Abstract
A chipper knife assembly for a stump disintegrator is disclosed in which knife holder bodies radially span across pockets or openings formed in a rotating chipper disk. A reversible and replaceable blade insert with a plurality of selectable carbide edges is carried on the leading face of the holder body and fixed thereon by means of a threaded fastener inserted from the trailing face of the holder body through a hole formed between the trailing face and the leading face. The end of the fastener engages a threaded recess in the blade insert. The chipper knife assembly divides the chipper disk opening into a leading opening through which wood chips and other debris may pass for subsequent discharge and a leading opening which provides clearance and access to the threaded fastener for its removal and installation.
