Max. shredded material diameter

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.

Shredder speed

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.

Features

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 .

Motor type

Model of the engine installed in the grinder. The main performance data of the engine is usually indicated in the general data for the unit. However, knowing the exact name of the motor, you can find more detailed information on it — from specific data to reviews and reviews. Also, data on the engine model can be useful when searching for spare parts or consumables.

Engine size

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.

Motor power

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.

Motor power

The operating power of the chopper motor, expressed in watts. This designation is used for all electric models (see "Engine type"), but can also be used for gasoline / diesel.

The performance of the unit and its ability to cope with hard and thick branches primarily depend on the engine power. In general, the more powerful the grinder, the more advanced it is considered. However, it should be taken into account here that these moments are also highly dependent on other design features — the specifics of a particular motor, grinding system (see above), etc. Therefore, when choosing, it makes sense to pay attention first of all to the direct performance characteristics, such as the type of material being processed (see "Grinding"), its thickness (see "Maximum diameter of the material being ground"), etc. And the power itself can be useful for a general assessment of a particular model. So, shredders up to 1.5 kW inclusive belong mainly to the entry level, the middle class can carry an engine up to 2.5 kW, and higher rates are typical for professional units. Detailed recommendations on the optimal power for a particular situation can be found in special sources.

Fuel tank volume

The volume of the fuel tank provided in the design of a gasoline or diesel chopper (see "Engine type")

The larger the tank, the longer the unit will be able to operate without refueling (at the same flow rate, see above). On the other hand, the volumetric capacity has a corresponding effect on the dimensions of the grinder (and in the filled state, also on the weight).

Overload protection

Availability of protection against an overload in a design of a grinder.

Overload is a critical increase in the load on the working mechanism and, accordingly, the engine of the device. Such a situation may arise, for example, when too large or solid debris (or too many “regular” materials) enters the unit; at best, its consequences are limited to increased wear, at worst, an accident can occur. The protection system prevents such troubles by shutting down the motor (or the drive to the grinding system) in the event of an overload. Of course, you can also turn off the unit manually — however, automation is more reliable, since it constantly monitors the status of the device and reacts almost instantly.
