Abstract
A retention system for retaining a milling drum to a driveshaft of a milling assembly. The driveshaft is powered to drive the milling drum about an axis. The retention system includes a retention member coupled to the driveshaft between a first position and a second position. In the first position, the retention member restricts a disengagement between an engagement surface of the driveshaft and a mating surface of the milling drum, inhibiting a release of the milling drum from the driveshaft along the axis. In the second position, the retention member provides clearance for the disengagement of the engagement surface and the mating surface, facilitating the release of the milling drum from the driveshaft along the axis.
