SOMECA SOM-431 V/E or SOMECA SOM-481 GD?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the SOM-431 V/E has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-481 GD has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The SOMECA SOM-481 GD suits road haulage better on this data: 29% (5.0 km/h / 3.1 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 SOMECA SOM-481 GD is 17% heavier (240 kg / 529 lb) than the SOMECA SOM-431 V/E (both unladen weight, as stated by the source).
- The SOMECA SOM-481 GD has 29% more top speed (5.0 km/h / 3.1 mph) than the SOMECA SOM-431 V/E (both top speed forward, as stated by the source).
- 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 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.
- Not comparable on power at the PTO shaft: the SOM-431 V/E has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-481 GD 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-431 V/E: lift at the hitch ends, as stated by the source (Traktorenlexikon, “Someca SOM 431”); the SOM-481 GD: lift through the full range at the hitch ends, as stated by the source (Traktorenlexikon, “Someca SOM 481”) — 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.
