Overview
This is a diagnostic how-to, not a review: on a John Deere 4700 with a bucket that droops overnight despite no visible external leaks, the presenter swaps the lift and bucket hoses at the valve, then re-tests over several hours to isolate whether the internal leak is in the control valve or the bucket cylinders. Useful for owners troubleshooting drooping loader attachments before deciding what to rebuild.
