Ford 8670 vs Ford TW-15

Verdict: Ford 8670 vs Ford TW-15

The Ford 8670 and the Ford TW-15 are both tractors — here is how they stack up on the figures that matter. Ford 8670 leads on rated power with 148 hp against 140 hp. Ford TW-15 is the lighter machine (11,355 kg vs 15,800 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
