Key Specs
The Cat® 903D is compact, yet powerful, delivering high performance with outstanding versatility. A 25% increase in lift capacity and travel speed will allow the operator to be more productive, while new optional features such as engine and ground speed control, provides customizable control when running hydro-mechanical work tools. With a more ergonomic cab, new multi-function joystick, and optional ride control, the 903D allows the operator to enjoy all day comfort.
