I'll add some more information. I own 65 ares in Northern Michign and about 2/3 is tillable. I want the tractor to work up food plots as well as do my snowplowing. I will also be doing a bit of work for neighbors.
I'm about 5 years from retirement and want to purchase the tractor and have it paid for before I retire. I have a box scraper, post hole auger, 5 ft brushhog, tiller, landscape rake and a couple of other small cat I attachments from when I had my 3600. I have also acquired a 3 bottom plow, 3 point disks, 6 ft brushhog and a couple of other attachments for my mother in law when she sold out. These were all cat II for the tractor they had.
I was first looking mostly at the L5060 but the M5660 has been looking better the more I look. Being in Alaska right now, it is hard to compare them in person and my local dealer in Michigan hasn't returned my calls.
