CASE-INTERNATIONAL 685 (DT) or J.I. Case 1390 (DT)?
Which should you choose?
On performance, no comparable figure differs by more than its threshold: on this data the machines are level. On features, the CASE-INTERNATIONAL 685 (DT) is ahead on PTO speeds.
- The CASE-INTERNATIONAL 685 (DT) suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
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 decides it, question by question?

| Which pulls harder at the drawbar? | — | — | No figureNo call on drawbar power: no figure on record for the 685 (DT) and the 1390 (DT). |
| Which pumps more oil for implements? | — | 32.9 L/min (8.7 gpm)Traktorenlexikon, “Case 1390” | No figureNo call on hydraulic flow: no figure on record for the 685 (DT). |
| Which lifts more on the three-point hitch? | 2,380 kg (5,247 lb)Traktorenlexikon, “Case-IH 685” | — | No figureNo call on three-point lift: no figure on record for the 1390 (DT). |
| Which is heavier, for traction? | 2,647 kg (5,836 lb)Traktorenlexikon, “Case-IH 685” | 2,886 kg (6,363 lb)Traktorenlexikon, “Case 1390” | EvenEven on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call. |
| Which may carry more ballast and load? | — | — | No figureNo call on maximum permissible mass: no figure on record for the 685 (DT) and the 1390 (DT). |
| Which has the wider choice of gears? | 8 to 16Traktorenlexikon, “Case-IH 685” | 12Traktorenlexikon, “Case 1390” | EvenEven on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap. |
| Which offers a creeper range? | — | — | No figureNo call on a creeper range: not stated for the 685 (DT) and the 1390 (DT). |
| Which is faster on the road? | 30 km/h (18.6 mph)Traktorenlexikon, “Case-IH 685” | 30 km/h (18.6 mph)Traktorenlexikon, “Case 1390” | EvenEven on top speed (both top speed forward, as stated by the source): the difference is under the 10% threshold, too small to call. |
| Which offers more PTO speeds? | 540/1000 rpmTraktorenlexikon, “Case-IH 685” | 540 rpmTraktorenlexikon, “Case 1390” | AheadThe CASE-INTERNATIONAL 685 (DT) offers 1000 rpm at the PTO, which the J.I. Case 1390 (DT) does not (as stated by the sources). |
| Which PTO runs independently of the ground drive? | independentTraktorenlexikon, “Case-IH 685” | independentTraktorenlexikon, “Case 1390” | EvenEven on PTO independence: every PTO is independent. |
| Which drives on both axles? | Two-wheel or four-wheel driveTraktorenlexikon, “Case-IH 685” | Two-wheel or four-wheel driveTraktorenlexikon, “Case 1390” | EvenEven on drive: every machine is available with four-wheel drive. |
| Which is newer, and what about parts? | 1985–1990 | 1980–1984 | Ahead (a fact, not an advantage)The CASE-INTERNATIONAL 685 (DT) is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts. |
What does this mean in plain words?
- The CASE-INTERNATIONAL 685 (DT) offers 1000 rpm at the PTO, which the J.I. Case 1390 (DT) does not (as stated by the sources).
- The CASE-INTERNATIONAL 685 (DT) is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts.
- 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 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.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, three-point lift, maximum permissible mass and a creeper range.
