Assuming you mean stiff or hard clay rather than soft, mushy clay, one with thick heavy-duty blades spaced several inches apart, and with a clutch/brake that allows you to vary the advance rate of the drive wheels independent of the rotor speed, because you will need to advance very slowly at times and faster at others, as you don't want to have it jerking you ahead and just walking on top of the clay because you can't stop the wheels without stopping the rotor. This type of machine what is used (generally on a much larger scale) to make soil-cement out of clayey soil for road subbases, dikes, and dams. Unless you are just doing a very small area, you are going to need a full-sized tiller (probably about 200-300cc engine - about 7-10 HP, not a mini-tiller.

I would question, really, why you want to till clay soil - if it is really hard enough or clayey enough that it takes a special type of tiller, then it probably is not going to support growth well, and maybe you should be looking at an overlay of topsoil instead, which is also a lot less work. Or are you talking about tilling in a bunch of organic material and sand to loosen it up ? If that is the case, break the clay up very well first, then AFTER it is loose and broken, overlay with the additives and till them in, otherwise most of your tilling effort will go into remixing the additives and not cutting down into the base clay.
