How to make a garden branch shredder with your own hands. Do-it-yourself garden shredder Do-it-yourself garden shredder

Specifics gardening work in many cases it is associated with the disposal of green mass - branches, plant stems, grass and leaves. Simply destroying waste is irrational, since it can be used to make high-quality fertilizer or use it to heat a furnace. To place such waste in compost pits, it is necessary to bring the mass into the most compact state so that the process of humus maturation occurs faster and with better quality. Shredding branches fruit trees, stems and leaves of plants by hand - a long and labor-intensive procedure. Every gardener who has at least once encountered this problem has thought about the possibilities of mechanizing the process.

There are devices specialized in performing this task, which are called shredders (shredders, chippers). They are quite effective; they allow you to quickly and easily turn a mountain of branches or grass stems into a crushed homogeneous mass, which is compactly stored in compost pits. The only problem is the high cost of such devices. Considering that the need for them arises a couple of times throughout the year, it is not advisable to incur significant expenses. The way out is obvious - you need to make a branch chopper with your own hands. This solution to the problem will require some expenditure of money and labor, but as a result, the shredder will cost much less and will allow you to perform exactly those operations that the owner needs most.

Main components of the chopper

The shredder design consists of several elements:

Grinding mechanism;
Bunker;
Drive unit;
Frame with casing (housing).

Some samples of shredders have additional components:

Mechanism for promoting material;
Sieve for primary sorting of crushed mass;
Receiving hopper for crushed waste.

The main design elements are the grinding mechanism and the drive. They are the ones who perform the task, and the remaining nodes serve to increase efficiency or perform additional functions. The task performed by the drive is simple and monotonous - it ensures rotation of the working shaft. The functions that the chopper performs are somewhat more complex and depend on its design. Let's take a closer look at them:

Grinding mechanism

This unit destroys the green mass using a cutting tool mounted on a rotating shaft. There are several factory design options for grinding mechanisms:

Knife disc. Reminds the principle of operation of a vegetable cutter in a food processor. The knives are installed on a flat disk in the direction from the center to the edges of the disk; the crushed material is fed at an angle of about 30° to the surface. Designed for processing relatively thin branches and stems with a diameter of up to 2 cm.
The disc blade unit is capable of chopping grass and branches up to 2 cm thick
Milling design. The cutting body is a knife shaft from an electric planer, a set of cutters or circular saws mounted on a common shaft and separated by washers. There is another type of design of this type, consisting of two identical knife shafts rotating synchronously. The shafts are adjusted so that the knives meet at one point on the front surface of rotation, which helps push the material into the machine. The design is capable of processing material up to 8 cm in diameter, but it is not recommended to work with damp branches or tree trunks, since the chips from them are elastic and quickly clog the shredder passages.
The milling design allows you to process branches up to 8 cm thick, but the material used must be dry
Milling-turbine knife design. It is a kind of knife shaft, but has a cone-shaped shape. The knives are mounted on two hoops located at the edges of the cutting surface, which facilitates the manufacture of the working element and reduces metal consumption. The installation is capable of working with dry or wet material, different sizes or hardness - depending on the size of the cutting organ.
The milling-turbine design allows you to cope with branches of almost any diameter

For self-made most convenient:

Double-roll structures consisting of jointer-type working rollers with 4 knives each.
Disc design.
A package of circular saws (as an option, of wood cutters installed in the same way - on a common shaft).

The choice of one option or another is made based on one’s own capabilities and preferences. In addition, an important role is played by the equipment and machines that allow the manufacture and assembly of a certain version of the cutting element. If you do not have your own machines, necessary details you should order it from a turner, which will cost some money, but the result will be quite professionally done.

Engine type and power

Electric or gasoline (diesel) engines are used to rotate the working shaft. The choice of drive is determined by its availability, power level, and site capabilities. For an electric motor to operate, you must have a connection to the network (and if the motor is three-phase, then the situation becomes somewhat more complicated), while gasoline engines are able to operate more autonomously. There is another advantage of gasoline engines - they allow you to adjust the speed of rotation of the working shaft by changing the fuel supply, whereas electrical devices operate in a single speed mode. In addition, the power of gasoline devices is usually much higher, although there are also electric motors with high power. To create a universal installation capable of working with material of different sizes and strengths, it is recommended to use a motor capable of developing a power of about 4 kW. This value was determined experimentally and makes it possible to process almost any type of material at home.

