In addition to the different areas of application, cordless lawn trimmers with nylon trimmer line or with plastic blades and cordless motor scythes with metal blades also differ in cost. Here, we need to consider the purchase costs and the running costs separately.
Cordless lawn trimmers with nylon trimmer line are only suitable for trimming grass and lawns. This allows them to have a comparatively simple and light construction, which is ultimately also reflected in a more favourable purchase price. The same applies for lawn trimmers with a plastic blade. Here too, the area of application is limited to light mowing work. Advantages: Due to the blade drive, many trimmers manage with less power than cutters using trimmer line. The prices for good-quality devices are correspondingly low here too.
However, cordless scythes with metal blades must be more robust and powerful to be able to cut weeds and smaller roots. More powerful motors and heavier constructions provide the necessary cutting performance. This means that cordless scythes usually cost a little more than comparable cordless lawn trimmers.
The nylon trimmer line in cordless lawn trimmers is a typical wearing part, which is gradually worn out when mowing. If the trimmer line supply in the spool is slowly running out, you should get a replacement as soon as possible. The price for new spools varies depending on the length and thickness of the line.
The plastic blades in lawn trimmers also lose cutting performance over time or can be damaged on contact with hard objects. The cost of replacement blades is generally less than nylon trimmer lines.
In contrast, the metal blades in motor scythes are particularly economical. They retain their cutting performance and sharpness for a very long time and are much more robust than their plastic counterparts.
