Problem was under the seat. Multiple posts before because no one had the answer & no one new was posting their guesses. So here is the answer: There are a pair of yellow rubber cone shaped cushions inside a pair of springs. They had rotted down to fragments. Talked to a JD guy & he knew the answer right away. $40 later & some fussing with it & it spun right up.
