Hey Bubbie,
First off a rock rake is not all that expensive and they work like a top.
Second, rocks will ALWAYS resurface, if you want to avoid having to constantly sharpen and replace bent blades on your mower then remove the rocks.
Even if you get the ground broke up nice and get all the rocks you can find removed within a few years more WILL come to the top, (or at least arund here they do).
What I do when I am working ground for a yard is first till, or disk the ground to break it up, then use the rock rake to gather the rocks into a smaller area so I can load and haul off, now the rake will also move some dirt around, so I have an angle frame welded together in a triangle 5 feet wide, and just deep enough to hold concrete blocks, then I drilled a series of 3/8 inch holes about every 4 inches along the width, and used grade 8 bolts 3 inches long bolted into each hole, then get a piece of chain link fence 5 ft square and use heavy wire to attach it to the back of the frame so it will drag along behind the frame with the concrete blocks on it, this will help to break up any more clods of dirt, and the fencing will do a great job of leveling the dirt, it will also help gather any more rocks.
Running this rig around the area severa time will give you a very nice smooth area, to plant grass seed on.
I would not use a roller to compact the ground, just cover your seed with a light coating of straw to keep it from washing away until it has time to sink in after a few rain showers.
The ground will naturally compact after some rain and you mowing it.
Best Regards
Paul
