Are you tired of your lawn mower dragging its belly across the lawn, leaving unsightly tire marks? Perhaps you’re dealing with uneven terrain that requires a higher ground clearance for a smoother, more efficient cut. Whatever your reason, learning how to raise the wheels on your lawn mower is a valuable skill for any homeowner. In this comprehensive guide, we’ll explore the why, the how, and the essential considerations for adjusting your mower’s ride height.
In short, raising the wheels on your lawn mower involves adjusting the height of the mower deck using a series of levers, screws, or other mechanisms. This can be achieved on most mowers through a combination of mechanical adjustments and, in some cases, by swapping out different sized wheels. We’ll delve into the details of each method, providing clear instructions and helpful tips to ensure a successful and safe process.
Why Raise Your Lawn Mower Wheels?
There are a number of reasons why you might want to raise the wheels on your lawn mower. Here are a few of the most common:
1. Uneven Terrain: If you have a bumpy or hilly lawn, raising the wheels can help prevent your mower from scalping the grass in low spots and provide a smoother cutting experience.
2. Thick Grass: If you have a lawn with long, thick grass, raising the wheels can help to reduce the strain on your mower’s engine and prevent the blades from clogging.
3. Mulching: For those who mulch their grass clippings, raising the wheels can help to ensure that the clippings are finely chopped and distributed evenly across the lawn.
4. Mower Deck Protection: Raising the mower deck can help to prevent it from being damaged by obstacles in your yard. This is particularly important for areas with rocks, roots, or other debris.
Understanding Your Lawn Mower’s Deck Adjustment System
Before you begin adjusting your mower’s wheels, it’s important to understand the specific deck adjustment system on your model. Most lawn mowers utilize one of the following methods:
Lever-Based Adjustment
1. Lever Location: Look for a set of levers, usually located on the underside of the mower deck, near the wheels.
2. Lever Function: These levers control the height of the deck. Each lever corresponds to a specific wheel.
3. Adjustment Steps: Simply lift the levers to raise the deck and lower them to lower the deck. There are usually markings on the levers or the deck itself indicating the different height settings.
Screw-Based Adjustment
1. Screw Location: You’ll find adjustable screws, typically located on the underside of the mower deck, near the wheels.
2. Screw Function: These screws are used to adjust the height of the deck by turning them clockwise to raise it and counter-clockwise to lower it.
3. Adjustment Steps: Use a wrench or screwdriver to rotate the screws until the desired height is achieved. You’ll likely need to refer to your owner’s manual to find the correct settings.
Wheel Swap Adjustment
1. Wheel Replacement: Some lawn mowers offer the option to swap out wheels of different heights.
2. Height Adjustment: This approach allows you to change the ride height by simply replacing the standard wheels with taller ones.
3. Availability: You might need to purchase replacement wheels separately or through your mower’s manufacturer.
Step-by-Step Guide to Raising Your Lawn Mower Wheels
Safety First: Before you start working on your lawn mower, always disconnect the spark plug wire to prevent accidental starting.
1. Identify Your Adjustment System: As discussed above, determine whether your mower has levers, screws, or a wheel swap system.
2. Refer to the Owner’s Manual: Your owner’s manual will provide specific instructions and height recommendations for your model.
3. Prepare Your Work Area: Find a level surface and ensure the mower is stable.
4. Adjusting with Levers: If your mower has levers, lift each one to the desired height setting. Make sure the levers are securely locked in place.
5. Adjusting with Screws: If your mower has screws, use a wrench or screwdriver to turn each screw clockwise to raise the deck. Refer to the owner’s manual for the correct number of turns for each height setting.
6. Adjusting with Wheel Swap: If your mower allows for wheel swapping, replace the standard wheels with taller ones. Make sure the new wheels are securely fastened.
7. Test the Height: After making any adjustments, test the height of the deck by measuring the distance between the ground and the underside of the deck. Ensure that all wheels are at the same height.
8. Reconnect the Spark Plug Wire: Once the adjustments are complete, reconnect the spark plug wire.
9. Test Drive: Run your mower on a flat surface to confirm that the adjustments are satisfactory.
Important Considerations for Adjusting Your Lawn Mower’s Ride Height
1. Mower Type: The type of lawn mower you have will determine the available adjustments and the recommended height settings.
2. Grass Type: The type of grass you have will also influence the ideal cutting height. For example, tall fescue thrives at a higher cut than Bermuda grass.
3. Frequency of Cutting: If you mow frequently, you can maintain a slightly lower cut. But, if you mow less often, a higher cut may be more suitable.
4. Engine Load: Raising the wheels too high can increase the load on your mower’s engine, making it harder to cut and potentially causing damage.
5. Mower Deck Stability: Ensure that the deck is securely supported after making any adjustments.
6. Regular Maintenance: Keep an eye on the adjustment mechanisms and replace any worn or damaged parts.

Raising the wheels on your lawn mower can offer numerous benefits, from smoother cutting on uneven terrain to reduced stress on your mower’s engine. By following the steps outlined in this guide and considering the factors discussed above, you can ensure that your mower is properly adjusted for optimal performance and a beautifully manicured lawn.
Frequently Asked Questions
Why would I need to raise the wheels on my lawn mower?
Raising the wheels on your lawn mower can be beneficial in several situations. If you have a lawn with uneven terrain, such as hills or bumps, raising the wheels can help the mower navigate more easily and prevent the blades from scalping the grass. Additionally, if you have a thick lawn, raising the wheels can create a larger gap between the deck and the ground, allowing for better airflow and reducing the risk of clogging. Lastly, if your lawn mower has a tendency to bog down in wet conditions, raising the wheels can help to improve traction and reduce the chances of the mower getting stuck.
What tools will I need to raise the wheels?
The tools you’ll need for raising your lawn mower wheels depend on the specific model and design. However, you’ll generally need a wrench or socket set that matches the size of the wheel nuts. You may also need a jack or a lifting device to raise the mower off the ground. It’s also a good idea to have a flat surface and some blocks of wood for stability. If you have a riding mower, you may also need a torque wrench to ensure proper tightening of the wheel nuts.
How high should I raise the wheels?
The height you raise the wheels on your lawn mower depends on the specific needs of your lawn and the type of mower you have. Generally, a slight increase of 1/2 to 1 inch is sufficient for most lawns. However, if you have a particularly uneven lawn or a thick lawn, you may need to raise the wheels higher. It’s always a good idea to start with a small increase and adjust the height as needed. Avoid raising the wheels too high, as it can affect the mower’s stability and make it difficult to maneuver.
What are the risks of raising the wheels too high?
Raising the wheels on your lawn mower too high can lead to several issues. Firstly, it can affect the mower’s stability and make it more prone to tipping over, especially when navigating hills or uneven terrain. Secondly, raising the wheels can make it more difficult to maneuver the mower, as the increased ground clearance can reduce traction. Thirdly, a higher cutting height can lead to uneven lawn trimming and create scalping issues. Lastly, raising the wheels too high can put additional stress on the mower’s components, potentially leading to premature wear and tear.
How often should I check the wheel height?
