Fiat 513R vs Fiat 55-66

Verdict: Fiat 513R vs Fiat 55-66

The Fiat 513R and the Fiat 55-66 are both tractors — here is how they stack up on the figures that matter. Fiat 513R leads on rated power with 55 hp against 54 hp. Fiat 513R is the lighter machine (2,530 kg vs 2,925 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
