Abstract
A quick coupler includes mounting structure for mounting the coupler to a machine, and for mounting the coupler to an implement. The mounting structure on the coupler includes wedge coupling surfaces and a tube. The mounting structure on the implement includes hooks for engaging the tube, and complementary wedge coupling surfaces. The wedge coupling surfaces wedge together during coupling to produce and tight fit and solid hold between the coupler and implement. The mounting structure is robust, and can accommodate future possible wear. The kinematic impact on the performance of the implement due to the use of the quick coupler is minimized.
