Here are three of my Sears tractors. I also have a restored Custom 8, not pictured. The blue 1971 Suburban 12, I just got last week. The engine was rebuilt a few years ago then had starting problems due to lack of fuel. An inline fuel filter was installed when the engine was rebuilt and the required lines were installed with too sharp bends, restricting fuel flow too much. The yellow & white ST12 was a freebie, given to me, along with a trailer load of attachments recently, including the rear lift. It runs great. Someone has bolted on GM car or truck flywheels for wheel weights. The third one shown is a '63 David Bradley 725 Suburban. It was a gift from a friend. It had been in his family since new. Ownership came down to his sister and him. The sister had passed away and when I asked him about the tractor he gave it to me. I did give him $50 though, although he was reluctant to take the money.
