Deutz-Fahr DX 85 or Fiat 80-66 S (DT)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the DX 85 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 80-66 S (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Deutz-Fahr DX 85 suits loader and hydraulic implement work better on this data: 21% (6.8 L/min / 1.8 gpm) more hydraulic flow and 17% (530 kg / 1,168 lb) more three-point lift.
- The Deutz-Fahr DX 85 suits road haulage better on this data: 22% (1,000 kg / 2,205 lb) more maximum permissible mass.
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.
