BOLINDER-MUNKTELL BM-400 Buster or URSUS 4011?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the BM-400 Buster has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4011 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The BOLINDER-MUNKTELL BM-400 Buster suits road haulage better on this data: 20% (5.0 km/h / 3.1 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?

- 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 BM-400 Buster has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4011 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, maximum permissible mass, a creeper range and PTO independence.
