Organ Grinder,
I also saw your post under the Mahindra forum.
This is just one more opinion, but I think you are looking at the wrong equipment. I have a Mahindra 2015. It is one tough tractor, and you won't find a better tractor in that class. It sure seems like overkill for what you want to do. I bush hog several acres with my 2015, but I mow about an acre of lawn with a Cub Cadet lawn tractor. Also, a 4WD tractor is an expensive option for what you want to do. But, with that said . . .
If you are really particular about your lawn, I'd sure look at a Zero Turn mower. They will do a much better job than any mid-mount or finish mower.
For snow removal, a tractor is OK. I do over a half mile of driveway, part of it is very steep. I need chains, I use a 6-foot rear blade, and the front end loader. I also have a 28-inch wide walk-behind "big mouth" snow thrower just in case of a really big storm that the tractor can't handle.
If I had what you have, I'd look at a good garden tractor with a snow blower. For 15 years I used an 18 hp Craftsman with weighted agricultural tires and chains. It never met a snow storm it couldn't handle.
Good luck,
Knute
