The 1220 my wife has adopted has the stock seat pan on it. The trouble is that she doesn't have a lot of flexibility and has trouble getting on and off the tractor. She needs to swing her leg over the seat, but even the seat back on the Bolens pan is too high.
What we need is a very low-profile seat that will fit. I thought about an old pan seat like the Ford 8N used to have, but all of those I've seen are made to be mounted on a post — the relatively flat fender of the 1220 doesn't seem like it would be compatible.
Doesn't necessarily need to be padded (though she'd like it more if it were.)
