Challenger MT655C vs Challenger MT745B

Verdict: Challenger MT655C vs Challenger MT745B

The Challenger MT655C and the Challenger MT745B are both tractors — here is how they stack up on the figures that matter. Challenger MT745B leads on rated power with 269 hp against 265 hp. Challenger MT745B is the lighter machine (14,095 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 2005). In short: choose the Challenger MT745B for outright pulling power, or the Challenger MT655C if a tighter budget and lighter footprint matter more.
