David Brown 1690 (A) or Ford 7710?
Which should you choose?
On performance, every comparable figure that differs favours the Ford 7710: hydraulic flow. It is also ahead on forward gears and top speed.
- The Ford 7710 suits loader and hydraulic implement work better on this data: 62% (26.3 L/min / 6.9 gpm) more hydraulic flow.
- The Ford 7710 suits road haulage better on this data: 20% (5.0 km/h / 3.1 mph) more top speed.
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 does this mean in plain words?
- The Ford 7710 has 62% more hydraulic flow (26.3 L/min / 6.9 gpm) than the David Brown 1690 (A) (both pump flow, as stated by the source).
- The Ford 7710 is 15% heavier (575 kg / 1,268 lb) than the David Brown 1690 (A) (both unladen weight, as stated by the source).
- The Ford 7710 has 33% more forward gears (4 gears) than the David Brown 1690 (A) (both forward gears, as stated by the source).
- The Ford 7710 has 20% more top speed (5.0 km/h / 3.1 mph) than the David Brown 1690 (A) (both top speed forward, 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 PTO speeds: the same speeds (540, 1000 rpm).
- Even on drive: every machine is available with four-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, a creeper range and PTO independence.
