Bührer Komfort 6105 (A) or Renault 981-4 (S)?
Which should you choose?
On performance, every comparable figure that differs favours the Bührer Komfort 6105 (A): hydraulic flow. On features, the Renault 981-4 (S) is ahead on PTO speeds.
- The Renault 981-4 (S) suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
- The Bührer Komfort 6105 (A) suits loader and hydraulic implement work better on this data: 19% (6.2 L/min / 1.6 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 Bührer Komfort 6105 (A) has 19% more hydraulic flow (6.2 L/min / 1.6 gpm) than the Renault 981-4 (S) (both pump flow, as stated by the source).
- The Renault 981-4 (S) is 14% heavier (535 kg / 1,179 lb) than the Bührer Komfort 6105 (A) (both unladen weight, as stated by the source).
- The Renault 981-4 (S) offers 1000 rpm at the PTO, which the Bührer Komfort 6105 (A) does not (as stated by the sources).
- 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 figures vary by configuration and the ranges overlap.
- Even on a creeper range: every machine offers one.
- Even on drive: every machine is available with four-wheel drive.
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- Not comparable on three-point lift: the Komfort 6105 (A): lift through the full range at the hitch ends, as stated by the source (Traktorenlexikon, “Bührer 6105 (A)”); the 981-4 (S): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Renault 981-4 R7644”) — not the same quantity, basis and condition.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, top speed and PTO independence.
