J.I. Case 4690 or Massey Ferguson MF 4840?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 4690 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the MF 4840 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 “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 Massey Ferguson 4840 is 17% heavier (1,700 kg / 3,748 lb) than the J.I. Case 4690 (both unladen weight, as stated by the source).
- The Massey Ferguson 4840 has 50% more forward gears (6 gears) than the J.I. Case 4690 (both forward gears, as stated by the source).
- Even on top speed (both top speed forward, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on PTO speeds: the same speeds (1000 rpm).
- 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 4690 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the MF 4840 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the 4690: lift through the full range 610 mm behind the ends, as stated by the source (Traktorenlexikon, “Case 4690”); the MF 4840: lift at an unstated point, as stated by the source (Traktorenlexikon, “Massey Ferguson MF 4840”) — 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.
