A quick-attach coupler for attaching an implement such as a bucket (15) to a machine such as a front end loader or backhoe. The coupler includes attachment means (25, 29) for attaching the coupler to the machine, upper receiving means (20) for receiving an upper coupling means (18) on the implement and lower receiving means (19) for receiving a lower coupling means (17) on the implement. The lower receiving means has an opening including a locating formation in the form of a threshold (19a) which retains the lower coupling means (17) in the lower receiving means, and latch means (34) associated with the upper receiving means (20) retain the upper coupling means (18) within the upper receiving means (20) and prevent the lower coupling means (17) disengaging the locating formation (19a) of the lower receiving means thus maintaining the attachment of the implement on the coupler. The latch means may be manually operated or remotely operated by pneumatic, hydraulic or electrically operated actuators (69, 75). |
