ABSTRACT:
An improved mounting arrangement for a knife to a disc for use on a rotary disc cutter that eliminates the need for a threaded connector and the associated nut is disclosed. It also provides a positive retention method on the top side of the disc. In addition, it provides a method of removing the knife from the disc without the use of wrenches, simply requiring a tool for prying, such as a screw driver. A further feature is a low profile retainer that does not need to be protected by a wear protector.
