Farmall BN vs Farmall Super A
Verdict: Farmall BN vs Farmall Super A
The Farmall BN and the Farmall Super A are both tractors — here is how they stack up on the figures that matter. Farmall BN leads on rated power with 17 hp against 16 hp. Farmall BN is the lighter machine (816 kg vs 1,088 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Farmall Super A is the newer design (1947 vs 1940). In short: choose the Farmall BN for outright pulling power, or the Farmall Super A if a tighter budget and lighter footprint matter more.
