Challenger MT455 vs Challenger MT455B

Verdict: Challenger MT455 vs Challenger MT455B

The Challenger MT455 and the Challenger MT455B are both tractors — here is how they stack up on the figures that matter. Challenger MT455B leads on rated power with 80 hp against 75 hp. Challenger MT455 is the lighter machine (6,211 kg vs 8,885 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Challenger MT455B holds more fuel (151.4 L vs 110.1 L) for longer stints between fills. Challenger MT455B is the newer design (2004 vs 2002). In short: choose the Challenger MT455B for outright pulling power, or the Challenger MT455 if a tighter budget and lighter footprint matter more.
