I usually find one or two decent sized scrapes (maybe 3-4 feet across) last week of Sept. in to Oct. I put up trail cams and usually get one or 2 mature bucks on it during that time. They do seemed to be used by small bucks as well and also almost exclusivly during the night. I am still not sure if this is just this scrape area (usually under the same tree every year) of if that is when they visit these particular scrapes. I do know that for every scrape i find, no matter whether it is in the middle of the deepest hollow that I only get a handfull of daytime photos on them.
