David Brown 770 Selematic or International Harvester 276?
Which should you choose?
On performance, every comparable figure that differs favours the International Harvester 276: hydraulic flow. On features, the David Brown 770 Selematic is ahead on forward gears.
- The International Harvester 276 suits loader and hydraulic implement work better on this data: 23% (4.6 L/min / 1.2 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 International Harvester 276 has 23% more hydraulic flow (4.6 L/min / 1.2 gpm) than the David Brown 770 Selematic (both pump flow, as stated by the source).
- The International Harvester 276 is 16% heavier (233 kg / 514 lb) than the David Brown 770 Selematic (both unladen weight, as stated by the source).
- The David Brown 770 Selematic has 50% more forward gears (4 gears) than the International Harvester 276 (both forward gears, as stated by the source).
- 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 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 rpm).
- 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.
- Not comparable on three-point lift: the 770 Selematic: lift through the full range at the hitch ends, as stated by the source (Traktorenlexikon, “David Brown 770”); the 276: lift at an unstated point, as stated by the source (Traktorenlexikon, “McCormick 276”) — not the same quantity, basis and condition.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, a creeper range and PTO independence.
