I'm working with a John Deere 955 tractor with a 3 point hitch. I'm trying to design a snow plow that extends out the right side to clear a 4' sidewalk without driving the tractor on it. I need to figure out a way to retract it as well so it can be driven down the road. I can always add weight to the left side to counter balance the tractor if necessary for a heavier snow. I'm also thinking about making it so the blade can be removed to be reversed for driving forward or backward.

Has anyone ever done anything like this ? Any help would be appreciated

Thanks
