Fiat 615 (DT) or SOMECA 650 (TD)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 615 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 650 (TD) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The SOMECA 650 (TD) suits loader and hydraulic implement work better on this data: 16% (280 kg / 617 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.

| Which is newer, and what about parts? | 1965–1968 | 1971–1976 | Ahead (a fact, not an advantage)The SOMECA 650 (TD) is newer: production began 6 years later. We hold no parts-availability data, so there is no call on parts. |
What does this mean in plain words?
- The SOMECA 650 (TD) has 16% more lift (280 kg / 617 lb) than the Fiat 615 (DT) (both lift at the hitch ends, as stated by the source).
- The SOMECA 650 (TD) offers 1000 rpm at the PTO, which the Fiat 615 (DT) does not (as stated by the sources).
- The SOMECA 650 (TD) is newer: production began 6 years later. We hold no parts-availability data, so there is no call on parts.
- Even on hydraulic flow (both pump flow, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- 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.
- Even on PTO independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the 615 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 650 (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 and a creeper range.
