Abstract
A bucket arrangement for an earthworking machine is provided with a cutting edge plate which is bowed outwardly and has a serrated leading edge such that a center tooth assembly is disposed in a plane of engagement with the soil ahead of and below the plane of engagement of a pair of side tooth assemblies. Thus, the center tooth makes penetrating engagement with the soil prior to the side teeth, providing the bucket arrangement with greater penetrating ability. The ability of the bucket to cut or slice through the soil is also enhanced by the serrated portions of the cutting edge plate.
