Backshaft Speed

Adjusting Backshaft Speed allows you to optimize the feed rate of the header to the travel speed and volume of material the machine is harvesting.

Modify When:

Increase Backshaft Speed When:

• Flagging of stalk.
• Pulling stalk out of the ground.
• Higher backshaft speeds are recommended for faster harvesting speeds and taking in large volumes of material to reduce loading on drive components.

Decrease Backshaft Speed When:

• Snapping off stalk and ingesting into separator.
• Butt shelling because ear hits deck plate too fast.
• Reducing the Backshaft Speed can reduce ears bouncing and the generation of free grain in the header when harvesting lower volumes of material.
