What’s mulching lawn mower

A mulching mower’s blade and deck are designed to chop the grass multiple times before returning it to the lawn. With a bag attachment, side discharge mowers direct grass clippings to the side.Only the mulching mower leaves finely cut grass cuttings that provide fertilizer and shade for the soil. This type of mowing is called “mulch mowing.”

How does a mulching mower work?

A ride-on mower mulches leaves on a large lawn.
Mulching mowers are similar to other mowers. Lift is required in all lawn mowers (push, ride-on, etc.) to keep the grass vertical while cutting.

Mowing with a mulching mower not only directs grass into the blades, but also hits the clippings multiple times before returning them to the lawn. Other mowers send the clippings to the side or into a bag.Sure, it’s intentional. Mulching blades have curved edges for extra cutting action and generally have more cutting surface area.A mulching blade is an all-purpose blade that can be used to mulch, bag, or side discharge. Standard blades are 2-in-1 because they can bag or side discharge grass.

Can I use my current mower to recycle my grass clippings?

Yes. Inquire with your local lawn mower retailer (or with the manufacturer of your lawn mower) to determine whether you require a conversion kit. These mulching kits may include a plate (also known as a mulching plug) to seal off your discharge opening (or bag opening) as well as a new blade for your mower. Alternatively, you may only require a new blade.

Push mowers and ride-on mowers are both capable of reintroducing grass clippings back into the lawn. Close your discharge chute or take the bag out of the machine and you’re done. A mulching mower blade, on the other hand, performs better because the pieces are smaller and will decompose more quickly in the lawn.

How to use a mulching mower

Just like any other mower, use it as you would. To ensure that your mulching mowing sessions are a success, here are a few lawn care tips:

Don’t mow in the rain. Weight and tendency to clump make it more difficult for mowers to cut grass blades as finely as they normally would. In addition, your lawn mower’s underside will be splattered with wet grass.
Mow frequently. Mow the lawn according to the golden rule: A single mowing should remove no more than a third of the grass blades.
Cut your lawn at the proper height. It’s hard to believe, but following this simple advice can have a significant impact on the appearance of your lawn. At a certain height, each type of grass performs best. Many soil and grass scientists spend a lot of time and effort at grass test plots trying to figure this out.
Your mowing height may also be affected by the time of year. During the hottest months of the year, some experts recommend mowing a half-inch higher, while the first and last cuts of the season call for a cut that is an inch shorter. Snow mold can be prevented by mowing as low as possible on the final mowing in areas where it snows.

Ask your local Cooperative Extension office for the best seasonal advice.

Consider how dense your lawn is. Your mower may have to work harder if your lawn is dense. If you’re in the market for a new lawn mower, make sure you get one with enough power to meet your needs. You’ll pay for it later if you cut corners here.
It’s important to keep your blade razor-sharp. A well-maintained lawn is impossible to maintain without a sharp mower blade. It’s better to cut with a sharp mower blade rather than a torn one, which can spread disease. Sharpen the blade with a file, hand grinder, bench grinder, or drill attachment with a sharpening stone.

How often should you re-sharpen your mower’s blades? Your lawn’s density, type of grass, and frequency of mowing are all factors to consider. This is a simple test: It’s time to cut the grass if the tip of the blade appears torn rather than cleanly cut. You may need to sharpen your blade as frequently as once a month if you have a dense lawn with stiff-bladed grass such as Zoysia.

Maintain a spotless work surface. At the end of each mowing session, hose off the clippings that have fallen on the deck. The clippings may not circulate properly if gunk accumulates on the underside of the deck.
Mulching is important.
What’s the big deal about mulching or not mulching grass? A healthy lawn is not the only benefit that mulched clippings have to offer.

One reason cities are jumping on board is that grass clippings generate a significant amount of waste. As stated by the Connecticut Department of Energy and Environmental Protection, a half-acre lawn can produce “260 bags of grass clippings” per year, which works out to more than three tons of waste.

Educating residents about the advantages of reusing grass clippings in the lawn and lowering the amount of garbage dumped in landfills is also in their best interests, as you can see.

It’s safe to say that mulching, also known as “grasscycling,” has numerous advantages.

Time is saved (no more raking fall leaves)
Money is saved (free fertilizer, no garbage fees)
Protects the natural world (no grass clippings in streams or landfills)
Erosion is lessened (helps keep the soil in place)


1. Are there any times I should not mulch in my clippings?

Yes, there are times when it’s best not to mulch grass clippings.

—If you have a fungus on your grass, don’t mulch in these lawn clippings. That would only spread the disease.

If you have weeds that are going to seed, bag them and put them in your yard waste bin. You don’t want to aid weed seed redistribution.

If your lawn has over 50% leaf coverage, you may want to bag as you mow. Too much leaf litter and grass mulched into the lawn can harm it. After that, either compost the leaves/grass mix or use it to protect your flower beds from the winter.

2. Other benefits of using a mulching mower:

—No worries about disposing of your grass clippings —No bag to deal with on the lawn mower
•Fertilize and mowing can be done simultaneously •
Refrain from depositing valuable nutrients and moisture into the landfill

3. Will the clippings contribute to the thatch in my lawn?

No, cut grass clippings do not contribute to lawn thatch. Thatch is a layer of dead and living organic matter that accumulates between grass and the soil.

Your lawn is fine if the thatch is less than half an inch. If it exceeds that level, you may want to consider dethatching or aerating (which will inevitably remove some of the thatch). (Aeration is pulling plugs from the soil to improve air, water, and nutrient circulation. This promotes deeper, stronger roots and a greener, healthier lawn.)Contact one of our local lawn care professionals to have your lawn mowed and fertilized (with your grass clippings or store-bought fertilizer). They’ll help your lawn grow greener and fuller.
