Verdict: Fiat 50-66S vs Fiat 55-88
The Fiat 50-66S and the Fiat 55-88 are both tractors — here is how they stack up on the figures that matter. Fiat 50-66S leads on rated power with 49 hp against 48 hp. Fiat 50-66S is the lighter machine (4,685 kg vs 6,173 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
