Trimmer blade width
The width (diameter) of the trimmer knife characterizes the size of the paddle knife (or saw blade). Such a nozzle has a smaller capture width than a fishing line, however, it allows you to mow more dense thickets, including shrubs.
Line diameter
The diameter of the fishing line supplied with the trimmer (more precisely, with a reel attachment, see "Tips").
In modern models, this parameter can be from 1 to 4 mm. At the same time, a thicker fishing line handles better with dense thickets, but it works rougher, the treated lawn is not particularly even, and for the effective operation of such a nozzle, a fairly powerful engine is needed. On the other hand, a fine line provides a clean and neat cut, but is not suitable for heavy vegetation and large stems. Thus, thick fishing line is usually equipped with powerful units designed for "launched" lawns with an abundance of thick stems. Thin, on the other hand, is found mainly in low-power electric trimmers with a lower engine location, designed for neat lawns with regularly cut grass.
We also recall that many trimmers have the ability to replace the standard reel with another one that differs in line thickness.
Motor power
Lawnmower engine power expressed in watts. This designation is used absolutely for all electric models (see "Engine type"), and it is also often found in gasoline and diesel units along with horsepower (these units are clearly related, 1 hp is about 735 watts).
In general, the more powerful the engine, the more performant the mower and the better it will cope with heavy work such as cutting thick grass, bushes, etc. On the other hand, high power has a corresponding effect on fuel / electricity consumption, as well as the weight and price of the engine. In addition, note that the power requirements depend on the type of mower itself and its engine (see above for both). For example, for most
robots, the power
does not exceed 500 W — more, taking into account specialization, is not required, besides, otherwise the devices would turn out to be too bulky and heavy. Trimmers and lawn mowers of similar power are only electric, and the power limit for power tools is
2500 – 3000 W when powered from the mains and
1500 – 2000 W for battery models. But in gasoline tools, the minimum power is about
500 – 1000 W for trimmers and
1000 – 1500 W for mowers; the maximum value can exceed
4 kW.
