Choosing The Right Cutting Height
Choosing the right cutting height depends on several key factors. Different grass typesneed different heights to stay healthy. For example, cool-season grasseslike Kentucky bluegrass grow best at 2.5 to 4 inches. Warm-season grasses such as Bermuda grass do well at 1 to 2 inches.
Seasonal changes also affect cutting height. During warm months, grass grows faster and may need a shorter cut. In cooler seasons, raise the blade to protect grass from cold stress. Cutting too low can damage roots and cause brown patches.

The height adjustment mechanism is often found near each wheel or under the mower deck. Look for a lever, knob, or dial that controls the cutting height.

Make small changes to the height settings for better results. Adjust in small steps to avoid cutting too low or too high. Test again after each change to find the best height. Keep track of each adjustment for consistency.
Maintain the same cutting height across the entire lawn. This keeps the grass healthy and looking neat. Regularly check the mower settings to avoid uneven cuts. Clean the mower deck to prevent clogs and uneven cutting.
