Buying Guide: How to Choose the Right Lawn Mower Parts
When my mower starts sputtering or just won’t start, I know it’s time to figure out which part needs replacing. Over the years, I’ve learned that grabbing the first part I see is a recipe for wasted time and money. Here’s my personal guide to picking the right lawn mower parts for replacement and repair.
First, you absolutely need to know your mower’s model number. This isn’t a suggestion; it’s the most important step. I always look for a sticker or metal tag on the mower’s body, often under the seat or on the frame. This number is the key to finding parts that will actually fit. Searching by model number is far more reliable than just using the mower’s brand and general size.
Next, I think about the type of part I need. Is it a wear-and-tear item or a more complex component? For things like air filters, spark plugs, and blades, I often go with reputable aftermarket brands. They can offer great performance at a lower cost than the original equipment manufacturer (OEM) part. However, for critical engine components or complex electronics like a carburetor or ignition coil, I tend to lean towards OEM parts. They are guaranteed to fit and work exactly like the original, which saves me from potential headaches down the line.
Material quality is another big one for me. When buying a replacement blade, I always check if it’s made from hardened steel. A cheap, soft blade will dull quickly and might even bend or break, which is a safety hazard. For belts, I look for ones with strong cording and flexibility. A brittle belt will snap under stress. It’s worth paying a few extra dollars for a part that will last multiple seasons.
Finally, I always check the return policy before I click “buy.” Even with the correct model number, sometimes a part arrives and it just doesn’t fit right. Buying from a retailer with a hassle-free return policy gives me peace of mind. I also read through a handful of customer reviews to see if others have had success with that specific part on a mower similar to mine. This real-world feedback has saved me from making a bad purchase more than once. Following these simple steps has made my own repair projects much smoother and more successful.
Frequently Asked Questions
What are the most common lawn mower parts that need replacing?
From my experience, a few parts wear out much faster than others. The air filter gets clogged with grass and dust, the spark plug fouls over time, and the mower blade dulls or gets damaged from hitting rocks. These are the parts I replace most often. Belts on riding mowers also stretch and crack, and the battery will eventually lose its ability to hold a charge. Keeping a spare spark plug and air filter on hand is a simple way to avoid being stuck with a non-starting mower.
How often should I change the oil in my lawn mower?
This is a maintenance task I never skip. For most walk-behind mowers, I change the oil once a season or after every 25 to 50 hours of use. If you use your mower heavily, you might need to do it more frequently. For riding mowers, I always check the owner’s manual for the specific interval, but it’s often around 50-100 hours. Fresh oil is the lifeblood of the engine, and changing it regularly is the single best thing you can do to extend your mower’s life.
Can I use any spark plug in my mower?
No, you really shouldn’t. Spark plugs come in different sizes, heat ranges, and thread lengths. Using the wrong one can cause poor performance, difficulty starting, or even engine damage. I always look up the specific spark plug type recommended by my mower’s manufacturer. The model number of your mower will lead you to the correct part number for the spark plug, ensuring a proper fit and function.
Is it safe to sharpen my own mower blade?
Yes, it is safe if you take proper precautions. The most important step is to disconnect the spark plug wire to prevent any chance of the engine accidentally starting. I secure the blade in a vise and use a metal file or bench grinder to sharpen it, being careful to maintain the original cutting angle. The key is to remove an equal amount of metal from each end to keep the blade balanced. An unbalanced blade will cause excessive vibration that can damage your mower’s engine bearings.
Where is the best place to buy lawn mower parts for replacement and repair?
I shop in a few different places depending on what I need. For common items like spark plugs and air filters, my local hardware store or big-box home improvement center usually has what I need. For more specific parts, I find that online retailers have the widest selection. I can enter my mower’s model number and see dozens of options, from OEM to aftermarket. For very old or rare mowers, specialized websites and even local small-engine repair shops are my go-to sources.
What does it mean if my mower is blowing white smoke?
When I see white smoke, it typically points to one of two issues. The most common cause is that oil is getting into the combustion chamber. This could be because the mower was tipped on its side, overfilled with oil, or has a worn piston ring or valve guide seal. If the smoke has a sweet smell, it could be coolant burning, but this is rare in most air-cooled mower engines. If the smoke continues after an oil change, it’s a good idea to have a professional take a look.
