Features
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 feederhouse. 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 will allow 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 will allow 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 feederhouse opening.

![Feed drum controls and slip clutch](https://salesmanual.deere.com/sales/salesmanual/images/NA/combines_headers/hd/slip_clutch_260x205.jpg)
Benefits
- In some crop conditions, the crop can hesitate at the corners of the feed drum, and the retractable drum fingers keep the crop moving into the combine.
- Increase uptime through a high-wear life and durable stainless-steel feed floor.
- The dual-position drums allow the operator to select an upper or lower setting of the drum, creating the gap of a 40.6-cm (16-in.) drum and a 35.6-cm (14-in) drum, respectively.
Additional details
- The feed drum can be positioned in the lower position, creating the traditional feeding gap, or can be raised to the upper position, increasing the feeding gap by 2.54-cm (1-in.), the equivalent of a 35.6-cm (14-in.) feed drum gap.
- For bushy crops, such as canola, put the drum in the upper position.
- RDF feed drum slip-clutch torque is 1600 Nm (1180 lb-ft).

Overview
Help bushy crops, especially heavy canola, feed evenly into the feederhouse with an optional 45.7-cm (18-in.) top auger extending the full width of the draper.
![RDF top auger](https://salesmanual.deere.com/sales/salesmanual/images/NA/combines_headers/hd/rdf_top_auger_450x327.jpg)
Benefits
- With the crop tucked under the auger, the handoff to the center feed drum enables smooth and consistent feeding to the combine to ensure constant load.
- Achieve smooth headfirst feeding when auger speeds are running slightly faster than the belt speed.
Additional details
- This optional 45.7-cm (18-in.) hydraulically driven top auger has an easy speed adjustment at the right side of the platform.
- It is recommended for operation in bushy or high-volume harvesting conditions such as canola.
- Augers can be turned off for crops like lentils or wheat where they are not recommended.

Overview
![Center section seal kit](httpss://salesmanual.deere.com/sales/salesmanual/images/NA/combines_headers/hd/center_sec_seal_kit_450x300.jpg)
Minimize grain loss when straight cutting canola, oil seed, lentils, and peas with a center section seal kit.
Benefits
Save $330 USD ($465 CAD) a year across 607 ha (1,500 acres) by reducing canola center section losses up to 45 percent with a center section seal kit. Maximize performance in straight-cut canola by pairing the center section seal kit with top augers.
Additional details
In crops other than canola, oil seed, lentils, and peas (mainly wheat), there is an increased risk of side belt underfeeding pending conditions.
