I have an 81 horse and it uses the same tines that my poulan pro uses. They have 3 mounting holes in them, so I expect they fit many tillers. I measured tine lgth. and hole centers and ordered online. You will have to order right and left tines as needed, I only replaced the badly worn tines. I found them on several sites but don't remember where I got them. They were a name brand and this is my second year for them and they are holding up well.

If it will help you more I will check them tomorrow for a part #.
