First you should know that it mounts at a slight angle out and away from the blade and not at 90 degrees. It mounts with 2 bolts and was not hard to do. After using it one time I found it was made so well that it bent the plow blade. You have to be very gentle with it and not hit the snow banks too hard or push really heavy snow or its going to beat up the plow blade. Maybe it should come with some kind of metal backing washer for the bolts to spread the load out over a larger area and not just bolt heads. Worked ok. Some snow still fell out the side as it isnt that long. The picture looks bigger than it actually is.
