BOLINDER-MUNKTELL BM-32 or International Harvester D-439?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the BM-32 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D-439 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The BOLINDER-MUNKTELL BM-32 suits road haulage better on this data: 50% (10.0 km/h / 6.2 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-32 is 31% heavier (537 kg / 1,184 lb) than the International Harvester D-439 (both unladen weight, as stated by the source).
- The International Harvester D-439 has 60% more forward gears (3 gears) than the BOLINDER-MUNKTELL BM-32 (both forward gears, as stated by the source).
- The BOLINDER-MUNKTELL BM-32 has 50% more top speed (10.0 km/h / 6.2 mph) than the International Harvester D-439 (both top speed forward, as stated by the source).
- The International Harvester D-439 is newer: production began 12 years later. We hold no parts-availability data, so there is no call on parts.
- Even on hydraulic flow (both pump flow, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the BM-32 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D-439 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, three-point lift, maximum permissible mass, a creeper range and PTO independence.
