Fiat 550 (DT) or Hürlimann H-350 (A)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 550 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the H-350 (A) 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 Hürlimann H-350 (A) is newer: production began 14 years later. We hold no parts-availability data, so there is no call on parts.
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- 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 difference is under the 10% threshold, too small to call.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the 550 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the H-350 (A) 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 550 (DT): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Fiat 550/550 DT”); the H-350 (A): lift through the full range at the hitch ends, as stated by the source (Traktorenlexikon, “Hürlimann H 350 (A)”) — 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.
