How to Make a Lawn Mower Go Faster
Lawnmowers, while relatively simple machines have a variety of features that can make them more efficient. For example, one way to increase the speed you cut grass is by raising the blades on the lawn mower’s deck higher off the ground. You can also adjust your engine governor or install an aftermarket governor kit for your specific model to change how fast it will run.
For most homeowners simply looking for ways to save time and energy in their yard work routine, adjusting these two variables should be enough to keep up with their lawn care responsibilities without getting too worn out! So in this blog post, we will talk about how to make a lawnmower go faster and some tips for maintaining it in the long run.
7 Reasons Why Your Lawnmower Get Slower Overtime:
1. The Blades Get Dull
If your mower’s blade is dull, the engine will have to work harder to cut the grass, making it go more slowly. A sharp blade will cut the grass more cleanly, with less drag on the motor, so you can work faster and more efficiently. A sharp blade also cuts the grass better, so your lawn will be healthier.
When changing a mower blade, make sure the engine is turned off and disconnect the spark plug wire from the spark plug. This will prevent you from accidentally starting the engine while you’re working on it.
Use a wrench to remove the old blade from the mower deck. Be careful not to damage the deck when you remove the blade.
Install the new blade by aligning the holes in the blade with the holes in the deck.
2. The Grass Gets Thicker
As the grass collects around your lawnmower blades, it gets thicker and harder to move through. Eventually, this can create too much load for the engine, which stalls or slows down to maintain its power and speed while working on a thicker area of grass.
3. The Fuel Gets Old
If your mower’s fuel is stale or old, it can cause a few problems with the engine. Starting up may be more difficult, and the mower may stall during operation. Over time, the fuel may worsen and create a rough idle that will slow you down until you get a replacement. You can also check your mower’s spark plug to see if it is dirty or old. Replacing an old spark plug can help with the performance of your mower.
4. The Air Filter Gets Caked Up
Stale or old fuel can cause problems with your mower’s engine. The power won’t fire as quickly and smoothly when you try to start up, leading to a stall during operation. Over time, it may also worsen and create a rough idle that will slow you down a little bit until you get a replacement.
5. The Air Gets Stale
The air is just as important to your engine’s performance as the fuel that powers it. A build-up of debris around the outside of the mower can reduce airflow and decrease gas efficiency, causing a slow-down or stall during operation.
6. The Spark Plugs Get Dirty
If the engine isn’t firing as quickly as it should, your machine’s speed can be significantly reduced. This often happens when the spark plugs are dirty and gunked up, which causes a slower start-up and overall slow-down during use.
Sometimes this is caused by cheap gas that contains extra ‘moisture’ inside of it to help keep it from going bad too quickly. This water collects over time and clogs the engine up a bit, just like a dirty spark plug does.
7. Rust and Grime Build-up inside the Carburetor
Over time debris and rust can collect inside your carburetor or the part that mixes air with fuel to create the spark you need for your lawnmower. When this happens, it can cause a slow-down in engine speed which will show up as lower RPMs than usual when you engage the blades. This build-up needs to be cleaned out thoroughly.
8 Methods on How to Make a Lawn Mower Go Faster:
1. Sharpen Your Blades
The sharpest blade you can get is best so that the motor only has to work as hard as it needs to, not more or less than necessary. Check your blades regularly for nicks or dents so that they stay in tip-top shape.
2. Check the Air Filter
If that air filter has been collecting dust and debris, it may need a good cleaning or replacing altogether. A dirty air filter could contribute to poor fuel mileage and poor engine performance; this should be your first step in making your lawn mower go faster.
3. Replace Spark Plugs
It may be time to replace your spark plugs if you find that your lawnmower won’t start as well as it used to or starts hard and then dies. A sign of old spark plugs is decreased engine power and poor fuel mileage.
4. Up Your Engine Oil Ratio
Refer to the manual to see how much engine oil is recommended. If your lawnmower doesn’t have a lot of hours on it, try increasing the amount slightly. This will help keep moving parts lubricated and prevent them from becoming worn out too quickly.
5. Add Fuel Injector Cleaner
Adding a little fuel injector cleaner to your lawnmower will help speed it up by burning up old gasoline buildup. Check the manual for the recommended amount to add, and be careful not to overdo it with the injector cleaner if you are unsure. If you don’t have any lawnmower-specific injector cleaner, you can also add a little rubbing alcohol to the tank.
6. Add a Belt Conditioner
Belt conditioners are a great way to keep your engine running smoothly and your lawnmower cutting grass effectively, especially during wet conditions. This will help protect against corrosion that could shorten the life of your belts. For the most part, you can apply belt conditioner with a spray bottle, which makes it easy to get a nice even coat. Then, simply wipe off any excess with a clean cloth or paper towel and you’re good to go!
7. Add Reducers for Reduced Rotation
Reducers will help reduce the RPMs of your lawnmower so that it can power through tough grass or inclines more easily. Many blades designed to cut at a slower speed can achieve better results when used with a reducer.
8. Change Your Fuel Type
Changing to higher octane fuel can also help engine power and performance, especially if it’s time for an oil change anyway. Higher octane fuel is worth a shot but may not provide substantial results.
Things to Consider When Making a Lawn Mower Go Faster:
1. It is important to remember that you do not want to make your lawn mower go too fast. If the machine goes too fast, it will no longer cut the grass and will become useless.
2. Your lawn mower needs to be in good working order to go faster safely. Therefore, you should check that all the wheels are firmly attached, there is oil in the lubricant reservoir, and the blades are attached securely before you attempt any speed modifications.
3. The weight of your lawn mower may make it too heavy for top speeds, so if you are lightening it, be sure to increase the speed proportionally.
4. Lawnmowers have a maximum safe rotation of about 20,000 RPMs. Anything faster can damage the bearings and motor of your lawnmower.
5. The more significant the engine, the more power it can produce and the faster your lawnmower will go.
6. You may need to repair your lawnmower to make it go faster, and there is a problem with any part of the machine that prevents maximum speed.
How Fast Can a Lawn Mower Go?
A lawn mower’s top speed is determined by its motor. Most lawn mowers have a top speed of 4,000 RPM, which means the blades spin at more than 100 miles per hour. If you want to make your lawn mower go faster, you can upgrade the motor.
the easiest thing is probably just replacing its stock motor with one of higher power ratings. Such engines, which have the same horsepower as stock motors but a higher maximum speed, can be purchased at an auto parts store.
The best way to get your lawnmower to go faster is by using a different blade. This will create more airflow on the underside of the engine, which in turn produces more power for you. Changing out blades can be done with some simple tools and basic knowledge about what kind of blade works best for your lawn’s landscape or type of grass.
