Willard resident here. If you ever get back this way you should check out Adam's small engine in Greenwich Ohio. About ten miles east of Willard. They have a pretty impressive lawn and garden junkyard and a lot of parts and equipment inside. They're also located in the former Centaur tractor factory.
You wouldn't be impressed with the F20 seat after a few hours. One of our M had that. It would give you back aches. Definitely after market cause Dad's seat was green. Several Silver Kings in my neighborhood. Fate Root Heath also made a hand crank corn sheller. Used to stop at the Wendy's in Willard. Thanks.
