Fiat 446 vs Fiat 50-66S

Verdict: Fiat 446 vs Fiat 50-66S

The Fiat 446 and the Fiat 50-66S are both tractors — here is how they stack up on the figures that matter. Fiat 446 leads on rated power with 50 hp against 49 hp. Fiat 446 is the lighter machine (4,299 kg vs 4,685 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
