In another one of the TEN threads you have posted, you say your soil tends to be dry. Using a spike harrow or your ATV disc harrow to cover the seeds is fine, but leaves the soil open and prone to evaporation followed by crusting, which is not good for germination.
Better to ATV disc harrow, if that is what you have, then seed and cover by dragging timbers, or old fence, or railroad track over the seed, per TED SUMMEY in reply #4, something that will PACK/FIRM somewhat. I used a Brinley 48" plastic drum lawn roller behind my Kubota RTV500 for several years with good results, until frost broke the drum.
Probably packing the seed in/under with ATV wheels would be better than covering/fluffing with the spike harrow.
Best of all is a Cultipacker, which is engineered for this task of covering and preserving moisture around seeds. Note seed in Photo #3.
Consider one of the NO TILL food plot seed mixes. Might be your best bet.
