Deutz (KHD) D 4506 or International Harvester D-440?

Which should you choose?

The data can’t decide this. Power at the PTO shaft cannot be compared: the D 4506 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D-440 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.

  • The Deutz D 4506 suits heavy draft work (ploughing, cultivating) better on this data: four-wheel drive.

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.
