Overview

Increase grain in the tank with a two-speed center feed section. A slow-speed setting softens the impact of crop fingers and drum flighting when engaging with crop. This ensures that easy-shelling crops like lentils and soybeans do not get thrown over the feeder house. Use the high-speed setting in canola or high-yielding cereals to prevent slug feeding while ensuring that the drum does not plug.

Benefits

Experience less downtime during harvest related to unplugging the header, which allows for more harvesting time at the highest productivity levels.
Higher feed drum torque is matched to the capacity of the combine to ensure optimal feed rates into the combine. Higher torque on the front feed drum allows operators to confidently harvest tough feeding crops like canola.
Additionally, prevent underfeeding in light crops with the center crop flow divider. When not harvesting crop with the full width of the draper, the center crop flow divider prevents crop from skipping over the center feed section and going on the opposite draper belt.

Additional details

The two-speed center feed section maintains a consistent ratio between the feed drum and center feed belt speed.
Change center feed section speed with a toolless, two-speed, easy-shift handle on the gearcase to the left of the draper feeder house opening.
