Caterpillar D3 vs Caterpillar D3K

Verdict: Caterpillar D3 vs Caterpillar D3K

The Caterpillar D3 and the Caterpillar D3K are both industrial tractors — here is how they stack up on the figures that matter. Caterpillar D3K leads on rated power with 74 hp against 62 hp. Caterpillar D3 is the lighter machine (10,300 kg vs 17,185 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Caterpillar D3K is the newer design (2007 vs 1972). In short: choose the Caterpillar D3K for outright pulling power, or the Caterpillar D3 if a tighter budget and lighter footprint matter more.
