International Harvester D-436 or International Harvester 444?

Which should you choose?

On performance, every comparable figure that differs favours the International Harvester 444: hydraulic flow. It is also ahead on top speed and drive.

  • The International Harvester 444 suits loader and hydraulic implement work better on this data: 14% (3.3 L/min / 0.9 gpm) more hydraulic flow.
  • The International Harvester 444 suits heavy draft work (ploughing, cultivating) better on this data: four-wheel drive.
  • The International Harvester 444 suits road haulage better on this data: 25% (5.0 km/h / 3.1 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.

Which is newer, and what about parts?1959–19621972–1977Ahead (a fact, not an advantage)The International Harvester 444 is newer: production began 13 years later. We hold no parts-availability data, so there is no call on parts.

What does this mean in plain words?

  • The International Harvester 444 has 14% more hydraulic flow (3.3 L/min / 0.9 gpm) than the International Harvester D-436 (both pump flow, as stated by the source).
  • The International Harvester 444 has 25% more top speed (5.0 km/h / 3.1 mph) than the International Harvester D-436 (both top speed forward, as stated by the source).
  • The International Harvester 444 is available with four-wheel drive; the International Harvester D-436 is two-wheel drive (as stated by the sources).
  • The International Harvester 444 is newer: production began 13 years later. We hold no parts-availability data, so there is no call on parts.
  • Even on power at the PTO shaft (both power at the PTO, claimed): the difference is under the 10% threshold for claimed figures, too small to call.
  • Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
  • Even on forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
  • Even on PTO speeds: the same speeds (540 rpm).
  • Even on PTO independence: every PTO is independent.
  • No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, three-point lift, maximum permissible mass and a creeper range.
