3.12.2 Auger Operation
Auger Speed
The header is equipped with an auger drive sprocket to match the combine. The auger is chain-driven by a direct
connection to the feeder house, and auger speed depends on the feeder house speed. You can adjust auger
speeds from the combine to suit crop conditions. Contact your Dealer for available sprocket options.
Refer to Auger Drive Sprockets, page 190 for instructions on changing the sprocket.
Checking Auger Position
The auger position is critical for a smooth, high-capacity flow of crop into the feeder house. It is factory-set for
normal crop conditions, but it may require adjustment for different crops and conditions. Check the auger position
prior to operating the pick-up header to ensure the auger rotates freely without touching the auger pan or
stripper bars.
