Farmall 400 vs Farmall Super MD

Verdict: Farmall 400 vs Farmall Super MD

The Farmall 400 and the Farmall Super MD are both tractors — here is how they stack up on the figures that matter. Farmall Super MD leads on rated power with 48 hp against 45 hp. Farmall 400 is the lighter machine (2,857 kg vs 5,725 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Farmall 400 is the newer design (1954 vs 1952). In short: choose the Farmall Super MD for outright pulling power, or the Farmall 400 if a tighter budget and lighter footprint matter more.
