Principle of operation
The principle of the shredder's work can be correlated with the functioning of a giant meat grinder. A variety of wastes are laid inside, which are then grinded with a grinder. The condition of the final product can vary from full-fledged sawdust to small pieces. The chopper is a housing containing a motor inside, which is responsible for the operation itself, and a chopping system. A funnel is placed at the top, into which garbage is placed. Usually, its diameter is directly related to the purpose of the device: wider for grass, and narrower for branches.
Recycled material exits through a hole at the bottom of the shredder from a separate hole. It can end up in either a plastic container or soft cloth chalk. There is also an option when the garbage simply spills out, and the owner himself must decide the issue of loading it. It is worth noting that the plastic container is much more convenient to use, but it takes up enough space for storage, and it adds to the weight of the shredder itself. As for the bag, it is quite compact, but not so easy to use.
Varieties
Depending on the engine used, choose an electric and gasoline shredder. The electric engine guarantees less weight of the unit, no exhaust and relatively quiet operation. Unfortunately, the use of such a shredder can become difficult due to the presence of a short cord or the absence of its connection points in nearby access. Of course, the issue is solved by purchasing an extension cord and carrying, but this is an extra expense and only a satisfactory comfort from use. The power of electrical units, as a rule, ranges from 2 to 5 kilowatts, and their cost fluctuates within the boundaries of the middle segment.
The petrol engine makes it easy to transport the shredder wherever you go. However, the design itself is very massive, since the engine is also impressive in size. The additional weight is added by the fuel used. Such designs are quite powerful and costly. Thus, an electric motor is more suitable for a small area, and a gasoline one for large areas with a large amount of organic waste. By the way, there is also the possibility of connecting the shredder to a garden walk-behind tractor or other equipment for performing agricultural work. Such a system is convenient for use in horticultural farms.
Garden shredders are also subdivided depending on the cutting units. They can be equipped with knives, two or more. Two cutting points speak of the simplest model that can cope with grass and branches, the diameter of which does not exceed 2.5 cm. Such knives are located in a horizontal plane. There are also models with 4 or 6 knives, which are located both vertically and horizontally.
The next type of crusher is equipped with a worm-type crusher. In this case, the cutting blade is a kind of screw with a small number of turns, placed vertically. Such a device handles branches with a diameter of approximately 4 centimeters. In the case of grass, the situation is not so straightforward: the unit processes it, but often the grasses stick or wrap around the screw, and therefore it has to be cleaned. Crushers with a worm crusher are considered universal.
There are also devices equipped with a cutting unit in the form of a cylinder with a large number of knives. They are mainly produced by Bosch. The cutting part can be disassembled with both vegetation and branches. Winding grass on a screw is extremely rare or if the knives are dull. This type of shredder is versatile. Finally, some devices have a cutting shaft - the most powerful crusher. The unit copes even with thick branches, but only if their length ranges from 5 to 8 centimeters. This device is not recommended for work with grass.
Purpose and benefits
The main function that an electric or gasoline garden shredder is designed to perform is to dispose of plant waste by shredding it.
The motor drives special cutters that turn branches, dry grass, fallen leaves into small crumbs.
This is important: compared to burning garden waste, using a shredder allows you to get high-quality fertilizers from it.
In addition, a garden shredder (aka chipper or shredder) has the following advantages:
- compact dimensions with high performance;
- high mobility;
- low power consumption.

When choosing a household garden shredder, you don't have to chase the maximum power. Excessiveness of this indicator can lead to unjustified expenses. After all, the more powerful the shredder, the higher its cost.
For a small suburban area, an inexpensive electric chipper with a compact size is quite suitable
In addition, you need to pay attention to the following characteristics:
- engine's type;
- the degree of fractional grinding (sawdust, shavings or small chips);
- the presence of wheels;
- body material (more durable metal or less resistant plastic);
- operational safety A very important nuance is the availability of a spare set of cutting elements. Even the most durable metal will sooner or later become dull and fail. Having a spare cutting unit is a definite plus!

Features of operation
Compared to gasoline counterparts, electric shredders are more maneuverable, but they do an excellent job of recycling garden waste. During the use of shredders, no special skills are required, but before starting work, it is necessary to study the instructions for the device.
The only moment limiting the work will be the need for a power source, as a result of which the extension cord will have to be pulled across the site. This feature requires compliance with personal safety measures due to the operation of the device from electricity, therefore, it is better not to operate the shredder in wet weather.
In the next video, a specialist will tell you how electric garden shredders work, how they need to be looked after, and by what criteria to choose.
a brief description of
First you need to figure out what a garden shredder is. The tool can be compared to a large meat grinder, which grinds branches, cones, bark, roots and other waste instead of meat. The grinding level can be adjusted to produce sawdust or small pieces. Shredders are gasoline and electric. Knife system - disc or milling.
The disc includes several steel knives. Ideal for processing green stems, thin dry twigs, grass, leaves and other "soft" waste. The milling system is a monolithic gear that automatically absorbs what you want to grind. The powerful mechanism easily grinds thick branches, but the grass often gets stuck in it.

The range of these devices includes various modifications of garden equipment based on this there is a certain classification of shredders.
By body type
Devices are made of lightweight metal, polymers, or a composition consisting of different raw materials. As a rule, the first type of unit will be distinguished by its mass, which will significantly complicate its transportation. When purchasing such garden shredders, you should give preference to products with wide wheels to make the device easier to move around the site. Other types of shredders have a lightweight body, so there are no problems with their transportation during operation.
engine's type
The processing speed of the loaded garbage directly depends on the power of the unit. There are devices on sale with a performance of 1.5, 3, 6-9 watts.Based on this parameter, the diameter of the branches that the device can grind varies - 25, 40 and 60-100 mm. And also the weight of the unit depends on the performance of the motor. In the first case, the devices will weigh from 10 to 20 kilograms, medium-sized shredders, as a rule, weigh about 25-30 kilograms, large shredders designed for processing waste of serious volumes can weigh about 100 kilograms.
Grinding mechanism type
Electric garden shredder manufacturers offer equipment equipped with circular blades or a milling cutter system. The first category of devices is recommended for the disposal of thin branches, grass and green mass of crops, since dense parts of plants can lead to premature blunting of the tool. The milling mechanism is an analogue of a household kitchen meat grinder. This version of the shredder is more productive, usually equipment of this kind turns branches into chips with a cut thickness of up to 10 centimeters, including dead wood.
Device and technical characteristics
The functioning of a garden electric shredder occurs in the course of the well-functioning work of several mechanisms. The equipment in the housing contains a motor and a cutting system, into which the collected debris enters through a special opening in the device. Further, chips and recycled leaves and grass residues go into a bag located at the bottom of the shredder, and garden debris can simply spill out after crushing on the ground. The funnel itself has the shape of a cone with an angle of inclination towards the cutting mechanism, which greatly facilitates the process of getting branches and other parts of plants inside.
Depending on the modification, garden shredders may contain several holes for loading garbage, which will differ in the dimensions of the branches. For safe operation, shredder manufacturers equip their equipment with an anti-start-up system. Thanks to this function, the shredder will not be able to spontaneously start working after power surges or other unforeseen factors.
There are professional shredders, which are additionally equipped with a set of knives installed in front of the main cutting mechanism. Such modifications are distinguished by their productivity and long service life with minimal breakdowns. Depending on the model, the shredders can be equipped with a speed control system. In addition, modern garden electrical devices are equipped with a pusher, which will provide more comfortable transportation of the device across the territory.
