Abstract: A fatigue life optimized modular bucket assembly for a work machine and a method of manufacturing thereof are disclosed. The bucket assembly includes a bucket core having a pair of side sections, a continuous wrapper, a supporting element, and a receptacle; and an extension module having a pair of side bars, a guard module, an edge module, and, optionally, a set of extension plates. The method includes prebuilding the bucket core, receiving an order, providing parts for the extension module, and assembling the bucket core and the extension module parts. The bucket assembly may include universal and customizable components without exhibiting reduction to fatigue life commonly associated with weld seams.

Abstract: An implement system includes a linkage and a bucket coupled with the linkage and movable between a dump position and a racked position. The bucket has a compound back section that forms a profile having a basin shape to assist in distributing material within the back section when the bucket is curled, and nesting the bucket close to the linkage. Related methodology is disclosed.
