Comparison HECHT 6173 vs HECHT 624 BOX

The type of engine that powers the grinder.

— Electric (mains). The electric motor, usually, is powered by a conventional 230 V household network. Electric shredders are less noisy than gasoline and diesel ones, they have less weight and dimensions and do not produce exhaust gases, which allows them to be used both outside and indoors . In addition, the engines themselves are cheaper and easier to operate — electricity is inexpensive, you do not need to buy additional consumables, and maintenance, in fact, comes down to observing the simplest rules to prevent overload. Electrical units depend on sockets, and their freedom of movement is limited by the length of the mains wire; but, given the specifics of the application, in most cases these points are not critical. But one of the key disadvantages of this option can be called a relatively low power, which makes it difficult to create high-performance units for working with solid waste.

— Petrol. Gasoline internal combustion engine. Such motors are capable of developing more power than electric ones, while they can work independently of sockets (electricity is required only for starting, and even then in most cases a battery or a starter is used to scroll the shaft manually). In addition, they are less sensitive to high humidity conditions. On the other hand, gasoline engines are heavier, more expensive..., more difficult to maintain, they require the purchase of fuel and oil, and the exhaust gases generated during operation require such units to be used only outdoors or in rooms with good ventilation. In light of all this, this option has become widespread primarily in high-performance professional equipment.

— Diesel. A type of internal combustion engine that uses diesel fuel. According to the main advantages and disadvantages, they are similar to the gasoline ones described above, but they also have features. So, diesel fuel is cheaper and more economical, and the torque (see below) for such engines is higher; on the other hand, they themselves are more expensive, and more difficult to operate. Therefore, such engines are typical for the most powerful modern shredders.

The standard network voltage for which the shredder with an electric motor is designed. This parameter can also be called “Network type”, because The two main options differ not only in voltage:

- 230 V. Ordinary household networks, available almost everywhere where there is electricity. Most devices with such power can be connected to a regular outlet, although the most powerful models may require connection directly to the panel. However, units with similar power are mainly of the industrial class, and in them manufacturers prefer to use three-phase power supply at 400 V.

- 400 V. Three-phase networks used primarily to power heavy industrial equipment. At home, it is not always possible to connect to such networks, but in workshops, sawmills, etc., as a rule, there are no problems with it. In light of this, such power is used mainly in high-power shredders, for which 230 V networks are poorly suited. So if you are going to use the chopper often, in large quantities and/or simultaneously with other “gluttonous” power tools, and the place where it is used has a 400 V connection, you should pay attention to three-phase models.

The largest thickness of debris that the shredder can handle normally. This parameter will allow you to evaluate how a particular device is suitable for a particular situation.

Note that the maximum diameter of the crushed material is important for models that allow working with branches (see "Chipping"). But in specialized aggregates for leaves, it is usually not indicated at all: the thickness of the garbage processed in such grinders is, by definition, small, and creating a design that works normally with any “soft” materials is usually not a problem.

The speed of rotation of the cutting tool of the chopper (see "Crushing system"). Variable speed models (see below) usually have a maximum RPM value.

In general, the general pattern is as follows: with equal engine power, the higher the speed, the lower the torque (see below), and vice versa. In addition, high speed improves performance (see "Bandwidth"). At the same time, this parameter in most cases is more of a reference value than a practically significant one: manufacturers select the rotation speed in such a way that it provides the claimed throughput and at the same time maintains the torque at a sufficient level for efficient processing of materials that were originally calculated design. Therefore, in some models, revolutions may not be indicated at all, and when choosing, it is worth focus on moments that are closer to practice.

The capacity of the garbage collector provided in the design or delivery set of the grinder.

The larger the container, the more recycled material the collector can hold and the less often it will have to be emptied. On the other hand, it is not always convenient to carry a large amount of material, and a large container takes up a lot of space — and if for soft bags (see "Type of collection") the latter is relevant only when fully loaded, then rigid containers are bulky by definition. Therefore, when choosing, you should proceed from the optimal compromise between capacity and convenience.

The presence in the design of the grinder pointer, allowing you to monitor the degree of fullness of the garbage bin.

This function in our catalog is indicated for all models, the design of which somehow provides the ability to determine the level of filling of the collection without opening it. The simplest "indicator" options are narrow slots in the top of the container (through which the user can see that the contents have risen almost to the level of the edges) or translucent wall material. There are more advanced options — for example, a sensor with a light alarm. However, anyway, the indicator makes it easier to keep track of the amount of content in the collection, reducing the risk of overflow and related troubles. It is found only in models with rigid containers (see "Type of collector") — in soft bags, you can monitor the fullness without any indicator, and in the absence of a standard collector, this feature depends on the container selected by the user, and not on the capabilities of the chopper.

— Auto feed. Autofeed refers to all systems that somehow ensure the "pulling" of debris into the working mechanism of the unit. Roller chopping systems (see above) by definition have this feature; in other types of shredders, additional mechanisms may be provided specifically for automatic feeding.

— Pusher. The presence of a pusher in the design or delivery set of the unit. The pusher is a device that allows you to manually push the garbage to the working mechanism of the grinder; such devices are specially adapted to the shape and design of the receiving chamber, therefore, when used, they are more efficient and at the same time safer than various improvised means. The pusher can be useful both in the absence of automatic feed and in its presence (see above): it happens that debris gets stuck “on the way” to the tightening mechanism, which requires additional measures from the operator.

— Dual chamber receiver. The presence in the design of the chopper of the receiver, which has two separate chambers. Each of these chambers is designed for its own type of garbage; at the same time, the chopper itself can be both universal and specialized, for branches (see "Chopping"). In the first case, different chambers are designed for different types of debris, in the second — for branches of different thicknesses. Anyway, the dual-chamber receiver simplifies the wo...rk with the universal unit — it reduces the risk of confusing modes for different materials.

— Funnel for foliage. The presence of a special funnel for collecting foliage in the chopper design. Such a funnel usually has the form of a characteristic wide bell, mounted on a swivel mount and laid on the ground during use. In such a socket, as in a scoop, you can sweep the leaves collected with a rake or broom — it's easier and faster than loading them into the chopper with your hands.

— Reverse system. The presence of a reverse function in the chopper design. This function allows you to run the working nozzle in the opposite direction, and its use may vary depending on the chopper model. So, in models with roller shredding systems (see above), the reverse allows you to “spit out” a branch that is too thick or hard and release the jammed mechanism, and in some universal devices (see “Chipping”), by switching the direction, you can choose between modes for different types of debris .

The working volume of the internal combustion engine (gasoline or diesel, see "Engine type") provided in the design of the grinder. Larger engines of the same type (see above) are usually more powerful, but they also consume more fuel. At the same time, it should be noted that in fact it is more convenient to choose a grinder according to the thickness of the processed material, productivity (see above) and other characteristics that directly affect the efficiency of work; The volume of the engine is a secondary parameter, although it allows to some extent to assess the overall level of the unit.

The operating power of the chopper engine in horsepower. This unit of measurement is traditionally used for gasoline and diesel models (see "Engine type"), but among them it is gradually being replaced by watts. For details on the value of power in general, see paragraph "Engine Power" below; here we note that 1 hp. approximately corresponds to 735 watts.
