Any close up pics of your 8' rake? Do you know what rpm the rotor runs at?
The easiest way to smooth a yard is buy a Ferris mower.
I'll tell you how golf courses keep their greens flat is with aeration. They aerate twice a year with a machine that picked up the plugs. Then they top dress it with sand, a little dirt and grass seed. Then they pull a heavy duty piece of outdoor carpet to make sure all the holes are filled.
I'm sure a slicer aerator would work for your task. Just get a load of sand, put some bags of top soil in and a pound of grass seed. Then spread and drag. You'll have a flat lawn after a few yearly treatments.
