Measure the lawnmower cutting height in 4 easy steps.
● Step 1: Identify the grass type in your yard
Before you start mowing, a necessary prerequisite is to inspect your lawn. By checking, we mean knowing what grass is in your yard. This step is crucial in determining the best cutting height for your lawnmower.
Grasses could be categorized into numerous classes depending on the climate, location, and soil type. Fine and tall fescue, Kentucky bluegrass, and Perennial ryegrass are cool-season grasses. They should be cut to a height of 0.75 inches to 4 inches.
Bahiagrass, centipede grass, and Bermuda grasses are examples of warm-season grasses. The optimum recommended height for them ranges from 0.5 inches to 3 inches.
● Step 2: Make a few measurements and adjust accordingly
For the second step, it is necessary to have a ruler or a measuring tape. With a ruler’s help, measure where the mower’s housing hits the ruler. Always remember that the housing is where lawnmower blades would not cut grass.
We will adjust the mower’s height in the coming steps to cut the grass at the ideal height. Once you have found it, note it so that you can use it in the future. The height adjustment may vary from brand and model and the lawnmower type.
In your case, it is recommended that you check the user manual to see how it needs to be done. For smaller lawnmowers, the basic procedure to adjust the lawnmower’s height is to pull the adjustment lever near the wheel. Bigger sitting lawnmowers usually have a big leaver that sets the height.
In my 20 years of experience, I’ve seen firsthand how crucial it is to set the cutting height on a lawnmower correctly. Cutting too short can stress the grass and make it more susceptible to pests and diseases. It’s a simple step that can make a significant difference in the health of your lawn.
● Step 3: Do some test mowing
Once you have followed the steps mentioned above, it is time to put your adjustments to the test. Choose a small patch for a test, and start mowing it with your just-made adjustments.
● Step 4: Check the Height, and adjust if needed
Once you have mowed the test patch, measure the height of the cut grass with a ruler. Compare it with some uncut grass. Inspect whether the cut grass has the correct height, as planned. If the height is not what you anticipated, readjust the height and try again.
Tips for Cutting the Grass at the Right Height.
● Tip 1: Follow the one-third rule
The one-third rule is a general rule of thumb that states that you should not cut more than 1/3 of the height. This helps to keep the grass healthy and robust. The grass’s ideal height depends upon the type of grass in your lawn. You can let it grow a third more than this perfect height if you know it.
After mowing, you are left with the ideal recommended height. You can continue letting it grow a third more and then cutting it to the perfect height. As it is difficult to go out repeatedly and measure the height of the grass, there is a tip that would make things easier for you.
Draw a line across one of the lawnmower’s tires that stands one-third above the ideal height. Draw an arrow to show the up or down direction. When you think mowing is needed, bring your mower out and see where the grass stands about the line you made.
● Tip 2: Cut to the correct height
When you want to start mowing, you should follow a good process. Aimlessly starting to mow your lawn, instead of adorning the yard, will make it look disheveled.
Before mowing, you should ensure the height is neither too high nor too low. A low height could stress the grass, while a higher height does not look pleasant.
● Tip 3: Avoid scheduling the mowing sessions
Although scheduling your garden tasks is an excellent method to maximize your time, following a weekly schedule is not recommended for lawnmowing. It is better to start mowing when needed after inspecting your lawn and checking the grass’s height.
Start mowing if the height exceeds a third of its ideal height (depending on the grass type). Scheduling doesn’t work in mowing because the grass height of the lawn greatly depends on the weather and other conditions.
The grass’s growth rate varies a lot. So, instead of following a weekly mowing schedule, inspecting the height of grass regularly is recommended.
Over the years, I’ve learned that factors such as the type of grass, the season, and the lawn’s health should all be considered when determining the optimal cutting height. For instance, cool-season grasses often require a higher setting than warm-season varieties. It’s not a one-size-fits-all approach.
● Tip 4: Sharpen the blades
Make sure that your lawnmower blades are always sharp before you start mowing. Sharp knives are necessary for a clean and fine cut to your needed height.
If the blades are dull or blunt, no matter how well you have adjusted the lawnmower’s cutting height, there will always be unfine cuts and stressing of the grass.
Please make sure that you handle the blades with care and caution when you are going to sharpen them. Using safety gloves in this regard is highly recommended.
● Tip 5: Mow at the right time
Choosing the time to mow your lawn is also crucial if you are looking for a fine-cut result. Most people prefer to perform mowing during the daytime. However, this is not the best time for your grass. When the grass is dry, mowing your lawn in the early evening is better.
If you use your lawnmower on wet grass, the soil’s moisture and the damp grass will make mowing much more difficult. The grass will stick everywhere and clog your mower.
-Why Morning Time is Not Ideal for Mowing
Morning time is never recommended, except when the grass is dried. Wait for the due to leave. Another reason wowing during the daytime is sometimes not recommended is when it is rot. Excess heat adds stress to the grass.
Thus, early evening is highly recommended as the grass is moisture-free at that time, and there will be no or less stress on the grass due to heat. The grass can then further recover overnight.
● Tip 6: Change Things up
It is recommended not to follow the same pattern whenever mowing. This may cause the soil to get more compact, resulting in ruts, stunted growth, and grass development. Weeds prefer to grow in compacted soil. Try to change the pattern and direction you mow between the sessions.
One common mistake I’ve seen people make when setting the cutting height is setting it too low. This can damage the grass and lead to a less healthy lawn. It’s better to err on the side of cutting too high than too low.

• Risks of Cutting the Height of Grass Too Short
For instance, during winter, 35-40mm might be ideal. Be careful not to cut the grass too short, as it can deprive it of vital nutrients and make it more susceptible to weeds and diseases. When mowing a lawn, you must check the gap from the ground to the bottom of your lawnmower’s deck.
This is because the gap from the ground to the lawnmower’s grass blade determines the cutting height. So, how do you measure this gap? You can use a ruler or a tape measure to check the distance from the ground to the bottom of the lawnmower’s deck.
Also, remember to clean the underside of your lawnmower after each use to prevent the buildup of grass clippings and debris. This will ensure a smooth and even cut each time you mow your lawn.
