Challenger MT665E vs Challenger MT745B

Verdict: Challenger MT665E vs Challenger MT745B

The Challenger MT665E 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 264 hp. Challenger MT665E is the lighter machine (10,800 kg vs 14,095 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Challenger MT665E holds more fuel (628.3 L vs 446.6 L) for longer stints between fills. Challenger MT665E is the newer design (2014 vs 2005).