How to make a garden wood chipper

The process of creating a shredder takes place in stages and consists of the following steps:

Selecting the type of working body, creating a working drawing.
Order parts from specialists. If it is possible to carry out machine work, this item is automatically canceled.
Collection necessary materials and tools.
Manufacturing of parts, assembly and testing of the device.

Creating a working drawing is necessary for a more detailed understanding of the dimensions, connection methods and other parameters of nodes and structural elements. Moreover, some parts will have to be ordered from a turner, which in any case will require a well-executed drawing.

The first step is to select the type of cutting tool. It is determined by the capabilities of the owner, the nature of the upcoming actions, the composition and parameters of the material, the volume and duration of the work. It is necessary to take into account the complexity of replacing, adjusting and sharpening the cutting tool, its durability, and grinding ability different types green mass. In addition, you must be able to order or manufacture one or another type of working unit yourself. The most effective design is considered to be one with two knife shafts. But to make it you will need two absolutely identical shafts connected to each other gear transmission, ensuring synchronous rotation.

The unit is difficult not only to manufacture, but also to adjust the knives.

They must be periodically sharpened and installed on the shaft, which is a rather difficult task.

A simpler design option is a flat blade disc.

The main advantage of this option is the ability to dispense with the manufacture of a drive shaft by installing the disk directly on the electric motor shaft. The disk does not require a lot of space for landing, so you only need to make a disk and a protective casing with a guide screen to organize the ejection of chips.

The cutting body, which is a set of circular saws or flat wood cutters, is quite simple to make from the drive shaft for a circular saw.

You can simply convert an existing circular saw with a 32 mm shaft, which is suitable for installing medium-sized saw blades. Alternatively, flat wood cutters can be used, the seat diameter of which is also 32 mm. IN in this case You only need to install a protective cover and a guide device for compact chip ejection.

Making a chopper yourself is an undertaking that requires certain tools and materials. You will need:

Sheet metal for the manufacture of casings, hoppers, protective screens.
Steel angle or channel to create a shredder frame.
Fastening elements - bolts with nuts necessary for connecting protection elements, installing a working element, etc.
Welding machine with electrodes.
Electric drill with a set of drills.
Grinder, hacksaw for metal.
Ruler, tape measure, scriber for marking.
Kerner, hammer.
Set of wrenches, screwdriver, pliers.
Can of paint, brush.

The above list is not exhaustive; depending on the designer’s intent, other materials or tools may be useful.

Shredder manufacturing procedure:

A frame is assembled from a corner or channel.
The cutting element is installed on the frame.
A platform is attached for mounting the electric motor with a tensioning device. If you plan to use a gasoline engine, the mounting is made based on its design.
The pulleys are installed and the drive belt is tensioned.
The protective cover is assembled and fixed on the frame.
It is recommended that the guide device for ejecting crushed material should not be permanently attached immediately, but that the installation should be checked in operation. Sometimes it turns out that the wood chips fly too far, which is inconvenient for the owner and greatly pollutes the area. The reflector is experimentally installed in the optimal position, after which it is finally attached.
Once assembled and tested, the device is painted to give it a neat and elegant appearance.

It often turns out that an error has crept into the working drawings, impairing the performance of the installation. Usually it comes down to the shape of the housing, which contributes to chips getting stuck in narrow places or irregular shape reflector. The consequence of this is excessive range or spread of the ejection, or, conversely, accumulation of crushed material at the outlet due to obstacles caused by incorrect reflector configuration. It is recommended not to completely assemble it right away, but to first carry out a test run of the installation and eliminate any deficiencies found.

Branch crusher made from improvised means

Some craftsmen use ready-made devices as a basis, for which they only need to make additional elements or details. Instead of powerful stationary motors, you can use an electric drill or grinder. Let's look at the most common crusher manufacturing options:

From the washing machine

An activator-type “washer” is an excellent “semi-finished product” for making a homemade shredder. You will need to dismantle the activator and install a knife on the motor shaft, the size of which is slightly smaller than the diameter of the inside of the tank. The principle of operation of the knife is similar to that used in a coffee grinder - horizontally installed plate with sharpened edges. A hole is made in the lower side of the tank to which the outlet casing is attached. While the shredder is operating, wood chips will enter the shredder. The design is quite simple and reliable, tested many times in practice.

