Alright, here is the deal. 8.5 Western Unimount MVP with center rubber flap. I started with a brand new set of edges last year with new rubber center flap. Wore edges down around an inch last year so I have plenty of edge left but the center rubber flap is worn down to the bolt holes and trashed already. A frame is level and don't understand what is going on. I went to my local dealer and asked and he said to raise up my frame on the truck one set of bolt holes. Plowed once this way and the a frame is slightly higher on the truck end. Now the edges out toward the end of the plow is a 1/4" more worn then the center after an hour of plowing. I am at my wits end. I shouldn't have to replace my edges every year. Does anybody have an insight on this?
