Abstract
A mower blade spindle assembly includes a drive shaft having a hub received on threaded end of the shaft. The shaft is tapered from the root diameter of the last thread and the hub is correspondingly tapered so as to provide a thread relief. The end of the shaft on which the hub is received has a threaded bore extending axially therein for receiving a blade mounting bolt. The bore is counterbored to a depth corresponding to the length of the threaded portion receiving the hub.
