Power Source Type: Gas Powered

Cutting Width: 21 Inch



A reliable and effective yet affordable gas-powered lawn mower is the black+decker lawn mower that comes at a great price. The lawn mower works so great by utilising the side discharge clipping of the grass in a manner that the special nutrients that are healthy for the soil are returned back to it.

This lawn mower is great for a medium-sized lawn that covers more surface area and the front and rear wheels are both seven-inches. The cutting measurements are the same as the power smart mower i.e. 21 inches and the engine has a similar 140 cc power.

The construction of the lawn mower is of sturdy steel which is easy to grip on and use. This mower also comes with six different height adjustment settings to help you with gardening. The cutting function is not as powerful but it can be used in small and cornered spaces which are otherwise difficult to mow.

User Feedback

The consumers are satisfied with the overall product design of the gas lawn mower saying that it is lightweight and easy to use yet powerful enough to move around a medium-sized lawn or yard area. The grass catcher can be easily detached from the mower and is easy to clean. Because of the self-propulsion feature, it performs much faster than even the most expensive lawn mowers.

Another 75-year-old consumer mentioned that the lawn mower does not get stuck or slow down even in the wettest and most moist soil. It is quite easy to glide the mower in a back and forth direction even for a person with joint and back problems. The service, oil change, and gas filling functions are super easy too which makes the mower easier to maintain a small to medium-sized lawn.

The mower can be assembled with ease by following simple instructions that come with the mower package. It only requires one pull but with its power, the grass is easily cut and the mulching function is super effective. The only downside is the long cables which might interfere with the grass catcher so they make the mower manoeuvre difficult at times. Overall, the lawn mower is easy to use, effective and adjustable for anyone who wants to use it.

My verdict on the product:

Overall, I think for a lesser price, this gas lawn mower is perfect for small to medium areas of lawn which are typically easier to maintain as compared to the large ones.

How To Maintain Your Gas Lawn Mower

Even if you get a gas lawn mower at a discounted price, you can still make sure it works and lasts as well as its expensive counterparts. Following are some of the considerations that will ensure your lawn mower is well-maintained for years to come.

  • Change Spark Plug

A lot of users may not be familiar with the usage of the engine and may pull on it a little harder which messes up the spark cable that connects to the engine. Due to this, the engine might face starting up issues. Make sure to change it from time to time because over-using the mower can cause the spark plug to be damaged over time or the gasoline build-up may hinder its start-up.

  • Change the Air filter

An air filter is an essential component of the gas lawn mower which is responsible for keeping the impurities out from your mower engine. When a gas lawn mower is started, it is fueled by gasoline which is burned in order to start the engine, as a result, the air filter may become greasy and blocked by the dirt within the system.

It is usually visible when you see the engine releasing blackened fumes or strange sounds. Make sure you change it every three months for smooth functionality.

  • Service

To ensure that the lawn mower lasts longer, you will need to clean it thoroughly to get rid of the clippings of the grass that might hinder the engine’s performance.

Buying Guide

Buying a gas lawn mower is a great investment but most people are intimidated by the diverse set of options available on the market and end up making the worst choice based on false reviews and misleading articles. Following are some suggestions you need to follow for getting a lawn mower:


This is by far the most negative trait of the gas lawn mower that they are not as quiet as you would want them to be because they are powered by gas. But this can be solved or at least reduced to a much tolerable situation by selecting a smaller-sized engine.

Blade measurements:

The measurements of the blade depend on the measurements of your lawn or yard area. If it is quite large, you might need a lawn mower with a bigger blade that covers the entire area in less time. On the contrary, if you have a smaller to medium lawn area, you won’t need a larger blade, anything will do as long as it does not take too long to mow the yard.

Engine specs:

Probably the most important thing you should consider while buying is the engine power of the gas lawn mower. The power will determine the level of exertion needed to use the lawn mower effectively.

Typically, the lawn mowers come with a self-propulsion technology which means you don’t have to invest all your energy trying to use the lawn mower all around your lawn.

This list and buying guide are specially formulated to showcase the two best gas lawn mowers for under 100 dollars which will help you determine what model of lawn mower fits your budget.


Can you adjust the speed of the black+decker lawn mower?

Is it easy to get replacement parts with the power smart mower?
