Abstract
A milling machine for milling a surface of a roadway includes a frame and a milling assembly having a cutter drum that is mounted for rotation with respect to the frame. The cutter drum has a drive shaft on which a sheave is mounted. A primary drum drive assembly is adapted to rotate the cutter drum with respect to the frame. The primary drum drive assembly includes a drive belt that cooperates with the sheave on the drive shaft for the cutter drum to rotate the cutter drum. A belt lift assembly may be operated to selectively disengage the drive belt from the sheave of the drive shaft for the cutter drum.
