How to make a garden shredder. DIY garden shredder - more than reality! The choice of materials for the manufacture of grass chopper

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

Of course, you can go to a specialized supermarket and purchase expensive and large-sized equipment that will grind right amount 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 using it. long years by appointment. Indeed, depending on, you can plant a whole garden at your place. fruit trees that you need to take care of.

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

In addition, to make high-quality inventory, you will have to buy a whole set circular saws with hard-alloy nozzles - from six to ten (about 25 pieces). As a result, you will reach desired width cutting edge at 8 cm.

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

So, you are ready to get to work. Now you need to weld a frame of steel pipes to install your motor, connect the engine to the chopper using a belt (you can also find it in a car shop), install the cutting discs separately on a steel shaft (diameter 20mm) and lay thin plastic washers between them. Experts advise mounting the motor on a frame so that it can move relative to the saw blades and adjust the tension of the drive belt. The chopper frame is mounted on the walk-behind tractor bar and fixed with bolts.

A stubborn profile in the form of a bar will also make the work much easier. It can be easily installed by hand on the frame of the garden electric shredder you are assembling. It will be much more pleasant to work with wood if you install a special compartment both above and below to receive the crushed product. At the bottom, it will prevent possible scattering of crushed waste. Your device can now "absorb" not only wood, but also grass, tops and knots, and if necessary, vegetables, chopping them to the smallest pieces.

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

To make a branch chopper with your own hands, you need to study all their varieties. Depending on the volume of the processed material, the design of the required power should be selected. Do right choice in knife design.

During assembly, some components are made by hand. Standardized parts are purchased or used from end-of-life units. good option is the use of end-of-life devices. These include washing machine, grinder or walk-behind tractor.

The principle of operation of the unit

The schematic diagram of any branch chopper consists of nodes:

• engine;
• 1 or 2 working shafts;
• knives;
• receiving bunker;
• frames;
• protective cover.

The garden crusher is mounted on wheels. This creates the convenience of moving within the cottage.

While the engine is running, torque is transmitted to the shaft through a chain or belt. The knives located on them grind the branches that are fed through the receiving box. Shredded wood is formed, which is placed in compost pit. The principle of operation resembles the work of a meat grinder.

Industrial units for knife chopping of thick branches are produced with high power. This is not required in a suburban area. Therefore, for domestic needs, smaller branch cutters are made by hand.

Varieties of choppers

The basic arrangement of all types of wood shredders is the same. They differ only in engine power and the variety of knives.

Some designs have Gas engine, in others - electric. The first is more powerful, it is engaged in chopping large branches. Independent of power supply. Possesses greater mobility. Electric is weaker in power and remoteness of work depends on the length of the cable. But it is mobile due to its lightness.

Engines differ in power:

1. 1. Electric motor up to 1.5 kW. Able to chop branches up to 2 cm in diameter. Most processing is carried out in small areas.
2. 2. 3 - 4 kW. Cope with wood up to 4 cm. Used in small garden or cottage.
3. 3. 6 kW or more. The work is carried out in large farms. Trunks 10-15 cm in diameter are processed.

As a rule, a 4 kW engine is being installed on a home-made unit. It makes no sense to put more, because there will be a large consumption of electricity. To perform work on chopping branches on suburban area no such cost is required.

Dont Have special significance engine speed. The final amount of rotation of the knife shaft is 1500 rpm. It is regulated by the diameters of the pulleys.

Torque transmission is carried out using a chain, belt or directly by installing a cutting tool on the motor shaft.

Depending on the cutting tool, wood shredders are divided into:

1. 1. Double shaft type. This is a powerful unit that is able to chop large branches. Several knives are mounted on the shafts. The degree of wood grinding depends on their quantity.
2. 2. Installation with cutting disc. If the engine power is from 3 kW, then the knife is attached directly to its shaft. For units, the transmission link is used weaker.
3. 3. With circular saws from a circular saw. Refers to the simplest designs.

Frame manufacturing

Whatever the type of device, the frame has approximately the same design. It is welded from pipes and corners in accordance with the recommendations:

1. 1. The height size is selected based on the height of a person. To make it convenient to place the branches in the bunker.
2. 2. For the stability of the structure, its width is laid from 500 mm. The size of the length does not matter, it is a free value.
3. 3. For rigidity, crossbars are welded between the uprights.
4. 4. For ease of movement, wheels are installed at the bottom.

The frame size is coordinated with the engine parameters. It is impossible for him to speak out for her dimensions.

Two-shaft type step-by-step assembly

To make such an assembly, a drawing is created. He assists in the construction of the structure.

Are selected necessary materials and tools:

• engine;
• metal plates 10 mm thick - 2 pcs.;
• gears - 2 pcs;
• pulley - 2 pcs;
• shaft - 2 pcs;
• bearings - 5 pcs;
• knives;
• metal for the body;
• metal pipe;
• spanners,
• perforator;
• welding machine.

The frame is made in the usual way. If it is planned to install 4 knives, then a square blank is taken and shafts are machined from 2 sides to enter the bearing. For 3 knives you need round bar, in which cuts are made under them. Holes are drilled in the blanks.

Knives are attached to them. Mounting points are marked. Holes are drilled and threaded into them.

A drum is formed, which consists of 2 walls, 4 pins and a protective casing. To create the walls, metal 10 mm thick is used. They have 2 holes for bearings.

Bearings are installed on the shafts and knives are attached. With help keyed connection the pulley is fixed on the shaft. The keyway is formed with a torch. The whole mechanism is installed on the frame: the engine with a pulley and the drum. Between themselves, the pulleys are connected by a belt drive.

