An articulated front loader arm structure is provided for use with a conventional refuse collection vehicle having a conventional cab chassis. The articulated arm structure is controlled by a programmed logic controller (PLC) which for monitors and controls the movement of the front loader articulated arm structure. The PLC communicates with various cylinders and sensors to control the extension/retraction of the various cylinders associated with the various arm sections of the front loader arm structure during movement through both its container dump cycle and its container return cycle. The articulated arm structure allows the present front loader arm mechanism to both extend over a conventional cab chassis as well as to be stored on top of the refuse vehicle under the current legal height restriction of 13 feet, 6 inches.
