Rock removal advice
Hello all - I am prepping my backyard for planting of grass seed. I loosened up some soil the other day and came up with a lot of rocks. They range from 1/2 inch to 8 inches to 12 inches in size. I can remove the big rocks no problem, but, the smaller rocks are quite numerous. What sizes should I ignore? Should I remove all, as much as I can?
I walked over to a neighboring plot which is being prepped for a foundation pour. The following two photos show what the soil looks like just after being dug up. I included a quarter for size reference.

I have read in several online "how-tos" that one should remove rocks down to 5 or 6 inches. They never say what SIZE I should be concerned with. As you can see, there's a bunch!
This evening, I built a make-shift soil shifter out of some 1/2 inch screen and 2x4's. It worked really well. However, the prospect of digging up 1500 sq ft of yard makes me a bit queasy. Not to mention disrupting the soil structure and sub surface microsystems and bringing up buried weed seeds, but if I have to I will. Motorized vehicles pulling a rock hounds are not an option because the yard is divided into 3 small areas, about 7 to 10 ft wide.
How much can I get away with? Do I need to sweat the small stuff?
