Renault 421 M or Renault Super 5-D (A)?
Which should you choose?
On performance, every comparable figure that differs favours the Renault 421 M: hydraulic flow. On features, the Renault Super 5-D (A) is ahead on drive.
- The Renault 421 M suits loader and hydraulic implement work better on this data: 44% (7.9 L/min / 2.1 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 421 M has 44% more hydraulic flow (7.9 L/min / 2.1 gpm) than the Renault Super 5-D (A) (both pump flow, as stated by the source).
- The Renault 421 M is 26% heavier (410 kg / 904 lb) than the Renault Super 5-D (A) (both unladen weight, as stated by the source).
- The Renault Super 5-D (A) is available with four-wheel drive; the Renault 421 M is two-wheel drive (as stated by the sources).
- The Renault 421 M is newer: production began 12 years later. We hold no parts-availability data, so there is no call on parts.
- Even on power at the PTO shaft (both power at the PTO, claimed): the difference is under the 10% threshold for claimed figures, too small to call.
- Even on forward gears (both forward gears, as stated by the source): the difference is under the 25% 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 rpm).
- 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.
