Deutz-Fahr AgroStar 6.31 or International Harvester Hydro 186?

Which should you choose?

On performance, every comparable figure that differs favours the Deutz-Fahr AgroStar 6.31: hydraulic flow and three-point lift. It is also ahead on drive. On features, the International Harvester Hydro 186 is ahead on PTO speeds.

  • The International Harvester Hydro 186 suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 540 rpm.
  • The Deutz-Fahr AgroStar 6.31 suits loader and hydraulic implement work better on this data: 28% (12.6 L/min / 3.3 gpm) more hydraulic flow and 145% (3,845 kg / 8,477 lb) more three-point lift.

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.
