In my area (70 miles south of St. Louis) we very rarely get more than 6 inches of snow on the ground at ay one time, but they are calling for 10 to 12 Sat.-Sun., I may be wishing for a blade extension like yours before this is over.
Around 30 years ago I had a Homelite T15 garden tractor, which was a real brute, unlike what they call garden tractors now. It weighed about 1000 pounds, and I had converted it's belly blade to front use, plus I had loaded the tires with iron ballast (a powdered barite mix) We got so much snow one winter that I ended up getting it crosswise in the road and was ramming the snow banks with the blade to push them back so I could plow more snow out of the road.
I wish I had a power system to control the right left tilt for crowning roads when grading. That would be handier for me than the power angle. It would also be a lot harder to design.
edit, here is a picture of the T15 I found on Michaels Tractors. With the front blade mounted, which only extended about 10 inches out the front I could barely close the tailgate on an 8 foot truck bed when I loaded it. That was probably the best all around lawn garden tractor I have ever seen, I would gladly trade my fancy ZTR for a new one like it.
