This one hasn't really had an owner and it was part of a surplus auction when Tractor Supply closed out this model from their stores. This is just one of several from that lot. I purchased one of those units from the individual that bought the lot. It does look like it was run in some water or mud, but no evidence that it was in a flood or in very deep conditions. May have sat outside in rain some I don't know. Not really faded or dusty or anything. Nothing seems to settle out of the old oil. The old oil was like dirty pond or creek water very runny pretty much like straight brown creek water. Very overfull and to the point that steam was coming out of the exhaust. It was all the way up near the upper portion of the dipstick. Probably had double or more liquid in it than the ~2.5 qt recommendation. I didn't run it very much like that before I decided to change the oil. Coolant is full looks good proper level and now the oil is too,
