I eventually got the right pulley only to find it had a small piece cracked out of one of the pulleys. Probably repairable, but I couldn't be bothered. I have since sold the Cox ride on, considering it too much trouble. I am not really into doing up secondhand ride on mowers if truth be told. They are just too heavy for me and my back gives out. I still have the dual pulley here if anyone ever needs one. An engineer should be able to repair the broken out bit.
