Deutz (KHD) D 25.2 or International Harvester F-137 D?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D 25.2 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the F-137 D has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Deutz D 25.2 suits loader and hydraulic implement work better on this data: 33% (4.0 L/min / 1.1 gpm) more hydraulic flow.
- The Deutz D 25.2 suits road haulage better on this data: 11% (2.0 km/h / 1.2 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.
