The quick coupler is used to quickly change work tools while the operator remains in the cab. The quick coupler can be used with a broad range of buckets and work tools. The work tools are held onto the quick coupler by hydraulic pressure. A blocking bar locks the work tools to the quick coupler. A lifting eye is included on the quick coupler in order to pick up loads.
