Nuffield 3/45 (345) or SOMECA 470 (TD)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 3/45 (345) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 470 (TD) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Nuffield 3/45 (345) suits loader and hydraulic implement work better on this data: 46% (9.8 L/min / 2.6 gpm) more hydraulic flow and 30% (207 kg / 456 lb) more three-point lift.
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?
- The Nuffield 3/45 (345) has 46% more hydraulic flow (9.8 L/min / 2.6 gpm) than the SOMECA 470 (TD) (both pump flow, as stated by the source).

- Not comparable on power at the PTO shaft: the 3/45 (345) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 470 (TD) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, a creeper range and PTO independence.