Engine washing machine has a low power, rarely exceeding 500 watts, therefore with the help of such equipment it is possible to chop only straw or grass

From the Bulgarian

To make a shredder from a grinder, you will need a metal container, in the central part of the bottom of which a hole is made for installing a knife. The axis of the grinder is passed through this hole, and a knife is installed on it. The tool itself is fixed in a stationary state so that the knife rotates freely without touching the walls of the container. The rotation speed of the tool is quite high, so it is recommended to set it to a minimum so as not to end up with a “puree” of green mass.

From a drill

In order to use a drill as a grinder, you will need a stand (usually it is recommended to use a regular stool with a 12 mm hole in the central part of the seat). A bucket with a similar hole in the bottom is installed on top; to keep it stationary, it is attached to the stool with self-tapping screws. The knife, the size of which is slightly smaller than the diameter of the bottom of the bucket, is mounted on an axle inserted into a bushing with a bearing. The sleeve is attached to the bottom of the stool. A drill with a self-locking chuck is attached to the axle and started. The device is suitable for processing green mass in small volumes.

A homemade shredder for branches or grass stems allows you to speed up the process of chopping material before putting it into a compost pit or oven, mulching the soil, and when carrying out other work. The costs of creating a shredder are much lower than the costs of purchasing a finished product, and many design options from scrap materials and elements allow you to choose best option for this estate. Considering the occasional nature of using such a crusher, making the installation yourself is a profitable and simple undertaking, and the efficiency of the shredder depends only on the thoroughness of the work.

All photos from the article

Live in country house is somewhat different from the life of urban tenants, whose habitat in the home environment is limited only by the boundaries of their square meters, and the garden and vegetable garden are only on TV. The private sector requires care not only for the premises, but also for the garden plot, where branches, pruned in the garden and fallen leaves will constantly accumulate, which somehow need to be disposed of. And a good owner will certainly make a wood shredder with his own hands, so that this waste can be put to good use and not just burned in a fire.

Homemade garden shredder

I would immediately like to make a small digression regarding processed (shredded) branches and leaves - some may think: “Do I need this if I have something to heat the stove or even have gas heating?”

The fact is that such a derivative can be added to a compost pit and the decay process will go many times faster, but it can also be used for a gas generator boiler - such fuel will be perfect there. Therefore, we will tell you how you can make such a unit yourself, and show you a video on the topic in this article.

Necessary materials

The basis, or more precisely, the “nail” of our unit will be of the same diameter, of which approximately 15-25 pieces will be needed. At the same time, you don’t need to buy them in the store at all - old ones, which are removed from a hand-held electric circular saw when they become dull, are quite suitable for this. But if you want to process thick material, then it is best to use new saws.
Of course, to power the mechanism, you need an engine, and for this a diesel, carburetor or electric motor is suitable, the power of which will determine the performance of the structure.
To fix the saws as a chopper, we need a shaft in the form of an M20 threaded rod with nuts and washers.
In order to start the rotation of the shaft, you need a pulley - a good fit from a VAZ generator and a non-stretched belt.
All rotating parts must be mounted on bearings.
The shredder frame requires metal profiles (square, rectangle or pipe).
For the loading and processing hopper we will need sheet steel (preferably galvanized so that it does not rust).
Plastic washers for sealing (approximately 14-24 pieces).

A DIY Garden Shredder Guide

Note. If you want to buy a garden shredder in a store, they will most likely offer you a model with a crusher consisting of two or three knives - such designs cannot withstand heavy loads and become dull very quickly, after which they need to be sharpened, which is not very convenient.

But you are not limited by any production instructions, therefore, you can get rid of this disadvantage by increasing the number of cutting surfaces. Moreover, if circular saws become dull, you can simply remove the shaft and replace them with new ones by purchasing them at your nearest store.

We can use an internal diameter of 20 mm and it is quite natural that our stud will have the same thickness. Only the package cannot be assembled by pressing the disks close to each other; the teeth are always slightly wider than the blade itself, so you will not be able to assemble the saws tightly.

This is why you will need plastic washers - you can spread the discs a short distance, leaving a gap between the teeth of no more than 3 mm, so that the processed material does not fall between them.

