I also think that the winch is the way to go. I use my rig for landscaping in sandy terrain. It's not like plowing snow -- drop the blade and go. Often, you want to just skim the surface for a finish cut, with the front wheels supporting part or all of the blade's weight. It's relatively easy to do with a winch, but I doubt that you could be consistent when trying to hold the blade in place with one hand and steer with the other.
