Caterpillar D6D vs Caterpillar D6M

Verdict: Caterpillar D6D vs Caterpillar D6M

The Caterpillar D6D and the Caterpillar D6M are both industrial tractors — here is how they stack up on the figures that matter. Caterpillar D6M leads on rated power with 153 hp against 140 hp. Caterpillar D6D is the lighter machine (26,060 kg vs 32,500 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
