I run a 140 in my front yard, ya it's an acre and dangit I have to share that with a Hedge Tree. A 60 foot diameter, rotten, drops about a hundred apples each fall, Hedge tree. It'd be fine if it would stretch to the south BUT I have this circle on the North side, so, it keeps stretchin. I know that's just 30 feet less in radius but it is a rather large chunk. I tend to pivot on the opposite side of center just so it doesn't just reach out and touch me, again.
