Proper Tractor / Implement / Mower for 30+ acres

Hey folks. Thinking of a land purchase that has 30+ acres of field. Its all grass and the previous owner had someone that came by and mowed it 3 times a year for the hay (I am told). I think he passed away last year though so I will need to consider doing it myself if I purchase. What is the best equipment I would need to cut this amount of grass. I have a Massey Fergusson 1735 that is pretty capable but I don't have a mower deck for it. I am considering another commercial mower (zero turn or Ventrac possibly) but wanted to know what folks here might recommend. TYIA for any advice or recommendations.
