Aspects of the present disclosure relate to display structures for displaying the wear status of reducing elements (e.g., chisels, teeth, etc.) on a reducing component. In certain examples, the display structure can include a matrix that visually depicts all of the reducing elements of the reducing component in a row and column format. The wear status of the reducing elements can be indicated by techniques such as different colors, different numbers, different letters, shapes, bar codes etc. Another aspect of the present disclosure relates to an autonomous system where a remote party can simultaneously monitor the wear status of the reducing elements of multiple machines on the display structure. For each machine, the remote party (e.g., operator, supply source, supervisor, and main office) can each receive a wireless signal indicating when the reducing elements are approaching a need for replacement.
