Challenger MT655C vs Challenger MT745

Verdict: Challenger MT655C vs Challenger MT745

The Challenger MT655C and the Challenger MT745 are both tractors — here is how they stack up on the figures that matter. Challenger MT655C leads on rated power with 265 hp against 255 hp. Challenger MT745 is the lighter machine (12,789 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 MT655C holds more fuel (590.1 L vs 446.6 L) for longer stints between fills. Challenger MT655C is the newer design (2009 vs 2002). In short: choose the Challenger MT655C for outright pulling power, or the Challenger MT745 if a tighter budget and lighter footprint matter more.
