620 Model - 134 CID Red Tiger Engine; the "2" signifies 4-spd trans, NO PTO & NO 3-pt lift; and the 3rd "0" digit defines a 1955-1957 model, the "1" digit defines a 1957-1962 model. Tach/Proofmeter was also never on the 620 models. Plug on dash lamp is new to me.
Here are your pictures you sent me. S/N no doubt listed as a 620 Model, However, you say you have a PTO and 3-point lift. The 620's never had those. They were released as low budget models for use as city, county, state parks pulling mowers. If you have a PTO and lift maybe it was a mutt built by someone.
