Bührer Komfort 685 (A) or Bührer GM-29 Super-Six (A)?
Which should you choose?
On performance, every comparable figure that differs favours the Bührer Komfort 685 (A): hydraulic flow. It is also ahead on top speed.
- The Bührer Komfort 685 (A) suits loader and hydraulic implement work better on this data: 107% (20.2 L/min / 5.3 gpm) more hydraulic flow.
- The Bührer Komfort 685 (A) suits road haulage better on this data: 14% (3.0 km/h / 1.9 mph) more top speed.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “similar machines”. 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 685 (A) has 107% more hydraulic flow (20.2 L/min / 5.3 gpm) than the Bührer GM-29 Super-Six (A) (both pump flow, as stated by the source).
- The Bührer Komfort 685 (A) is 21% heavier (600 kg / 1,323 lb) than the Bührer GM-29 Super-Six (A) (both unladen weight, as stated by the source).
- The Bührer Komfort 685 (A) has 14% more top speed (3.0 km/h / 1.9 mph) than the Bührer GM-29 Super-Six (A) (both top speed forward, as stated by the source).
- The Bührer Komfort 685 (A) 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 forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on PTO independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on three-point lift: the Komfort 685 (A): lift through the full range at the hitch ends, as stated by the source (Traktorenlexikon, “Bührer 685/685A”); the GM-29 Super-Six (A): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Bührer GM 29 SUPER-SIX (A)”) — 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 and a creeper range.
