John Deere 6630 or Renault Ares 636 RZ?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 6630 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Ares 636 RZ has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
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 Ares 636 RZ is 12% heavier (640 kg / 1,411 lb) than the John Deere 6630 (both unladen weight, as stated by the source).
- The John Deere 6630 is newer: production began 6 years later. We hold no parts-availability data, so there is no call on parts.
- Even on maximum permissible mass (both maximum permissible mass, as stated by the source): the difference is under the 10% threshold, too small to call.
- 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, 1000 rpm).
- Even on PTO independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the 6630 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Ares 636 RZ has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- No call on forward gears: sources disagree on the figure for the 6630.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, three-point lift and a creeper range.
