How to remove an old gas tank from a John Deere LA115 Riding Lawn Mower

This morning we ventured over to my parents house to help them replace a leaking gas tank from our old mower. We were gifted this mower from our in-laws when we were living in Washington. We had an acre to mow, and they just purchased a new mower for their property. When we moved to Arizona, we brought the mower with us, ,in case we ended up in a place that had grass. Well, we did not. So we left it at my parents house so they could use it on their 1 acre of lawn.

Now all these years later, the mower is still working like a champ, but it has a few problems. You can follow along on our adventure on your Youtube video for How to remove a gas tank from a John Deere LA115 riding lawn mower here:
