Challenger 70C vs Challenger MT665B

Verdict: Challenger 70C vs Challenger MT665B

The Challenger 70C and the Challenger MT665B are both tractors — here is how they stack up on the figures that matter. Challenger 70C leads on rated power with 250 hp against 246 hp. Challenger 70C is the lighter machine (16,186 kg vs 19,550 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Challenger MT665B is the newer design (2005 vs 1995). In short: choose the Challenger 70C for outright pulling power, or the Challenger MT665B if a tighter budget and lighter footprint matter more.
