    frequently asked Questions

    What are the advantages and disadvantages of a lawn trimmer with a blade?

    A grass trimmer that is equipped with movable metal or plastic blades is associated with certain advantages and disadvantages due to the specific cutting tool. These pros and cons apply when compared to classic line spool lawn trimmers.

    The advantage is that a grass trimmer with a knife can also shorten thicker undergrowth - the gardener with a line trimmer usually fails.

    This advantage is offset by two disadvantages: the knives can break easily and replacement knives are relatively expensive. In addition, the knives are not suitable if you want to cut or remove grass on walls or house walls. The cutting tools quickly leave behind damage such as scratches on the surfaces or break themselves.

    tips

    With some lawn trimmers, you have the option of changing the cutting systems with the appropriate attachments as needed and at will - i.e. knife and line. It is interesting that when using knives, lower speeds have to be reached than when using a line, so you can also use a grass trimmer with less power if you prefer the knife as a cutting tool.
