Where is the picture of what you almost went over on?In my part of MASS up near the NH border we had 12" and then about an inch of hail on top of that. I took out the 580 w/ a 48" blade, started around the back corner of the house and slid into a very precarious location 1 foot from a 30 foot drop. Terra Grips, HDAPs and 200lb of weight didn't help and I thought I was going over. I had given up and was about to tie up to my truck when I thought about the 3600lb winch I had put together for the rear sleeve hitch. Forgot all about it.
I put the winch on and ran it to a lally column in the basement. Stepped on the gas and pulled the trigger. I was out and off the ice in 2 seconds flat. After a quick changes of clothing I was back out and finished up the driveway in about an hour with no other problems at all. My wife thought I was going over for sure and spent the rest of my plow time screaming at me out the window if I got too close to the edge.
