If you don't want to buy Deere's hardware and subscriptions but you still want to use My JohnDeere Operations center to view your data either on the web based site or on the app with your phone or tablet you do the following things:

1. Stick an empty USB into your JD 2630 or JD 2600 (or 4xxx, not familiar with those though so maybe different?)

2. Transfer data to the USB drive

3. Create a My JohnDeere account

4. Download and install the JohnDeere Data Manager on a Windows computer

5. Use the JohnDeere Data Manager to upload the data from the USB drive into the cloud

6. Access your data in the My John Deere Operations center either through the web based application or through the app on your phone or tablet

Like gpsdude said, don't delete the data that you have on the USB drive. Store it safely and organized on your hard drive in case you need it at a later date.
