Challenger 70C vs Challenger MT645C

Verdict: Challenger 70C vs Challenger MT645C

The Challenger 70C and the Challenger MT645C 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 70C is the lighter machine (16,186 kg vs 24,250 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Challenger MT645C is the newer design (2009 vs 1995). In short: choose the Challenger 70C for outright pulling power, or the Challenger MT645C if a tighter budget and lighter footprint matter more.
