Challenger MT685C vs Challenger MT755D

Verdict: Challenger MT685C vs Challenger MT755D

The Challenger MT685C and the Challenger MT755D are both tractors — here is how they stack up on the figures that matter. Challenger MT755D leads on rated power with 327 hp against 320 hp. Challenger MT685C is the lighter machine (10,999 kg vs 14,095 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Challenger MT685C holds more fuel (590.1 L vs 412.6 L) for longer stints between fills. Challenger MT755D is the newer design (2012 vs 2009). In short: choose the Challenger MT755D for outright pulling power, or the Challenger MT685C if a tighter budget and lighter footprint matter more.
