Fiat 50-66S vs Fiat 505C

Verdict: Fiat 50-66S vs Fiat 505C

The Fiat 50-66S and the Fiat 505C are both tractors — here is how they stack up on the figures that matter. Fiat 505C leads on rated power with 50 hp against 49 hp. Fiat 50-66S is the lighter machine (4,685 kg vs 5,300 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
