Can Robotic Lawn Mowers Cut Long Grass?

Many people prefer to keep the lawn clean and healthy by using robotic mowers to cut the long grass.

Can Robotic Lawn Mowers Cut Long Grass? According to our experience, Robotic lawn mowers can cut long grass as they are efficient in cutting leaf blades 8 to 10 inches taller. These robotic mowers can reduce the grass size within 2 to 3 hours of continuous working and keep your tall grass at an ideal length of 2.5 to 3.5 inches. You can use these by checking the grass conditions, adjusting its height, start cutting in directional motion, and sprinkling water after the cleaning process.

Tall grass can facilitate many bugs to grow inside that can sting on your feet when you enjoy a morning walk or children are playing on the ground.

It is essential to mow long grass to improve its growth by providing better exposure to sunlight and air and preventing fungus growth.

What are robotic lawn mowers?

Robotic lawn mowers are automatic machines that are used to cut tall grass. These get power from rechargeable batteries made of lithium-ion or lead acid.

You have to plug a charging wire into an electrical outlet present outdoors. Then, it can move to the outlet automatically when the charging ends.

Moreover, it can clean a large surface area by cutting large blades with a sharp cutter in a few hours. You have to set wire around the lawn perimeter to keep it within a boundary. This tool is famous to cut grass.

What should be the ideal length of grass?

The length of grass varies according to its type and the area’s environmental conditions. Most commonly, grass length is 2 to 3.5 inches for a lawn.

Different types of grasses have variable heights; Bermuda grass is 0.5-1.5 inches long, while a centipede is 1.5 to 2.5 inches tall.

In addition, perennial ryegrass and fine fescues are almost 2 to 3 inches and 2.5 to 3 inches long.

Moreover, it can keep your soil cool and withstand the drought stress due to longer roots when it is more than 3 inches in height.

However, tall grass can allow the fungus to grow by providing a cool and moist environment, so you have to maintain it at a good height that allows air to reach the bottom of the plant.

An extensive root system and wider blades ensure better photosynthesis and allow them to produce more food, so ideally, keeping your grass at a length of 2.5 to 3.5 inches is better.

Why would you use robotic lawn mowers to cut long grass?

You can use these mowers to trim the grass to give a refined look to the yard to make your children play safely.

Tall grass can allow bugs to remain inside that can sting on your feet, so it needs to be cut to reach an ideal height.

It can not only cut small blades of 2 to 3 inches but can also work efficiently on larger ones with 8 to 10 inches in height.

It is possible due to its height adjustment feature that can be increased or decreased according to the conditions.

Accordingly, it provides better coverage of the area and cleans almost 2 acres of the yard within a few hours when you are enjoying snacks by sitting on a bench in the corner of a yard.

However, you have to use a weed trimmer to reduce the size of 8 to 10 inches of tall grass and make it around 4 to 6 inches before using a mower.

It can get stuck within taller ones when you do not use a weed trimmer before starting mowing, which can damage it.

There is a chance of hitting a foreign and rigid object that can be present within higher blades of the plant, so you have to make them short enough that they can handle the cutting procedure efficiently.

How do you cut long grass with a robotic lawn mower?

You can trim the grass size by using a robotic lawn mower in a few easy steps, allowing it to move on the ground after inserting the wire in the switch.

Check the conditions

You have to check the condition of the soil before starting the mowing process, as rain and dew drops can make it wet.

The wet blades can accumulate together, forming a bigger mass that can get stuck in the mower and clog. In addition, it puts stress on the motor and makes it non-functional.

It is better to wait for its drying because wet blades can bend over, which can be responsible for uneven cuts.

Measure grass height

It is essential to measure its height in inches using a measuring tape. It can help you decide about the strategies that can be adopted to cut it down because tall grass needs weed trimming before the cutting process.

These mowers can cut even 8 to 10 inches higher plants, but you can use a trimmer to minimize the stress on its structure.

Adjust the lawn mower height

Increase the height of the lawn mower to a maximum that is not so much different from other conventional mowers.

You can easily find an adjustment knob on the side or bottom of the machine. In addition, you can make changes in height through a display by following the instructions in the manual.

You have to set a lower and higher range that allows your mower to cut grass within this range and ensures its flexibility.

The blades under the mower can cut only grass that falls within this range, and shorter blades will remain uncut.

A pendulum on the mowing deck can give you a better result in the form of perfecting cutting, as a rigid structure cannot overcome the contours of the ground.

Start directional mowing

You can start from one corner of the lawn and move straight until you reach its end. However, moving in one direction instead of randomly or zig-zag is better to keep the cutting process uniform.

Then, keep moving in overlapping positions when you turn back to the next lane. An overlapping motion of a few inches to the previous lane results in perfect cutting.

You can also observe the straight lanes on the ground when it has done the work that tells about its uni-directional movement.

It does not collect grass clippings and throw them on the ground to be used as nourishment for tiny microbes and insects that can make it grow healthier.

Moreover, you can also go for the second cut in the opposite direction if required.

Apply water to your lawn

It is better to sprinkle water on the yard to provide moisture after cutting the grass to an ideal height.

Do not make it completely wet by overwatering; provide only a sufficient quantity of moisture to deal with the cutting stress. You should know that grass is a living thing and you have to take care of it.

How long does a robotic lawn mower take to cut tall grass?

The time a robotic lawn mower takes to cut grass that has reached maximum height depends on the size and shape of the yard, as a larger area takes more time.

In addition, the condition of the lawn and obstacles can also cause a delay in the cutting process. For example, large stones can damage the machine, and excess moisture requires more effort.

Moreover, the machine requires charging to operate, so the charging time of the battery is included in the overall mowing process.

You can clean a 2-acre surface within 2 to 3 hours of continuous use, but it requires frequent cleaning on alternate days to keep it in an ideal length.

So, a more extensive lawn spanning over many acres with taller grass can take many days if you use it for 4 to 5 hours a day, so you have to leave the mower in the lawn to do its task.

It can also work during the day and night when you are in the office or sleeping, as it does not require careful observation.

Accordingly, it can reach the charging port by itself and start working when it gets charged, but the charging process can be responsible for a delay in the cleaning process.

What do reviews say?

I surveyed 482 people to learn about the efficiency of robotic lawn mowers in cutting grass that had reached maximum height.

Out of 482 people, 307 people (64%) said they are good at mowing higher leaf blades that had reached more than 8 inches.

However, 139 people (29%) said these mowers are only efficient for short leaf blades that are only 4 to 5 inches tall and get failed to cut taller ones.

While the remaining 36 people (7%) said they have never tested it on tall grass as they cut it frequently and never let it grow higher than 4 inches.

It is a good device to choose when you have no time to manually deal with cutting grass as it can handle the yard very well.

“I found it a good mower that can work independently and efficiently cut down even taller grass on my lawn.”

You have to use a weed trimmer before running a robotic lawn mower into the yard to get better results for larger blades.

“It works great only for short grass because this small machine cannot deal with larger blades and get stuck within them.”

You can quickly mow small grass in a few hours, but it requires frequent cleaning if you want to keep your yard clean.

“I do not allow grass to reach a maximum height that becomes difficult to manage and takes more time to clean, so it works for me.”
