Abstract
A blade assembly for a waste reduction machine includes a hub which is mounted on a rotatable shaft. A plurality of attachment devices are located at spaced-apart intervals on the periphery of the hub. Each attachment device has a tooth releasably attached to it. The attachment device includes an elongate threaded element which is oriented generally perpendicular to a radial line on the hub which intersects the threaded element. The threaded element engages the tooth and pulls it onto or pushes it off of the attachment device. The attachment device includes an elongate locking element and the tooth includes a slot which slidingly interfits onto the locking element. The locking element and slot are configured so as to prevent the tooth from moving radially outwardly from the periphery of the hub.
