Any owner of a garden plot or a private house necessarily faced, to one extent or another, with the problem of recycling vegetable waste. Especially this issue is exacerbated with the beginning of spring works and at the end of the season, in the fall. We have to devise all sorts of ways to get rid of the accumulated cut branches, dry grass and leaves, from dead shrubs and the remaining leaves, etc.
To help solve this set of problems, and even get a tangible benefit from this, a special type of garden equipment will help, namely a garden chopper. Not so long ago about such a useful unit few people heard, and today it becomes, often, an indispensable assistant gardener-gardener. True, a technique of this type is a novelty for most, and many do not even know what opportunities it has and from which side to approach it when choosing it. We will help our readers - the article about garden shredder what to choose, what to pay special attention to, what are the basic
In any farm that has a garden or a garden, a lot of different vegetable waste inevitably accumulates. Beginning with early spring, with the cleaning of the territory, pruning of trees, shrubs or grapevine, the yard or the useful area of the plot begins to be cluttered with heaps, which sometimes becomes a very difficult task to get rid of. In the summer, weeding will be added during the period of mass growth of weed, cutting of bushes, removal of parasitic shoots, collection of fruit fallen from trees, etc. In the autumn - it is not easier at all, because care of trees and bushes, cleaning of the tops from vegetable beds and fallen leaves, and much more is on the agenda again.
Typically, such heaps of waste vegetation are extremely noncompact, take up a lot of space, very difficult to load and transport, and their appearance spoil the cozy site. What to do with them?
Large branches can still be sawed for firewood. To some extent part of the problem is solved by the presence of a compost pit, but it is extremely disadvantageous to lay large fragments in it, as the pit will quickly overflow, and dense branches will decompose very long.
It is quite expensive to export such garbage mountains, as renting vehicles, loading waste, and exporting all costs a lot of money.
It would seem, the simplest way out is to burn. But here is not all so clear:
All this "baggage" of problems is solved by purchasing one garden plant - chopper( often there are foreign synonyms - garden shredder or chipper).This unit is able to quickly grind out the overall plant waste into a shallow mass, with the disposal of which no special problems will arise.
Convenient kind of heating oil - pellets
This granular fuel is produced from plant waste of various types. Under certain conditions, it is possible to manufacture equipment and master home-made pellet production with their own hands - about this in a special publication of our portal.
Thus, the advantages of such an aggregate - a great many, and it is increasingly possible to see in the "arsenal" of diligent owners.
Despite the wide variety of models of garden shredders, differing in size and operational capabilities, they are all assembled in approximately one basic scheme, somewhat reminiscent of the device of a food processor.
Garden shredders can be equipped with either an electric drive or an internal combustion engine. Each of the options has its own "pros and cons".
They usually do not differ in size and weight, so they easily move to the place of work. Their maintenance is minimized, training in operation, start-up and management does not require any special skills.
At the same time, their "attachment" to the power grid can be an inconvenience. For example, in a countryside area of a large area, a long cable will be required, which is not always convenient, and sometimes simply impossible, because of the banal lack of a connection point. There are certain limitations in the work and the weather criterion - just for reasons of electrical safety.
As a rule, they are equipped with a two-stroke gasoline engine. Such shredders can already perform more extensive work, recycle large enough plant waste, down to the trunks of small trees.
The operation of the gasoline engine will already require the owners of certain handling skills. So, for refueling it is necessary to prepare a fuel mixture, it is necessary to regularly check the state of the candles, gasoline and air filters, and carry out preventive works. However, the technology of this class does not put too complicated ICE, and all this can be quickly learned.
But in the domestic conditions, such shredders are practically not found, simply because of their high cost, large size and complexity with self-transportation throughout the site.
However, the type of drive is not always the determining factor in the question of the "professionality" of the chopper. So, you can buy a compact household model with a petrol two-stroke engine, and at the same time there are stationary or mobile installations of the pro class, equipped with a powerful three-phase electric motor.
The torque from the power drive is transmitted to the working tool - the cutting or grinding mechanism of the shredder. And it, in turn, can be arranged differently. So, three main types are divided:
Advantages of this scheme - its simplicity, low price, ease of maintenance. Well-honed knives can process foliage, grass, stems of bushes and annual plants, usually up to 20-25 mm thick. The mechanism of this type perfectly copes with freshly cut branches and branches, but when processing hard, dried up vegetable waste, blades can become blunted( even a large fruit seed, for example, from a plum or peach) can cause a problem. In some grinders, knives of a special configuration having several blades, located at an angle. The upper knife cuts the fed branches into smaller fragments, and the lower one already provides the final grinding.
For the knife-type mechanism, forced feeding of material for processing is required - it will not "tighten" the branches into itself. For this, special pushers are used.
In service such shredders are the simplest, that is, removing the knife for sharpening or replacing with a new one is usually a very simple procedure. Most household appliances have such a mechanism.
The teeth of the rotating cutter are able to "crack" sober wood of dry branches and trunks, turning them into small chips. But with freshly cut branches and shoots, this mechanism does not always manage - the fibrous structure is "chewed", but it can not completely mellow.
