Renault R-56 or Schlüter Super 400 / 400 V?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the R-56 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super 400 / 400 V has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Schlüter Super 400 / 400V suits heavy draft work (ploughing, cultivating) better on this data: 13% (245 kg / 540 lb) heavier and four-wheel drive.
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 Schlüter Super 400 / 400V is 13% heavier (245 kg / 540 lb) than the Renault R-56 (both unladen weight, as stated by the source).
- The Schlüter Super 400 / 400V is available with four-wheel drive; the Renault R-56 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 top speed (both top speed forward, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO independence: every PTO is independent.
- 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 R-56 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super 400 / 400 V 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 R-56: lift at the hitch ends, as stated by the source (Traktorenlexikon, “Renault 56 R7251”); the Super 400 / 400 V: lift at an unstated point, as stated by the source (Traktorenlexikon, “Schlüter Super 400 / 400 V”) — 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, hydraulic flow, maximum permissible mass, a creeper range and PTO speeds.
