BOLINDER-MUNKTELL BM-55 or SOMECA DA-50?
Which should you choose?
On performance, every comparable figure that differs favours the BOLINDER-MUNKTELL BM-55: hydraulic flow and three-point lift. It is also ahead on top speed.
- The BOLINDER-MUNKTELL BM-55 suits loader and hydraulic implement work better on this data: 191% (17.6 L/min / 4.6 gpm) more hydraulic flow and 200% (1,600 kg / 3,527 lb) more three-point lift.
- The BOLINDER-MUNKTELL BM-55 suits road haulage better on this data: 36% (8.0 km/h / 5.0 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-55 has 191% more hydraulic flow (17.6 L/min / 4.6 gpm) than the SOMECA DA-50 (both pump flow, as stated by the source).
- The BOLINDER-MUNKTELL BM-55 has 200% more lift (1,600 kg / 3,527 lb) than the SOMECA DA-50 (both lift at the hitch ends, as stated by the source).
- The BOLINDER-MUNKTELL BM-55 is 56% heavier (1,161 kg / 2,560 lb) than the SOMECA DA-50 (both unladen weight, as stated by the source).
- The BOLINDER-MUNKTELL BM-55 has 36% more top speed (8.0 km/h / 5.0 mph) than the SOMECA DA-50 (both top speed forward, 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.
- 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 PTO speeds: the same speeds (540 rpm).
- 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, maximum permissible mass, a creeper range and PTO independence.
