BOLINDER-MUNKTELL BM-20 or BUKH 452 (Super)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the BM-20 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 452 (Super) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The BUKH 452 (Super) suits road haulage better on this data: 15% (3.0 km/h / 1.9 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 BOLINDER-MUNKTELL BM-20 is 13% heavier (300 kg / 661 lb) than the BUKH 452 (Super) (both unladen weight, as stated by the source).
- The BUKH 452 (Super) has 60% more forward gears (3 gears) than the BOLINDER-MUNKTELL BM-20 (both forward gears, as stated by the source).
- The BUKH 452 (Super) has 15% more top speed (3.0 km/h / 1.9 mph) than the BOLINDER-MUNKTELL BM-20 (both top speed forward, as stated by the source).
- The BUKH 452 (Super) is newer: production began 15 years later. We hold no parts-availability data, so there is no call on parts.
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the BM-20 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 452 (Super) 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.
