Fiat 45-66S vs Fiat 455C
Verdict: Fiat 45-66S vs Fiat 455C
The Fiat 45-66S and the Fiat 455C are both tractors — here is how they stack up on the figures that matter. Fiat 455C leads on rated power with 47 hp against 44 hp. Fiat 455C is the lighter machine (2,315 kg vs 4,685 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Fiat 45-66S is the newer design (1992 vs 1970). In short: choose the Fiat 455C for outright pulling power, or the Fiat 45-66S if a tighter budget and lighter footprint matter more.
