David Brown 1690 (A) or Fiat 100-90 (DT)?
Which should you choose?
On performance, no comparable figure differs by more than its threshold: on this data the machines are level. On features, the Fiat 100-90 (DT) is ahead on top speed.
- The Fiat 100-90 (DT) 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 Fiat 100-90 (DT) 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 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 difference is under the 25% 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: 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, hydraulic flow, three-point lift, maximum permissible mass and a creeper range.