Now it’s the turn to put a pulley from a VAZ generator or pump on the shaft. And in order for the axle to rotate, you put two bearings on it from the intermediate shaft of the same VAZ.

When the shaft with the saw package is ready, we need to weld a frame from profiled pipes along the width of the cutting structure and attach the rod from the walk-behind tractor to the frame. Now, in order for you to be able to change the tension of the drive belt, the engine must be installed with the ability to move. To make crushing easier, you can weld a thrust block from a scrap metal profile onto the frame—the branches will rest against it during processing.

We weld a casing made of sheet steel onto the cutting mechanism; galvanizing can also be used, but in this case, the welder must be a professional, since such sheets are usually very thin and are easy to burn through.

To load branches and leaves, we make a hopper with a socket - its height should be no less than the casing that is below. This bell should be comfortable for you, therefore, take into account the inclination of the funnel along the loaded branches.

A large loading hopper and a wide package of knives allow you to load fairly large branches without first sawing them into fragments - this is a significant difference between homemade
shredder from the factory, which is designed for the same purpose.

In addition, a factory garden shredder requires a certain degree of moisture from the material, and you will not be able to process wet leaves and branches there - this is prohibited by the manufacturer's instructions.

The whole point is that on a branded unit the engine is located under the knives and the moisture that will drain from the product will definitely fall on it, and it can simply short-circuit, whereas in our case the engine is located away from the crusher.

Conclusion

In conclusion, I would like to mention some more advantages of a homemade garden shredder. First of all, it's his low price, since it is assembled, in fact, from scrap materials. Secondly, it can be used in the fall as a crusher for fruits and berries - this is a bonus for winemakers!

This motto has already been adopted by the owners of quite large quantity private houses and gardens. You too can join the honorary list of innovative gardeners. To do this, you just need to relax after tiring hours self made and stock up on drawings that will allow you to create such a garden shredder with your own hands. According to experts, this will take you a minimum of cost and energy.

Of course, you can go to a specialized supermarket and purchase expensive and large equipment that will crush required quantity branches in a couple of minutes. But you must admit that it will be much more pleasant to make a garden shredder with your own hands by finding the right article on the Internet, and then use it for many years for its intended purpose. After all, depending on the situation, you can plant a whole garden of fruit trees that you will need to care for.

A garden shredder should not be low-powered and equipped with a small number of blades, otherwise you risk poor performance from your new equipment. It is better to assemble a device that will allow you to process branches with a diameter of 4 cm; the selected technical indicators of 2 cm will not be sufficient for similar works. For such equipment, it is necessary to select a powerful engine (some experts recommend a gasoline engine, which is more economical, others recommend an electric one). Most homemade craftsmen adopted the engine from the MB-1 walk-behind tractor.

In addition, in order to make high-quality equipment, you will have to buy a whole set of circular saws with carbide tips - from six to ten (about 25 pieces). As a result, you will achieve the desired cutting edge width of 8 cm.

Just keep in mind that circular saws must be made from good metal, otherwise you risk ruining everything yourself.

So, you're ready to get started. Now you need to weld the frame from steel pipes To install your motor, connect the motor to the chopper using a belt (you can find it in a car store), install separate cutting discs on a steel shaft (diameter 20mm) and place thin plastic washers between them. Experts advise installing the engine on the frame so that it can move relative to the circular saws and adjust the tension of the drive belt. The chopper frame is mounted on the walk-behind tractor rod and secured with bolts.

A persistent profile in the form of a bar will also make the work much easier. You can easily install it with your own hands on the frame of the electric garden shredder you are assembling. It will be much more pleasant to work with wood if you install a special compartment both at the top and bottom to receive the crushed product. In the lower part it will prevent possible scattering of crushed waste. Your device can now “absorb” not only wood, but also grass, tops and twigs, and, if necessary, vegetables, crushing them to the smallest pieces.

That’s basically all – your device is completely ready for use. It turns out that it is not at all difficult to make a garden branch chopper with your own hands. Just remember about safety precautions - no one has canceled them. As well as the fact that the used material should also at least be removed from the site and preferably disposed of.

A garden shredder is a mechanism designed for processing plant waste generated during grass mowing, sanitary or annual pruning of trees, grapes and various shrubs. The resulting small pieces of grass or branches can be used as livestock feed or fertilizer. The use of this unit allows gardeners, owners summer cottages and those who love beautiful lawns can get rid of organic debris faster and with less labor. The structure of the device is relatively simple, for this reason it can be assembled with your own hands without any special financial costs from old parts and scrap materials. This allows you to save on purchasing a ready-made factory device.

