FLYWHEEL FOR TIMED KNIFE DRIVE

摘要

A cutter bar drive system for a draper header has a cutter bar disposed at a leading edge of the header to cut crop. A cutter bar gear box in operative engagement with the cutter bar is mounted on a forward portion of the header with a drive train mounted on the header to drive the gear box and cutter bar. An external flywheel is mounted along the drive train remote from the gear box and is engaged with the drive train to reduce vibration in the cutter bar and gear box from a remote, external position.
