Best Walk-behind Lawn Mower Buyer’s Guide

Walk behind lawn mowers are one of the best handy tools a lawn or garden owner cannot do without. They are designed to save you time and energy in your frantic effort to cultivate a healthy lawn.

Just like other equipment out there, the best walk behind lawn mower will depend on your lawn and garden specifications i.e. the size of your garden, topography of the location and your own physical abilities. To help you streamline your choice, here are some things to consider to help you choose the right walk-behind lawn mower.

1. Deck Size

The deck size of the mower you want to buy is a very important aspect and it describes the cutting area of the lawn mower. The wider the deck size the fewer the passes you need to make to cover a large lawn. However a wide deck size might not be the best if you have sensitive flowers around or the topography of your lawn is not on a level plain surface.

You should also consider that the larger the deck size the harder it is to push behind and maneuver tight corners and spaces. Large deck sizes are more suited for owners of large lawns and gardens. Most push behind lawn mowers have a deck size between 15 and 21 inches.

2. The size of your Lawn

The size of your lawn is a determinant on the kind of walk behind lawn mower you buy. We recommend a 15-16 inch deck size lawn mower to those who have a relatively small lawn.

Opt for an electric or gas propelled lawn mower if the terrain of your lawn is uneven. Most electric walk behind lawn mowers have a strong lithium-ion battery that assists in the operator in propelling the engine.

A self-propelled walk-behind lawn mower is best for those who need to maintain hilly areas. These kinds of mowers do most of the work with little inputs from the operators.

3. Height Adjustment feature

For a healthy grass look, the mower you choose to purchase should have the ability of height adjustments. You should be able to adjust the deck height in incremental steps for a finer grass cut. It is recommended that lawn operators need not cut lawn grass below 30% of the height. Going below this threshold could cause the grass to become brittle and break off during hot weather.

4. Mulching ability

Mulching ability is a useful feature that can cut the work of the operator in half. Mowers can either cut the grass clippings to the side, in a bag or mulch them back into the ground. If you buy a mower that shoots the grass clippings to the side or on the mower then you will need to use a rake to gather the clippings for disposal.

Purchasing a mower that has the ability to mulch grass clipping will save you a lot of time. Some even come with 3 in 1 grass mulching feature that presents you with the ability to either mulch grass clipping on a bag or back to the soil. However, also consider that if the mower mulches the clippings to a bag you will need to continuously stop mowing to empty the bag once it is full.

5. Safety Features

Safety always should always come first in any equipment you use. Electric walk behind lawn mowers can easily be started by turning a key or pressing a button whereas manual lawn mowers need to be yanked at the cord several times before they start.  Electric walk behind lawn mowers is best suited for elderly people and those with severe backache.

Check to see if the mower has speed control features and how ergonomically friendly it is to handle.

6. Warranty

No one expects his lawn mower to last forever but there must be some guarantee that it will work a while before they will need fixing. Long warranty periods are a yardstick for judging the quality of a mower.

A warranty period of 2 years is not very good, especially if the mower will be used on a regular basis. It will do you a lot of good to read the fine print of the warranty period so that you will be aware of what parts are covered and for how long. In some cases, the warranty period of the engine chassis is different from the warranty period of the engine itself.

Finally, good customer support is essential in case things go wrong. Read a lot of customer reviews to have an idea of how the support system of the brand operates. If they are bad, chances are that there will be some complaints about it in the review section.

Types of Walk behind Lawn Mowers

Push Lawn Mowers

Push lawn mowers are ideal for those who own a small lawn and easy to cut grass. The mowers require a reasonable amount of physical exertion to work. If mowing is regular for you, it can become a nice way to get some exercise.

Self-propelled lawn mowers unlike push lawn mowers are either powered by electricity or gasoline. They have a strong motor within their system that does all the hard work. All that is required is a gentle push and a lever to control the direction.

Invest in a self-propelled lawn mower if you have a large lawn to maintain regularly.

Self-Propelled Lawn Mowers

Self-propelled lawn mowers are superior in many ways. Most offer a keyless start with variable speeds by engaging the speed control lever or valve. The speed levers are usually constructed as part of the handle for easy operation or are located as a separate bar you can independently control.

Self-propelled lawn mowers are usually constructed to either be front wheel drives or rear wheel drives. Front wheel-drives are better at navigation, all the operator needs to do is tip the front wheels in any direction he desires. Rear wheels on the other hand, are better at traction and become very useful when mulching is needed.

Self-propelled mowers are a little more expensive than push lawn mowers because of the technology involved. However, most manufacturers now construct lightweight mowers to the extent that you won’t feel the impact of straining your arms with a push lawn mower.

Choosing Between Electric, Gasoline or Battery-Powered Lawn Mowers

Corded Lawn Mowers

Corded or electric lawn mowers are best suited for small lawn and gardens with a fairly even terrain. They have the ability to provide clean cutting power just as does found with gasoline-powered lawn mowers. Electric mowers are easy to maneuver, lightweight, environmentally friendly and safer to operate.

The only downside to electric mowers is that you have to stay connected to a socket grid or you use an extension cord to power the device. Make sure you employ the use of heavy duty cords with electric mowers or else you run the risk of damaging the wires or the machine.

Battery Powered Lawn Mowers

For those who dread the use of corded electric lawn mowers or do not fancy annoying extension cords, the best option outside of gas-powered mowers is battery powered lawn mowers. Battery powered lawn mowers can be used for small to medium lawns and are equipped with long-lasting lithium-ion batteries. Battery propelled lawn mowers can easily be started by the push of a button and some models come with extra batteries to increase mowing time.

Gas Powered Lawn Mowers 

No doubt, gasoline powered lawn mowers are the most powerful lawn mowers in stores today. They do a better job at cutting grass and clearing through long weeds for medium to large lawns and gardens.

The major downside is that they are known for emitting too many fumes, hence are not an eco-friendly alternative. Maintenance is also an issue, they are more costly to maintain than electric or battery propelled lawn mower. You have to change the oil frequently and service the parts.

Although, gas mowers can help you get your chores done quickly, they are the noisiest of the lot.
