Cutter wheel wear inserts and mounting

A rotatable cutter wheel of a material reduction machine, the cutter wheel comprising:

• a drive plate configured to be mounted on the material reduction machine for rotation in a forward rotation direction about a central axis, wherein the drive plate includes a central driveshaft aperture and an outer peripheral edge;
• first and second wear plates positioned respectively along first and second axial sides of the drive plate and removably coupled to the drive plate;
• a cutter removably coupled for rotation with the drive plate via a fastener;
• and
• a wear insert positioned to cover a portion of the outer peripheral edge of the drive plate, wherein the wear insert is mounted between the first and second wear plates, and
• wherein the fastener that removably couples the cutter to the drive plate also extends through an aperture in the wear insert.
