Fiat 400 vs Fiat 431R
Verdict: Fiat 400 vs Fiat 431R
The Fiat 400 and the Fiat 431R are both tractors — here is how they stack up on the figures that matter. Fiat 431R leads on rated power with 40 hp against 38 hp. Fiat 431R is the lighter machine (1,519 kg vs 3,750 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
