Lawn mower repair knowledge is essential for do-it-yourselfers who want to keep their gardens looking as pristine as possible. For those of you who own a lawnmower, here are 11 common problems you’re likely to encounter, as well as the checkup tips you’ll need to fix them.
How to Fix a Lawn Mower and Its 11 Most Common Issues
1. Lawn Mower That Won’t Start
Check the following items if your lawnmower won’t start:
Fuel: Your lawn mower will not operate if the tank is completely depleted. Similarly, if the fuel has been sitting in the tank for more than 30 days, it should be disposed of before cleaning the carburetor.
Gas tank: Check the gas tank for any signs of leakage. Any leaks you discover should be repaired as soon as possible. If not, replacement parts are usually available online through various lawn mower repair websites.
Lawnmowers, like automobiles, rely on batteries to power their engines. Their batteries will eventually succumb to wear and tear and will need to be replaced because they will lose their ability to hold or carry a charge for an extended period of time.
Filters for the air: Clean air filters that are free of dust and dirt can also prevent your lawnmower from starting because they restrict airflow. If the air filter is clogged, simply remove it and flush out all of the debris that has accumulated. If the item is severely damaged, it may be preferable to just replace it entirely instead.
In some cases, loose, dirty, or disconnected spark plugs may be the source of your mower’s inability to run properly. Before you attempt to start your machine, check to see that your spark plugs are properly tightened, clean, and connected. Spark plugs are prone to wear and tear, so it is important to replace them when they become worn or defective.
2. Lawn Mower That Won’t Turn off Unless the Spark Plug Is Disconnected
Just as frustrating as an unresponsive mower is a lawnmower that refuses to shut off. This problem is frequently caused by two people.
The first thing to check is the “kill” or ground wire, which may have been broken or cut. Another thing to look into is whether or not the ignition switch connections are still working.
Start by checking your ground wire. Make sure it is intact and connected to the area it “grounds” to.
Use an ohmmeter to check if your ignition switch’s connection between the “B” and “S” terminals is active if your ground wire is working properly. Your lawnmower should run smoothly after you replace your ignition switch if the problem persists.
3. Lawn Mower That Consumes Too Much Gas
As a result, your mower’s engine is forced to work overtime, increasing its gas consumption in order to perform at its normal capacity. Simply cleaning your air filter thoroughly, or replacing it if it has been more than a year, will solve the problem.
4. Starter Rope That Is Either Stuck or Too Hard to Pull
This problem is often caused by a flywheel brake being engaged. Prior to starting, make sure the flywheel brake is completely disengaged and does not press against your mower’s hand.
Make sure the blades aren’t the problem. The startup process can be hindered if they are in contact with the ground or clogged with grass.
Remove any dirt or grass cuttings from the blades by laying the mower on a flat surface with its spark plug disconnected, then try again.
5. Lawnmower That Overheats
When you notice that your lawnmower is becoming excessively hot while mowing, don’t dismiss it because it is still functional. Instead, take action. It is possible that using it in this condition will make the problem worse unnecessarily.
Check the exhaust of your lawn mower to see if there is any grass buildup before beginning your lawn mower repair. The cooling fins on the head of your lawnmower engine are a structural component of the cylinder head. This is prone to overheating if it becomes clogged, so remove any grass, leaves, and other debris that may have made its way into the cooling fins of your engine.
6. Smoke Rising From the Lawnmower
Despite being one of the most common lawnmower issues, no one knows how to fix a smoking lawnmower. Not to worry, DIYers, your lawnmower is not about to blow up.
Toxic oil chambers are usually the culprit. If your lawnmower’s muffler leaks oil, the engine will smoke as it burns it.
In such cases, stop the engine and let it cool before checking for leaks. Before starting your lawnmower, make sure the cap is tight.
Smoking lawnmowers rarely indicate a major issue. If it already affects your mower’s performance, call a lawn mower repair professional.
7. Lawn Mower With Reduced Speeds
It’s possible that a damaged or dislocated drive belt is the source of your mower’s slow speeds. This drive belt is typically located within the motor casing, though it is best to refer to the manual if you are unsure of how to locate it in your machine.
In order to correct this, turn off your mower before inspecting the drive belt. If it is only slightly loose, it can be reattached; if there is significant damage, it must be replaced entirely.
8. Lawnmower That Fails to Cut Grass
A lawnmower can’t cut grass if the grass is either too long or too wet.
To begin, remember that mowing should only be done in dry weather. To avoid clogging your mower, it’s best to avoid cutting wet grass.
Another possibility is that the grass is too long for your lawnmower’s cutting height setting. Before you begin mowing overgrown grass, raise the deck’s height to its highest setting.
When mowing taller or longer grass, reduce the speed of the mower. It is important to remove any grass, leaves, or other debris that may build up under the mower deck while you are mowing.
9. Lawnmower With Uneven Mowing
Uneven mowing is frequently the result of one of two factors:
Blades that are dull: The blades beneath your mower’s deck must be equally sharp in order for it to function properly. If the blades are too worn, you can either sharpen them with a metallic file or take them to your local lawn mower repair shop. If the blades are too worn, you can also replace them entirely.
Unbalanced accumulation of material: It’s possible that grass, leaves, and other debris have accumulated on one side of your mower. These should be cleaned and emptied as needed.
10. Bumpy or Bouncy Mower
Low oil pressure is one of the most common causes of mowers that feel bouncy or bumpy when they are being operated. To ensure a smoother ride and better performance, keep an eye on your oil levels and replace them as needed.
11. Excessively Vibrating Mower
Lawnmowers can vibrate abnormally and excessively if their drive belts are defective. Make sure it’s installed correctly and is in good working order. You may need to replace worn or damaged drive belts if simple repairs fail to solve your problems.
Loose mounting bolts, an engine running at a lower RPM than recommended, or a cutting deck that isn’t set correctly can all contribute to this issue.
Pro tip: As much as possible, avoid running your lawnmower over hard objects like rocks and roots. These can damage different parts of your lawnmower, which might cause them to need repairs or even replacements.
