Dual Roll Earlage Adapter to fit John Deere® (8000 & 9000 series)

Product Description:

The K9000 Dual Roll Adapter features an improved crop flow system with the addition of an extra intake roller on the bottom. Combined with the standard top intake roller, this adapter is specially designed for today's higher horsepower harvesters and larger corn heads, providing better cleanout and increased harvesting speed, averaging 6-7 MPH.

The K9000 is used for harvesting just the ears of corn using the row crop header to make earlage. Earlage is harvested later than silage, giving the producer a longer working window, and it provides a product that reduces the amount of roughage that needs to be fed compared to a corn-based ration. This dual roll adapter is highly recommended for operations exceeding 300 acres of earlage, providing consistent performance and durability.

These adapters are known for their robustness, with many customers experiencing over 10 years of use. Typically, replacement occurs when a customer trades brands or upgrades their harvester.

This adapter is specifically made for John Deere® 8000 and 9000 series self-propelled forage harvesters. It facilitates the connection between the harvester and a row-crop header, making the transition from silage harvesting to earlage harvesting simple. Installation is the same as hooking up any other implement, and the adapter can be left on the harvester or corn head when not in use. When left on the corn head, simply lift the adapter/corn head and hook up the PTOs.

Key Installation & Operational Notes:

• Use the K9000KIT or K8000KIT to block up the feed rolls, optimizing performance during operation.
• Highly recommend using bottom earlage pans to make the feed roll chamber like a tunnel, ensuring smooth and consistent crop flow.
• You will need to remove the quick coupler from the forage harvester and use the K8000DL to drive the earlage adapter, providing a more efficient feeding angle of the corn head. 

Installation of the K9000 Earlage Adapter is as simple as hooking up any other implement. You can leave the adapter on the harvester or corn head when not in use. When leaving the adapter on the corn head, simply pick up the adapter/corn head and hook up the PTOs.

Measuring Your PTO Connection:

To ensure proper compatibility, measure the Hex shaft on your corn head by removing the PTO where it connects to the frame. Common sizes include:

• 1-1/8”
• 1-1/4”
• 1-1/2”

Patent # 10,743,467 and patent # 8,376,126

If you want to use the header height control in your harvester, you will need our K31-EXT Header Height Control Extension Cord.

WARNING:  Grinding earlage with the use of corn heads and choppers can cause a risk of fire.  The risk of fire does not emanate from the adapter products described here, but can be caused by the heat generated by the choppers.  To reduce the risk of fire, please keep the chopper clear of dust.
