Uneven Ground

If your mower is cutting lower on one side, it may be due to uneven ground. Uneven ground can cause one side of the mower deck to be compressed, making it cut lower. To fix this issue, you can try adjusting the deck height to even it out or mow diagonally across the uneven ground.

Another solution is to fill in any low spots with soil or level the area. Another cause of uneven cutting can be a damaged or worn blade. Make sure to regularly inspect and replace the mower blade as needed. Finally, check the tire pressure to ensure the mower is sitting evenly on the ground.

By following these tips, you can ensure a more even cut on your lawn.

Bent Blade

If you’ve noticed that your lawn mower is cutting lower on one side, it could be due to a bent blade. A bent blade can cause uneven cuts and make your lawn look patchy. To avoid this problem, it’s important to follow a few key guidelines when mowing your lawn.

How to Fix a Mower that Cuts Uneven

Worn Out Blade

If you notice that your lawnmower is cutting lower on one side, one of the common causes could be a worn-out blade. A blade that has been used for a long time may become dull or uneven due to wear and tear.

Consequently, it may cut grass lower on one side. To keep your grass healthy and properly trimmed, it is important that you replace the blade regularly. Additionally, ensure that the blade is installed correctly so that it cuts evenly. One way to determine if your blade is causing the problem is to inspect it for signs of wear or damage.

If the blade is dull or has nicks or chips, it’s time to replace it. Follow manufacturer instructions carefully when installing the new blade to ensure it is done correctly.

Uneven Tires

If your mower is cutting lower on one side, uneven tires could be the cause. Tires can become flat or worn down on one side, causing the mower to cut at an angle. To fix this issue, check the tires for wear and tear.

Replace them if necessary or inflate the tires to the correct pressure. Make sure that the mower’s deck is level, too. If the mower’s deck is off-balance, it can cause uneven cutting. Adjust the deck to ensure it is level with the ground.

Finally, avoid mowing in uneven or hilly terrain. Uneven ground can cause the mower to tilt to one side, resulting in uneven cutting. By following these guidelines, you should be able to solve the issue of uneven cutting and maintain a well-manicured lawn.

Damaged Deck

If your mower is cutting lower on one side, the problem could be a damaged deck. A damaged deck can cause the blade to tilt, resulting in uneven cuts. To fix this issue, inspect your deck for signs of damage such as cracks, dents, or deformations.

If you find any damage, replace the affected parts or the entire deck if necessary. You can also try adjusting the blade height on the higher side to match the lower side, but this is only a temporary fix. Regular deck maintenance and careful operation can help prevent deck damage and ensure a smooth, even cut every time.

So, be sure to follow these guidelines for optimum mowing performance.


Maintaining a well-kept lawn requires several tools and techniques, among which a mower tops the list. However, uneven cuts and low spots can ruin the look of your lawn and affect the mower’s performance. If you notice that your mower is cutting lower on one side, it may be due to blade damage, worn deck, or uneven tire pressure.

Ignoring these issues can lead to further damage and expensive repairs. The first step is to identify the problem and take appropriate action to rectify it. In some cases, adjusting the deck height, balancing the blades, or replacing the deck might be necessary.

Regular servicing and inspection can help prevent such issues in the first place. Taking care of your mower will not only improve its lifespan and performance but also keep your lawn looking stunning. Remember, your lawn requires gentle care to thrive and deliver the desired results.
