After cutting the lawn grass, there may be a need to better arrange the edges and their contours. The arrangement and cutting of the edges are carried out with tools called "trimmer". The term includes both manual and mechanical tools. The difference between the two types of trimmer is not only in the design, but also in the operating mode: the manual ones use only the operator's thrust, while the mechanical ones are operated by a battery-powered, electrically or gasoline-powered motor. In this section we will talk about different types of trimmers, their characteristics and how they work. Meanwhile, in this presentation page, we want to mention some of the main peculiarities related to the edge trimmers trimmer they are manual or mechanical tools that serve to trace the contours of the flower beds. The planting of a flowerbed in turn requires the cutting and arrangement of the lawn edges. Furthermore, when cutting the grass, the edges of the lawn remain uneven and almost uncultivated. In these areas it is impossible to intervene with the lawn mower, this is why we use the trimmer. The latter, as already mentioned, can be manual or mechanical. THE trimmer manuals are the most used in small gardens and small lawns. These tools have the classic shape of a shovel or spade, with a flat or rounded half-moon head and telescopic handle (extendable). The handle of the manual trimmer can be mounted and removed on the device at any time. The cutting head, usually in the shape of a blade, has straight and very sharp steel blades, so as to guarantee a precision cut. To resist corrosion, the steel blade is also coated with a thermosetting material. Modern manual edge trimmers are guaranteed for twenty-five years. For larger surfaces exceeding one thousand square meters, it is advisable to use mechanical trimmers. In the market you can also find integrated tools that include lawn mowers, edge trimmers and brushcutters. Replacing the cutting head, these tools are transformed from time to time into the desired device. The mechanical and integrated trimmers are generally electric, battery-powered and motor-driven. The same operating mode also for simple mechanical trimmers, which can be easily purchased at large retailers. The mechanical trimmers without other integrated functions are usually composed of a telescopic rod that can be extended at will, an ergonomic handle and a blade or nylon line head. The most precise cuts are made with the wire, the only one capable of delineating the contours of the lawn in the best way. The edge trimmers, both manual and mechanical, are very light and practical tools to use. The electric ones also include the socket with wire to be attached to the power cable. These tools can now also cover areas of a thousand square meters. The wire of the electric cable could however create some discomfort in the movements. Even more practical are the battery edge trimmers, without a power cord. These allow you to move easily from one corner of the lawn to the other. The only limit: battery recharge times. To use these tools continuously, it is advisable to charge the battery a few days before use. Equally light and easy to handle are the blend trimmers, that is fuel fed. These tools are usually more powerful than electric or battery-powered and have two 1.6mm thick nylon wires. The thickness of the wire determines the cutting precision and the best shape of the edges. Electric string trimmers can always have two wires, but their thickness is smaller, around 1.2 millimeters. Cordless edge trimmers are instead equipped with a single nylon thread, but with a thickness of 1.5 mm. The choice between a model and the other will therefore also depend on the shape you want to give to the edges. The edge-trimmers can be cleaned with a dry or slightly damp cloth. Do not use solvents or abrasive materials that can scratch the surface of the materials. Edge trimmers are always cleaned after use. Sometimes it is advisable to clean them even earlier. Always before use, check the condition of the blade or wire, in order to replace them as needed. After use, the edge cutter should be stored in a dry and safe place. Non-integrated manual or mechanical edge trimmers have fairly affordable costs of between 19 and 30 euros. More expensive integrated ones, which also work as lawnmowers and brushcutters. If products for professional use, the integrated mechanical trimmers can cost as much as five hundred euros. The market also offers more and more accessible offers and we do not believe it is appropriate to spend large sums only to outline the edges of the lawn. Professional non-integrated string trimmers, both battery-powered, electric and motor-driven, can be purchased at prices between seventy and one hundred and twenty euros.
