This setup is much more efficient, takes little time to hook up and go, floats on the plow skids, and trips if you hit something. Its 2 bolts and nuts, 4 hose connections and a pin on the lift cylinder. And, it works and drives like its on rails even in 24" drifts. I can run the tractor in high range(3) (9th gear) while doing my entire 1 mile long dirt road, both directions, 20 mph. When the snow is deep and heavy, you need to run a high angle so the snow flys off the blade. Otherwise it will spill over the top. I have full up/down and angle left/right from the loader ports. Plus, the length of the whole rig is just about the length of the tractor. This allows much better maneuverability for turning tight corners and when backing up. I want down pressure to break up occasional ice tracks from where the cars park outside the garage. I use this especially while in reverse.
What helps the winter plow blues is to run the plow over the gravel slowly when its warm outside. This allows you to shave the driveway surface to the plow contour (flat or triangular) instead of rounded crown.
If we would get some decent snow here in Eastern Michigan, I will run a video of how well this rig works. Its just an old truck plow mounted on 2 tractor frame extension pickup points. Same 1 way cylinders. The skids are adjusted to put the blade about 1 inch above the roadway.
