How Mulching Mowers Work
The purpose of a mulching mower is that grass clippings left behind will function as a lawn fertilizer, the same as when you distribute the compost onto the lawn. Because of this reason, it is more understandable that most urban and suburban homeowners use a mulching mower, rather than bagging up the grass clippings and leaves after mowing and dumping them in the compost pile. Basically, mulching mowers eliminate the need to collect the leftover from mowing and having to carry those to the compost pile, and instead providing you with compost immediately. This reduces both the time and effort needed for your yard work.
The blades on the mulching mowers are specially designed in order to leave behind very finely shredded grass clippings. These clippings can be left right where they fall, without causing harm to your grass. This is a way more convenient approach to mowing the lawn, but remember to cut your grass at the right height.
On the other hand, since lawn mowers without mulching capabilities produce clippings that are bulkier and have the tendency to clump together, these clippings need to be removed from the lawn, so that the grass does not suffocate under them. This is the reason why people using neither a mulching mower nor a machine with a bag attachment (meaning that the clippings simply blow out of the chute and onto the lawn) have to rake up their lawn clippings. While this third alternative is surely a possibility, it would also be the most labor-intensive approach. Of course, when folks cut the grass with reel mowers, there is not much choice.
Types Of Mulching Mowers
Push mowers can be powered by either gas or electricity, and are categorized as a ‘walk-behind’ mower, meaning they are controlled by a person walking behind them. A lot of these mowers include a 3-in-1 feature that allows side-discharge, bagging, and mulching at the same time. The price of these push mowers are usually on the lower end for all lawn mowers, and the electric type costs a bit more than gas mowers:
- Gas push mower: Gas mowers have the power and mobility to be the suitable choice if your yard is up to an acre in size. Most can be started with a pull-start, but some models can upgrade it to an electric starter, which will be more convenient and eliminate the need to use the pull cord. Take notice that gas mowers will require the right fuel for operation, so make sure to follow the manufacturer's requirements and search for instructions on how to keep your machine running properly.
- Electric push mower: A cordless electric mower can have the capabilities matching with a gas mower, including self-propelled options. They usually ignite with a switch or a push of a push button, and usually are quieter, run swifter than gas ones of the same purposes. These mowers come with multiple different battery types and voltages — the higher the voltage, the more power output from the battery. Their charge times will vary by battery and charger, ranging from 30 minutes (with quick-charge batteries) to a few hours. As the electric mower technology matches up to the gas-powered models, it is important to check for the cut width, battery life and additional features when choosing the best mulching lawn mower for your yard. The models with cord don't require charging after use, therefore they can have unlimited runtime. However, the power cord will restrict the area you can move your lawn mower, so this will prevent you from mowing large lawns or those with obstacles like trees or fences. If you want to mow these types of lawn with a corded mower, it will require you to buy an extension cord.
Self-propelled mowers are also in the walk-behind mowers category like push mowers. These lawn mowers use their motors to propel themselves forward, with you walking behind and guiding it in the right direction.
Self-propelled mowers can also be either electric or gas powered. They typically cost more than push mowers. While traditional push mowers are a suitable choice for many lawns, a self-propelled mower is great if you have a lawn larger than 1/2 acre, on a mountain/hill area or want to mow your lawn with less effort.
There are three types of self-propelled mowers that work for different types of land. The rear-wheel drive (or RWD) models are ideal for bagging because the added weight in the back helps traction. In contrast, for front-wheel drive (or FWD), it’s the opposite as the weight in the back hurts traction:
- FWD mowers are good for flat terrain. With the drive wheels in the front part of the mower, they will help you turn and redirect the lawn mower easier.
- RWD provides more traction at the center of the mower, helping you mow a more hilly yard, and with less effort.
Lawn tractors are mowers that you can ride on. They feature most of the capabilities of lawn mowers. These powerful mowers can take the work out of mowing a large lawn, and are very easy to operate. They’re great for large properties and for users who don’t want the hassle of pushing a heavy gas mower across their grass. Most lawn tractors are gas-powered, and cost significantly more than walk-behind mowers.
Zero turn radius ride-ons
A higher-cost ride-on mower is the zero turn radius (ZTR) mower. It’s basically a ride-on lawn mower that has a turning radius of zero inches, which allows for extreme maneuverability and control. Across brands and models, zero-turn mowers are configured differently.
Which Mulching Lawn Mowers You Should Choose For Your Lawn Sizes
Another aspect that you also need to consider when choosing the best mulching lawn mower is the size of your lawn, as well as the landscape and terrane of the yard you need to mow. Every lawn is different, but here are some general ideas to help you find the best mulching lawn mower ideally for your lawn. If your lawn side is:
- 1/4-acre or smaller: consider either a corded electric or a gas mower.
- 1/4-acre to 1/2-acre: consider a gas or cordless electric model. Corded mower may also be an option, but it will depend on the location of power outlets, and you might need to buy an extended cord.
- 1/2-acre to 1-acre: consider a cordless mower or a gas mower. A self-propelled mower would be more suitable for a lawn this large.
- 1-acre or larger: consider a ride-on lawn mower
You should also take these factors into consideration:
- If your landscape is uneven, a rear-wheel-drive (RWD) self-propelled mower is more ideal.
- If your yard has obstacles, you'll need one with easy navigation, so consider a mower with high rear wheels.
What To Look For In The Best Mulching Lawn Mower
To get yourself the ideal mulching results using the best mulching lawn mower, it is necessary to purchase a ‘proper’ mulching mower with a specific deck dedicated to mulching. Carefully designed mowers will reuse grass far more efficiently than regular gathering trimmers that are later changed over to mulching mode using a mulch-plug. The explanation behind this is in the cutting deck design.
The deck of a good recycler is efficiently planned on the underside to make the air – and the grass cuttings suspended in the air - travels in two ways. Simultaneously as the air and grass clippings move a rotational way around within the deck, they likewise travel in a vortex which permits the grass to go through the cutting cycle multiple times.
Eventually, both the air and the mulched grass particles are released from the cutting deck with pressure, whereby the mulched particles of grass are forced into the base of the turf. It is in the base of the turf where the particles are broken down by microorganisms and transformed into beneficial nutritions for your yard.
In addition to specially designed cutting decks, mulching mowers also feature a specially designed blade, usually with double edges, which further upgrade the under-deck dynamics and chopping performance.
An increasing number of manufacturers are making independent mulching machines, a considerable lot of which are equipped with a side-release chute in case the cutting conditions are too rich and heavy for quality mulching. These machines can frequently be used as rough ground mowers as well, ideal for plantations and messy borderlines.
Conclusion: My Top Pick For Best Mulching Lawn Mower
Purchasing a lawn mower that has the ability to mulch the grass clippings has some great advantages. This type of lawn mower is becoming even more popular, as people desire to adapt a more environmentally friendly lifestyle by reducing carbon footprint and chemicals.
Therefore, choosing the best mulching lawn mower will not only reduce the time and energy to mow your lawn, but also keep your yard beautiful and fresh from season to season.
Based on careful reviewing, we are happy to present to you the best mulching lawn mower options for you to select based on your preference.
