SOMECA 450 (DT) or SOMECA SOM-431 V/E?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 450 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the 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 SOMECA 450 (DT) suits loader and hydraulic implement work better on this data: 32% (5.3 L/min / 1.4 gpm) more hydraulic flow.
- The SOMECA 450 (DT) suits heavy draft work (ploughing, cultivating) better on this data: 20% (290 kg / 639 lb) heavier and four-wheel drive.
- The SOMECA 450 (DT) suits road haulage better on this data: 47% (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 SOMECA 450 (DT) has 32% more hydraulic flow (5.3 L/min / 1.4 gpm) than the SOMECA SOM-431 V/E (both pump flow, as stated by the source).
- The SOMECA 450 (DT) is 20% heavier (290 kg / 639 lb) than the SOMECA SOM-431 V/E (both unladen weight, as stated by the source).
- The SOMECA 450 (DT) has 47% more top speed (8.0 km/h / 5.0 mph) than the SOMECA SOM-431 V/E (both top speed forward, as stated by the source).
- The SOMECA 450 (DT) is available with four-wheel drive; the SOMECA SOM-431 V/E is two-wheel drive (as stated by the sources).
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540 rpm).
- 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 450 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-431 V/E 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 450 (DT): lift through the full range 610 mm behind the ends, as stated by the source (Traktorenlexikon, “Someca 450”); the SOM-431 V/E: lift at the hitch ends, as stated by the source (Traktorenlexikon, “Someca SOM 431”) — 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.
