Changing your lawn mower blade is a relatively simple task that can be completed in a few minutes. You will need a few tools, including a wrench, a socket wrench, and a new lawn mower blade.
To change your lawn mower blade, first, disconnect the spark plug wire. Then, tip the lawn mower on its side and remove the blade bolt. Remove the old blade and replace it with the new blade. Tighten the blade bolt and reconnect the spark plug wire.
Changing your lawn mower blade is an important part of maintaining your lawn mower and ensuring that it is operating at its best. By following these simple steps, you can keep your lawn mower running smoothly and your lawn looking healthy and green.
1. Brown or yellow grass
Brown or yellow grass can be a sign that your lawn mower blade is dull or damaged. A dull blade will tear the grass instead of cutting it cleanly, which can lead to a number of problems, including:
- Uneven cutting
- Increased thatch buildup
- Scalping
- Damage to the lawn mower
Thatch is a layer of dead grass and other organic matter that builds up on the surface of the soil. A thick layer of thatch can prevent water and nutrients from reaching the roots of the grass, which can lead to brown or yellow grass. Scalping is a condition in which the lawn mower blade cuts the grass too short, which can also damage the grass and lead to brown or yellow spots.
If you notice that your lawn is starting to turn brown or yellow, it’s important to check the lawn mower blade. If the blade is dull or damaged, it should be replaced. Changing the lawn mower blade is a relatively simple task that can be completed in a few minutes. By following the steps outlined in the previous section, you can easily change the blade on your lawn mower and keep your lawn looking its best.
2. Uneven cutting
Uneven cutting is a common problem that can occur when mowing your lawn. It can be caused by a number of factors, including a dull or damaged lawn mower blade. A dull blade will not cut the grass cleanly, which can lead to uneven cutting and a brown or yellow lawn. In addition, a damaged blade can cause the lawn mower to vibrate excessively, which can also lead to uneven cutting.
-
Dull blade
A dull blade is the most common cause of uneven cutting. When the blade is dull, it will not cut the grass cleanly, which can lead to a torn or ragged appearance. In addition, a dull blade can cause the lawn mower to work harder, which can lead to premature wear and tear.
-
Damaged blade
A damaged blade can also cause uneven cutting. A damaged blade may have nicks, cracks, or other damage that can prevent it from cutting the grass evenly. In addition, a damaged blade can cause the lawn mower to vibrate excessively, which can also lead to uneven cutting.
-
Incorrect blade height
The blade height can also affect the evenness of the cut. If the blade is set too high, it will not cut the grass cleanly, which can lead to uneven cutting. Conversely, if the blade is set too low, it can scalp the grass, which can also lead to uneven cutting.
-
Uneven terrain
Uneven terrain can also contribute to uneven cutting. If the lawn has slopes or other uneven areas, it can be difficult to mow the grass evenly. In addition, uneven terrain can cause the lawn mower to bounce or vibrate, which can also lead to uneven cutting.
If you are experiencing uneven cutting, it is important to check the lawn mower blade. If the blade is dull or damaged, it should be replaced. In addition, you should check the blade height and the terrain of your lawn to make sure that they are not contributing to the uneven cutting.
3. Increased thatch buildup
Thatch is a layer of dead grass and other organic matter that builds up on the surface of the soil. A thick layer of thatch can prevent water and nutrients from reaching the roots of the grass, which can lead to a number of problems, including brown or yellow grass, uneven cutting, and scalping.
-
Causes of thatch buildup
Thatch buildup can be caused by a number of factors, including:
- Mowing the lawn too frequently
- Mowing the lawn too short
- Using a dull lawn mower blade
- Over-fertilizing the lawn
- Watering the lawn too frequently or too deeply
-
Effects of thatch buildup
A thick layer of thatch can have a number of negative effects on your lawn, including:
- Preventing water and nutrients from reaching the roots of the grass

-
How to prevent thatch buildup
There are a number of things you can do to prevent thatch buildup, including:
- Mowing the lawn less frequently
- Mowing the lawn to the correct height
- Using a sharp lawn mower blade
- Fertilizing the lawn according to the manufacturer’s instructions
- Watering the lawn deeply and infrequently
-
How to remove thatch
If you have a thick layer of thatch on your lawn, you can remove it using a dethatching rake or a power dethatcher. Dethatching is a process that removes the thatch from the lawn without damaging the grass. It is important to dethatch your lawn in the spring or fall when the grass is actively growing.
By following these tips, you can prevent thatch buildup and keep your lawn healthy and green.
4. Scalping
Scalping is a condition in which the lawn mower blade cuts the grass too short. This can damage the grass and lead to a number of problems, including brown or yellow grass, uneven cutting, and increased thatch buildup.
-
Causes of scalping
Scalping can be caused by a number of factors, including:
- Using a lawn mower blade that is too sharp

By following these tips, you can prevent and repair scalping and keep your lawn healthy and green.
5. Damage to the lawn mower
Neglecting to change your lawn mower blade can lead to damage to the lawn mower itself. A dull blade will put more strain on the mower’s engine, which can lead to premature wear and tear. In addition, a damaged blade can cause the mower to vibrate excessively, which can also damage the mower’s components.
-
Bent or broken crankshaft
A bent or broken crankshaft is one of the most serious types of damage that can occur to a lawn mower. This can be caused by a number of factors, including hitting a rock or other hard object with the blade. If the crankshaft is bent or broken, the mower will not be able to cut the grass properly and will need to be repaired or replaced.
-
Damaged piston or cylinder
A damaged piston or cylinder can also be caused by hitting a hard object with the blade. This can cause the piston or cylinder to crack or break, which will prevent the mower from running properly. In some cases, a damaged piston or cylinder can also cause the mower to seize up.
-
Broken or damaged blade bolt
A broken or damaged blade bolt can also cause serious damage to the lawn mower. This can be caused by overtightening the bolt or by hitting a hard object with the blade. If the blade bolt is broken or damaged, the blade can come loose and cause serious injuries.
-
Damaged deck
The deck of a lawn mower is the part that houses the blade. A damaged deck can be caused by a number of factors, including rust, corrosion, or impact damage. If the deck is damaged, it can cause the blade to come loose or to cut unevenly.
By changing your lawn mower blade regularly, you can help to prevent damage to the mower and keep it running smoothly for years to come.
