ABSTRACT:
In earthmoving buckets, and more especially in deep buckets, the heel portion is subjected to excessive wear due to its extended shape rubbing or impinging upon excavation material while engaged in digging operations. The present invention teaches a bucket shape which reduces the wear of the heel portion while retaining bucket capacity by using a multiple radius design to define the shape in profile.
