Can't go wrong with a Mahindra Max 28xl. I have about the same size property and found it works very well. I have the FEL, MMM, BH and tiller, rock rake and box blade. I'm amazed how munch I use my tractor.
Are you in Iowa? Just curious where you would get a mahindra and what the cost is also? Is mahindra grey market or up to us specs?
