David Brown 770 Selematic or J.I. Case 440?
Which should you choose?
On performance, every comparable figure that differs favours the J.I. Case 440: hydraulic flow.
- The J.I. Case 440 suits loader and hydraulic implement work better on this data: 58% (11.8 L/min / 3.1 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.

Case 440 has 58% more hydraulic flow (11.8 L/min / 3.1 gpm) than the David Brown 770 Selematic (both pump flow, as stated by the source). |

| Which PTO runs independently of the ground drive? | — | independentTraktorenlexikon, “Case 440” | No figureNo call on PTO independence: not stated for the 770 Selematic. |
| Which drives on both axles? | 2WDTraktorenlexikon, “David Brown 770” | 2WDTraktorenlexikon, “Case 440” | EvenEven on drive: all two-wheel drive. |
| Which is newer, and what about parts? | 1965–1970 | 1960–1969 | Ahead (a fact, not an advantage)The David Brown 770 Selematic 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 440 has 58% more hydraulic flow (11.8 L/min / 3.1 gpm) than the David Brown 770 Selematic (both pump flow, as stated by the source).
- The David Brown 770 Selematic 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 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.
