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.

Adjustable attachment

The cutting part of the device is fixed on a special swivel hinge with the ability to change position in one plane. By changing the angle of inclination of the blade, the operator can adjust the tool to perform a particular task. Adjustment of an inclination of a nozzle allows to increase considerably safety of work. As a rule, the saw blade (tire) has a fixed value of working positions, which are limited by the angle of inclination of the nozzle.

Battery voltage

Operating voltage of the battery in a battery-powered hedge trimmer (see above). This parameter is usually selected by the manufacturer according to the characteristics of the engine: the greater the power, the greater, the battery voltage is likely to be. In fact, voltage data may be needed only if the battery fails and it will be necessary to replace it with an equivalent one. In addition, there are formulas that allow you to roughly estimate the battery life depending on the battery voltage, its capacity and the power of the tool; they can be found in special sources.

Capacity

The capacity of the battery that comes standard with the battery-powered hedge trimmer (see above). Expressed in amp-hours, one ampere-hour means that the battery is capable of delivering 1 amp for 1 hour.

Last but not least, the battery life of the tool depends on the capacity of the battery. However, it is impossible to directly evaluate the battery life of a brush cutter by this parameter: the fact is that it depends on a number of other factors, ranging from engine power and battery operating voltage to the degree of complexity of work and contamination of the nozzle. Therefore, it makes sense to compare different models with each other in terms of battery capacity only if they do not have significant differences in other characteristics. But at the same time, brush cutters with a capacious battery a priori allow the device to work more.

Operating time

The maximum time for which the cordless hedge trimmer can work without additional charging. Note that the maximum period is indicated, which is often overestimated by the manufacturer and is calculated at idle. Under load, this parameter will be less.

Noise level

Approximate noise level produced by the hedge trimmer in normal operation. This parameter allows you to evaluate how comfortable it will be to work with the tool: the lower the noise level, the less discomfort it causes for the operator and others, and the lower the likelihood that special hearing protection will be needed during operation. At the same time, note that loud noise is an inevitable side effect of high power — it would be too expensive and difficult to make a powerful and low-noise tool. In addition, this figure is only approximate. Firstly, different manufacturers may indicate it differently: for idling, for full speed, for half power, etc. Secondly, the actual volume of work may also differ from the claimed one due to the peculiarities of a particular situation: for example, working with thick branches leads to an increase in the load on the engine, which can also affect the noise level.

Another specific point is that the decibel used to measure this indicator is a non-linear value: an increase of 1 dB corresponds to an increase of 1.26 times, 3 dB — 2 times, etc. Therefore, to assess the loudness of work, it is easiest to use comparative tables. Here is one of the simplified versions of such a table for the range in which most modern hedge trimmers work:

65 dB — loud conversation at a distance of a metre;
70 dB — loud conversation of several people at the same distance;
75 dB — shout from the same distance;
80 dB — the ringin...g of a mechanical alarm clock, a loud cry at a distance of 1 m;
85 dB — loud screams at a distance of 1 m;
90 dB — heavy truck or freight car at a distance of 7 m;
95 dB — subway car at a distance of 7 m;
100 dB — noisy industrial shop.

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.
