I've searched everywhere for info regarding rebuilding the SCV control lever linkage on an open station 4720 and can find nothing helpful. My 2013 4720 (open station) loader 'joystick' has reached the point where it is very difficult to operate with accuracy and consistency. Getting the bucket to operate is now nothing but hit and miss. Has anybody rebuilt the linkage? From what I can determine, there is no relatively simple access to the linkage. It sounds like removing the seat, seat support, seat closeout assembly, fender, etc. is necessary. Does anyone know a reasonable shortcut way to access the mechanical linkage? Thanks for any advice available.
