Do you mean the Alfta track conversion? Do you have any photo?

I'm not sure if it is a Alfta track. It has three tires and a metal track. The tires are- Two are 8 ply and 1 is 12 ply. I do not have a picture as of now it is being restored.Text Black

That sounds like an OC4 Aftatrack, The under carriage was built by a company in Sweden, and was used on several different brands and models. This was advertised alot for logging applications. The main Oc4 crawler was the same except for the undercarriage.
Parts are scarce for the undercarriage, unless there are some available in Sweden, maybe erik knows.
I could fax some info if you want, sorry I can't scan anything at this time.

I saw one sitting in someone's yard over by Wellsboro, Pennsylvania while on a trip in May. I didn't stop and look it over - just saw it while passing by.
