ABSTRACT:
A multipurpose bucket for a front end loader is provided. The multipurpose bucket includes a second frame rotatably connected to a first frame to provide a pincer configuration and a scooping configuration. The first frame includes a bottom of the rear bucket wall; a pair of rear side walls with a plurality of pincer teeth; and a plurality of support arms extending from the rear bucket wall. The second frame includes a bucket floor having a pincer end and a scraper end; a pair of circular front side walls extending from the bucket floor to the pivot point, which increases the volume of the bucket and reduces spills; a plurality of pincer teeth extending from the pincer end of the front side walls; a rear plate extending from each of the pivots, attached to the front side walls, which forms the top of the rear bucket wall which increases the volume of the bucket; and a scraper blade extending from the scraper end of the bucket floor. The two frames are joined by the pivot as well as by at least one hydraulic cylinder. A method of operating the bucket is provided. Also included is a non-multipurpose bucket with rounded sides to increase volume and reduce spills.
