How to Make My Riding Lawn Mower Go Faster

One of the most common questions we hear asked is how to make my riding lawn mower go faster. Lawn Mowing season is here, and you want to get through your yard as quickly as possible. So how do you make your riding lawn mower go faster? Luckily, it’s an easy fix! Follow these blog posts till the end to know-how.

You can adjust the tire pressure to increase the speed of your ride. Low tire pressure will cause more drag on the ground, which slows down your lawnmower, so inflate those tires before starting up again!

Adjusting blade height might help too. A taller blade would give off less air resistance because there’s less lift for the blades to produce when they’re higher than normal grass level, meaning that we can now more quickly! So let’s get started.

How to Make My Riding Lawn Mower Go Faster

7 Reasons Why Your Lawn Mower Slow Down:

1. Dirty Air Filter:

A dirty air filter restricts airflow and results in engine power and performance loss. Check your air filter regularly for debris and replace it as needed.

2. Dirty Spark Plug:

The spark plug starts the combustion process, allowing the engine to run. If your spark plug is dirty or fouled, then you’ll experience a very noticeable drop in power and performance. Remove, clean, and gap or replace your spark plug so that it fires correctly and at the right time.

3. Dirty or Clogged Carburetor:

If your lawnmower has a carburetor, this component can get dirty and clogged, which can cause the engine to lose power and performance. To clean the carburetor, run the lawnmower for several minutes to warm it up, then turn it off while the carburetor is still warm. Remove and clean the carburetor, or have a professional do it for you.

4. Clutch Drag:

A worn, damaged, or installed incorrectly will result in dragging that can slow down your mower and cause binding. Take your riding lawn mower to a service center where they can diagnose the problem.

5. Obstructed Crankcase Ventilation System:

A clogged, restricted, or damaged crankcase ventilation system will overheat the engine, causing engine power and performance loss. Clean or replace your crankcase ventilation filter as needed.

6. Build-Up of Clippings & Debris:

When left unattended, grass and other debris can build up around the deck and undercarriage components of your riding mower, making it difficult to properly clean and maintain. Remove clippings, debris, and other objects from the mower deck and undercarriage every time you finish mowing.

7. Dirty Air Injection System:

The air injection system provides clean air to the combustion chamber. If the system becomes dirty, clogged, or restricted, it can cause engine power and performance loss. Clean the air injection system as needed.

Directions: How to Make My Riding Lawn Mower Go Faster

Checking the radiator fluid

Step 1:

Use a screwdriver to remove the screws on the gas cap.

Step 2:

Unscrew the air filter and then pull it off of its frame. Wash all parts of the filter for at least three minutes until clean. Use compressed air and shop rags to dry all components (filtering component and frame). Reassemble and replace the old filter with a new one.

Step 3:

Place the lawnmower on level ground and engage the parking brake. Put the locking bar in place or remove the key if applicable to your lawnmower model. Clean grass and debris from the deck, wheels, safety guard, and anything else that may cause harm to you or your property.

Step 4:

Disengage the blade clutch and place one foot on the mower deck. Engage the starter and use a wrench to loosen each bolt just enough for the blade to turn freely by hand. Rotate the blade and check for any excessive wear or damage. Replace if necessary.

Step 5:

Check the radiator fluid. If it is low, add antifreeze to bring it to the proper level.

Step 6:

Release the parking brake and engage the blade clutch. Slowly accelerate your lawnmower until you reach full speed or hear unusual noise or vibration. Stop immediately if any of these situations occur.

Step 7:

After driving the mower for a minimum of ten minutes at full speed, stop the engine and check the oil with a dipstick. If it is low, add more oil until it reaches the proper level.

Step 8:

Disengage the blade clutch and kill the engine. Place one foot on the blade deflector, release the parking brake, and engage the engine brake. Put both hands on the handgrips and slowly increase your speed until comfortable with full throttle operation. If you have done everything correctly so far, your lawnmower should be able to reach its maximum operating speed.

Some Tips and Tricks:

1. Put your lawnmower on a hill so it will roll down the hill and gain speed.

2. Buy shorter grass blades, so they need to be cut less often, thus creating more time for you to drive at top speed.

3. Clean the underside of your lawnmower after each use so that nothing impedes the wheels’ spinning.

4. Change your oil to engage all four wheels at maximum horsepower.

5. Clean underneath your mower, then put Crisco on it, then clean it once more to ensure that there is no resistance whatsoever on the tires of your lawnmower.

6. Find a riding lawn mower with the fastest horsepower rating you can afford.

7. Make sure your blades are sharp to chop grass faster.

8. Gradually lower your yard so that there is less distance for you to drive, thus creating more speed during each journey.

Can You Boost a Riding Lawn Mower?

Boost the Riding Lawn Mower

A basic riding lawn mower will not go faster than about 10 mph. However, those who need to cover larger areas in less time might want to look into ways of how to make my riding lawn mower go faster or into other methods for covering more ground, like a zero-turn radius lawnmower.

Stabilizers are the most common way to make riding lawn mowers go faster. They increase stability, which allows users to cut at faster speeds. Other possible ways of how to make my riding lawn mower go faster include things like chains or loose parts on the underside of the deck that contacts the ground.


So you wanted to know how to make my riding lawn mower go faster. Well, it depends on your needs and desires, but you must check the oil level and air filter. You may also need to change out the spark plugs if they are old or dirty.

You should also get an inspection of the belts of the engine. These inspections can keep your mower running smoothly and help it run at maximum speed when needed!

But if you need something more heavy-duty than can handle rocks and trees and taller blades of grass without slowing down due to clipping height restrictions because of its size, then perhaps looking into purchasing a bigger gas-powered model will be a good choice.
