Harvesting machine, especially a self-propelled pick-up chopper

摘要

The invention relates to a harvesting machine, especially a self-propelled pick-up chopper for picking up and chopping corn, wilted grass, green feed and similar harvested material, with a chopper device disposed after pick-up and feed organs. The chopper device comprises a chopper drum (1) with cutting tools (3) disposed in the circumferential direction of the chopper drum (1) at a distance from one another. In order to be able to make available a harvesting machine with an advantageous vibrational behavior and lower power requirements, the cutting tools (3) are constructed with an overlapping dimension "U" with respect to the cutting tools disposed ahead and behind in the circumferential direction.
