A RIPPING BUCKET ARRANGEMENT

摘要

Among the variety of bucket arrangements that are commonly available, several are specifically designed for ripping applications in materials that are extremely hard to penetrate. While these types of buckets are normally satisfactory in ripping hard, strong, brittle materials, their designs do not lend themselves to excavating and dumping weaker more plastic materials and thus exhibit little or no versatility. The bucket arrangement of the subject invention includes a first and second ground penetrating means that are selectively positioned on the bucket with respect to each other. The selective positioning allows sole engagement of either of the first or second ground penetrating means with the ground or simultaneous engagement of both penetrating means with the ground. Such an arrangement provides superior operation in a ripping capacity and yet the selective positioning of the first and second penetrating means also permits excellent operation in weaker or plastic materials.
