Buying Guide: What to Look For in Lawn Mower Replacement Parts
When my mower starts acting up, I know it’s time to look for replacement parts. But walking into a store or browsing online can be overwhelming if you don’t know what you’re looking for. Over the years, I’ve learned a few key things that make the process much smoother and ensure I get the right part the first time.
The single most important step is knowing your mower’s model number. This isn’t a suggestion; it’s a requirement. I can’t tell you how many times I’ve seen people guessing, only to buy the wrong air filter or blade. Your model number is usually located on the deck of the mower, often near the rear wheels or on a sticker by the engine. Write this number down and have it with you when you shop. This number is the key that unlocks the exact fit for your machine, saving you from the headache of returns and exchanges.
Next, pay close attention to the type of engine your mower has. This is crucial for parts like spark plugs, air filters, and oil. Most residential mowers use either a Briggs & Stratton, Kohler, or Honda engine. Each manufacturer has its own specific part numbers. Just because a spark plug looks similar doesn’t mean it’s the correct heat range or thread size for your engine. Using the wrong type can lead to poor performance or even engine damage.
I also think about the quality of the part. You generally have two choices: OEM (Original Equipment Manufacturer) and aftermarket. OEM parts are made by the same company that built your mower. They are a guaranteed fit and performance match, but they often come with a higher price tag. Aftermarket parts are made by a third-party company. They can be just as good as OEM parts and are frequently more affordable, but you need to buy from a reputable brand. For critical components like blades or carburetors, I sometimes lean towards OEM for peace of mind. For simpler items like a primer bulb or a drive belt, a well-reviewed aftermarket part is often a perfect choice.
Finally, consider the source. I prefer to buy from established hardware stores, dedicated outdoor power equipment dealers, or reputable online marketplaces. Read the reviews from other DIYers. If multiple people mention a part didn’t fit their specific mower model, even though it was listed as compatible, that’s a big red flag. A little bit of research upfront can save you a lot of time and frustration later. Knowing your model number, engine type, and the quality difference between parts will make you confident in selecting the right lawn mower replacement parts for common repairs.
Frequently Asked Questions
How often should I replace my lawn mower’s air filter?
This depends on how often you mow and how dusty your environment is. As a general rule, I check my air filter before the first mow of the season and then every 25 hours of use. If you mow in very dusty or sandy conditions, you might need to check and replace it more frequently. A clogged air filter restricts airflow to the engine, making it run less efficiently and use more fuel. A visual inspection is easy; if the paper filter is caked with dirt and you can’t see light through it, it’s time for a new one.
What is the most common lawn mower part that needs replacement?
In my experience, the spark plug is the most frequently replaced part. It’s a wear item designed to be replaced periodically, typically once a season or every 25-50 hours of operation. A worn-out spark plug is a common reason a mower won’t start or runs roughly. Luckily, it’s also one of the easiest and cheapest parts to replace yourself. Other common replacements include the air filter, mower blade, and oil.
Can I sharpen my mower blade instead of replacing it?
Absolutely, and you should! I sharpen my mower blades a couple of times during the mowing season to ensure a clean cut. A sharp blade slices the grass, while a dull one tears it, leaving the tips brown and vulnerable to disease. However, there comes a point when you should replace the blade. If it has deep nicks, is badly bent, or has been sharpened so many times that the balance is off, it’s time for a new one. An unbalanced blade can cause vibration that damages your mower’s spindle and engine bearings.
Are universal replacement parts a good idea?
Universal parts can be a bit of a gamble. For some items, like certain types of wheels or basic hardware, they work just fine. However, for engine-critical components like carburetors, fuel pumps, or specific belts, I am very cautious. A “universal fit” often requires modification or still doesn’t work quite right. I always try to find the exact part specified for my mower’s model number first. It saves me the potential hassle of trying to make a universal part fit, only to have to buy the correct one later.
What tools do I typically need to replace common mower parts?
You don’t need a fancy garage full of tools for most common repairs. A basic socket set, a set of screwdrivers (both flat-head and Phillips), and an adjustable wrench will cover about 90% of the jobs. For changing the blade, you’ll absolutely need a wrench to fit the blade bolt (often 3/4″ or 15/16″) and a block of wood to wedge the blade so it doesn’t spin. Safety is paramount, so always disconnect the spark plug wire before working on your mower to prevent any accidental starts.
