Renault 58 or SOMECA SOM-40 Super?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 58 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-40 Super has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Renault 58 suits loader and hydraulic implement work better on this data: 54% (700 kg / 1,543 lb) more three-point lift.
- The Renault 58 suits road haulage better on this data: 14% (3.0 km/h / 1.9 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 Renault 58 has 54% more lift (700 kg / 1,543 lb) than the SOMECA SOM-40 Super (both lift at the hitch ends, as stated by the source).
- The SOMECA SOM-40 Super is 35% heavier (655 kg / 1,444 lb) than the Renault 58 (both unladen weight, as stated by the source).
- The Renault 58 has 14% more top speed (3.0 km/h / 1.9 mph) than the SOMECA SOM-40 Super (both top speed forward, as stated by the source).
- The Renault 58 is newer: production began 5 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 figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on PTO independence: every PTO is independent.
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the 58 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-40 Super 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, hydraulic flow, maximum permissible mass and a creeper range.
