David Brown 990 Implematic or MAN 2R3?
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 MAN 2R3 is ahead on PTO speeds.
- The MAN 2R3 suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
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 MAN 2R3 offers 1000 rpm at the PTO, which the David Brown 990 Implematic does not (as stated by the sources).
- 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 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 990 Implematic: lift through the full range at the hitch ends, as stated by the source (Traktorenlexikon, “David Brown 990 Implematic”); the 2R3: lift at the hitch ends, as stated by the source (Traktorenlexikon, “MAN 2R3”) — 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, hydraulic flow, maximum permissible mass, a creeper range and PTO independence.
