Eicher 635 K or Fiat 35-66 (DT)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 635 K has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 35-66 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Fiat 35-66 (DT) suits road haulage better on this data: 18% (4.6 km/h / 2.9 mph) more top speed.
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 Eicher 635 K is 15% heavier (200 kg / 441 lb) than the Fiat 35-66 (DT) (both unladen weight, as stated by the source).
- The Fiat 35-66 (DT) has 45% more forward gears (5 gears) than the Eicher 635 K (both forward gears, as stated by the source).
- The Fiat 35-66 (DT) has 18% more top speed (4.6 km/h / 2.9 mph) than the Eicher 635 K (both top speed forward, as stated by the source).
- The Fiat 35-66 (DT) is available with four-wheel drive; the Eicher 635 K is two-wheel drive (as stated by the sources).
- Even on PTO speeds: the same speeds (540 rpm).
- 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 635 K has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 35-66 (DT) 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 635 K: lift at an unstated point, as stated by the source (Traktorenlexikon, “Eicher 635 K”); the 35-66 (DT): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Fiat 35-66/35-66 DT”) — 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.
