I need to check the Safety Switch. Where is that located?
I think it works off of the left foot pedal(start\clutch\brake pedal).
Thank you for your help.

Your engine won't crank. There is a minimum of 3 safety switches that could cause the problem and any one of them not completing the circuit will cause a no crank situation. Clutch, seat and PTO. The PTO engages the blades. They all must have continuity from one to the other and through the start circuit of the ignition switch in order to provide current to the starter solenoid.

You can also jump the switch terminals for an easy and permanent solution to keep them from interfering with ignition operations ever again... :thumbsup:

Where is the safety switch for the Clutch?

Not certain on the 105 but usually if you look under the tractor and watch the mechanical(s) move while operating the clutch / brake you will see something pushing a plastic plunger in and allowing it out when B/C is released. That plastic stationary switch will have wires attached so look for wiring.
