Farmall 100 vs Farmall H

Verdict: Farmall 100 vs Farmall H

The Farmall 100 and the Farmall H are both tractors — here is how they stack up on the figures that matter. Farmall H leads on rated power with 19 hp against 18 hp. Farmall H is the lighter machine (1,757 kg vs 2,600 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
