Hanomag R 45 A/AE (both unladen weight, as stated by the source).
- The Hanomag R 45 A/AE has 67% more forward gears (2 gears) than the URSUS C-45 (both forward gears, as stated by the source).
- 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.
- Not comparable on power at the PTO shaft: the R 45 A/AE has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the C-45 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- 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, a creeper range, PTO speeds and PTO independence.
