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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
