Abstract
A chopper arrangement for a harvesting machine comprises a body that is rotated in a predominantly vertical axis of rotation. The body is provided with a plurality of radially extending knives that are axially distributed along the body. The knives have radially outer ends that are arranged in a conical shape. In this way the knives at the first end having a smallest radial extension are rotated at a slower circumferential speed than knives having a larger radial extension.
