I seem to be having an issue with the safety switch for the pedal. I took it in once and cost me 120 bucks for them to "remove debris" from what I think is a plunger safety switch for the pedal. Its starting to act up again but I'm having a hard time locating the debris or the switch. Currently I can shake the tractor while turning key to start it but I would like to fix this. Anyone have any guidance or pics of location and how to access this switch? Thanks in advance
