SOMECA SOM-30 B or Volvo T-31?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the SOM-30 B has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the T-31 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Volvo T-31 suits loader and hydraulic implement work better on this data: 44% (7.3 L/min / 1.9 gpm) more hydraulic flow.
- The Volvo T-31 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 Volvo T-31 has 44% more hydraulic flow (7.3 L/min / 1.9 gpm) than the SOMECA SOM-30 B (both pump flow, as stated by the source).
- The Volvo T-31 is 34% heavier (585 kg / 1,290 lb) than the SOMECA SOM-30 B (both unladen weight, as stated by the source).
- The Volvo T-31 has 50% more top speed (10.0 km/h / 6.2 mph) than the SOMECA SOM-30 B (both top speed forward, as stated by the source).
- The SOMECA SOM-30 B is newer: production began 11 years later. We hold no parts-availability data, so there is no call on parts.
- 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.
- Not comparable on power at the PTO shaft: the SOM-30 B has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the T-31 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the SOM-30 B: lift at the hitch ends, as stated by the source (Traktorenlexikon, “Someca SOM 30 B”); the T-31: lift at an unstated point, as stated by the source (Traktorenlexikon, “Volvo T 31”) — not the same quantity, basis and condition.
- 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.
