TOP 10 Mower Fixes
1. Lawn Mower That Won’t Start
If your lawnmower won’t start, there are a couple of things that you should check out:
Fuel: Your lawn mower will not run on an empty tank. Similarly, if the fuel is older than 30 days, get rid of it before cleaning the carburetor.
Gas tank: Inspect the gas tank for any leaks. Seal any leaks you find if you can, but otherwise, replacements are usually available online in various lawn mower repair websites.
Battery: Just like cars, lawnmowers rely on batteries to run. At some point, their batteries will give in to wear and tear and need replacing as they lose the capacity to hold or carry a charge.
Air filters: Dirty air filters full of dust and dirt can also restrict airflow and prevent your lawnmower from starting. If the air filter is dirty, simply remove it and get rid of all that built-up debris. If it’s too damaged, then it might be better to just replace it altogether.
Spark plugs: Loose, dirty, or disconnected spark plugs may be keeping your mower from running. Make sure your spark plugs are tight, clean, and connected securely before you try starting your machine. Change old and defective ones as spark plugs are prone to wear and tear.
2. Lawn Mower That Won’t Turn off Unless the Spark Plug Is Disconnected
A lawnmower that won’t start is a headache, but one that won’t turn off can be just as problematic. Two culprits are often responsible for this problem. First, the “kill” or ground wire, which may have been disconnected. Second, the ignition switch connections, which may no longer be working due to wear and tear. Start by checking your ground wire. Make sure it is intact and connected to the area it “grounds” to. If your ground wire is fine, move to your ignition switch and use an ohmmeter to check if the connection between the “B” and “S” terminals are active. If it’s not, replace your ignition switch and your lawnmower should work smoothly afterward.
3. Lawn Mower That Consumes Too Much Gas
Lawnmowers are not supposed to consume gas like a thirsty runner who just ran a full marathon without having a bottle of water. If yours does, a clogged air filter is typically your number one suspect. This causes your mower’s engine to work overtime, forcing it to consume more gas to perform at its normal capacity. To fix this, just clean your air filter thoroughly or replace it if it’s over a year old already.
4. Starter Rope That Is Either Stuck or Too Hard to Pull
An engaged flywheel brake is often the reason behind this simple problem. Before you pull the starter rope, make sure the flywheel brake is completely disengaged and doesn’t press against your mower’s handle. If that isn’t causing the problem, check the blades. They might be touching the ground or grass might be clogging them, which blocks the startup process. To fix this, just lay your mower down on a flat surface, disengage your spark plug, rid the blades of any dirt or grass cuttings, then try again.
5. Lawnmower That Overheats
When you feel that your lawnmower typically becomes too hot while mowing, don’t ignore it just because it’s still functional. Continuously using it in this condition may worsen the problem unnecessarily. Start your lawn mower repair by checking the exhaust for any buildup of grass. The cooling fins are part of the head of your lawnmower engine cylinder. This tends to overheat when it gets clogged, so get rid of any grass, leaves, and other debris that may have found their way into your engine’s cooling fins.
6. Smoke Rising From the Lawnmower
While this is one of the most common lawnmower issues people face, surprisingly, no one knows exactly how to fix a smoking lawnmower.
And no, DIYers, it’s not a sign that your lawnmower is about to explode.
Typically, an overfilled or leaking oil chamber causes this. Oil leaking into your lawnmower’s muffler can cause the engine to smoke as it burns the oil. In such cases, simply turn off the engine and wait for it to cool before checking the chamber for leaks. Make sure the cap is sealed tight as well before you restart your lawnmower. Rarely does a smoking lawnmower signal a serious problem. However, if it already affects the performance of your mower, then it is best to consult a lawn mower repair professional.
7. Lawn Mower With Reduced Speeds
A damaged or dislocated drive belt might be the reason behind your mower’s slow speeds. This drive belt is typically found in the motor casing, though it is best to consult the manual if you’re not sure how to access it. To fix this, turn your mower off before inspecting the drive belt. Reattach it if it’s only loose or replace it altogether if there is too much damage.
8. Lawnmower That Fails to Cut Grass
Ironically, grass that’s either too long or too wet causes a lawnmower’s failure to cut grass.
First, keep in mind that you should only do mowing during dry conditions. It’s never a good idea to cut wet grass as this can clog your mower. Second, the grass might be too long for your lawn mower’s setting. Raise the deck’s height above its standard settings before you begin cutting overgrown grass.
Additionally, try to mow at a slower pace when cutting taller and longer grass. Make sure to get rid of grass, leaves, and other debris that may accumulate under the deck as you mow to allow your mower to function at full capacity.
9. Lawnmower With Uneven Mowing
Uneven mowing is often caused by one of two things:
Dull blades: For your mower to function well, the blades underneath have to be equally sharp. You can either sharpen the blades using a metallic file,
bring them to your local lawn mower repair shop, or replace the blades altogether if they are too worn.
Unbalanced buildup: Grass, leaves, and other debris might have built up on one side of your mower. Clean these out and empty them as necessary.
10. Bumpy or Bouncy Mower
Inadequate oil is one of the most common causes of mowers that seem bouncy or bumpy while running. Check your oil levels and make sure to change it every once in a while for a smoother ride and a better performance.
Damaged drive belts can cause lawnmowers to vibrate unusually and excessively. Make sure to have it installed properly and keep it in good shape. Worn-out or damaged drive belts may need replacement if simple repairs can’t answer your problems. Other factors that can cause this problem may include loose mounting bolts, an engine running below the advised RPM, or a cutting deck that isn’t in the right settings.
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.
