What is the purpose of adjusting the height of cut on a mower?

Adjusting the height of cut on a mower is fundamentally important for promoting healthy grass growth. Different grass species have specific height requirements that support their health and vigor. Cutting grass too short can stress the plants, leading to issues such as scalping, reduced photosynthesis, and increased susceptibility to pests and diseases. Conversely, if grass is maintained at the proper height, it can establish a stronger root system, retain moisture more effectively, and compete better against weeds.

Maintaining an optimal height encourages thicker growth and healthier lawns overall. Additionally, this practice can lead to improved resilience during periods of drought or stress. Some grass types thrive when kept a bit longer, which is why adjusting the mower height is crucial for the overall management of lawn health. While aesthetic appeal, speed of mowing, and maintenance frequency may have some relevance, they do not directly correlate with the primary biological needs of the grass in the same way promoting healthy growth does.
