How Much Gas Does A Lawn Mower Use?

When it comes to maintaining a pristine lawn, a lawnmower is an essential tool for any homeowner.

But have you ever wondered how much gas your lawnmower uses?

The amount of gas a lawnmower uses can vary depending on several factors, including the size of the mower, the type of engine, and the terrain of your lawn.

For example, a push mower with a smaller engine will typically use less gas than a riding mower with a larger engine. Additionally, if your lawn has a lot of hills or rough terrain, your lawnmower may use more gas to power through those areas.

Understanding your mower’s fuel consumption can help you better budget for your lawn care expenses.

In this article, we will explore the factors that affect how much gas a lawnmower uses and provide some tips on how to maximize your lawnmower’s fuel efficiency.

Whether you are a seasoned lawn care pro or a new homeowner looking to maintain your lawn, understanding the gas usage of your lawnmower is an important aspect of lawn care.

Gas Usage Per Hour Chart

There are many variables, but the chart below should give you a general idea of how much gas a lawn mower uses on average:

Type of MowerGas Usage per Hour
Push Mower0.5 – 1 gallon/hour
Lawn Tractor1 – 2 gallons/hour
Zero Turn Mower2 – 4 gallons/hour

Please note that the gas usage per hour can still vary depending on the specific model and engine size of the mower.

Factors Affecting Lawn Mower Gas Usage

Lawn Mower Type

The type of lawn mower you use can impact how much gas it consumes.

A push mower typically uses less gas than a riding lawn mower, while a self-propelled lawn mower can use more gas than a push mower. This is because self-propelled mowers have engines that are larger and more powerful, which require more fuel to operate.

Engine Size

The size of your lawn mower’s engine can also affect its gas usage. Larger engines tend to consume more gas than smaller ones, as they require more fuel to operate.

If you have a large lawn or frequently mow grass that is thick or tall, you may need a mower with a larger engine to get the job done in a reasonable amount of time.

However, keep in mind that larger engines can also be more expensive, so it’s important to weigh the costs and benefits before making a purchase.

Terrain and Grass Height

The terrain and grass height of your lawn can also impact how much gas your lawn mower uses. If you have a hilly or uneven lawn, your mower may need to work harder to cut the grass, which can result in increased gas usage.

If your grass is particularly tall or thick, your mower may need to run for a longer period of time to complete the job, which can also increase gas consumption.


Proper maintenance of your lawn mower can also impact its gas usage. Regularly changing the oil, air filter, and spark plug can help ensure that your mower is running properly and using gas as efficiently as possible.

Keeping your blades sharp and tires properly inflated (if applicable) can also help reduce gas consumption.

Average Gas Usage for Different Lawn Mowers

Push Mowers

Push mowers are the most common type of lawn mower

They are typically powered by gasoline engines and require frequent refueling. On average, a push mower uses about 0.25 gallons of gasoline per hour of mowing. This means that if you mow your lawn for an hour each week during the mowing season, you will use approximately 13 gallons of gasoline per year.

It’s important to note that the actual gas usage of a push mower can vary depending on the size of the engine, the terrain of your lawn, and the condition of the mower.

Self-Propelled Mowers

Self-propelled mowers are similar to push mowers, but they have an additional feature that allows them to move forward on their own.

This makes them ideal for larger lawns or for people who have difficulty pushing a mower. On average, a self-propelled mower uses about 0.3 gallons of gasoline per hour of use.

This means that if you mow your lawn for an hour each week during the mowing season, you will use approximately 16 gallons of gasoline per year.

Riding Mowers

Riding mowers are the largest and most powerful type of lawn mower. They are designed for large lawns and are often used by professional landscapers.

On average, a riding mower uses about 0.5 gallons of gasoline per hour of use. This means that if you mow your lawn for an hour each week during the mowing season, you will use approximately 26 gallons of gasoline per year.

Tips to Reduce Lawn Mower Gas Usage

Mow at Optimal Times

Mowing during the hottest times of the day can cause your lawn mower to use more gasoline. It’s best to mow early in the morning or in the late afternoon when the temperature is cooler.

This will not only help you save on gas but also prevent overheating of the engine.

Mow at the Right Height

Adjusting the lawn mower blade height to the correct level can help save on gas. Mowing too low (or too fast) can cause the engine to work harder, which uses more gasoline.

Check your lawn mower manual for the recommended blade height and adjust accordingly.

Keep Blades Sharp

Blades that are dull or damaged can cause the engine to work harder than necessary, which can lead to increased gasoline consumption.

Regularly sharpening the blades can help reduce the amount of gas your lawn mower uses over time.

Avoid Overfilling the Fuel Tank

Overfilling the gas tank can cause gasoline to spill out and potentially damage the machine and your lawn.

Fill the tank to the recommended level specified in the manual to avoid overfilling.

By following these tips, you can reduce the amount of gasoline your lawn mower uses. This can save you both time and money while also helping to reduce your carbon footprint.
