Fiat 400E vs Fiat 45-66S
Verdict: Fiat 400E vs Fiat 45-66S
The Fiat 400E and the Fiat 45-66S are both tractors — here is how they stack up on the figures that matter. Fiat 400E leads on rated power with 45 hp against 44 hp. Fiat 400E is the lighter machine (3,671 kg vs 4,685 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Fiat 45-66S is the newer design (1992 vs 1974). In short: choose the Fiat 400E for outright pulling power, or the Fiat 45-66S if a tighter budget and lighter footprint matter more.
