Currently in the process of restoring my F-12, which is equipped with the power lift unit beneath the seat. I noticed when I bought the tractor the seat sit noticeably off to one side, like it was twisted. In putting it back together I've determine the long leaf type seat spring is bent. I guess the man that occupied the seat for years before me was a tad on the heavy side and over time it just tweaked the spring. It needs to be bent about 1/2" back toward the centerline of the tractor. Wondering if heating and quenching in oil would be sufficient? I don't want to risk breaking the spring later, but it is just gonna be a show tractor, and I weigh only about 180 so it's not gonna be under a lot of stress. incidentally the short inner spring appears to be fine, it's just the long one that appears to be bent. I'd appreciate any input or suggestions...