To independently assemble a grass and branch chopper (shredder) at home, you must first understand the structure of the mechanism, as well as the principle of its operation. This will help you assemble the equipment correctly and, if necessary, make changes to its design.

A homemade unit, designed for grinding mown grass and cut branches up to several centimeters thick, has the following main structural units:

engine;
knives mounted on the working shaft;
frame (usually metal);
protective casing;
a box designed to receive cut vegetation;
starting system.

The technique itself can be done in a stationary or mobile form. To create the latter option, you will additionally need wheels, as well as a handle. To make the frame, use metal corners or ready-made frames from workbenches. Boxes for processed vegetation are made from plastic buckets, tin, and bags. The protective casing around the knives should be thick and durable enough so as not to quickly wear out from the impact of grinding vegetation.

When processing plant debris, crushed pieces may fly out of the opening through which it is fed. Therefore, the neck is covered with a lid or simply with a cloth, for example, a bag.

The operation of the chopper is that rotation from the motor shaft is transmitted directly to the knives or through a chain/belt drive. The vegetation chopped by the blades enters the box. In this case, the final product is immediately ready for use.

By operating principle Some homemade shredders are comparable to a meat grinder (they suck in and then grind organic matter), while others are like a coffee grinder.

Varieties of engines for assembling homemade products

Used as a drive for homemade products electric and gasoline engines, taken from unused equipment. Each of these two options has its own advantages and disadvantages. Models with engine internal combustion more convenient in that their operation does not require a nearby power supply. But in general, they are more expensive and have a more complex design than their counterparts equipped with an electric motor. Therefore, it is easier to make electrical equipment, and also more compact.

The maximum thickness of cut branches that a branch chipper can grind depends on the power of the electric motor installed on it and the characteristics of the knives.

Models with a motor up to 1.5 kW are capable of grinding sticks up to 20 mm in diameter. They are designed for low intensity work.
If an electric motor of 3 to 4 kW is installed, then such units can chop branches up to 40 mm thick.
More powerful electric motors (over 4 kW) are used to make a shredder for wood with a diameter of 7-15 cm.

To create a homemade shredder, you can use electric motors from an angle grinder, washing machine, trimmer. They must be adapted to work from a stationary network with a voltage of 220 V. In order to grind material as thick as possible at home, it is recommended to equip the shredder with an electric motor of 1500 rpm with a power of about 3.5 kW. This parameter for internal combustion engines this corresponds to 5-6 horsepower.

Motor from an old washing machine

Types of cutting attachments used

Homemade products, like factory units, are equipped with cutting attachments of various types:

disc (with three blades);

milling;

milling-turbine (universal).

The first type is flat blades. When they rotate, they grind plant debris. If you have to process branches, then such blades quickly become dull. Milling knives are a cutting shaft in the form of gears from circular saws. They grind dry waste from branches and grass well, and clog the cutters with wet waste. Milling-turbine cutting attachments can cope with thick and undried branches, but making them yourself is difficult.

At home, knives from lawn mowers or made from wood saws are often used.

It should be taken into account that the installed cutting attachments directly depend on degree of processing of plant waste. The output is pieces of branches from 10 cm long or shavings or dust.

Garden shredder from washing machine

An old Soviet-made washing machine with a metal body is a technique that contains almost all the necessary parts for assembling a garden shredder. You only need knives with fasteners, as well as an extension cord.

To make a cutting attachment, you can use an old wood saw.

Tools you will need:

angle grinder;
pliers;
spanners;
screwdriver;
electric drill;
hammer;
tape measure with marker.

The washing machine motor has low power (about different models different) indicated in the instructions for household appliances or on the electric motor plate. Due to the fact that usually its value does not exceed 500 watts, with the help of the created unit it will be possible Grind only straw or grass.

A shredder from a washing machine is made like this.

