"I was wondering if there are any suggestions for dealing with these 4-6" rocks. Thanks!"
Rent a Harley Rake. You can easily windrow the rocks by taking one of the end wings off and angling the rake. Then put the wing back on the rake & adjust it so it's not angled and works like a box blade. Collect the rocks into pile along the drive. Then pick them up with the bucket.
