Challenger MT685D vs Challenger MT755E

Verdict: Challenger MT685D vs Challenger MT755E

The Challenger MT685D and the Challenger MT755E are both tractors — here is how they stack up on the figures that matter. Challenger MT755E leads on rated power with 350 hp against 340 hp. Challenger MT685D is the lighter machine (10,999 kg vs 13,667 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Challenger MT755E holds more fuel (658.6 L vs 632.2 L) for longer stints between fills. Challenger MT755E is the newer design (2014 vs 2011). In short: choose the Challenger MT755E for outright pulling power, or the Challenger MT685D if a tighter budget and lighter footprint matter more.
