Have a friend who recently purchased 10 acres of land and about 8 of it is all overgrown grass and light brush. Was farm land until a few years ago. He asked if I could run my flail mower around and knock it all down for him. Wondering how much time you think that would take and what a fair price to charge him is. Have a B2601 with a 53" Betstco mower. Could grab a 6' brush mower from another friend, but don't want to borrow equipment if I don't have to. It is relatively flat and nothin larger than about 1" on it. Mostly about 2' tall grass.
