Caterpillar D6R vs Caterpillar D7F

Verdict: Caterpillar D6R vs Caterpillar D7F

The Caterpillar D6R and the Caterpillar D7F are both industrial tractors — here is how they stack up on the figures that matter. Caterpillar D7F leads on rated power with 180 hp against 179 hp. Caterpillar D7F is the lighter machine (31,300 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 1969). In short: choose the Caterpillar D7F for outright pulling power, or the Caterpillar D6R if a tighter budget and lighter footprint matter more.
