International Harvester D-439 or Lamborghini R-240 (DT)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D-439 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the R-240 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The International Harvester D-439 suits loader and hydraulic implement work better on this data: 44% (7.3 L/min / 1.9 gpm) more hydraulic flow.
- The Lamborghini R-240 (DT) suits heavy draft work (ploughing, cultivating) better on this data: four-wheel drive.
- The Lamborghini R-240 (DT) 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.

What does this mean in plain words?
