J.I. Case 401 or J.I. Case 640?
Which should you choose?
On performance, every comparable figure that differs favours the J.I. Case 401: hydraulic flow.
- The J.I. Case 401 suits loader and hydraulic implement work better on this data: 29% (10.2 L/min / 2.7 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.

| Which may carry more ballast and load? | — | — | No figureNo call on maximum permissible mass: no figure on record for the 401 and the 640. |
| Which has the wider choice of gears? | 8Traktorenlexikon, “Case 401” | 4 to 12Traktorenlexikon, “Case 640” | EvenEven on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap. |

| Which PTO runs independently of the ground drive? | — | independentTraktorenlexikon, “Case 640” | No figureNo call on PTO independence: not stated for the 401. |
| Which drives on both axles? | 2WDTraktorenlexikon, “Case 401” | 2WDTraktorenlexikon, “Case 640” | EvenEven on drive: all two-wheel drive. |
| Which is newer, and what about parts? | 1955–1957 | 1960–1969 | Ahead (a fact, not an advantage)The J.I. Case 640 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 J.I. Case 401 has 29% more hydraulic flow (10.2 L/min / 2.7 gpm) than the J.I. Case 640 (both pump flow, as stated by the source).
- The J.I. Case 401 is 46% heavier (947 kg / 2,088 lb) than the J.I. Case 640 (both unladen weight, as stated by the source).
- The J.I. Case 640 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 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 PTO speeds: the same speeds (540 rpm).
- Even on drive: all two-wheel drive.
- 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.
