Caterpillar D6R vs Caterpillar D7E

Verdict: Caterpillar D6R vs Caterpillar D7E

The Caterpillar D6R and the Caterpillar D7E are both industrial tractors — here is how they stack up on the figures that matter. Caterpillar D6R leads on rated power with 179 hp against 160 hp. Caterpillar D7E is the lighter machine (32,590 kg vs 32,600 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Caterpillar D6R is the newer design (1995 vs 1961). In short: choose the Caterpillar D6R for outright pulling power, or the Caterpillar D7E if a tighter budget and lighter footprint matter more.
