Fiat 70-66 F (DT/F) or International Harvester Hydro 70?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 70-66 F (DT/F) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Hydro 70 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The International Harvester Hydro 70 suits loader and hydraulic implement work better on this data: 39% (12.7 L/min / 3.4 gpm) more hydraulic flow.
- The International Harvester Hydro 70 suits road haulage better on this data: 13% (4.0 km/h / 2.5 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.
