Gasoline garden trimmers (benzokosa) are actively used by gardeners and summer residents for lawn care. The small-sized unit allows you to rid the site of weeds and even small shrubs without any extra effort. The German Stihl lawn mower is considered, if not a standard, then at least one of the leaders in the segment of garden equipment.
Trim design
At the heart of any lawn mower is the engine. The Shtil company produces models with two- and four-stroke engines - respectively designed for domestic and professional use. When choosing one or another unit, it is important to take into account that two-stroke power plants require the preparation of special fuel mixtures, but four-stroke equipment is more troublesome to maintain. Next, it’s worth moving on to the main working part of the Stihl lawn mower. The description of the cutting elements can be presented as follows: a combination of steel knives and discs or a reel of fishing line fixed at the end of the rod. The variety of functional organs is due toassignment of models. The metal segments are more suitable for handling tough stalks, thick grass and shrubs, while the line excels in neatly shaping a generally manicured lawn.
Direct physical control of the tool is realized through the handle, the configuration of which is also different. Stihl designers assemble gasoline trimmers mainly with D- and T-shaped handles. Choosing the right holder model should be based on individual ergonomic requirements.
Key Features
Mowing grass on a personal plot does not require high performance, so most of the units receive a low power reserve. On average, the characteristics of the Stihl lawn mowers for this indicator vary from 1 to 3 hp. Since power equipment is now being actively converted to electric traction, for comparison with battery-powered models, it should be borne in mind that 1 hp. corresponds to 0.7 kW.
The next parameter is the bevel parameters. Like lawn mowers, trimmers can have different coverage - as a rule, either 25, 5, or 42 cm. Moreover, some modifications make it possible to adjust this value within certain limits. Structural designs can be different, and the weight varies from 3 to 10 kg on average. As for the materials of manufacture, high-strength stainless steel is the main structural element of the Stihl lawn mower. A review of the best representatives of this family will allow you to get acquainted with the technicaloperational features of this equipment.
