with my fence situation, I'm actually looking for a flail type machine; If I could find a Matthews Co. "Lawn Genie" in either a 4' or 5' version, I'd be real happy. I can still get virtually all the parts for those, M.C. has forever been super on parts for their machines, and if it's not in stock, they will fab it from the print archives. I was part of the design crew on the 4' version, and it's a tank. Extremely over-built & durable, it could withstand a 35 hp input !
A Brush Hog is an excellent machine, but I need manuverability in my situation, a long tail swing won't get it.
