How to Adjust the Speed on Your Lawn Mower?

There’s nothing more frustrating than trying to tackle your lawn with a mower that’s either too slow or too fast. You end up with uneven cuts, a sore back, and a yard that looks more like a battleground than a peaceful oasis. But fear not, lawn care warriors! This guide will equip you with the knowledge to conquer the speed demon of your mower and achieve a perfectly manicured lawn. We’ll delve into the common types of mowers, identify the key speed-related components, and outline the steps for adjusting the pace of your mowing machine.

Understanding Your Lawn Mower

The ability to adjust the speed on a lawnmower hinges on the type of mower you own. Most modern mowers fall into two primary categories: self-propelled and push mowers. Self-propelled mowers, as their name suggests, utilize an engine to assist the user in moving the mower. Push mowers, on the other hand, require manual effort. Let’s break down the speed adjustment process for each.

Self-Propelled Mowers: Harnessing the Power

Self-propelled mowers offer a range of speed options, allowing you to tailor your mowing experience to your needs and the terrain. Here’s a step-by-step guide to adjusting the speed on a self-propelled lawnmower:

Identifying the Speed Control

The speed control mechanism varies depending on the manufacturer and model, but it’s typically found in one of these locations:

1. The Handlebar:

Often, a lever or button on the handlebar itself controls the speed. This lever might be marked with “slow,” “medium,” or “fast” or could have a numerical scale.

2. The Drive System:

In some models, the speed adjustment is located near the wheels or the drive system. This could be a lever, a knob, or a series of gears.

Adjusting the Speed

  1. Locate the Speed Control: Refer to your mower’s manual for the exact location of the speed control.
  2. Adjust the Setting: Based on the type of speed control mechanism, you’ll need to either:
    • Move a lever: Gently shift the lever in the desired direction to increase or decrease the speed.
    • Turn a knob: Rotate the knob clockwise to increase speed and counterclockwise to decrease speed.
    • Change gears: If your mower has a gear system, shift the gears to select the desired speed.
  3. Test the Speed: Once you’ve adjusted the speed, test it out in a small section of your lawn.

Push Mowers: Fine-Tuning Your Pace

Push mowers, while seemingly straightforward, also offer some degree of speed control. However, their speed adjustment mechanisms are more about finesse and less about having a multitude of speed options:

Mastering the Push Mower’s Speed

  1. Smoothness and Consistency: The key to adjusting the speed of a push mower lies in the smooth and consistent pressure you apply to the handle. The more pressure you exert, the faster the mower moves.
  2. Ground Conditions: Remember that the speed you maintain will also be affected by the ground conditions. Soft, uneven terrain will naturally slow you down, while hard, smooth surfaces will allow for faster movement.

Beyond the Basics: Troubleshooting and Maintenance

While adjusting the speed is often a simple fix, there are some instances where issues may arise:

1. Engine Problems:

A sluggish engine could be hindering your mower’s speed. Here are some common engine-related culprits:

1. Fuel:

Old or contaminated fuel can cause engine problems. Try draining the old fuel and refilling with fresh, high-quality gasoline.

2. Air Filter:

A clogged air filter can restrict air intake, leading to poor engine performance. Clean or replace the air filter regularly.

3. Spark Plug:

A faulty spark plug can hinder ignition. Inspect and replace the spark plug as needed.

2. Drive System Issues:

Problems with the drive system in self-propelled mowers can also affect speed.

1. Belt:

A worn, loose, or broken drive belt can prevent the wheels from turning properly. Inspect and replace the belt as needed.

2. Drive Gears:

If the drive gears are damaged or worn, they may not engage properly, affecting the speed. Inspect the gears and consult a repair professional if necessary.

3. Maintenance is Key:

Regular maintenance is crucial for optimal performance and to prevent speed issues. Here are some important steps:

1. Oil Change:

Change the engine oil according to the manufacturer’s recommendations.

2. Blade Sharpness:

Sharp blades are essential for smooth and efficient mowing. Sharpen or replace the blades regularly.

3. Cleaning:

Keep the mower clean and free of debris, especially in the engine compartment and around the drive system.

Adjusting Your Mowing Technique: A Harmonious Pace

Apart from the physical adjustments, there are mowing techniques that can help you find a harmonious pace:

1. Walking Speed:

Walking at a steady pace will generally translate to a consistent mowing speed.

2. Overlapping:

Slightly overlap each mowing pass to ensure even cutting and avoid scalping the lawn.

3. Terrain Awareness:

Be mindful of terrain changes. Slow down when going uphill and increase speed on flat sections.

Conclusion: The Perfect Pace for a Perfect Lawn

Adjusting the speed on your lawn mower isn’t a complex process. Whether you’re using a self-propelled or push mower, understanding the specific mechanisms and practicing a few simple techniques can make a world of difference in your mowing experience. With the knowledge you’ve gained from this guide, you can now confidently navigate the world of speed adjustments and achieve a perfectly manicured lawn, all while leaving your back feeling happy and your yard looking pristine.


1. How do I know if my lawn mower has a speed adjustment?

Not all lawn mowers have speed adjustments. Some models only have one set speed. To see if yours has an adjustable speed, look for a lever or knob near the engine. If you see a lever or knob, it’s likely that you can adjust the speed. If not, your mower might have a single speed.

2. Why would I want to adjust the speed on my lawn mower?

You might want to adjust the speed on your lawn mower for various reasons. If you have a large lawn, you may want to use a faster speed to cover the ground more quickly. On the other hand, if you have a small lawn or are mowing in tricky areas, a slower speed might be more beneficial. A slower speed also allows for a more precise cut, especially around obstacles.

3. How do I adjust the speed on my lawn mower?

The specific process for adjusting the speed on your lawn mower will vary depending on the model. However, in general, you will need to locate the speed control lever or knob. This is often located on the side or near the handle. You can then move the lever or turn the knob to increase or decrease the speed. Consult your owner’s manual for precise instructions specific to your mower.

4. What happens if I adjust the speed too high?

Adjusting the speed too high can cause problems. Your lawn mower may vibrate excessively, making it difficult to control. It can also damage the engine by forcing it to work harder than it was designed to. Additionally, a higher speed can lead to an uneven cut, resulting in a patchy lawn.

5. What happens if I adjust the speed too low?

If you adjust the speed too low, your mower might struggle to cut through thick grass. This can result in a patchy lawn and potentially damage the engine. You might also find yourself pushing the mower harder, which can be tiring, especially if you have a large lawn.

6. How often should I adjust the speed?

You don’t need to adjust the speed of your lawn mower very often. Typically, you can use the same speed for most mowing sessions. However, if you are mowing in different conditions, like taller grass or thicker patches, you might need to adjust the speed. Also, if you are mowing around obstacles, you may want to slow down.

7. Can I adjust the speed while the engine is running?

It is generally not recommended to adjust the speed on your lawn mower while the engine is running. This can be dangerous and could lead to injury. Always stop the engine before making any adjustments to the speed. Consult your owner’s manual for specific instructions on speed adjustment for your model.
