Try a-ztractor.com for used wheel horse parts. He has a LOT of old wheel horse's that he has disassembled and then sells the parts (parts are listed under Toro, since Toro was the last owner of the Wheel Horse brand)). There are a lot of parts on ebay also. I think you mentioned finding wheelhorseforum.com there is a lot of good info on that site. I attached an pdf file to my first reply on this thread, it is an owners manual for the 855 & 1055 tractor.
