Lawn Mower Troubleshooting

One of the first things you’ll notice if you read the comments on some lawn mower reviews, is the fact that some people seem to experience technical problems with their mower that they don’t know how to fix. This leads them to abandon their mower and buy a new one.

However, what is usually wrong with their machine is usually something minor and can be easily fixed. Check a few key components and make a few simple repairs and the mower will usually be as good as new.

Today, I am going to give you an overview of some of the most common problems with a lawnmower and how they can be quickly identified and fixed. This will not only keep you from having to buy a brand new machine every year but will also keep you from having to visit a repair man whenever you have the slightest problem with your machine. Here are the best lawn mower troubleshooting tips that will help you get your mower back out on the lawn.

The Mower Won’t Start

One of the biggest complaints that people have with their mower is that it won’t start. Very rarely is this a situation where the machine has completely died. Most of the time, it is something very simple that can be fixed rather easily.

Check Gasoline: Not only might the tank be empty, but you might also have bad gas. Check your tank and fill it, if necessary, or empty out last year’s gas and add new gas.

Check Spark Plug: Make sure it isn’t disconnected, dirty or loose. Check it, make sure it’s clean and reconnect. Also check the spark plug wire to make sure it isn’t damaged in some way.

Check Filter: Make sure that it isn’t clogged with debris.

Check Carburetor: Try tapping on the side of it with a wrench. Sometimes that is enough to get things moving. If that doesn’t work, then you might need to replace the fuel filter.

Power Loss During Mowing

If your mower suddenly cuts off while you are mowing then don’t worry. This is a common problem and happens to everybody eventually. All you need to do is check out the following components:

Check Cutting Height: If you are attempting to cut grass that is tall and you have your cutting height too low, then this can cause the mower to “choke.” Check the cutting height and raise if necessary.

Air Filter: If your mower isn’t getting enough air, then it won’t run very long at all. And usually the culprit is the air filter. Check it and make sure that it is not dirty or clogged.

Clean Out Clipping: Having a buildup of grass around the blades can result in them not being able to turn and the engine stalling out. This often happens when you are trying to cut wet grass. Simple remove the clippings and 9 times out of 10 the mower will stop stalling.

These are the most common problems with a lawn mower that won’t start or starts but stalls out. Most of the fixes will ensure that your machine is up and running in no time.

Starter Rope Won’t Pull Or Is Hard To Pull

Most of the time this is due to not holding down the safety bar on the mower. The safety bar stops the engine from running whenever the handle is let go. This is to keep the mower from running away and mowing down everything in its path. Make sure that the safety bar (called an engine brake) is held down while you are trying to start your mower.

If that doesn’t solve the problem, then check the underside of the mower’s carriage. If there is a bunch of grass collected around the blades, then the engine of the mower won’t turn. Disconnect your spark plug wire, push your mower to a hard surface and remove the excess clippings from around the blades. This usually solves the problem.

The Mower is Cutting In An Uneven Fashion

Usually this problem is accompanied by some sort of vibration coming from the mower as well. If that is the case, then check for these problems:

Clean Debris From Blades: Once again, it is most likely a problem with debris build-up. If so, then follow the steps from problem no. 1 and clean the debris out.

Check Blades: If you’ve cleaned out all of the debris from under you mower and that doesn’t solve the problem, then you might need to check the blades. They might be dull, broken or loose. Check and replace them as necessary.

Mower Is Smoking

If your mower starts smoking while you are using it, then your first response might be to panic. Before you worry and take the mower to a repair shop, check out these out first:

Check The Oil Chamber: If there is too much oil in the chamber, then it can cause the mower to smoke.

Make Sure Oil Hasn’t Spilled: Sometimes a smoking lawn mower is simple the result of oil spilling out on the exhaust. If this was done while the mower was being filled, then it will eventually burn off. Also check your oil cap and make sure that it is on firmly.

If neither of these items solve the problem or the machine has white smoke coming out of it, then you might need to have the machine checked by a professional.

And that concludes this article on the best lawnmower troubleshooting tips. Hopefully, it will keep you from having to take your mower to a repair shop on a regular basis and keeps your lawn mower running the way it should run.
