Head for trimmer: types and description

One of the most common devices for cutting grass is the trimmer. It is very easy to operate and maintain. That's why it became popular among the population. Its significant advantage is its low weight. Even a child can cope with such equipment.

What it is?

The trimmer consists of a cutting element, a rod, an engine and a handle with a control mechanism. It is designed for cutting grass in the garden areas, as well as to create the perfect lawn. Due to its compactness, the device performs the necessary work in places where the lawnmower can not reach. In addition to grass, the trimmer is designed for mowing branches of trees and shrubs, as well as creating flowerbeds. Such equipment is not always used for the lawn, since the length of the grass will have a different height.

Specifications

The main technical characteristics of the trimmer are:

• power;
• Weight of equipment;
• Type of power (from the network or using a battery);
• Engine layout (top or bottom);
• Type of cutting element;
• Rod type.

All this must be taken into account, to buy this or that device.

How to choose the right one?

Before buying this equipment, it is necessary to understand for what purposes it will be used. For a large area with an even lawn, it is better to buy a light model with a small capacity. If you want to improve the villa site, then you need to choose a model more powerful.

Cutting tool

For the cutting process to occur easily, it is necessary to choose the correct cutting element. In his role is often a regular trimmer line or knife. When choosing one of the species, it is worth to evaluate the type of vegetation. In accordance with these data, a cord is selected, a knife of a certain shape. An important element is the head for the trimmer. Her species we will consider below.

Trimming head trimmer

It is a special assembled coil, inside which is a cord. Its dimensions can be varied. On the inner part of the spool, a cord length of 15 meters should be wound. Its ends are pulled out for a certain distance to complete the work. When encountering a solid object, it is destroyed. The mower head for the trimmer can be of different design. It all depends on the type of device. They differ not only in construction, but also in the way they are attached. Also there is a head for the trimmer universal, which is suitable for different equipment. This was made possible by special adapters.

Kinds

The head for the trimmer is classified by the method of feeding the line:

1. Manual. In this case, the name speaks for itself, that is, the filing of the line takes place mechanically. To make the cord even longer, you must stop the trimmer and manually pull out the ends.
2. Semi-automatic. If you want to replace the cord, you need the head for the trimmer to touch the ground. At the same time, a special button is pressed and the anchor mechanism is opened. Further, the cord is elongated due to centrifugal force. The main feature is that the procedure occurs when the trimmer is on.
3. Automatic. To extend the cord, reduce the engine speed. Further, when increasing them, the line is fed automatically.

From all of the above it follows that the hand mower head for the trimmer is uncomfortable. That's why you should choose an automatic type. However, such a head for a trimmer is not popular with users, since a lot of fishing line is used during operation. Consequently, the optimal type is semi-automatic.

Classification by refueling method

The head for the trimmer can have several ways of filling the line:

1. Fast-charge. The new cord is reeled up without parsing the coil, that is, you do not need to remove it from the device. The end of the new element is caught in the coil and then wound up a certain number of times. When a specific value is reached, the cord is cut off. The head with a fishing line for a trimmer of this type is produced by Shindaiwa and Speed-Freed.
2. Demountable. Here the name speaks for itself. To replace the new cord, you need to remove the coil from the equipment, then unwind the old line and wind a new one.

Design Features

It should be noted that the cutting head for the trimmer contains special arrows. They allow you to perform rotational movements of the coil in different directions. If there was a need to wind the line in the direction of rotation of the shaft, it turns into a specific position. A large number of wound cord threatens to break down the equipment. Two arrows are contained only on imported models. Now the market has heads with one arrow.

If, after hitting the semi-automatic head, the cord is not wound, then the previous winding is not performed correctly. That is, after the head for the trimmer was installed, the user did not pull the ends of the line from the grooves. Another unpleasant moment at the bevel of grass can be the sintering of coil turns. Because of what is this happening? This happens when you meet a cord with a solid object. In this case, it abruptly slows down and, with the subsequent movement, the line begins to enter the device. Thus, it falls on the spool and sticks together. Because of this, the employee has to take a break and correct the situation. However, this can be avoided. Before installing the coil, it is necessary to treat the line with a special silicone substance.

For different trim models, a semi-automatic head is used, consisting of two parts - a body and a spool. Both elements contain springs. The second part can be executed in several variants:

• One-piece - both parts of the line are wound together;
• Two-section - each end is wound on a certain part; This species is most effective, since the line is not confused and does not cake.

There is a simple and cheap way to turn a single-section spool into a two-section spool. To do this, you need a solid plate. From it, you need to cut a circle whose diameter should be equal to the thickness of the spool. In this case, the thickness is taken near the place where the line is wound. This circle moves freely. Further, a cut is made on the ring, it is put on the spool and connected by means of glue or tape. As a result, it is possible to wind the fishing line on the required section. The head for a universal trimmer can have from two to four holes, which are located opposite each other. Out of them come the mowing ends. In addition to the presented coils, there are heads where a certain size of the line is inserted. In this case, the number of whiskers increases to twelve. Many users believe that such a device is quite convenient. However, not all people hold this opinion. They believe that in this situation the fishing lines will have to be used more. In addition, to replace it, you must stop the workflow. The head for the trimmer, whose caliber can be varied, is suitable for cutting grass, shrubs and trees. Before you buy a trimmer, you need to study the terrain, as well as the features of the equipment. So, we found out what the head for the trimmer is universal and how to properly fill it.
