The LAN390985 is a 2400 Series, 1_" hex yoke with locking ball quick coupler connection, used to adapt a John Deere® head to a Case IH® combine. The yoke connects to the cross bearing and attaches to the hex shaft.
Simply remove the combine side yoke from the drive shaft already on the head, and install the LAN390985 to connect the drive shaft to the hex shaft drives on Case IH® combine feeder houses.
The yoke will fit any Lankota drive shaft.
