Deutz-Fahr AgroStar 6.31 or John Deere 3650 A?
Which should you choose?
On performance, every comparable figure that differs favours the Deutz-Fahr AgroStar 6.31: three-point lift. On features, the John Deere 3650A is ahead on PTO speeds.
- The John Deere 3650A suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 540 rpm.
- The Deutz-Fahr AgroStar 6.31 suits loader and hydraulic implement work better on this data: 44% (1,974 kg / 4,352 lb) more three-point lift.
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 Deutz-Fahr AgroStar 6.31 has 44% more lift (1,974 kg / 4,352 lb) than the John Deere 3650A (both lift at the hitch ends, as stated by the source).
- The John Deere 3650A offers 540 rpm at the PTO, which the Deutz-Fahr AgroStar 6.31 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 hydraulic flow (both pump flow, as stated by the source): the difference is under the 10% threshold, 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 maximum permissible mass (both maximum permissible mass, as stated by the source): the difference is under the 10% threshold, too small to call.

- 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 and a creeper range.
