BOLINDER-MUNKTELL BM-15 Terrier or Hermann Lanz D 30?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the BM-15 Terrier has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D 30 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Hermann Lanz D 30 suits loader and hydraulic implement work better on this data: 74% (14.5 L/min / 3.8 gpm) more hydraulic flow.
- The BOLINDER-MUNKTELL BM-15 Terrier suits road haulage better on this data: 52% (10.2 km/h / 6.3 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 Hermann Lanz D 30 has 74% more hydraulic flow (14.5 L/min / 3.8 gpm) than the BOLINDER-MUNKTELL BM-15 Terrier (both pump flow, as stated by the source).
- The Hermann Lanz D 30 is 23% heavier (315 kg / 694 lb) than the BOLINDER-MUNKTELL BM-15 Terrier (both unladen weight, as stated by the source).
- The BOLINDER-MUNKTELL BM-15 Terrier has 52% more top speed (10.2 km/h / 6.3 mph) than the Hermann Lanz D 30 (both top speed forward, as stated by the source).
- 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 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 BM-15 Terrier has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D 30 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, PTO speeds and PTO independence.
