Caterpillar 446D vs Caterpillar 450E
Verdict: Caterpillar 446D vs Caterpillar 450E
The Caterpillar 446D and the Caterpillar 450E are both backhoe loaders — here is how they stack up on the figures that matter. Caterpillar 450E leads on rated power with 137 hp against 110 hp. Caterpillar 446D is the lighter machine (8,920 kg vs 24,141 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Caterpillar 450E is the newer design (2007 vs 2004). In short: choose the Caterpillar 450E for outright pulling power, or the Caterpillar 446D if a tighter budget and lighter footprint matter more.
