Ignition Key Switch
Internal copper contacts within the switch housing suffer from carbon tracking and oxidation over time, resulting in an open circuit when the key is turned to the 'start' position. This prevents the 12V trigger signal from reaching the starter solenoid, resulting in zero mechanical response from the machine.

Starter Solenoid
The solenoid acts as a high-current relay; if the internal electromagnetic coil fails or the internal copper disc is heavily pitted/corroded, it cannot bridge the power from the battery to the starter motor. This mechanical failure results in a 'no-start' condition even if the ignition switch is sending the correct signal.

Brake/Clutch Safety Interlock Switch
This tractor utilizes a series-wired safety circuit. If the mechanical plunger within the brake switch is stuck or the internal spring has failed due to debris or fatigue, the circuit remains open, preventing the engine from cranking as a safety precaution against unintended movement.
