Fiat 680 (DT) or J.I. Case 1390 (DT)?
Which should you choose?
On performance, every comparable figure that differs favours the J.I. Case 1390 (DT): hydraulic flow. On features, the Fiat 680 (DT) is ahead on PTO speeds.
- The Fiat 680 (DT) suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
- The J.I. Case 1390 (DT) suits loader and hydraulic implement work better on this data: 28% (7.1 L/min / 1.9 gpm) more hydraulic flow.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “similar machines”. 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 J.I. Case 1390 (DT) has 28% more hydraulic flow (7.1 L/min / 1.9 gpm) than the Fiat 680 (DT) (both pump flow, as stated by the source).
- The Fiat 680 (DT) is 14% heavier (414 kg / 913 lb) than the J.I. Case 1390 (DT) (both unladen weight, as stated by the source).
- The Fiat 680 (DT) offers 1000 rpm at the PTO, which the J.I. Case 1390 (DT) does not (as stated by the sources).
- Even on power at the PTO shaft (both power at the PTO, claimed): the difference is under the 10% threshold for claimed figures, 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 figures vary by configuration and the ranges overlap.
- Even on drive: every machine is available with four-wheel drive.
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, three-point lift, maximum permissible mass, a creeper range and PTO independence.
