Bührer Komfort 685 (A) or ZETOR 12011/12045?
Which should you choose?
On performance, no comparable figure differs by more than its threshold: on this data the machines are level. On features, the ZETOR 12011/12045 is ahead on top speed and PTO speeds.
- The ZETOR 12011/12045 suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
- The ZETOR 12011/12045 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 “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 ZETOR 12011/12045 is 22% heavier (755 kg / 1,664 lb) than the Bührer Komfort 685 (A) (both unladen weight, as stated by the source).
- The ZETOR 12011/12045 has 20% more top speed (5.0 km/h / 3.1 mph) than the Bührer Komfort 685 (A) (both top speed forward, as stated by the source).
- The ZETOR 12011/12045 offers 1000 rpm at the PTO, which the Bührer Komfort 685 (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 difference is under the 25% threshold, too small to call.
- 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 685 (A): lift through the full range at the hitch ends, as stated by the source (Traktorenlexikon, “Bührer 685/685A”); the 12011/12045: lift at the hitch ends, as stated by the source (Traktorenlexikon, “Zetor 12011/12045”) — 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, hydraulic flow, maximum permissible mass, a creeper range and PTO independence.
