1980 This is an Arms co. Tri-rod. I haven't been able to find anything about it on the internet aside from a few pictures on Google. It has a Briggs an Stratton 8hp engine. I had it running last year. And I pulled it out this year and It wont start. I think it only needs the carbs cleaned but I just don't have the time for it anymore. I have never seen another one in person. It is a blast.
