Ford 8670 vs Ford TW-20
Verdict: Ford 8670 vs Ford TW-20
The Ford 8670 and the Ford TW-20 are both tractors — here is how they stack up on the figures that matter. Ford TW-20 leads on rated power with 157 hp against 148 hp. Ford TW-20 is the lighter machine (12,250 kg vs 15,800 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Ford 8670 is the newer design (1993 vs 1979). In short: choose the Ford TW-20 for outright pulling power, or the Ford 8670 if a tighter budget and lighter footprint matter more.