The cutter does not need to be in the singular - on one shaft there can be several, with a certain angular "takeoff" position of the teeth. And on the powerful installations of the professional class, there is often a two-rotor grinding mechanism, where two rows of mills rotate in the opposite direction, ensuring crushing even the hardest wood waste.
The convenience of the milling mechanism of grinding is also in the fact that it is enough for him to grab a long branch or trunk - then the gear simply drags it inside while splitting it into small pieces.
This structure of the cutting mechanism makes it possible to successfully grind both freshly cut and old, dried waste. True, garden shredders of this type are already much more expensive.
Rotating screw with sharp spiral turns perfectly copes with any type of plant waste - it all depends on the power of the plant itself.
These two concepts, rendered in a sub-title, have a direct connection. From the power drive power in the first place will depend on the functionality of the chopper as a whole.
There is no clear gradation of all the diversity of such technology, but there is a conditional division into three groups - the household, middle, semi-professional, and, finally, professional purpose devices.
To better understand the criteria of such a subdivision, it is better to present them in the form of a table:
|Category of shredders||Power and type of drive||Limiting diameter of grindable branches||"Weight category"||Application areas and features|
|Household||up to 1.5 kW, electric drive||up to 25 mm||Up to 20 kg|| Small suburban or adjacent areas, mainly with young trees. |
Short cycle of continuous operation.
As a rule - knife mechanism.
| Mid-range, |
|up to 3 kW, electric drive or two-stroke ICE||up to 40 mm||up to 40-50 kg|| Average households or suburban areas with orchard, bushes, old trees requiring regular pruning. |
Cope with any type of "green" and dried waste in the specified size range.
Are capable of a long enough non-stop operation
|Professional||from 5 to 9 kW, gasoline or diesel drive, three-phase electric motor||60-80 mm||up to 100 kg and above|| Disposal of waste in forest park facilities, industrial plants, large farms,in public services, etc. |
Designed for long cycles of work during work shifts.
Naturally, as the capacity and productivity of the garden shredder increases, so does its price. Therefore, before the purchase of equipment, it is necessary to carefully weigh the planned volume of forthcoming works, the characteristics of the waste to be recycled, the frequency of using the shredder and other parameters. It will be insulting if the purchased shredder either does not cope with the load imposed on it, or its capacity, for which a lot of money is paid, will remain simply unclaimed.
In addition, the more powerful and productive the chopper, the larger and heavier it is. From this point of view, an adequate assessment is also needed - how much will it be possible to move around the site, especially on the ground.
shredder There are a number of important details that require attention when choosing a suitable model:
are clearly visible on many models. On many models, the receiving hole can have a pronounced slit or cross-shaped shape, or be equipped with guiding ribs - these "tricks greatly facilitate the feeding for processing of loose branches.
Models of medium and professional class, in addition, can have two receiving hoppers - each for its type of waste. For example, the supplied soft waste falls on the knife grinding, and the hard branches - for crushing with a milling cutter.
In other models, removable bags can be used as receptacles on the outlet neck. By the way, on forums you can meet critical comments of users - bags sometimes break out at high speed with sharp fragments of crushed wood.
There may not be any collection at all - the exit throat is located at a certain height. Allowing to substitute, for example, a basket. It is often practiced to eject crushed waste directly into the soil of the site. In this case, the models with the ability to adjust the direction and height of the ejection will be particularly convenient.

On the features of the choice of models with petrol engines, we will not dwell here. The subtleties of the choice of garden technology with ICE - two-stroke and four-stroke schemes, start-up systems, lubrication, the procedure for preparing a fuel mixture, etc., are given enough attention in another article of this site.
Motorcycles - reliable assistants on the country side of the
On how to correctly select the petrol trimmer - the engine - read the special publication of our portal.
The variety of models of garden shredders is very high, and this sometimes even prevents you from correctly determining the optimal model. The technique of this class can not be called too cheap, therefore, money should be given only for high-quality products.
The fact is that the market has a great variety of different techniques of completely unknown manufacturers, disguised as sonorous European or Russian names. The overwhelming majority of such samples are semi-underground Chinese manufactures in the negative sense of the word( many on sale and really high-quality equipment from China).The peculiarity of shredders is that the efficiency of their work depends not only on the drive, but also on the quality of the cutting equipment. But in this matter, the manufacturer's dishonesty is often manifested - knives or cutters are made from externally beautiful and shiny steel, at first they are sharp, but literally after a few approach they are stupid, and they are not subject to qualitative sharpening.
And if you add to this the fact that the cutting equipment is not interchangeable, it is not far from the situation when the recently acquired device will stand idle for a long time simply because of its "incompetence".
So, if you buy a garden shredder, then the choice of honeycomb make in favor of proven models of well-known companies. These include Viking, AL-KO, Black & Decker, Gardena, Bosch. Very good reviews deserved the garden technique of Russian-Chinese production "Elitech" and "Zubr".Traditionally, the aggregates of the companies "Craftsman", "Makita", "MTD", "Oleo-Mac" are in high demand.
The table below shows several models that, based on the results of conducted surveys and sales analyzes, top the list of popular garden shredders:
The author of the publication expresses the hope that this information will help the interested reader to make a really correct choice of the optimal model of garden shredder.
