Abstract
An attaching and release mechanism is provided for coupling a material handling bucket to the free end of a scoop arm extending from a loader or backhoe. A universal bucket mounting linkage is pivotally mounted to the loader scoop arm and readily receives various types and sizes of buckets. The bucket mounting linkage has a four-bar configuration with hook portions adapted for engagement with mating projections on the bucket. Over-center linkage, pivotally attached to one end of the bucket mounting linkage, provides locking engagement or disengagement between the hook portions and the mating projections on the bucket. To latch the bucket on the loader scoop arm, the hook portions and over-center linkage are aligned with the complementary mounting structure on the bucket, and the over-center linkage is pushed over-center which causes the bucket mounting linkage to lock against the mounting structure on the bucket to thereby couple the bucket and loader scoop arm.
