How do I bypass the DRM

Here's the write-up's Kyle wrote a year ago here on the subject:

• Wired - We Can’t Let John Deere Destroy the Very Idea of Ownership
• IFIXIT - John Deere Responds to Copyright Mess It Made

The good news here, there is a three year stay on DRM for repairing automobiles and agricultural vehicles and machinery equipment!

Here's the full document: Copyright Ruling. To get to the section search for this: Proposed Class 21: Vehicle Software – Diagnosis, Repair or Modification

I would recommend you review the agricultural trade rags as I'm sure you can find a device for sale that will allow you access to the repair codes like cars have.
