A cultipacker is used to compress the soil. That being said, look to borrow one of those lawn rollers from a neighbor if you can. I have a cultipacker, but if I didnt, I bet one of those would work better then a drag. A lot of the smaller seeds dont like to be burried more then 1/4". For those its best to cultipack, then spread your seed, then culitpack again. Your drag probably works pretty good, just might be burring some seed deeper then others. Make sure to level the plot with a drag prior to spreading the seed as well, or you will have seed that gets burried to deep. Plant it up, and post some pics in about 25days or so.
