You need to cut the grass at an even height so that it retains the lush green color and the texture maintains its richness.

However, you’ll notice that the grass that’s shortened using a blunt blade will have uneven tip which deteriorates whole lawn. So, if you are left with uneven height of grass, sharpen the blades.

Check The Thickness Of The Blades

During the regular use of the blades for lawn cleaning and maintenance, soil, water and chemical contact leads to erosion of steel and accumulation of debris on the surface. This prompts the user to keep it polished. During the sharpening process, the blade gets its edge back but significant loss of metal occurs on continuous sharpening. Check the thickness of blades and avoid fatal accidents such as sudden breakdown that could further harm the machine.

Here’s how you can do it!

Grass Type

There are varieties of grasses that need to be trimmed but due to their different plant structure their height should be monitored. For not chopping off the grass part that contains healthy photosynthesis cells, one has to gain the knowledge of which type of grass they are working on.

For example:

Bahia Grass- 2” – 3”
Bentgrass- 1/4” – 3/4”
Fine Fescue- 1 1/2” – 2 1/2”
Tall Fescue- 2” – 3”
St. Augustine- 2” – 4”

Grass Height

Chopping off the grass all at once is not only bad for health of the grass but also for the mower blade. That’s because the higher the impact, the larger the damages. As a golden rule, it is advised to mow 1/3rd of the grass height at one run. If you’ve wildly growing strands in your lawn then wait for 3-4 days after one run of mower and then cut the 1/3rd again. These consecutive runs will allow the grass to heal & sustain the trimming and won’t left the ground go dry.


Grasses are not always sucking good nutrients out of the soil. During summer, they protect the soil from running dry. It’s said, taller grass helps to retain moisture and water deep into the ground due to its longer roots. Therefore, your mower blades should be placed higher during the summers. However, springtime is about new saplings and sunlight must reach ground for them. Hence, lower mower height is expected.

How Often Should You Mow?

Coming to the final quest, there’s basically no science to prove how often you must wear your farmer pants and run down the field with this machine but there’s a decision you must make – what’s the height you desire. Lower the height of your grass, more you’ll have to imply your time to keep it that much. Taller grasses, lesser time you’ll need to mow.
