For the past few months our high-tech solar-powered clothes dryer has been sticky. We greased the end close to the house, and it seemed to help for a couple of days. Finally we brought the ladder up to check on the end mounted on a tree some ways from the house to grease that end as well. What we found once we got there no amount of greasing could fix: the tree had grown around the anchor, and was now rubbing against the wheel!
Our guess is this clothes line has been set up for at least 17 years, possibly as much as 30 (depending on whether it was the initial owners who set it up, or if it was the owners before us)!
