Massey Ferguson MF 6499 A or Massey Ferguson MF 8450?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the MF 6499 A has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the MF 8450 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
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 Massey Ferguson 8450 is 15% heavier (1,180 kg / 2,601 lb) than the Massey Ferguson 6499A (both unladen weight, as stated by the source).
- Transmissions differ in kind: the Massey Ferguson 6499A has 24 to 32 forward gears and the Massey Ferguson 8450 is stepless (CVT) — not called.
- Even on top speed (both top speed forward, as stated by the source): the figures vary by configuration and the ranges overlap.
- 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.
- Not comparable on power at the PTO shaft: the MF 6499 A has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the MF 8450 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- 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.
