However, you should not only rely on the technical data. A look at the experience of other users can also give you a good insight into whether a specific battery brush cuttermeets your specific requirements.

Dimensions and weight

When working in the garden, you may spend several hours with the brush cutter in your hand. For this reason, it is important to pay attention to how heavy the tool is. As a rule of thumb, the more powerful the tool, the heavier it is.

However, the size must also be taken into account. The larger the cutting width, the easier it is to cut large areas. However, it is also more difficult to cut edges and smaller areas with large tools.

Especially with large models, it is important to pay attention to the correct weight distribution. With smaller brush cutters, the motor is usually located in the middle area of the tool. Longer tools often have their motor at the upper end to act as a counterweight to make it easier to use the cutter.

Use and charging time

The larger the area of use, the more important it is that the battery-powered brush cutter is able to function for a long time without a drop in performance. While the tank of a petrol brush cutter can be refilled immediately, charging a battery may take some time.

An empty battery should be able to be recharged within 1 to 2 hours.

A good battery-powered brush cutter should be able to run for several hours. An empty battery should be able to be charged within 1 to 2 hours. A good quality brush cutter should be able to be used for the entire running time without a drop in cutting performance.

A strong battery is also important to ensure that your tool can deliver the necessary power. A small battery is often not enough to cut through thick undergrowth. For these reasons in particular, it is worthwhile to read experience reports about the service life if you want to buy a battery brush cutter.

Handling

To be able to handle the weight, the battery brush cuttershould have an ergonomic design. The height of the pole should be adjustable. This allows people of different heights to work comfortably with it.

In addition, the handle should be made of shock-proof material. The running motor of a battery brush cutterin combination with its weight can quickly strain muscles and joints if the handle does not absorb the vibrations well enough.

In most cases, a battery brush cutteris attached to the shoulders with a strap. It is also important for these to be sturdily made and well padded. The high power of the trimmer and its weight can otherwise quickly become uncomfortable. If the belt is made of inferior material, it can be dangerous for the user in the worst case.

Range of use

When buying a battery brush cutter, you should ask yourself two questions: "What do I need the tool for?" and "Where do I use the tool?

First, the question of what for: depending on the size and nature of the area of use, different aspects become more or less important. A brush cutter used to clear brush may not be suitable for clearing grass around a tree or roadside and vice versa.

Depending on the size and nature of the area of use, different aspects become more or less important.

On the question of where: If you use your battery brush cutter for a lawn, a slightly smaller model with less power will probably suffice. However, if you need it to trim larger overgrown sections in your forest, a more powerful model with an iron blade is probably essential.

Guide: Questions you should ask yourself before buying a battery brush cutter

When buying and using a battery brush cutter, many questions often arise. Below we have selected a number of these questions and problems for you and answered them in detail.

What is the difference between a battery brush cutterand a lawn trimmer?

If you are just looking into the topic of brush cutters on the internet, you will quickly stumble across a few terms. Lawn trimmer, brush cutter, brush cutter. In addition, the terms are sometimes used as synonyms for each other. However, the various tools differ in some aspects.

In general, the various cutting tools can be distinguished by their different levels of performance, size and area of application. Generally speaking,
Lawn trimmer < battery-powered brush cutter < petrol brush cutter.

As a brush cutter usually offers more power than a lawn trimmer, it is better suited to cutting long grasses and harder undergrowth. A simple lawn trimmer would probably fail on these.

For this reason, it is often more worthwhile to buy a brush cutter if you have a larger garden or lawn. A grass trimmer, on the other hand, is great for edging smaller areas such as under a fence, along the roadside or around a tree.

What types of battery brush cutters are available?

If you decide to buy a battery brush cutter, there are two types you can choose between. Either one with a steel blade in the head or one with a cutting cord. Both models have their advantages and disadvantages, which we will explain below.

Brushcutters with blades

Brushcutters with blades

A brush cutter with a blade has a mostly metal blade with several prongs at the lower end of the tool. The motor of the tool rotates the blade, which enables effective cutting.

A battery brush cutterwith a blade head is ideal for cutting hard brush. The heavy blade allows the tool to be guided stably as the weight is on the head end of the tool. The hard, sharpened blade even manages to cut through thick brush and thin branches.

