I've always had a problem with the mushroom feet digging in the gravel. So my final fix several years ago was to use a 10 inch solid rubber tire on each side. I basically copied the bracket design for the tire from my Swisher tow behind mower. It uses a 3/4 inch shaft to allow the tires to rotate when angling the plow. My plow is mounted to my loader arms so I can scrap the cement garage apron clean then "curl" the blade back on the tires to plow the gravel driveway. I have it set for a maximum of 1 inch clearance for the gravel. This is done by making the tire bracket shaft extra long and then using shims (washers and/or short pieces of pipe stock) either above or below the DOM tubing that the shaft goes into. This allows me to control the space of the moldboard from the gravel as it wears and should work nicely on a fixed plow setup. My plow is only 6 feet but this same concept would work on a larger plow. I would just upgrade the tire size and shaft.
