ABSTRACT:
An excavator provides a frame that includes an undercarriage having a ground engaging propeller (e.g. endless tracks) that enables the undercarriage to move the frame. The frame includes an upper portion that supports an elongated articulating boom having at least two boom sections that are pivotally connected. The frame provides an enclosure having a motor drive and a hydraulic system that powers the boom, and a cab rotatable upon the undercarriage about a generally vertical axis. The boom has a distal end with a bucket that has one or more bucket teeth. A scraper is connected to the boom distal end and provides another end that is extendable to a position generally below the cab and to the vertical axis. A connection joins the boom distal end to the scraper. The connection includes a connection of the bucket to the proximal end of the scraper and to the upper surface of the scraper wherein the bucket tooth connects to the scraper.
