1. Choose the Right Fuel
- Fresh fuel: Always use fresh, high-octane gasoline specifically designed for small engines. Older gasoline can gum up the carburetor and damage your engine.
- Stabilizer: If you won’t be using your mower for a while, add fuel stabilizer to prevent the gasoline from breaking down.
2. Keep the Fuel Tank Clean
A clean fuel tank prevents debris from clogging the carburetor and affecting fuel flow.
- Clean the fuel tank: Regularly clean your fuel tank to remove any sediment or rust.
Consider the Grass Itself
The type of grass you’re mowing can also affect your lawn mower’s speed.
1. Dense Grass
Thick, dense grass requires more power to cut through.
- Mow frequently: Mow more frequently to prevent the grass from growing too long and thick.
2. Wet Grass
Wet grass is more difficult to cut and can lead to clumping and clogging.
- Mow when dry: Wait for the grass to dry completely before mowing for optimal performance.
Other Tips to Boost Your Lawn Mower’s Speed
- Keep the mower deck clean: Remove any grass clippings or debris from the mower deck to prevent clogging.
- Check the belts: Worn-out or loose belts can reduce the efficiency of the drive system. Replace them if needed.
- Inspect the wheels: Make sure the wheels are properly inflated and rotate freely. Lubricate them as needed.
- Upgrade the engine: For a significant speed boost, consider upgrading to a more powerful engine.
- Consider a robotic mower: If you’re looking for the ultimate in convenience and speed, a robotic mower can be a game-changer.

FAQ
What’s the best way to make my lawnmower faster?
There are several ways to make your lawnmower faster, but the most common and effective is to sharpen the blade. A dull blade will cause the mower to bog down and require more effort to cut through the grass. Sharpening the blade reduces friction and makes the mower run more smoothly, leading to faster cutting speeds. You can either sharpen the blade yourself using a file or take it to a professional for sharpening.
Another way to improve your lawnmower’s speed is by ensuring the engine is running at optimal performance. This involves changing the air filter, spark plug, and oil regularly. A clean air filter allows for better airflow, while a fresh spark plug ensures efficient ignition, and fresh oil reduces friction within the engine. These measures lead to a more powerful engine and a faster cutting speed.
Why is my lawnmower so slow?
A slow lawnmower can be caused by various factors, including a dull blade, a clogged air filter, a faulty spark plug, low engine oil, or a clogged fuel system. When the blade is dull, it needs more power to cut through the grass, making the mower slow. A clogged air filter restricts airflow to the engine, leading to a decrease in power and speed.
Similarly, a faulty spark plug can cause misfires and reduce the engine’s power. Low oil levels can lead to excessive friction, reducing the engine’s efficiency and resulting in slower cutting. Finally, a clogged fuel system can hinder fuel flow to the engine, resulting in a decrease in power and speed.
Can I use a lawnmower engine oil in a car?
No, you should not use lawnmower engine oil in a car. Lawn mower engines typically use SAE 30 oil, which is thicker than the oil used in cars. Using thicker oil in a car engine can cause excessive friction and heat, leading to engine damage.
Car engines require a thinner oil, like 5W-30 or 10W-30, to ensure optimal lubrication at different operating temperatures. It’s crucial to use the right type of oil for your vehicle to maintain its performance and prevent damage.
How often should I sharpen my lawnmower blade?
The frequency of sharpening your lawnmower blade depends on the type of grass you cut, the frequency of use, and the blade’s condition. However, a general rule of thumb is to sharpen the blade at least once per season or before every 10-15 hours of use.
