I want to make a brush guard for the top of the blade of a D3G with a 10 foot blade. I want it to help control the tree that gets over the top of the blade and wedges between the trunion tower complex and the radiator guard. I was thinking of using quarter inch mild steel (angle, channel and round). I was going to make it about 6 foot wide to center on the blade and about 1 foot high. Any suggestions would be appreciated. How high does it have to be? Should it go straight up or slant out in front of the blade?
