I have been picking away clearing the brush out in the lower part of the yard for a few years now.  The idea is to use it for hops and a small orchard.  I have it graded about as far as I am going to get with my small tractor and the boxblade mostly because there is little soil and boulders near the surface compliments of the glaciers.  I'm thinking that I am going to rake what is left and then bring in top soil to fill any low spots.  Is there a better way to make it mowable?  I'm pretty sure I would destroy my light duty 3 pt rototiller if I tried it.  I've been told that a Harley rake is the right tool but have never used one.  Anyone used one with a small tractor?
