Can Lawn Mowers Remove Dead Grass? Let’s Find Out

While dealing with thatch isn’t an uncommon problem, it can be particularly challenging for Michigan homeowners who prefer thick grass types. Oftentimes, these grasses are used to give lawns a lush, full appearance. 

However, maintaining this look can be difficult if dead grass prevents new growth from occurring. To combat this, some homeowners mow their grass more frequently, as it’s believed that mowers can remove thatch. But is this really the case? 

So, Is Thatch Actually Removed During the Mowing Process?

Yes, thatch can be removed by mowing your lawn. However, only the top layer is actually removed during the mowing process. Oftentimes, the top layer of thatch is loose and can be easily picked up by the blades. While this does provide some benefit, not all the dead grass is removed. 

Mowers aren’t equipped to remove the deeper, thicker layers of thatch that remain under freshly-cut grass. While it may appear that all of the dead material has been removed, this is likely not the case. 

How To Remove Deep Layers of Thatch

There are several ways to remove thick layers of thatch, some of which are:

• Manual detaching – This method involves using a dethatching rake to pull up the layer of thatch by hand. It’s best for small areas or lawns with minimal thatch buildup.
• Power mowers and vertical rakes – These motorized tools use rotating blades or tines to cut through and remove thatch efficiently. They're ideal for larger lawns or moderate to heavy thatch layers.
• Liquid dethatchers – These products use enzymes or microbes to break down the thatch naturally over time. It’s a low-effort option that works best when used consistently as part of a lawn care routine.

Potential Downsides To Thatch Removal Techniques

While dethatching can promote healthy grass growth, it must be done correctly to avoid future problems. If done at the wrong time, or if your lawn doesn’t receive proper aftercare, it may be at risk for:

• Lawn damage – Thatching too much or using the wrong equipment can tear up healthy grass. This can leave bare patches and make the lawn more vulnerable to pests and disease.
• Increased weed growth – Removing too much thatch at once can expose the soil, creating open spaces where weeds can quickly take hold. Without proper lawn care afterward, invasive species may outcompete your grass.
• Alter the lawn’s ecosystem – Thatch plays a role in retaining moisture and providing insulation for soil microbes. Disrupting it too severely can throw off the balance of beneficial organisms in your lawn.

Preventing Damage to Your Lawn

To prevent damage to your lawn, thatching should be done in late summer or early fall. With less heat during this season, grass has a better chance of recovery. Plus, the additional rain that falls during this time of year can improve your lawn’s health. 

It’s also important that you give your lawn proper aftercare following deep thatch removal. This includes frequently watering your lawn, providing it with adequate fertilizer and overseeding it to help fill in bare spots. With these efforts, there’s less chance that your lawn will sustain any long-term damage resulting from thatching. 

For Best Results, Consult a Professional

If you’re considering a deep thatch removal, it's recommended that you seek help from a lawn care expert. Lawn care technicians have the tools and experience needed to successfully remove thatch without damaging your lawn. 

Plus, thatch removal is very labor-intensive and can take lots of commitment to achieve the best results. Having a trained technician remove your lawn’s thatch will not only save you time and hassle, but will prevent possible damage, leaving your lawn looking and feeling healthy all season long.
