To widen the blade I used .090" sheet steel and some 5/16" bar. The lower support for the sheetmetal is at a 135 degree angle so it was easy to make by cutting the bar stock at a 45 degree angle with a circular saw and then flipping the piece and welding it together. I made it 54" because that's standard for other Cub Cadet blades, but after finishing it I thought, why not go even wider like maybe 60"? Oh well, maybe next time.
