Seeding with a brilion

This will be my first year using a brilion seeder. I've got my ground worked up 3 months ahead of planting time and it's gonna be crusted over on top. My question is do y'all like to have freshly disturbed soil when seeding with the brilion since it's just droping seed on top of the ground or will it plant just fine in my pre worked ground? I'm asking because I need to roundup some rye coming up and this will effect the timing of my spray. Thanks
