Bührer GM-29 Super-Six (A) or Fiat 980 (DT)?
Which should you choose?
On performance, every comparable figure that differs favours the Fiat 980 (DT): hydraulic flow and three-point lift. It is also ahead on top speed and PTO speeds.
- The Fiat 980 (DT) suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
- The Fiat 980 (DT) suits loader and hydraulic implement work better on this data: 69% (13.0 L/min / 3.4 gpm) more hydraulic flow and 37% (900 kg / 1,984 lb) more three-point lift.
- The Fiat 980 (DT) 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 “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 Fiat 980 (DT) has 69% more hydraulic flow (13.0 L/min / 3.4 gpm) than the Bührer GM-29 Super-Six (A) (both pump flow, as stated by the source).
- The Fiat 980 (DT) has 37% more lift (900 kg / 1,984 lb) than the Bührer GM-29 Super-Six (A) (both lift at the hitch ends, as stated by the source).
- The Fiat 980 (DT) is 23% heavier (650 kg / 1,433 lb) than the Bührer GM-29 Super-Six (A) (both unladen weight, as stated by the source).
- The Fiat 980 (DT) 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 Fiat 980 (DT) offers 1000 rpm at the PTO, which the Bührer GM-29 Super-Six (A) does not (as stated by the sources).
- The Fiat 980 (DT) is newer: production began 11 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 figures vary by configuration and the ranges overlap.
- Even on drive: every machine is available with four-wheel drive.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, a creeper range and PTO independence.
