Challenger MT545 vs Challenger MT545B

Verdict: Challenger MT545 vs Challenger MT545B

The Challenger MT545 and the Challenger MT545B are both tractors — here is how they stack up on the figures that matter. Challenger MT545 leads on rated power with 121 hp against 116 hp. Challenger MT545 is the lighter machine (10,082 kg vs 11,052 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Challenger MT545B holds more fuel (268.8 L vs 224.8 L) for longer stints between fills. Challenger MT545B is the newer design (2004 vs 2002). In short: choose the Challenger MT545 for outright pulling power, or the Challenger MT545B if a tighter budget and lighter footprint matter more.
