Porsche-Diesel Super L 318 or SOMECA SOM-411/B?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the Super L 318 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-411/B has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Porsche-Diesel Super L 318 suits loader and hydraulic implement work better on this data: 20% (3.3 L/min / 0.9 gpm) more hydraulic flow.
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 Porsche-Diesel Super L 318 has 20% more hydraulic flow (3.3 L/min / 0.9 gpm) than the SOMECA SOM-411/B (both pump flow, as stated by the source).
- The Porsche-Diesel Super L 318 is 53% heavier (700 kg / 1,543 lb) than the SOMECA SOM-411/B (both unladen weight, as stated by the source).
- The Porsche-Diesel Super L 318 has 33% more forward gears (2 gears) than the SOMECA SOM-411/B (both forward gears, as stated by the source).
- Even on top speed (both top speed forward, as stated by the source): the figures vary by configuration and the ranges overlap.
- 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 Super L 318 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-411/B 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.
