Troubleshooting Lawn Mower Systems: Ignition, Electrical, And More

Troubleshooting a lawn mower involves examining various systems: the ignition (battery, switch, spark plug, wire), electrical (voltage regulator, alternator, wiring), fuel (tank, filter, line, pump, carburetor), engine (cylinders, pistons, valves), transmission (shaft, wheels, gearbox), blades (spindles, deck), cooling (oil, filters), and maintenance (blade sharpening, belt/chain replacement, filter cleaning, oil changes, greasing).
