Fiat 400E vs Fiat 45-66

Verdict: Fiat 400E vs Fiat 45-66

The Fiat 400E and the Fiat 45-66 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 4,255 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Fiat 400E holds more fuel (74.9 L vs 42.0 L) for longer stints between fills. Fiat 45-66 is the newer design (1985 vs 1974). In short: choose the Fiat 400E for outright pulling power, or the Fiat 45-66 if a tighter budget and lighter footprint matter more. Compare the full spec tables below before booking a demo.
