Why Does Lawn Mower Slows Down When Cutting? 6 Superb Reasons Why It’s Happen

Why lawn mower slows down when cutting? Lawn mowers are one of the most common tools for cutting grass in residential areas. They are used by many people to maintain the perfect manicured lawn. However, you may notice that lawn mowers slow down when cutting. Why is this? Read this article until end to know more about it. In this blog, we also have an article about best high end lawn mowers that you might want to read about it.

Why Does Lawn Mower Slows Down When Cutting

While you may not encounter such issues while mowing on flat ground, when mowing on an incline or slope, the mower may splutter and sometimes lose power when the blades are engaged.

Thus, although the circumstances may differ slightly, the motivations are essentially the same.

Once you understand why something is occurring, you may take steps to resolve the issue. The following are the most typical causes of power outages and how to resolve them:

Exceedingly Dirty

Even if the unit is brand new, dirt and grass might block the air filter system or cooling fins, resulting in power loss. When there is a power outage, a mower bogs down in dense grass. The rationale is rather straightforward.

The engine will overheat as a result of insufficient air and diminished cooling capacities. As a result, it’s unsurprising that the mower would bog down under load.

You should also inspect the fuel system for excessive dirt and dampness. There will be a build-up of dirt and water in the carburetor, resulting in inefficient combustion. Inefficient combustion results in sputtering and, eventually, engine failure.

Fortunately, resolving the issue is rather simple. Clean the cooling fins completely. Additionally, replace old gasoline with fresh oil.

Concern Regarding Capacity

If you exceed the mower’s capacity, it will bog down. Perhaps your hillside lawnmower is capable of cutting grass on flat land but you wish to trim uphill grass – even a zero turn mower will lose power when the blades are engaged.

Alternatively, if too much weight is placed on it when cutting uphill grass, the same thing may occur.

Occasionally, it is just the dense or tall grass that causes the bog down, since the mower is not designed for it.

Whatever the cause, if your lawn mower begins to bog down, remove some weight from it and inspect the mower’s capacity.

Inadequate oil level

Both much and insufficient crankcase oil contribute to the zero turn mower’s power loss. When the oil level is low, there is insufficient oil to lubricate all of the engine’s working components.

If it is too high, more air will enter the lubricating system as a result of the foamy oil. Both possibilities will result in a brief loss of power or a longer loss of power.

Deficiency of Constant Spark

Due to a variety of factors such as carbon, dirt, gasoline, and oil, the spark plug becomes coated over time and is unable to ignite continuously.

As a consequence, the mower’s ignition will be intermittent, and the mower will lose power. If your mower is not performing properly, you should immediately inspect the spark plugs.

A defective spark plug is simple to examine and replace. You may also clean it.

In Blades, There Are Dirts & Debris

When mowing uphill with an older mower, considerable dirt and corrosion might result in an abrupt loss of power. Dirt and debris might also be blamed for the push mower bogging down.

It’s unsurprising that your mower would work harder when debris such as muck and grass coats the blades.

Due to the reasons stated above, your mower will lose power while the blades are engaged. Fortunately, this is a simple repair. Simply clean the blades of any buildups.

Muffler Clogged

Through the muffler, your mower exhausts burnt gas and other gasses. Over time, various substances and debris may block the muffler.

This is the point at which things get serious. Due to the fact that no burnt gas is escaping, your mower’s engine may eventually seize.

However, how can you determine if you have a blocked muffler?

To be honest, it’s rather simple to look at. If you observe any colored smoke emanating from the mower, you most likely have a blocked muffler.

To avoid this issue, just clean the muffler at the start of each season.