The body of the machine is cut to height so that it is convenient to work with the unit.
At the bottom side, a rectangular hole is cut in it with a grinder, 20 cm wide and 7 cm high, intended for throwing out ground plants.
Around the slot, a kind of casing is made of tin, which will direct the herbal mass into the collection container, while preventing it from scattering to the sides.
They make legs.
Attach the body to the stand.
2 holes with a diameter of 7 mm are drilled on the electric motor shaft. Then a threaded bushing is placed on it, as well as holes at the end more than 5 cm long, securing it with bolts.
An electric motor is secured under the bottom of the box using studs and nuts.
Inside the casing, knives are secured to a sleeve, placing them above the grass ejection hole or at the same level with it.
The box is attached by welding or bolts to the stand.

The result will be a technique similar to the one shown in the photo below.

Start button suitable from a converted washing machine. You just need to make sure to connect the extension cord of sufficient length.

Homemade grass grinder from a grinder

A grass grinder made from a grinder is a fairly simple and quickly implemented option. To implement the project, you will need to stock up on the following parts and materials:

steel corners;
metal container (regular boiling);
homemade or ready-made knives (for example, from a lawn mower);
fasteners;
sheet metal.

Tools you will need:

electric drill;
welding machine and electrodes for it;
an angle grinder to cut corners;
spanners.

To assemble a shredder with your own hands on a corner base grinding machine, capable of grinding not only grass, but also branches up to 4 cm thick, it is recommended to use a power tool with a power of over 3 kW.

The creation of a grinding unit is carried out in the following sequence:

cut the corners into pieces with a grinder;
a frame resembling a chair is welded from them;
weld a shelf from a piece of sheet metal;
attach the grinder to the made frame (on the stand) with clamps, placing its shaft towards the top;
cut a hole about 10 by 10 cm in the side of the boil-out;
a sleeve, for example, made of tin, is attached to the slot, through which the ground plant mass will be dispensed from the container;
make a hole in the center at the bottom of the boil;
install the container on the angle grinder shaft and attach it with bolts or self-tapping screws to the metal frame;
Place the knife or disc on the angle grinder.

The result will be the design shown in the photo below.

The dimensions of the corners are selected individually to make it convenient to handle the mechanism.

It should be remembered that the frame must be stable. The safety of working with the device will depend on this.

Place a bucket or other container under the pipe for dispensing chopped grass with branches while working with the unit so that the processed plants do not fly away.

The created device can be improved. This will require attachment to the grinder shaft about 15 cm long with two knives: at the upper end and in the middle. The blades are separated by a mesh attached to the casing wall.

Grass cutter from trimmer

A garden shredder can be made using a gasoline or electric trimmer. In this case, the tool will work upside down. To create equipment designed to chop grass and thin twigs, you will need, in addition to a brush cutter with cutting attachments, the following materials:

plastic or metal container with a volume of at least 50 liters;
approximately 1 sq.m. steel mesh with small mesh size;
about 3 meters of metal tube (aluminum or steel) half an inch in diameter;
a piece of board or moisture-resistant chipboard, plywood of such width that the trimmer fits on it;
clamps that will attach the brush cutter to the wooden base;
self-tapping screws, bolts, nuts, washers;
wooden blocks (5 by 5 cm is enough).

To assemble a chopping mechanism from a trimmer, you will need to use the following tools and devices:

a screwdriver or screwdriver with bits;
electric drill with a set of drills for wood and metal;
an electric jigsaw with files for cutting metal or a manual equivalent;
hammer;
open-end or socket wrenches;
punch;
an anvil or a flat iron plate.

Punch needed to make it convenient to drill holes with an electric drill. This tool is pointed at the point where the metal needs to be drilled. Then it is hit with a hammer. The drill does not slip out of the resulting recess when drilling a metal part.

Preparatory activities

A grass cutter from a brush cutter is manufactured in a number of stages. Initially prepared in capacity where the grass and branches will be ground:

make markings on the bottom (along the perimeter) for four trapezoidal holes with rounded corners;
drill holes with a cross section of 1 cm in each drawn segment;
a jigsaw file is inserted into them and trapezoids are cut out;
process the cuts with a file or sandpaper;
a hole is drilled in the center of the bottom for the chopper shaft;
a circle is cut out of steel mesh with dimensions according to the diameter of the bottom;
using small scraps of boards or blocks, the prepared mesh fragment is secured to the container from below;
Legs for the container are made from metal tubes, attaching them to the tank using bolts.

The wooden pieces are fixed with self-tapping screws, twisting them from the inside of the tank into metal jumpers between the cut trapezoids. In this way, the mesh is securely attached to the bottom of the container.

