J.I. Case 930 or J.I. Case 931 GP?
Which should you choose?
On performance, no comparable figure differs by more than its threshold: on this data the machines are level.
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?
| Question | 930 | 931 GP | Call |
|---|---|---|---|
| Which puts more power through the PTO shaft? | 61.8 kW (82.9 hp)Traktorenlexikon, “Case 930” | 61.8 kW (82.9 hp)Traktorenlexikon, “Case 931” | EvenEven 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. |
| Which turns a litre of fuel into more work at the shaft? | — | — | No figureNo call on fuel efficiency at the shaft: no figure on record for the 930 and the 931 GP. |
| Which pulls harder at the drawbar? | — | — | No figureNo call on drawbar power: no figure on record for the 930 and the 931 GP. |
| Which pumps more oil for implements? | 58.7 L/min (15.5 gpm)Traktorenlexikon, “Case 930” | 58.7 L/min (15.5 gpm)Traktorenlexikon, “Case 931” | EvenEven on hydraulic flow (both pump flow, as stated by the source): the difference is under the 10% threshold, too small to call. |
| Which lifts more on the three-point hitch? | — | — | No figureNo call on three-point lift: no figure on record for the 930 and the 931 GP. |
| Which is heavier, for traction? | 3,970 kg (8,752 lb)Traktorenlexikon, “Case 930” | 4,044 kg (8,915 lb)Traktorenlexikon, “Case 931” | 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 930 and the 931 GP. |
| Which has the wider choice of gears? | 6 to 8Traktorenlexikon, “Case 930” | 6 to 8Traktorenlexikon, “Case 931” | 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 930 and the 931 GP. |
| Which is faster on the road? | 25 km/h (15.5 mph)Traktorenlexikon, “Case 930” | 25 km/h (15.5 mph)Traktorenlexikon, “Case 931” | 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 930” | 540/1000 rpmTraktorenlexikon, “Case 931” | EvenEven on PTO speeds: the same speeds (540, 1000 rpm). |
| Which PTO runs independently of the ground drive? | independentTraktorenlexikon, “Case 930” | independentTraktorenlexikon, “Case 931” | EvenEven on PTO independence: every PTO is independent. |
| Which drives on both axles? | 2WDTraktorenlexikon, “Case 930” | 2WDTraktorenlexikon, “Case 931” | EvenEven on drive: all two-wheel drive. |
| Which is newer, and what about parts? | 1962–1969 | 1959–1969 | EvenSame era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts. |
What does this mean in plain words?
- 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 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 speeds: the same speeds (540, 1000 rpm).
- Even on PTO independence: every PTO is independent.
- Even on drive: all two-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 and a creeper range.
