I recently acquired a yellow and white model 682. I was expecting a 1710 as I didn’t think they made white 682s. My grandpa, a former IH dealer owner and operator, thought it may be a dealer only model, anyone else hear of this? If so, would it have the regular Kohler 17 horse twin cylinder or an Onan. It had an Onan in it when I got it, and I was hoping to be sure it wasn’t original before I sold it. Thanks.
