Fully compliant to Tier III engine regulations, the new machines also have been redesigned for increased visibility and power. The C-Series (Circle 906) features a new tough and sturdy lightweight attachment, a new structural concept and upper design, as well as a larger and more comfortable cab. Four different undercarriages are available to ensure the proper configuration for the application.
