Fiat 446 vs Fiat 50-66

Verdict: Fiat 446 vs Fiat 50-66

The Fiat 446 and the Fiat 50-66 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 50-66 is the lighter machine (4,255 kg vs 4,299 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
