Bührer RP-21 Super (A) or IMR-RAKOVICA R-76 Standard?
Which should you choose?
On performance, every comparable figure that differs favours the IMR-RAKOVICA R-76 Standard: hydraulic flow. It is also ahead on top speed. On features, the Bührer RP-21 Super (A) is ahead on forward gears and drive.
- The IMR-RAKOVICA R-76 Standard suits loader and hydraulic implement work better on this data: 53% (10.4 L/min / 2.7 gpm) more hydraulic flow.
- The Bührer RP-21 Super (A) suits heavy draft work (ploughing, cultivating) better on this data: 16% (369 kg / 814 lb) heavier and four-wheel drive.
- The IMR-RAKOVICA R-76 Standard 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 IMR-RAKOVICA R-76 Standard has 53% more hydraulic flow (10.4 L/min / 2.7 gpm) than the Bührer RP-21 Super (A) (both pump flow, as stated by the source).

- Even on PTO speeds: the same speeds (540 rpm).
- Even on PTO independence: every PTO is independent.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass and a creeper range.
