Of course, depending on their functions, the lawn mowers are divided into three groups.
The first group includes models that have only the mulching function.
Mulching involves chopping mowed grass and throwing it back. The crushed grass settles on a mowed lawn between the growing stems and is almost invisible. The mulch rots quickly and becomes a natural and organic fertilizer for the main vegetation. In addition, it contributes to the retention of moisture in the surface layers of the soil. Devices with the mulching function are very convenient to use on large areas of the lawn, because there’s no need to worry about picking grass or constantly cleaning the grass container.
The second type of lawn mowers are devices that can either collect grass immediately in a specially designed container (grass catcher) or simply throw it on an already mowed area in the form of mulch. These are basically ordinary inexpensive lawn mowers.
The third option includes 3 in 1 models, i.e. those that have all these three functions (mulching, collecting in a container, and ejecting). Sometimes the function of mulching is provided in the model, but in order to mulch, you must also buy a special blade.
