What Does Dog Poop Do To A Lawn Mower?

Dog poop can clog the blades of your riding lawnmower. If you run over dog poop with your riding lawnmower, it may damage the engine of your machine.

When using a lawn mower, it’s easy to accidentally damage it without even realizing it. Check out our article on Can You Break a Lawn Mower? My Experience to learn about different ways a lawn mower can break and how to avoid them.

Can A Lawn Mower Break If It Runs Over Dog Poop?

Yes, it can break the lawn mower. It depends on what kind of dog poop and how fast your lawnmower is going. If the dog poop is small enough, it can get stuck in the blades and cause them to break or bend over time. 

If you have a large breed dog that leaves large droppings (think Great Dane), then yes, running over one with your lawnmower could very easily break the blades. The best thing you can do is rake up your yard before mowing so that no feces are left behind to cause damage!

How Much Weight Can A Lawn Mower Hold?

You might have wondered how much weight a riding lawnmower can hold. While there are many different machines with different capabilities, the answer is generally around 200-500 pounds depending on the type of mower and its size. 

You may be wondering where these numbers come from and why they differ so much from one another. The answer lies in the structural design of each machine; some are built to carry more than others, but all should be able to hold at least 200 lbs without breaking or other serious damage occurring (though this does not mean that you should ever overload your machine).

Mowing a wet lawn can cause a lot of inconvenience and, in some cases, even harm the lawn mower itself. Our article on Can Wet Grass Break a Lawn Mower? Landscape Advice highlights the reasons why you should avoid mowing a lawn when it’s wet.

Can Dog Poop Break The Engine Of A Lawn Mower?

Your lawn mower can break if you run over dog poop with it.

Dog poop contains a lot of water, which will make the engine work harder than normal and could cause it to fail. If your cutting deck has a bag on it, then you should be fine as long as dog feces doesn’t get into the bag and onto the blades. 

If there is no bag on your mower, then try not to run over too much at once or else you may end up needing a new engine!

What Happens When You Run Over Dog Poop With A Riding Lawn Mower?

The good news is, your lawnmower will not break if you run it over dog poop. With a regular lawn mower, there are two different types of blades: mulching blades and side discharge blades. The mulching blade is used to cut grass into small pieces that are then left on the lawn as fertilizer. 

If you have a mulch kit installed on your mower, those blades can handle most things including dog poop. Side discharge blades are used for when you want the grass clippings to be collected in a bag behind your machine and thrown away at the end of each use like when you’re fertilizing larger areas of land (which we’d recommend doing before cutting). 

If neither one of these options sounds like what will work for you, don’t worry; we’ve got some other solutions!

With unpredictable weather conditions, at times, a lawn mower gets rained on. So, what happens in such a scenario? Our article on Can Lawn Mower Get Rained On? Landscape Advice discusses the impact of rain on a lawn mower and how to protect your equipment from potential damage.

Will Your Lawn Mower Break If You Run Over Dog Poop?

Many people are concerned that if they run over pet waste with their lawnmower, the blade will get clogged up and eventually break off. However, this is not true.

The reason why many people believe this myth is because they think that the blades of your lawnmower are made of metal and therefore cannot be broken. 

In reality, though, most riding lawn mowers have a steel deck that makes up their entire body. This means that your blade will not break when it hits dog poop because there isn’t anything to break!

How Long Will It Take My Lawn Mower To Break If I Run Over Dog Poop?

The amount and size of dog poop that you run over with your lawn mower will determine how long it takes the engine to stop working. If the dog is small, then running over its feces is unlikely to cause any damage because these animals produce small amounts of waste. Large dogs can produce large amounts of waste, however, so if you have one or more large dogs living in your neighborhood, this could pose a problem. 

The size and weight of your riding lawn mower will also play a part in determining whether or not it will break down from running over dog poop with it. 

A smaller riding lawn mower may be less likely to break than a larger one given that there’s not as much weight pressing down on them when they are moving around while doing their job (i.e., cutting grass).

Does Running Over Dog Poop Damage Your Riding Lawn Mower?

Yes, dog poop can break a lawn mower. But it’s easy to avoid this issue if you’re careful: never let your dog run wild in the yard or garden where you keep your equipment and make sure all the grass has been cut short so that there are no long blades of grass between which he could get stuck. 

If this does happen, clean up immediately and rinse with water from a hose before drying with a towel (or perhaps even use compressed air).

Operating your lawn mower for too long can cause overheating, resulting in significant damage. Our article on Can Lawn Mowers Overheat? My Experience sheds light on the causes of overheating and how to prevent it from happening.

Will My Riding Lawnmower Break If I Run Over Cat Or Dog Feces With It?

Yes, your riding lawnmower will break if you run over cat or dog feces. There are several different types of riding lawnmowers that can be damaged by this maneuver:

Riding Lawnmowers with a plastic deck – If your mower has a plastic deck and you run it over cat or dog feces, it will be damaged beyond repair. Cat and dog feces are full of bacteria that can eat through the plastic decks on these types of machines in no time flat!

Riding Lawnmowers with steel decks – If your mower has a steel deck and you run it over cat or dog feces, it may not suffer any damage at all (depending on how much weight was in the bag when you ran into it). 

However, if there is enough weight from either animal waste or mulch to bend one of its blades a very common occurrence for many reasons you will probably have to replace multiple parts before getting back out there again

What Happens When You Run Over Cat Or Dog Feces With Your Riding Lawnmower?

You should avoid running over cat or dog feces with your riding lawn mower. Cat and dog feces can clog up the blades of your mower, and will cause the engine to overheat. Cat and dog feces can also cause the engine to break down.

How Much Does It Cost To Repair A Broken Riding Lawnmower From Running Over Cat Or Dog Feces With It?

It depends on the brand of lawnmower, but most brands charge between $100 and $200 for a service call. If you have a riding lawnmower, it will cost more to repair than a push mower because there are more moving parts in the engine that could break when running over cat or dog feces.

When using a lawn mower, it is critical to take precautionary measures to protect your hearing. Our article on Can a Lawn Mower Cause Hearing Damage? Landscaper Advice explains the risks associated with lawn mower use and provides safety tips for protecting your hearing.


Running over cat or dog feces with your riding lawnmower can be a costly mistake. Even though it might seem like the right thing to do, it is not worth risking thousands of dollars in repairs because you just couldn’t stand the thought of leaving pet waste on your property. If you have an area that needs cleaning, use a rake and shovel instead!
