International Harvester 4156 or Steyr 8170 a?
Which should you choose?
On performance, every comparable figure that differs favours the International Harvester 4156: hydraulic flow. On features, the Steyr 8170 a is ahead on forward gears and PTO speeds.
- The Steyr 8170 a suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 540 rpm.
- The International Harvester 4156 suits loader and hydraulic implement work better on this data: 49% (20.5 L/min / 5.4 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.

What does this mean in plain words?
- The International Harvester 4156 has 49% more hydraulic flow (20.5 L/min / 5.4 gpm) than the Steyr 8170 a (both pump flow, as stated by the source).
- The International Harvester 4156 is 14% heavier (859 kg / 1,894 lb) than the Steyr 8170 a (both unladen weight, as stated by the source).
