Caterpillar D5M vs Caterpillar D6K

Verdict: Caterpillar D5M vs Caterpillar D6K

The Caterpillar D5M and the Caterpillar D6K are both industrial tractors — here is how they stack up on the figures that matter. Caterpillar D6K leads on rated power with 125 hp against 121 hp. Caterpillar D5M is the lighter machine (11,702 kg vs 27,802 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Caterpillar D6K is the newer design (2005 vs 1996). In short: choose the Caterpillar D6K for outright pulling power, or the Caterpillar D5M if a tighter budget and lighter footprint matter more.
