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 :

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.
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.
If your vehicle won`t start, it`s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you`re dealing with a battery or an alternator problem.
Touch the metal shaft of a screwdriver to both of the large terminals at the same time. If the engine turns over and starts, the solenoid is bad and should be replaced. If the starter motor does not run, the motor itself is probably defective.
Tractor may be starving for fuel.

Sometimes the fuel cap prevents the fuel tank from breathing. The fuel tank can develop a vacuum. This could cause fuel to stop running to the engine – causing it to stall. If this is the case, give it an hour or two, and the tank pressure will reset and equalize.

There are 4 safety interlock switches on our lawn and garden tractors. The locations vary slightly between Step-Thru® and box frame tractors.
Safety switches operate both automatically, protecting against circuit faults, and manually in the case of a needed emergency stop or for planned maintenance and repairs.
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.
The most common reason cars don`t start is a dead or faulty battery. Even though most cars run on gasoline, they all require electrical power to function. The starter that cranks your engine to start requires an electrical signal to fire. If something`s wrong with your battery, your car engine won`t turn over.
