Buyers Guide

How a mulching lawn mower works

Mulching lawn mowers lift up the cut grass clippings into the bell of the cutting deck and cut them multiple times before returning them to the ground so they can be absorbed into the soil. This requires a blade with multiple cutting edges and enough room in the cutting deck for clippings to circulate. 

Here is a brief video that demonstrates a mulching mower at work:

Gas vs. battery vs. corded mulching lawn mowers

Power is important when it comes to mulching. Keeping the clippings trapped in the cutting deck creates a need for more power to continuously chop through the swirl of grass. This means the power source of your mulching mower should be an important part of your decision-making process.

Gas-powered lawn mowers

Gas-powered mowers are traditionally considered the most powerful option, but it comes at a price. They are much louder, require more maintenance, can be difficult to start, and release pollutants that are both toxic and damaging to the environment.

There are plenty of electric models that can answer the call of duty for mulching. These come in both battery-powered (limited run time and need to recharge) and corded (require a long and durable extension cord) options.

You’ll also need to consider what sort of experience you are looking for when choosing your power source.

Gas-powered mowers get the job done, but they have “starting strain.” You’ll have to pull the recoil cord to start them and that doesn’t always happen on the first few tries.

Weather or other factors can make it very difficult to get your gas mower going. Not to mention the hassles that come with gas and oil machines.

Corded electric lawn mowers

Corded electric mowers are as easy as plug and play. Just grab your extension cord, hook up the mower, hit the start button, and you’re on your way to a freshly mowed yard.

The only downside is that you’ll be tethered to an outlet and might need to do some mid-mow switching to hit every corner of your yard. Don’t forget to avoid mowing over the cord.

Battery-powered mowers

Battery-operated mowers have an advantage: They offer the shortest time from storage to mow. Just insert the battery and go.

The problem with battery-powered mowers is that they don’t run for nearly as long as their gas and corded counterparts. Depending on the size of your yard, you may need two (or even three) batteries to finish the job. 

Batteries often can take hours to fully charge, so that means you will need to plan ahead to make sure you don’t run out of juice with a half-mown lawn.

Although batteries aren’t cheap, many of them are cross-compatible with other tools made by the same brand, which is nice for those who might be loyal to a particular power tool maker.

Push vs. self-propelled vs. riding mulching lawn mowers

How your mower moves and the overall mowing experience are other factors to consider. Here’s your choice: Push mower, self-propelled, or a riding mower. Each has its pros and cons.

Push lawn mowers

Push mowers are the simplest and most maneuverable option. You can move them around freely without worrying about variable speeds or accelerators. Just push or pull the mower where you want it to go. 

A downside of push mowers: The problem is that some push mowers can be heavy. If your yard has hills or is very big, pushing your mower can be a strenuous workout.

Self-propelled lawn mowers

Self-propelled mowers require a lot less muscle to mow your yard. Often referred to as “walk-behind” mowers, self-propelled grass cutters make mowing as easy as a walk in the park. Self-propelled mowers are more expensive than the push variety, and that ease-of-use comes at a cost of less maneuverability. 

Downsides of self-propelled mowers: Rear-wheel drive mowers can be difficult to pull backward, while front-wheel-drive mowers can have poor traction. They’re also known to burn battery life faster than push options.

Riding mowers

Riding mowers are the ease-of-mowing elite. Just sit back and enjoy the ride. They make great options for homeowners with multiple acres of land, especially since riding mowers also have a much larger cutting width.

Downsides of riding mowers: One problem with riding mowers is that they are bulky. Most won’t fit through a standard fence gate, and they need much more room for storage. They’re also more difficult to maneuver around in tight spaces.

Riding lawn mowers aren’t typically a great choice for those with small to medium-sized yards.
