Zero Turn Lawn Mower Recommendations

Long story short... I currently have a 3/4 acre lot where I live but have a 3 acre lot that my wife and I plan to build on in the next few years. When we bought our house 5 years ago I bought a standard ride on craftsman lawn mower. It has been a decent mower, still runs great but the deck is in bad shape. Over the last month I have been having to jump start it every time I need to mow (I assume the alternator is going bad because I already changed the battery this year) and the belt keeps coming undone. It ate up the second belt in 2 months this past weekend... On top of that it has a slow leak in one of the tires that I am too lazy to change so I just air it up each time. Honestly at this point I am just looking for a reason to get rid of it and buy a new zero turn.

My dilemma is what to buy? I want a mower than will be big enough for my 3 acre lot but not too big for my current home. I also want something that is dependable and is going to last. What do you have and what do you recommend? TIA
