Challenger 70C vs Challenger MT645D

Verdict: Challenger 70C vs Challenger MT645D

The Challenger 70C and the Challenger MT645D are both tractors — here is how they stack up on the figures that matter. Challenger 70C leads on rated power with 250 hp against 240 hp. Challenger MT645D is the lighter machine (10,999 kg vs 16,186 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Challenger MT645D is the newer design (2011 vs 1995). In short: choose the Challenger 70C for outright pulling power, or the Challenger MT645D if a tighter budget and lighter footprint matter more.
