Amen to the top link from Brian. I'm kind of out of the tractor business for a few weeks recovering from bypass surgery. I hired my out of work neighbor who does tractor work as part of his normal job. He took off my 6' BB and is using his 7" BB on my tractor, which has the top link. He is loving the control it gives him, as well as how easy it makes adjusting the Brush Hog.
Sorry to hear of your health problems Doug and hoping for a quick recovery.
