This is the pulley that I need. The smaller is about 3 1/2" and the larger is 7 1/4" ish. It didn't come with the Power Ho, it came with the sickle or reel mower attachment.
Nate, what size shaft does the pulley fit on? 3/4? It looks similat to the pulley thats on an 8r6. Could you modify one of those to work? There is a pulley on ebay right now that looks similar. Item #121087710078
