Fahr D 400 B or Renault 86?
Which should you choose?
On performance, every comparable figure that differs favours the Renault 86: hydraulic flow. It is also ahead on PTO independence.
- The Renault 86 suits PTO-driven implements (mowers, balers, pumps) better on this data: an independent PTO.
- The Renault 86 suits loader and hydraulic implement work better on this data: 28% (5.2 L/min / 1.4 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.

| Which PTO runs independently of the ground drive? | dependent (stops with the clutch)Traktorenlexikon, “Fahr D 400 B” | independentTraktorenlexikon, “Renault 86 R7281” | AheadThe Renault 86 has an independent PTO; the Fahr D 400 B’s is dependent (stops with the clutch). |

| Which is newer, and what about parts? | 1955–1961 | 1967–1973 | Ahead (a fact, not an advantage)The Renault 86 is newer: production began 12 years later. We hold no parts-availability data, so there is no call on parts. |
What does this mean in plain words?
- The Renault 86 has 28% more hydraulic flow (5.2 L/min / 1.4 gpm) than the Fahr D 400 B (both pump flow, as stated by the source).
- The Fahr D 400 B is 43% heavier (845 kg / 1,863 lb) than the Renault 86 (both unladen weight, as stated by the source).
- The Renault 86 has an independent PTO; the Fahr D 400 B’s is dependent (stops with the clutch).
- The Renault 86 is newer: production began 12 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 forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
- 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.
- 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 speeds.
