Abstract
A chopping drum for a forage harvester has a shaft. Supporting rings are mounted on the shaft one next to the other in the axial direction and extending in the radial direction. Blade holders are distributed around the outer periphery of the supporting rings, and chopping blades are mounted on the blade holders by first screws. The first screws produce a connection between blade holders one following the other in the peripheral direction.
