Bührer RP-21 Super (A) or Renault 74-14 RS?
Which should you choose?
The figures split: the Renault 74-14 RS is ahead on hydraulic flow, top speed and PTO speeds; the Bührer RP-21 Super (A) is ahead on three-point lift.
- The Renault 74-14 RS suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
- The Renault 74-14 RS suits road haulage better on this data: 20% (5.0 km/h / 3.1 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 74-14 RS has 105% more hydraulic flow (20.4 L/min / 5.4 gpm) than the Bührer RP-21 Super (A) (both pump flow, as stated by the source).
- The Bührer RP-21 Super (A) has 31% more lift (520 kg / 1,146 lb) than the Renault 74-14 RS (both lift at the hitch ends, as stated by the source).
