My front blade has 6 movements, angle left, amgle right, rais, lower, tilt up, and tilt down. It is brand new and I haven't used it yet but I was wondering about the tilt up and down. I was planning on starting out with the skid shoes square to the ground but I was wondering if there were any pluses to running on the toes or heels of the skid shoes. I have it set with the shoes square I have a 1/2" of ground clearance at the blade. ( gravel Drive ) As i tilt down it has less clearance and tilt up for more clearance. I am guessing having the shoes square with the ground is best. Any advice?
