Challenger 85D vs Challenger MT945B

Verdict: Challenger 85D vs Challenger MT945B

The Challenger 85D and the Challenger MT945B are both tractors — here is how they stack up on the figures that matter. Challenger 85D leads on rated power with 370 hp against 363 hp. Challenger 85D is the lighter machine (15,528 kg vs 17,811 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
