Renault 551/551.4 or SAME Centauro?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 551/551.4 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Centauro has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Renault 551/551.4 suits loader and hydraulic implement work better on this data: 67% (10.9 L/min / 2.9 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 Renault 551/551.4 has 67% more hydraulic flow (10.9 L/min / 2.9 gpm) than the SAME Centauro (both pump flow, as stated by the source).
- The Renault 551/551.4 is 15% heavier (310 kg / 683 lb) than the SAME Centauro (both unladen weight, as stated by the source).
- The Renault 551/551.4 has 50% more forward gears (4 gears) than the SAME Centauro (both forward gears, as stated by the source).
- The SAME Centauro is available with four-wheel drive; the Renault 551/551.4 is two-wheel drive (as stated by the sources).
- The Renault 551/551.4 is newer: production began 7 years later. We hold no parts-availability data, so there is no call on parts.
- Even on top speed (both top speed forward, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on PTO speeds: the same speeds (540 rpm).
- Not comparable on power at the PTO shaft: the 551/551.4 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Centauro 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 and PTO independence.
