How To Make a Lawn Mower Go 30 mph

Although lawnmowers are not normally made to travel at high speeds—the fastest riding mower has a top speed of only about 15 mph—certain parts can be altered to make them do so. 

The majority of lawnmower users are unfamiliar with their components. This makes it difficult for people to understand how the mower works. You may boost the speed of your mower to 30 mph by installing a more powerful engine, using bigger pulleys, removing the speed limiter, mounting bigger wheels, changing the way you mow, cleaning the air filter, using the appropriate fuel, and honing the blades.

This article will tell you how to make a lawn mower go 30 mph.

Maintaining the engine correctly, which includes changing the engine oil on a regular basis, is crucial to getting a lawn mower to travel at 30 mph. It is advised to change the oil at least once a year or after 50 hours of use.

Park the lawnmower in a flat area and wait for the engine to cool before changing the oil. The old oil should then be drained into a container after removing the oil drain plug. Replace the drain plug when the oil has been drained, then fill the engine with new oil using a funnel. Check the oil level using the dipstick and add more oil if necessary.

2. Use a Bigger and More Powerful Motor

Utilizing a larger and more potent motor is one approach to getting a lawn mower to travel at 30 mph. A mower with a higher-power motor will be able to travel more smoothly and with better efficiency. 

Researching and choosing the appropriate motor that is compatible with the mower and its present configuration is crucial before upgrading the motor. To guarantee that the new motor is operating effectively after installing a larger and more powerful motor, the mower may also need some extra modifications, such as adjusting the transmission and gearing. To ensure a secure and effective upgrade, it is advised to speak with a qualified mechanic.

3. Use a Premium Quality Engine Oil

Making a lawn mower travel 30 mph depends heavily on using premium motor oil. High-quality engine oil aids in enhancing the mower’s engine performance, enabling it to produce more power and travel at a faster rate. 

It’s important to choose an oil that complies with the manufacturer’s specifications and is made with premium base oils and additives. Place the lawnmower on a level area and let the engine cool before changing the oil. 

Then, use a funnel to add the fresh oil after draining the old oil into a container and replacing the drain stopper. For an engine to run smoothly and last as long as possible, regular oil changes are also necessary.

4. Upgrade the Mower’s Wheel

Using larger and wider wheels can improve the mower’s traction and stability, allowing it to generate more speed without losing control. Look for wheels that are designed for high-speed use and can handle the mower’s weight and power. 

Upgrading the wheels may also require modifying the mower’s suspension and brakes to ensure optimal performance and safety. It’s important to consult with a professional mechanic to ensure that the upgrade is done correctly and safely.

5. Sharpen or Change the Mower Blade

The mower may cut through the grass more effectively with a sharp blade, which will lessen engine strain and enhance performance. If the blade is worn out or broken, it may produce uneven cuts and make the engine work harder, which will slow down the engine’s performance. 

Upgrade to a high-performance blade made for durability and speed. If you want to ensure that sharpening or changing the blade is done safely and correctly, you must adhere to the manufacturer’s instructions. 

6. Check the Mower’s Air Filter

A lawn mower needs to have its air filter checked and replaced in order to reach 30 mph. Airflow restrictions caused by a clogged or filthy air filter can lower an engine’s performance and efficiency. 

Regular air filter inspection and replacement can improve the engine’s ability to breathe, which boosts power and performance. To boost airflow and improve filtration, look for high-performance air filters. Find the filter housing, remove the cover, and swap the old filter with the new one to change the air filter. To ensure that the air filter replacement is done correctly and safely, it is crucial to adhere to the manufacturer’s instructions. 

7. Minimize the Size of the Governor’s Spring

The governor’s spring regulates the engine’s throttle, setting a speed limiter to stop it from operating too quickly and perhaps causing harm. The spring’s size can be decreased to improve the engine’s performance and speed, enabling the mower to travel up to 30 mph. 

However, it’s crucial to use caution and avoid drastically reducing the spring size, since doing so could result in the engine running too quickly and perhaps causing damage or injury. When adjusting the Governor’s spring, it is advised that you either seek advice from a qualified mechanic or adhere to the manufacturer’s instructions. 

8. Check the Spark Plug of the Mower

Engine power and performance can be affected by partial or incorrect combustion caused by a worn-out spark plug. To ensure the best engine performance, regularly check the spark plug and replace it as necessary. 

Look for high-performance spark plugs that are compatible with the engine of your mower and made of high-quality materials. Use a spark plug wrench to remove the old plug and install the new one to replace the spark plug. To ensure that the spark plug replacement is done correctly and safely, it is crucial to adhere to the manufacturer’s instructions. 

9. Check the Mower’s Battery if it is an Electric Mower

In order to get your electric lawn mower to travel 30 mph, it’s crucial to check the battery. The mower can lose power due to a low or weak battery, which will affect its performance and speed. Before operating the mower, regularly check the battery to make sure it is completely charged. 

Consider replacing the battery with a high-performance battery suited for the demands of your mower if it is old or worn out. The mower’s speed and power can be increased by switching to a higher-voltage battery. In order to guarantee that the battery replacement is done correctly and safely, it is imperative that you adhere to the manufacturer’s instructions.


Careful consideration must be given to a number of components in order to increase a lawn mower’s speed to 30 mph, including the motor, the oil quality, the wheels, the blade, the air filter, the spark plug, the Governor’s spring, and the battery. (in the case of electric mowers). 

When making changes to your lawn mower, it’s vital to put safety first and use caution. Any modifications can be done safely and correctly provided you follow the manufacturer’s instructions and get advice from a qualified mechanic. 

Finally, by making the required adjustments and improvements, you may take advantage of a faster and more effective lawn mower that can complete the task quickly and successfully. With the help of the advice in this article, you can now start the process of getting a lawn mower that runs at 30 mph.
