Changing Feeder Conveyor Speed

NOTE: The variable speed feeder house changes the speed of the lower feederhouse shaft. The variable speed adjustment is for use with a corn head or row crop head. When using a platform, the variable drive must be slowed all the way down to prevent rapid wear to cutterbar parts.

The feeder conveyor chain can be set to two different speeds by selecting the drive sprocket on the right hand side of the lower shaft.

The feeder house is shipped from the factory with the right hand drive chain on the large sprocket (A).

NOTE: If you have low feed rate conditions, you can decrease the conveyor speed and improve part life by moving the conveyor chain to the small sprocket.

If you have material handling or crop damage problems increase the speed of the conveyor chain by moving it to the large sprocket.

To move the chain to the smaller sprocket:

Open front shields.

Loosen nut (A) and push sprocket rearward.

Loosen nut (B) and move sprocket to upper position
