Get a backblade for snow and grading. Somebody on here had problems with the front spline for the MMM. I bought a 4 foot Woods finish mower with mine way back when, easy on/off and does a nice job of mowing.
My only regret is that I didn't buy a FEL with my tractor. I bought it new in 1978. I saw a post on here about aftermarket FEL. Don't remeber the name or cost, I had it saved, but I lost my harddrive. Do a search and you'll find it.
In 2006 I bought a 50" Buhler snowblower that works great. Problem is I had to put 300 lbs of weight on the front bumper to keep the front wheels on the ground. The blower weighs about 400 lbs or so.
Happy tractoring.
