Ford 6640 (A) or Hürlimann 908 XT?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 6640 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 908 XT has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Hürlimann 908 XT suits loader and hydraulic implement work better on this data: 26% (9.6 L/min / 2.5 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 Hürlimann 908 XT has 26% more hydraulic flow (9.6 L/min / 2.5 gpm) than the Ford 6640 (A) (both pump flow, as stated by the source).
- The Hürlimann 908 XT has 150% more forward gears (24 gears) than the Ford 6640 (A) (both forward gears, as stated by the source).
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on top speed (both top speed forward, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540, 1000 rpm).
- 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 power at the PTO shaft: the 6640 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 908 XT has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the 6640 (A): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Ford 6640”); the 908 XT: lift through the full range at an unstated point, as stated by the source (Traktorenlexikon, “Hürlimann XT 908”) — 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, a creeper range and PTO independence.
