Bührer RP-21 Super (A) or SOMECA 780 (TD)?
Which should you choose?
On performance, every comparable figure that differs favours the SOMECA 780 (TD): hydraulic flow and three-point lift. It is also ahead on PTO speeds.
- The SOMECA 780 (TD) suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
- The SOMECA 780 (TD) suits loader and hydraulic implement work better on this data: 35% (6.8 L/min / 1.8 gpm) more hydraulic flow and 52% (1,150 kg / 2,535 lb) more three-point lift.
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.

| Which is newer, and what about parts? | 1969–1975 | 1975–1983 | Ahead (a fact, not an advantage)The SOMECA 780 (TD) is newer: production began 6 years later. We hold no parts-availability data, so there is no call on parts. |
What does this mean in plain words?
- The SOMECA 780 (TD) has 35% more hydraulic flow (6.8 L/min / 1.8 gpm) than the Bührer RP-21 Super (A) (both pump flow, as stated by the source).
- The SOMECA 780 (TD) has 52% more lift (1,150 kg / 2,535 lb) than the Bührer RP-21 Super (A) (both lift at the hitch ends, as stated by the source).
- The SOMECA 780 (TD) offers 1000 rpm at the PTO, which the Bührer RP-21 Super (A) does not (as stated by the sources).
- The SOMECA 780 (TD) is newer: production began 6 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 weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, 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.
