Description

Product Overview
• Part Number: 670478.2
• Part Name: Auger Shaft, Grain Header Auger Shaft
• Main Function: This is the drive shaft for the auger (commonly known as the “bridge” or “screw”) inside the grain header (commonly known as the “header”). It is responsible for evenly distributing the grain delivered by the header reel to the center, and then feeding the crop into the harvester’s bridge through the finger puller mechanism, ultimately entering the threshing system.
