Attachments
—
For bushes. Nozzle designed for cutting branches of small thickness, characteristic of most shrubs. The general principle of operation of such a device is similar to clippers: there are two sets of teeth located close to each other, one of them is stationary, and the second moves back and forth at high speed during operation. As a result, each pair of movable and fixed teeth works in the manner of scissors, cutting leaves and branches that have fallen under the blades. The nozzle itself looks like a web stretched forward, on both sides of which the teeth are located; this allows you to move it in any direction during operation — to the right or left, depending on the situation. It should be noted that bush nozzles are able to cope with branches up to 2-3 cm (depending on engine power), but they are still not designed for use as full-fledged saws.
—
For grass. Attachments for cutting grass and leaves. Like bush (see above), two rows of teeth are used; and in general, a brush cutter with such a nozzle looks like an enlarged clipper, only not for hair, but for grass. At the same time, it is worth noting that it is not able to replace a full-fledged lawn mower: the cutting width most often does not exceed 20 cm, and the devices themselves are usually small battery models (see "Power") and are not structurally designed to work with large areas. Their main purpose is the decorative processing of small flo
...wer beds, as well as edges that a conventional lawn mower cannot reach.
— Saw blade. Such nozzles are very similar to the working element of a chain saw: an elongated rounded base (tyre), along the edge of which cutting teeth move during operation. They are designed to cut thick branches that ordinary bush attachments (see above) cannot handle, and are used primarily in pole cutters (see "Type").Pole length
The length of the bar usually refers to the total length of the brush attachment or saw blade (see Attachments) supplied with the hedge trimmer. The
longer the tire, the longer the cut that the tool can make at a time. In general, it is believed that a short length is typical for entry-level tools, while professional ones are equipped with larger attachments. However, here you need to take into account that the choice depends not only on the scale, but also on the specifics of the intended work: long attachments are less maneuverable and less suitable for topiary trimming of bushes. In addition, the cost of a brush cutter also largely depends on this parameter.
Tooth pitch
The distance between the individual teeth of the shrub attachment (see "Tips") supplied with the tool. The
larger the pitch of the teeth, the easier the tool will cope with thick branches, however, the quality of the work will be quite rough. Conversely, more densely spaced teeth work "cleaner" but are less suited to tough conditions and large branches.
Charging time
The time it takes to charge the brush cutter battery from 0 to 100%.
Weight
The total weight of the brush cutter. Usually indicated for a fully equipped tool, with an attachment installed and, in the case of a petrol engine, a full tank of fuel; however, there may be exceptions. Usually, the relevant data is indicated in the official documentation.
This parameter is important, first of all, taking into account the fact that the tool during work will have to be kept on weight most of the time. Accordingly, the lighter the brush cutter, the longer you can work with it without interruption, the less often you have to rest. On the other hand, a large weight also has its advantages: a heavy tool is more stable and does not “tear out of hand” as much under high loads on the nozzle.
