Pilot Operated Controls

Optional pilot operated joystick controls add excavator technology and ease of operation to the 446D. Low effort controls are easy to use, reduce operator fatigue and increase efficiency.


Loader Performance

The loader delivers maximum lift and breakout forces, fast cycle times and high lift capacity.


Backhoe Performance

Superior bucket rotation and forces, an excavator-style backhoe boom and an optional extendible stick combine for high productivity levels.


Work Tools

A wide range of rugged Caterpillar Work Tools are available to meet the needs of your job site applications.


Power Train

Cat 3114 DIT engine is designed to meet demanding 446D requirements.


Hydraulics

Our closed-center, variable displacement, load-sensing hydraulic system provides high power where you need it, when you need it.


Operator Station

The 446D operator environment is ergonomically designed to create a comfortable work area with easy-to-use machine controls that reduce operator fatigue, increase efficiency and productivity.


Additional Features

Other benefits contribute to 446D efficiency and productivity.
