DMF thanks for the pic, great shot... Yes that is the one... LOL dumb me all I had to do was look in my 1525 owners book, it shows the pics of both kinds in there and how to use them.
The 1533, went in yesterday for its 50hrs, I had them check my FEL controls because they wouldn't come back to center. Wouldn't you know it, the control is bad. So who knows when I will see the tractor, I guess next week sometime after they get a replacement controller, my controller is "on" the tractor and not the FEL frame.
