SOMECA SOM-40 B or SOMECA SOM-45?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the SOM-40 B has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-45 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
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?
- 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 three-point lift (both lift at the hitch ends, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, 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 top speed (both top speed forward, 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 PTO independence: every PTO is independent.
- 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 SOM-40 B has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-45 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 and a creeper range.
