The rotatable shaft also includes a first engagement feature formed on the inner surface and a key disposed about the recess. The key is configured to engage an opening of a disc blade to block rotation of the disc blade relative to the rotatable shaft. Furthermore, the disc assembly includes a fastener having a shaft configured to extend through the opening of the disc blade and to engage the recess of the rotatable shaft. The shaft has a second engagement feature configured to engage the first engagement feature to couple the disc blade to the rotatable shaft.
