Fiat 180-90 (DT) or International Harvester 4166?

Which should you choose?

On performance, every comparable figure that differs favours the International Harvester 4166: hydraulic flow. On features, the Fiat 180-90 (DT) is ahead on forward gears.

  • The International Harvester 4166 suits loader and hydraulic implement work better on this data: 23% (11.7 L/min / 3.1 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.
