John Deere 930 or SOMECA 450 (DT)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 930 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 450 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The John Deere 930 suits loader and hydraulic implement work better on this data: 17% (3.6 L/min / 1.0 gpm) more hydraulic flow.
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 John Deere 930 has 17% more hydraulic flow (3.6 L/min / 1.0 gpm) than the SOMECA 450 (DT) (both pump flow, as stated by the source).
- The John Deere 930 is 26% heavier (445 kg / 981 lb) than the SOMECA 450 (DT) (both unladen weight, as stated by the source).
- The SOMECA 450 (DT) is available with four-wheel drive; the John Deere 930 is two-wheel drive (as stated by the sources).
- The John Deere 930 is newer: production began 6 years later. We hold no parts-availability data, so there is no call on parts.
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on top speed (both top speed forward, as stated by the source): the difference is under the 10% threshold, too small to call.
- Not comparable on power at the PTO shaft: the 930 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 450 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the 930: lift at the hitch ends, as stated by the source (Traktorenlexikon, “John Deere 930”); the 450 (DT): lift through the full range 610 mm behind the ends, as stated by the source (Traktorenlexikon, “Someca 450”) — not the same quantity, basis and condition.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, a creeper range, PTO speeds and PTO independence.
