Fiat 55-86 F (F/DT) or New Holland 4135 (A)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 55-86 F (F/DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4135 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The New Holland 4135 (A) suits loader and hydraulic implement work better on this data: 26% (625 kg / 1,378 lb) more three-point lift.
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 New Holland 4135 (A) has 26% more lift (625 kg / 1,378 lb) than the Fiat 55-86 F (F/DT) (both lift at the hitch ends, as stated by the source).
- The New Holland 4135 (A) is 38% heavier (728 kg / 1,605 lb) than the Fiat 55-86 F (F/DT) (both unladen weight, as stated by the source).
- 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 PTO speeds: the same speeds (540 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 55-86 F (F/DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4135 (A) 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, maximum permissible mass, a creeper range and PTO independence.
