Welcome to TBN.
That's not a lot of info to go on, but I think the answer would be either. There are a lot of guys who use what they have and make do. Food plot seeds tend to be fairly forgiving so in a lot of cases they don't need a nice fluffed dirt bed like a tiller would give you, and do just fine with the end product of disks.
If you do a search for "food plot" on here, there may be some additional ideas you can read about.
