Starter Solenoid
The clicking sound confirms the solenoid coil is receiving power and moving the plunger, but the internal copper contact plate has likely developed carbon buildup or pitting. This prevents the high-amperage current from the battery from bridging to the starter motor lead. Replacing the solenoid restores the low-resistance path required for the starter to overcome engine compression.

Negative Battery Cable
Electrical resistance in the ground circuit often prevents the starter from drawing sufficient current despite the solenoid engaging. Over time, vibration and moisture cause oxidation at the point where the cable meets the mower frame, creating a bottleneck for the return current flow. A new cable or cleaning the contact point ensures a complete, low-impedance circuit for high-load cranking.

Starter Motor Assembly
If the solenoid and cables are functional, the starter motor's internal brushes may be worn or stuck, preventing the armature from spinning when energized. The clicking signifies the bendix gear may be attempting to engage the flywheel, but the motor lacks the torque to rotate due to internal electrical shorts or mechanical binding.
