How do you change a billhook on a John Deere 14T baler?

To change the billhook on a JOHN DEERe 14T baler, first ensure the baler is powered off and disconnected from any tractor. Remove the access cover to expose the billhook assembly and unscrew the retaining bolts that hold the old billhook in place. Carefully lift out the old billhook and replace it with the new one, securing it with the bolts. Finally, reattach the access cover and perform a test run to ensure proper operation.
