Abstract

A drive system for self-propelling harvester is disclosed. The harvester includes a drive motor, a transfer case driven by the drive motor and having an output pulley arranged on a driveshaft of the transfer case and driving, using a main drive belt, at least one main pulley of a rotating cutter drum arranged on the end of a cutter drum shaft, a conditioning apparatus, an ejection accelerator, and a hydraulic pump for hydraulically driving an attachment and/or a feed device. The output pulley, the main drive belt and the main pulley form a main drivetrain for driving the cutter drum, the conditioning apparatus, and the ejection accelerator, and the attachment and the feed device are each driven by a separate drivetrain. At least one prop shaft, on the side of the main drivetrain, is arranged or positioned to lie in a common vertical plane with the main drive belt.
