I have a blade on order for my ct235, and it was quoted to me for somewhere around $175.00.  It was ordered in a stock order and no freight on it.  The parts guy had me call him back with the amount of bolt holes in the bucket.  Evidently there must be a difference in blades somehow.  Mine had 8 bolt holes. It is a reversable blade with a cutting edge on both sides.  Last I checked the blade was still on backorder.  JP
