Cat 446 expert review
:quality(50)/60952/a25e1d76-5098-4ef7-a6f5-fe8bc1dffd1a.jpeg)
Overview
The Cat 446 sits at the upper end of Caterpillar’s older backhoe lineup, designed for operators who need big power, longer reach, and higher lift. With 76.81 kW of gross power, 5.24 m digging depth, and about 5,445 kg of breakout force, it supports deep trenching and bulk excavation with strong stability.
Pros Strong breakout and lift, excellent digging reach, heavy chassis provides solid stability.
Cons Large footprint on confined sites, older platform with limited operator refinement.
Efficiency
A 2.71 m loader dump height supports truck loading, while the 4.91 m extended backhoe dump height improves spoil placement. Higher weight and power help maintain steady cycles in compacted soils.
In Cabin
The cab is rugged and straightforward with predictable controls. Comfort and noise isolation reflect its older-generation design.
In Comparison
Compared with the Cat 442, the 446 emphasizes lift and reach. Against the Cat 444, it leans more toward chassis stability and heavy lifting.
Final Verdict
Rated 4 stars, the Cat 446 suits contractors prioritizing lift capacity, reach, and raw digging power, priced between AED 158,000 and 437,000.
