Fiat 666 vs Fiat 80-76
Verdict: Fiat 666 vs Fiat 80-76
The Fiat 666 and the Fiat 80-76 are both tractors — here is how they stack up on the figures that matter. Fiat 80-76 leads on rated power with 70 hp against 68 hp. Fiat 80-76 is the lighter machine (4,806 kg vs 6,700 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
