Is your lawn mower struggling to cut grass without losing its RPMs, especially in thicker areas of the lawn?
Maybe it has stopped powering through the gas as it should and it's no longer as performance efficient as it was before, even on high speed settings?
Chances are, your lawn mower has become slower over the years. And it can be frustrating to use it over and over again, especially because it doesn’t give you the working experience that you expect from a power tool.
And that's what we'll cover in this article.

How to Make a Lawn Mower Fast (Steps)
1. Sharpen the Cutting Blades
Sometimes the reason why your lawn mower isn’t working fast enough is that the cutting blades have become blunt over time. If that’s the case, sharpening the blades can increase the cutting speed of the mower and make your next landscaping job easy.
To be clear, the benefit of sharpening the blade extends beyond just making the mower work faster. It also means you can mow an area without necessarily giving it a double pass. In other words, sharper blades, adjusted to a desired height, should give you finer cuts with just one pass.
2. Check the Condition of the Tires
It’s easy to ignore the condition of a mower’s tires and assume that they’re not such a big deal. However, wheels play the role of maneuvering the machine. And if they’re not up to the standard, chances are your mower won’t be nearly as fast when you put it to work.
Whether you own a self-propelled mower or you have a walk behind model, you need to make sure the wheels are in good condition. Clean the wheels from time to time. Make sure you add pressure in the tubes if the tires don’t look well inflated yet.
If the wheels have started to wear out, consider replacing them with a new set. This will go a long way to enhance grip and stability, while ensuring easy movement even on rough terrains. Also, it helps to lubricate the wheels’ bearing from time to time to ensure smooth and consistent motion.
3. Use Clean Gasoline
Your lawn mower is probably slow because the gas tank doesn’t have clean gasoline. If that’s the case, fill it up with a 92-octane (or higher) of fuel. Doing so will ensure the engine runs smoothly and more efficiently, hence a fast lawn mower.
It’s best to avoid fuel of less than 92 octane, as this can have a negative impact on the performance of your lawn mower.
It also helps to check the level of gasoline in the tank before you fire up the mower. Add more gasoline if the fuel level is less than half empty, and then you can start mowing. Doing so will ensure your engine runs faster, allowing you to mow your yard with ease and in the shortest time possible.
Changing the fuel regularly is something you should consider doing. It will make sure the engine works perfectly all the time. And if anything, that’s a good way to maintain the speed of the mower to the most optimal level.
4. Alter the Mower’s Spring
Altering a mower’s spring isn’t something power tool users do more often, but it can help to speed up the speed of the machine in a way. In fact, this technique is quite effective in the case where you want to make your mower feel like a racing vehicle.
There are two ways to alter the spring of your lawn mower. You can opt to shorten it on the governor, or you can do away with it altogether.
5. Replace the Pulley System
This is where you alter the size of the pulley attached to the engine and the one in the back to improve the speed of your lawn mower. If you don’t want to replace the pulley with something of the same size, replace it with a bigger one.
You need to keep two things in mind before you replace the pulley system:
- You should not replace or alter the system unless you’re sure it’s something the mower allows you to do.
- Keep in mind that this technique works only on belt driven lawn mowers
6. Clean the Undercarriage
If you do a lot of mowing on a regular basis, chances are the undercarriage of the machine will have a lot of debris. These may come close to and sometimes in contact with the cutting blades, eventually causing them to block and stop working.
If you notice that your mower is starting to get slow and you suspect that it’s because there’s too much dirt in the undercarriage, then it’s time to do some cleaning.
Cleaning the section on a regular basis will go a long way to make sure your lawn mower works as best and fast as possible.
Here’s the best thing:
Cleaning the undercarriage is very easy and takes a very short time.
Below is how to do it:
- First, remove the spark plug from the undercarriage
- Second, use a high quality brush to remove the debris. Or, you can use a garden hose to spray water to the area.
7 Clean the Air Filter
Cleaning a mower’s air filter on a regular basis may be too much work. But doing so helps to ensure there’s consistent airflow in the system, which in turn enhances the working speed of the mower.
8. Make Sure All the Parts Work Properly
You should check the filters, chain, shafts, belts, and other parts of your lawn mower to make sure they’re working properly. After all, the speed of your lawn mower depends on the functioning of these parts.
Apart from making sure all the parts of the mower work correctly, you should also service the whole machine before and after the mowing season.
