Hello, Nuprules! Welcome to the Xfinity Forums. I'm glad you reached out to us for help getting that line buried. It sounds like it has been there for far too long and I can absolutely help get it out of your way for mowing.
I would also like a quick second to let you and anyone viewing know that sending unsolicited PM's to anyone here on the forums is a violation of our guidelines. We always encourage customers to make a post requesting help and wait for an invitation to PM someone before doing so. This helps us keep everything organized and ensures that everyone is assisted in the order they reach out. As long as you remember for the future, its no big deal! 🙂
Regardless, I've replied to your PM and I look forward to your response.
