If you own a Craftsman lawn mower, at some point you're going to need parts for maintenance and repair. Craftsman is a brand that has long been associated with quality and reliability, and they're widely known as America's most trusted power tool and outdoor tools brand. But even the best mowers' need a new part or two replaced from time-to-time.

Lawn mower's like Craftsman, can last for decades when they're properly cared for and maintained. This means you'll need to know about the best Craftsman lawn mower parts to use when you need to perform maintenance or repairs. This article will give you an overview of some of the most common Craftsman lawn mower parts.


Craftsman Mower Replacement Blades

Without a quality blade, a good lawn mower will never be able to perform as it was intended. That's why it's important to either sharpen or replace your blades when they're damaged or dull. Many people like to keep a spare set of replacement blades on hand, so if they become damaged, they won't need to go through the hassle of buying a new set before finishing mowing.

Blades can be sharpened to keep them in optimal cutting condition, but over time, they wear down and need to be replaced. When your blades need to be replaced, you'll need to purchase one that is designed to work with your Craftsman lawn mower.

One option is to buy one built by an OEM manufacturer. MaxPower builds a direct fit replacement for Craftsman lawn mowers. If you own a 22" Craftsman lawn mower, you may want to consider the MaxPower 331740B.

Oregon is another excellent OEM manufacturer. In fact, your Craftsman mower may already have an Oregon blade installed since many top manufacturers use them on their new mowers. This makes Oregon Blades a popular replacement choice. The Oregon G3 Gator Blades and G5 Gator Blades are excellent mulching blade replacements.

In addition, Oregon offers many other lawn mower blade replacements. To ensure a proper fit, always check that the blade is compatible with the model number of your mower.

Both MaxPower and Oregon are trusted OEM manufacturers, and choosing to buy either brand ensures you'll have a high quality replacement which meets or exceeds the quality of your original cutting blade.

Craftsman Mower Spark Plug Replacements

If your lawn mower is stalling, not starting correctly, or runs or idles inconsistently, then it may be time to replace your spark plug. A spark plug's job is to ignite the fuel in your lawn mower which provides power to the engine. Over time, spark plugs wear out, but they're easy to replace and very affordable.

Small engines use copper spark plugs, which are resistant to corrosion. They're also designed to perform well in high temperature settings. Craftsman typically uses spark plugs manufactured by Champion, which is a company that's well known for industrial, home tool, and automotive spark plugs.

It's critical that you purchase the correct spark plug replacement. The easiest way to find the plug specification is to look in your mower's user manual. Newer Craftsman mowers list this information in the product specifications section which is usually found on the first page of the manual, under the warranty information.

Using the wrong spark plug, especially if its too long, can damage your mower's engine. If the plug is too short, your mower will have poor fuel efficiency and performance issues.

The Champion 71G is a common spark plug used in Craftsman lawn mowers. But you should always check your manual to make sure it's compatible with your mower model.

Spark plugs are very inexpensive and frequently are available in single, 2 or 3-pack kits. We highly recommend have at least one on hand.

Craftsman Lawn Mower Air Filters

If you have a dirty air filter, you may notice your mower is difficult to start, or it may intermittently cut out when you're mowing your yard. Lawn mowers use easily replaceable cartridge-style filters, and most Craftsman walk-behind mowers have the filter located on the side of the engine assembly, next to the fuel chamber.

You'll want to check your owners manual before attempting to replace the air filter, and to find the correct part specifications.

The majority of lawn mowers made for the North American market use Briggs & Stratton engines, and this includes Craftsman. There's a good chance that the Briggs & Stratton 491588S Flat Air Filter Cartridge will fit your mower, but you should always check before buying.

Craftsman Mower Wheel Replacements

Lawn mower wheels put up with a heavy workload, and they're among the most stressed components on a lawn mower. Wheels are made to last, but it's inevitable that they'll deteriorate and eventually break after extended use.

Your Craftsman Owners Manual will provide you with a complete parts list, which includes the part number and wheel size. 

Most manufacturers use the same mounting system on all of their models when it comes to lawn mower wheels. This makes replacing your mower's wheels relatively easy since the most important thing you need to know is your wheel size.

Of course, if you're concerned about the replaced wheel cosmetically matching the other three, then you may want to order an exact replacement. Many Craftsman walk behind mowers use 11-inch rear wheels, one option is an OEM 11" wheel from Toro.

Grass Clipping Plastic Shroud

If you own a Craftsman riding lawn mower for mulching and want to use the side eject feature, then you'll need to use the right plastic shroud. Otherwise, grass will not be properly dispersed and you'll likely have a huge mess behind the mower.

Plastic shrouds are made from quality ABS material, but they are still subject to damage and wear. If you need to replace yours, then you'll be happy to know that this is one of the most generic Craftsman riding mower parts available. In fact, you should easily be able to find a deflector shield/shroud for a 42" deck mower.

Husqvarna manufacturers a mower shield deflector that is suitable for your Craftsman riding mower, as well as other 42" Husqvarna, Poulan, and Roper riding lawn mowers. If you have a push mower and want to use a deflector shield, you can check out the Husqvarna Clipping Deflector designed for push mowers. Always check your model number to ensure the deflector fits your model.

Other Craftsman Lawn Mower Parts to Keep On-Hand

In addition to the most common replacement parts for servicing and maintaining your Craftsman mower, you should also keep a few other things on hand.

One Craftsman lawn mower part to consider is a lawn mower cover. Keeping your mower clean, dry, and protected from dust and debris helps it runs problem-free for years to come. A simple shroud such as the ToughCover Premium Waterproof Lawn Mower Cover makes sure your mower is protected when its being stored in a shed or in a partially enclosed area. Because it's water proof, and covers the entire mower, you could even use this cover to store your mower outside.

Using the correct lawn mower engine oil protects the internal components from damage, especially considering that lawn mowers are often stored for extended periods of time without being run. A high quality oil is a necessity and you can buy one that has been designed specifically for Briggs & Stratton engines, which are the engines used in Craftsman homeowner mowers.

The Briggs & Stratton 2-Cycle Oil is ready to be mixed with your gasoline, and it even includes a fuel stabilizer.

For mixing and fuel storage, it's a good idea to have a quality fuel can on hand that's made from high quality plastic that won't deteriorate when filled with oil or fuel. A filling nozzle also means that you can fill your lawn mower without making a mess or needing a funnel.
