Fiat 65-66 S (DT) or Steyr 964 (a)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 65-66 S (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 964 (a) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Steyr 964 (a) suits loader and hydraulic implement work better on this data: 23% (7.8 L/min / 2.1 gpm) more hydraulic flow.
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 Steyr 964 (a) has 23% more hydraulic flow (7.8 L/min / 2.1 gpm) than the Fiat 65-66 S (DT) (both pump flow, as stated by the source).
- The Steyr 964 (a) offers 1000 rpm at the PTO, which the Fiat 65-66 S (DT) does not (as stated by the sources).
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on maximum permissible mass (both maximum permissible mass, as stated by the source): the difference is under the 10% threshold, 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 top speed (both top speed forward, 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.
- 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 65-66 S (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 964 (a) 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 65-66 S (DT): lift through the full range at the hitch ends, as stated by the source (Traktorenlexikon, “Fiatagri 65-66S/65-66 DTS”); the 964 (a): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Steyr 964”) — 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, a creeper range and PTO independence.
