Experienced gardeners share their insights in answering this question :
Sounds like you may have a couple issues.
First you need to remove the spark plug.
You want to check the flywheel key first.

This is easy enough to do. You really just drop the blade and on the end of the shaft is a key.
Get one the same size at your local hardware store for a $2usd maybe.
This is my first thought with the blade not spinning.

The clicking sounds like a classic case of a bad solenoid.

Lift up the engine cowling.
Go to the rear of the engine.
The solenoid should be in view.
Try tapping it with a rubber mallet.
You can try to jump start the solenoid by turning the key on. Make sure someone is sitting in on the mower to be safe.
Take a jumper cable and using only one side of the cable jump the pos to the neg on the solenoid. If the starter engages then replace that solenoid.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

What`s happening? This is a normal function of the seat safety switch. With the blades engaged, weight from the operator allows the seat safety switch to keep the engine running.
Worn or broken blade drive belt – If the riding mower blades are not spinning, the blade drive belt may be worn or broken and unable to engage the blades. If the belt is intact, inspect it to see if it`s loose or slipping on the pulleys then replace it with a new one if necessary.
If your John Deere won`t crank and all you hear are clicking sounds when you turn the key, you likely have a bad battery or a bad connection somewhere between the battery and the starter. Double check that the alternator and battery connections are clean and tight.
Top Reasons why your blades will not engage on your riding mower or tractor: Belt-the number one cause for your blades not to engage is that your belt is either stretched or loose causing it to slip or fall off completely. Belt could have snapped also.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
If the PTO clutch is not getting power, if the clutch solenoid is defective, or if the clutch is worn out, the lawn mower blades will not engage. The PTO clutch is not repairable—if the clutch is defective, you must replace it.
Details. Why does the tractor make a clicking sound and not start? If the riding mower makes a heavy clicking or a rapid clattering sound when the key is turned to the start position, there is a problem with the battery or a part of the starting circuit. The clicking noise comes from a part called the starter solenoid.
If the starter motor spins but does not crank the engine, you likely have a problem with… Faulty or damaged battery. To address this issue, check the battery and charging system for problems.
Whenever the blade is engaged, it rotates on a crankshaft to cut the grass. But if there is interference in this rotation, the engine can overload and shut off or lose power. Check the crankshaft connection to see if it rotates freely. Inspect the connecting hardware for damage or rust.
The most common reason for a surging lawn mower engine is a blockage in the fuel supply, but there are other possibilities: Bad gas. Bad spark plug. Dirty/faulty carburetor.
This is most likely a safety switch issue. Usually the seat safety switch will cause this problem. The mower dies because it thinks nobody is sitting in the seat, and shuts off for safety reasons.

I have a Poulan push mower that after mowing in a ditch started making a loud noise and running rough. It almost sounded as if metal was hitting metal. The mower was vibrating more than normal. I checked under the mower and nothing is hitting. After a few times of stopping the mower engine because it sound as if it is going to die down the mower will not start now. The shaft does not appear bent and the blade appears ok. The mower has oil, a good spark plug and a clean air filter. It was running fine until that moment. I did not see anything that I hit but it is possible I hit something in the ditch like a pine cone or branch. What could the problem be and how would I go about fixing it?
ANSWER : If you are sure the oil level is correct then it sounds like it’s about to die, unfortunately. A pine cone shouldn’t cause any damage, but a large branch may do so. Was it smoking before you shut it down? The vibration could be caused from a bent blade. It could also be caused from a part breaking in the motor. I wish I could have given you better news!

Good Luck,

Lawn mower will start and run for 5 seconds and shut down
ANSWER : Will it stay running with your choke on? if so then clean your carb. if not then look for a blockage from tank to carb. ie fuel shut off, deteriorated fuel line. plugged filter etc

I need to get the blade of the lawn mower sharpened.Any tips on how to disconnect the blade fropm the lawn mower?
ANSWER : There is a jig that you can buy that makes this job SO much eaiser. It is a universal jig that clamps onto the deck and keeps the blade from spinning so you can use a ratchet to remove the nut holding the blade on. One name brand is called a “Blade Hog”. You should be able to find one of these at one of the bog box hardware stores.

Hope this helps,

Self propelled mower will start but want stay running long? it runs about 3 or 4 min. then stop and when i restart it, it will start back up.
ANSWER : The fuel bowl has a float and needle, if the float isn’t floating to open the needle for gas to flow into the carb, it will cut off. A kit can be purchased for about $5 or take yours out and soak and clean then replace. Usually when these go bad its best to replace them.
