Abstract
A quick connect apparatus for connecting a knife to a rotary disc cutterhead comprising a spring-loaded connector and a locking device which, when installed, prevents unintentional release of the knife from the cutterhead. The quick connector with locking device replaces a conventional bolted connection and reduces the time necessary to remove and reinstall a knife on a rotary cutterhead compared to a bolted knife connector while improving knife retention compared to known quick-change knife connection mechanisms.
