Is this a common issue with the 2650/3350 tractors?
Ive been manipulating the pedal for some time and I think I finally figured out the problem. It wasn't my neutral safety switch.... It is the pivot point for the neutral arm binding not allowing the bearing on the end of the arm to fully return home into the neural holder. This in turn wouldn't allow the linkage to contact the neutral switch.
Page 3-m23 of the workshop manual will show these parts.
I didn't take anything apart, I just sprayed the pivot on the neutral arm with lithium grease and its been working fine. I should take it apart but I'm concerned the offset bolt on the area in question, and its holding on what looks like some type of split collar, may have some more important stuff behind it.
ETA: there was a member just a few weeks back who found it WAS the neutral safety switch binding due to corrosion.