Legs done in the following way:

bend the tubes in a vice or using a pipe bender in the shape of the letter “P”;
the ends of future supports are flattened with a hammer;
2 holes are drilled into them on each side (6.5 or 8.5 mm cross-section);
fit the workpieces to the bottom of the container and mark the points of bolted connections;
drill according to the hole mark;
using bolts with washers and nuts, attach to the footrest casing.

After preparing the casing, so that reduce dimensions created mechanism, perform the following operations:

disassemble the trimmer, disconnecting the motor, rod and cutting attachment from each other;
cut off a fragment approximately 20-40 centimeters long from the rod with the cable;
collect the lawn mower;
check the performance of the equipment.

Chopper assembly

If the trimmer works well after assembly, then it is used to create a grass grinder.

The motor of the brush cutter is attached to the board with clamps.
Fixed on wooden base a barbell using clamps and a handle from a brush cutter.
Connect the cutting attachment to the end of the rod, previously inserted into the hole at the bottom of the casing.
They start the mechanism and test it in operation.

After these steps, you will get a unit, the photograph of which is presented below.

If the trimmer used to assemble the shredder is equipped with a gasoline engine, then the motor is placed on the base so that it is convenient to fill in fuel, start the device and regulate its operation (speed).

Cutting attachments are equipped with knives or fishing line - this depends on the thickness of the plant stems being chopped.

What else can a chopper be made from?

There are many different options for creating garden shredders with your own hands: from the simplest ones, which only allow you to grind grass, to more structurally complex, powerful units designed for wood up to 10 cm thick. Accordingly, the practical implementation of the plan will require different details, different amounts of time and money.

To assemble equipment for processing plant waste, in addition to the considered options for old or unnecessary tools or equipment, you can use the following devices:

drill or hammer drill;
an old working vacuum cleaner;
unnecessary electric saw;
motor from the pump;
gasoline or electric walk-behind tractor;
any electric motor of suitable power.

A drill with a hammer drill, if you use them to chop grass, you don’t need to redo it at all. It is enough to do only nozzle with blades. The created device will work like a blender, grinding soft plant stems into a container in small portions.

The nuances of operating homemade equipment

A self-made shredder is essentially three in one: a chopper for branches, a straw cutter, and a mechanism for cutting grass. It helps to significantly facilitate household work associated with the disposal of plant waste, as well as feeding poultry and livestock.

If you have to process grass into small quantities, for example, for chickens, geese, ducks, then it is enough and completely simple devices, which work from muscular strength person, for example, a hand pruner.

For homemade electrical equipment, it is recommended to install separate differential machine, to provide reliable protection from defeat electric shock in case of unforeseen circumstances. In any case, when making a garden shredder yourself, you must follow safety regulations. It is also worth adhering to them during operation of the mechanism. Before working with equipment, it is recommended to wear goggles, suitable protective clothing and check that the structural elements are securely fastened. Should be taken into account when creating homemade unit the amount of work to be done, as well as the nature of the vegetation being processed, in order to select an engine required power and the desired design of knives. This will allow the completed device to cope with the assigned tasks without any problems.

When engaged in home gardening, summer residents are invariably faced with the need to dispose of various garden waste. You can simplify the disposal of such waste by using various specialized tools. Making a branch shredder with your own hands is not difficult, which will allow you to save on the purchase of expensive factory equipment.

Garden shredders have simple design; at making the right choice components used, it is not difficult to assemble the unit at home. You just need to decide on the design of the shredder - based on an electric or gasoline engine.

The design of a homemade garden shredder will consist of the following elements:

metal frame;
engine;
knives mounted on the shaft;
protective casing;
boxes for receiving crushed waste;
launch system.

You can make gardening tools in a mobile or stationary version. To make the frame, it is permissible to use a frame from a workbench or weld the structure yourself from a metal corner. The box for receiving crushed waste is made of tin or a plastic bucket. It is necessary to take care of high-quality protection of the cutting tool, which is responsible for grinding plant waste. A durable casing for a do-it-yourself branch chopper, drawings of which can be found on the Internet, is made from sheet steel or cut from a pipe of suitable size.

The operating principle of garden waste shredders is extremely simple and vaguely resembles the operation of a meat grinder or coffee grinder. On the shaft, which is connected through gears to the drive, there are numerous rotating knives that quickly grind the vegetation, after which the crushed waste enters a plastic box and is disposed of by the gardener.

