International Harvester D-320 Farmall or SOMECA SOM-271?

Which should you choose?

The data can’t decide this. Power at the PTO shaft cannot be compared: the D-320 Farmall has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-271 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.

  • The SOMECA SOM-271 suits road haulage better on this data: 15% (3.0 km/h / 1.9 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.