However, this model is difficult to use on vertical edges. For example, if you try to work around a tree or at the curb, the blade will potentially cut into the bark of the tree or the stone. This can damage the tree or cause sparks.

Advantages
  • Stable work
  • Cuts even hard undergrowth
  • Durable
Disadvantages
  • Higher risk of injury
  • Less suitable for working on corners
  • Becomes blunt over time
String brush cutter

String brush cutter

With a string brush cutter, a spool, usually made of nylon string, is installed in the cutting head of the device. The cord is rotated in a circle and cuts the grass or undergrowth.

Edges can be easily cut by a brush cutter with string. The nylon cuts through grass or thin undergrowth, but is not hard enough to cut into trees. This is precisely why a string model is ideal for working on tree edges, under fences or on kerbs.

The disadvantages of this model are, on the one hand, that they have difficulty cutting shrubs above a certain hardness precisely because of their material. In addition, the thread can get tangled inside the spool and must then be pulled out again by hand.

Another problem with nylon threads is environmental. Although nylon is biodegradable within a few months, its production is still anything but environmentally friendly in many places. On the other hand, nylon threads inevitably travel during use. The remains are then often left behind in the lawn.

Advantages
  • Easy to use
  • Cheap to replace
  • Allows easier work on edges
Disadvantages
  • Cannot cut bushes
  • Thread can get tangled
  • Spent threads sometimes remain in the lawn

What do I have to pay attention to in order to work safely with my device?

A battery-powered brush cutter is a device that can be dangerous if you use it carelessly because of its high power and sharp blade. For this reason, we would like to list the most important aspects for safe working.

The right safety clothing

To avoid injuries, the right protective clothing is absolutely essential.

There are many dangers when using a battery brush cutter. On the one hand, due to its own weight and the blade, but on the other hand also due to splinters, small stones and pieces of branches that can fly through the rotating blade. To avoid injuries, the right protective clothing is absolutely essential.

  1. Safety goggles; when cutting, grass, branches and small stones are thrown up. Protective goggles can prevent these small particles from getting into the eye.
  2. Hearing protection; The motor of a battery brush cutteris extremely loud due to its high power (sometimes over 100 db). For this reason, hearing protection is absolutely essential to prevent hearing damage.
  3. Cut protection suit; Even when using a brush cutter correctly, it can happen that the tool gets caught in something unexpected and is thrown uncontrollably towards the user. A cut protection suit prevents the blades of the brush cutter from causing worse damage.
  4. Safety shoes; Especially when working in tall grass, the brush cutter can come dangerously close to your feet. Safety shoes can prevent you from accidentally cutting your foot.

The correct use of the brush cutter

Even if you wear the right protective clothing, it is important to operate the machine in the right way. The harness must be adjusted so that the brushcutter is parallel to the ground. It is also important to make sure that the blade is properly attached to the cutting head.

What alternatives are there for a battery brush cutter?

Depending on the intended use, a battery brush cuttermay not be the right tool for the job. Below we have listed a number of alternatives and their areas of application.

The following alternatives can be distinguished:

Type What is it worthwhile for
Lawn trimmer Smaller than battery-powered brush cutter, allows precise work on edges, lower power allows safe work on tree edges
Petrol brush cutter Higher power than battery-powered due to petrol engine, Ideal for hard brush and forest work
Lawn mower For trimming large lawns. However, gets into trouble when the grass gets too long

What can I do if my machine stops cutting?

As with all equipment that is used a lot, battery-powered brush cutters also wear out. If the scythe can no longer provide the performance for which it is needed, this can have several causes.

The blade inside the pruner could have become dull from too much use. If this is the case, you need to sharpen it again. You can do this yourself. To do this, first remove the cutter from the brush cutter (it is best to remove the battery first to avoid injury). Then the blade can be sharpened with a grindstone or circular saw.

If the brush cutter is equipped with a string and stops cutting, it may simply be because the reel has run out. So all you have to do is disassemble the head and insert a new pulley.

However, if it is not the cutting head that is causing your machine to stop producing the expected result, it is quite possible that the built-in battery is no longer working. With most brush cutters, the battery can be easily replaced.