The basis of the shredder for branches and leaves will be an electric or gasoline engine, the power of which is 5-7 horsepower. When using an electric motor, a drive with a power of 1.5-3 kW will be sufficient. Easiest to do electric shredder, which will be distinguished by its simplicity of design, reliability and durability. In the future, such equipment will not require any serious maintenance or repair.

DIY electric garden wood chippers use electric motors salvaged from old equipment. The performance of the shredder, as well as the ability to work with thick branches and solid waste, will directly depend on the motor power rating.

Shredders with a motor power of 1.5 kW are characterized by low productivity and are capable of grinding branches with a diameter of no more than 20 mm. Devices with a drive power of 3-4 kW will be an excellent choice for a personal plot, easily coping with both the utilization of grass and the grinding of branches 40 mm thick.

It is not recommended to use more powerful engines for the manufacture of homemade shredders, since such equipment will have a complex design, and working at high rotation speeds of the shredding mechanism is often problematic. To make a homemade shredder, you can use an electric motor from a trimmer, washing machine or grinder.

Homemade units and factory-made crushers use various types of cutting attachments. The choice of one type of cutting tool or another will depend on the drive power and the entire design of the device.

The most popular attachments are:

disk with blades;
milling;
milling-turbine type.

The simplest knot crushers are equipped with a disk cutting tool on which numerous flat blades are located. When rotating, they grind garden debris and do an excellent job with fallen leaves and grass.

Milling knives are made in the form of a gear, on which numerous circular saws are mounted. Such nozzles easily grind grass and branches, but it is necessary to monitor the moisture content of the crushed waste. Wet grass and leaves can clog the cutter, after which you will need to open the housing and clean the cutting edges.

Milling turbine attachments are distinguished by their versatility of use, easily coping with the grinding and disposal of grass, branches and large wood waste. Their disadvantage is the difficulty of making them yourself: most likely, you will need to purchase ready-made attachments from factory shredders.

The manufacture of such a device, if there is an appropriate circuit, is not particularly difficult. You just need to choose a working electric motor, the power of which will allow you to easily grind branches, grass and leaves in the future.

Homemade garden shredders for leaves and wood chips, which are made from an old washing machine, are popular. You can use not only an electric motor, but also a housing with a frame, which greatly simplifies the manufacture of equipment. It is possible to make a branch chopper for a walk-behind tractor with your own hands, which will be mounted on a cultivator and other mechanized equipment.

Tools you will need:

electric drill;
pliers;
Grinder;
wrench and screwdriver.

The electric motor power in old Soviet washing machines usually does not exceed 1 kW, so the shredder can only be used for chopping grass and fallen leaves. Cutting knives can be made from scraps of metal, which are sharpened and fixed on the electric motor shaft. You can also use factory attachments, which are distinguished by their quality and greatly simplify the manufacture of a homemade shredder.

The work algorithm will be as follows:

This simplest option grinder, for the manufacture of which any old Soviet washing machine is suitable. The summer resident can do all the work independently, having minimal experience working with an angle grinder and a welding machine.

A self-made grinder from a grinder is another simple option that won’t be difficult to implement. For work you will need the following tools and materials:

steel corner;
metal container;
fasteners;
purchased or homemade knives;
sheet metal;
welding machine;
electric drill;
angle grinder.

The power of the power tool will be sufficient for grinding leaves and processing branches of small thickness. It is recommended to use old grinders with a drive power of 3 kW to make a shredder.

Assembly is carried out in the following sequence:

Completed homemade device is distinguished by its simplicity, and thanks to the excellent power of the electric motor from the angle grinder, this homemade shredder branches and grass will cope with various garden waste. You can make knives yourself or purchase them already. ready-made options from a lawn mower-trimmer.

By making garden shredders for branches and grass with your own hands from a trimmer, grinder or drive from a washing machine, you can get functional and easy-to-use equipment that will allow you to easily dispose of various garden waste, including trimmed branches, fallen leaves, mown grass and other biological waste.

Making such equipment will not be particularly difficult. It is only necessary to decide on the design of the unit to be used and then, according to the available documentation, carefully weld and assemble a homemade chopper, which, if possible, will not be inferior to factory equipment.
