I recently purchased my Grandparents house and property. The HT20 I have belonged to my grandfather - and I believe I might have found the original steering wheel center cap while going through some of the shelves in the garage. I believe this is correct - however I have not test fitted it to see. It's huge and looks more like a hub cap for a travel trailer lol. It say's FMC on it instead of Bolens as well.
Does anyone have a set of pictures that show's the various center caps that were used on the HT series tractors? My phone was dead when I found it or I would post a picture. Perhaps I will have a chance to snap a picture of it and some of my other Bolens finds while cleaning the shop/garage and barn out.
