Challenger MT655D vs Challenger MT745

Verdict: Challenger MT655D vs Challenger MT745

The Challenger MT655D and the Challenger MT745 are both tractors — here is how they stack up on the figures that matter. Challenger MT655D leads on rated power with 265 hp against 255 hp. Challenger MT655D is the lighter machine (10,999 kg vs 12,789 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Challenger MT655D holds more fuel (632.2 L vs 446.6 L) for longer stints between fills. Challenger MT655D is the newer design (2011 vs 2002). In short: choose the Challenger MT655D for outright pulling power, or the Challenger MT745 if a tighter budget and lighter footprint matter more.
