Abstract
A quick connect system for attaching excavator buckets and other tools to the arm of a hydraulic excavator. The excavator bucket has a first and second mounting plate connected thereto in a spaced parallel relationship. Each mounting plate has a front and rear mounting assembly aligned to receive the front and rear pins respectively of the arm of the hydraulic excavator. Each mounting assembly has a "U" shaped opening formed therein for receiving one end of one of the respective front and rear pins. A pair of locking pads are mounted to the exterior side of each of the mounting assemblies. One end of each of the front and rear pins has a locking head fixed thereto which is adapted to engage one of the locking pads. A pair of retaining clamps receive the other end of each of the front and rear pins after they are positioned within the "U" shaped opening of the mounting assembly. The retaining clamps secure the other ends of each pin to the mounting assembly.
