International Harvester Farmall 544 or SOMECA 550 (DT)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the Farmall 544 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 550 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The International Harvester Farmall 544 suits loader and hydraulic implement work better on this data: 108% (23.6 L/min / 6.2 gpm) more hydraulic flow.
- The International Harvester Farmall 544 suits road haulage better on this data: 25% (6.0 km/h / 3.7 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.
