Advise on equipment please

I have about 2 1/2 acres that I can use for dirt farming. Currently I use about 1/8th acre intensively planted. What does every one else use to keep about an acre in production. For example does everyone own a tractor, or tiller, no till? I currently use a 6.5 rear tine tiller and some sustainable methods. But the thought of using my tiller for whole acre is daunting, much less two. Is it better to hire ground breaking and just sustain? Please let me know what you do since this land is clear but not farmed in 10 years.
