Ok, I am a relatively new tractor collector so when I saw this ad for "mower, $50.00" I almost fell over. I called the ad and was told she had quite alot of interest I knew why. I won't tell you what I paid for it, but it was more than $50.00 (Some helpful yuk advised her it was worth more than her asking price) but I got a good deal. Now I am trying to figure out the exact year and model. I know it's a Pennsylvania Panzer SN 90992, but that is all. I think it's a T75 but am not sure. Someone put a replacement Briggs 8HP on it. Any suggestions? Thank you.
