Challenger MT285B vs Challenger MT425

Verdict: Challenger MT285B vs Challenger MT425

The Challenger MT285B and the Challenger MT425 are both tractors — here is how they stack up on the figures that matter. Challenger MT425 leads on rated power with 55 hp against 48 hp. Challenger MT285B is the lighter machine (1,660 kg vs 6,182 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
