Experienced gardeners share their insights in answering this question :
If it does nothing when you turn the key then replacing an alternator will not help. Numerous things could be causing this condition. I will try to cover a few. Make sure your PTO for the blades is disengaged and the clutch pedal is depressed. Make sure your battery voltage and all connections are good. Also make sure it is hooked up correctly. There is a fuse, usually near the solenoid, you need to check that. If all the above is good check to see if you have voltage going to the solenoid: There is a small wire that hooks to a spade terminal, you need to have 12 volts on this wire when the key is in the start position. If you do not, then you need to troubleshoot your safety switched. If you have 12 volts, then you may have a bad solenoid. Good luck, hope this gets you in the right direction.

Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
Check/clean/tighten all connections on battery/solenoid/starter/Ignition switch and neg(-) cable to frame or motor. Check to ensure all safety features are working properly and not engaged. Check for an inline fuse, bypass solenoid to see if engine cranks if it does replace solenoid, if no crank replace starter.
You Lose Power in the Middle of Mowing:

Here`s why this happens and what you can do: Dirty Air Filter on Your Lawn Mower: Clean or replace. Dirty Spark Plug: Clean or replace. Build Up of Clippings & Debris: Clean underside of your lawn mower deck as noted above.

A dirty carburetor is one of the most common causes for a lawn mower not being able to start after sitting unused for months or years at a time.
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
If the engine will not crank, you likely have a problem with… Discharged / defective battery or faulty electrical connections. To address these issues, check the battery and charging system for problems. Faulty parts: potentially the safety interlocks, starter motor switch (open circuit) or solenoid.
If your car key won`t turn, it may be because of the transmission being left in Drive or Reverse when the vehicle was shut off. Wear and tear may also cause the key to get stuck. Years of abusing your key may cause it not to function properly.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
Your lawn mower turning over but not starting due to several reasons, such as a faulty or disconnected plug, a disconnected spark plug wire, a clogged air filter, or a contaminated fuel tank. A faulty carburetor, a dirty cutting deck, or a dysfunctional flywheel brake can also cause this.