The receiver is being made. To do this, 4 sheets of metal are cut in the shape of a trapezoid. They are welded in the form of a box. It is mounted on bolts in front of the drum hole.

Disc chopper

A drawing is being prepared to create a disk chopper.

This device design is simpler.

For its manufacture, materials and tools are used:

• engine;
• pipes;
• sheet metal 5 mm thick;
• spanners;
• perforator.

It is better to buy factory-made knives, since they contain tool steel, hardened to 66 Rockwell units. To make them yourself, you need a spring, from which the workpiece is cut to the desired length. First, it heats up in the hearth, levels off, hardens and cools down. Then sharpening is carried out at an angle of 35-45 degrees. Holes are drilled in the body and the knives are ready for installation.

Alternatively, a pipe is used as a support for the unit. A cube is formed in the upper part, where all the details of the mechanism are attached, and the wheels below.

Metal is taken and a disk with a diameter of 400 mm is cut out of it. Holes are drilled in it for installing the shaft, as well as holes for attaching knives. Then the disc is mounted on the shaft and the entire assembly is attached to the motor.

The formation of the receiving compartment is carried out in the same manner as for the two-shaft apparatus.

From a set of circular saws

This type of construction is one of the simplest. The purchase of circular saws with carbide tips in the amount of 20-25 pieces is being made. This value can be increased. Knives are installed on the shaft. Between them are washers with a diameter of 20 mm. The length of the cutting surface is 80 mm.

dispose cutting tool closely impossible, because the thickness of the teeth more ground. Washers compensate for this value.

Before installing the knives on the shaft, a thread is cut. Then, nuts are clamped from 2 sides.

Frame formed in a standard way. Bearings are put on the shaft and fixed on the frame cross members.

The engine is installed, the chain is tensioned and the receiving hopper is installed.

Production from various devices

In order to make a branch chopper, you can use household appliances who have served their time. A slight refinement will make it possible to use them for a new purpose: to make a grain crusher or a branch chopper.

The main element in these devices is the engine. If it is in working condition, then it only needs to be supplemented with some details.

From Bulgarian

The workflow consists of the following steps:

1. 1. Capacity is selected.
2. 2. A hole is made at the bottom.
3. 3. The axis of the grinder is passed through it.
4. 4. A knife is installed from above.
5. 5. The tool is securely fixed.

When rotating, the knife should not touch the walls of the container. Branches fall asleep inside and the grinder turns on at minimum speed.

From a walk-behind tractor

To make a chopper from a walk-behind tractor, you will need materials and tools:

• walk-behind tractor;
• knives;
• bearing;
• channel;
• sheet material;
• electric planer;
• welding machine;
• a hammer;
• Bulgarian;
• drill;
• keys set.

The base is formed from a channel. A shaft from an electric planer, a knife and a pulley are installed on it. From the walk-behind tractor, torque is supplied through a belt drive to the pulley and shaft.

The receiving bunker is formed.

All structural elements are placed on a walk-behind tractor.

Making a branch chopper with your own hands gives significant savings. Factory models are expensive. At home, improvised means are adapted for this. Even if you have to purchase some components or give them for manufacturing, it will still be much cheaper than a purchased product.

let's consider different kinds and designs of garden shredders for twigs, wood chips, grass and grain, capable of handling any type of vegetable waste. For you, we have collected a selection of drawings and instructions for making a do-it-yourself knife garden shredder.

There are always a lot of cut branches, grass, tops and other plant waste in the garden. You can collect them and burn them, you can put them in a huge pile in the hope that someday you will get compost, or you can prepare raw materials for quick production. organic fertilizer, for introducing wood chips into the soil in order to improve its structure, you can get an excellent mulch or fuel for the boiler. To do this, you need a garden shredder, which you can buy, or you can do it yourself.

Advice! Protect your hands and eyes when operating the shredder, especially if you are shredding solid waste. Glasses and leather gloves will protect you from injury.

Types of garden shredders, main components and elements

Shredders consist of a cutting mechanism, a drive, a loading hopper and a frame with a sheathing. In addition, they can be equipped with a hopper of crushed organic matter. Of the auxiliary means: a pusher and a sieve, which is used to obtain a certain fraction of wood chips. The residue on the sieve is sent for re-grinding.

Garden shredders are classified according to the type of cutting system and the type of drive.

Cutting systems

Commercially available chippers may have cutting systems:

• roll - branches and bushes;
• hammer - thin branches;
• milling - solid vegetable raw materials;
• with a rotating turbine - thick branches;
• knife - universal;
• trimmer (fishing line instead of knives) - grass, tops.

1 - hammer grinder; 2 - milling grinder; 3 - chopper with milling-turbine knives; 4 - knife disk chopper

There are other designs as well. For self-manufacturing suitable knife and type-setting of circular saws. The most common are knife blades, and the knives can be fixed on a massive disk in two, three or more pieces, or rotate towards each other in a two-roll design.

type of drive

Garden shredders can be powered by electricity or use two- and four-stroke gasoline engines. In practice, when making a do-it-yourself unit, they use an engine from a walk-behind tractor, which is idle for most of the year, or remove the motor from an unnecessary household appliances. The main thing at the same time is that the power is sufficient - not lower than 1.1 kW. If there is nothing suitable, you can buy a new engine, but in this case, the benefits of a homemade chopper are no longer so tangible compared to a purchased product.

Some shredders that process exceptionally soft raw materials, such as succulent animal feed, may not be driven and run on human muscle effort. Below are drawings of shredders that you can do yourself.

Homemade hand choppers. A - two-knife chopper: 1 - knives; 2 - counter-cutting plates. B - multi-knife greens chopper: 1 - knives; 2 - counter-cutting plates; 3 - base frame. B - root crop grinder: 1 - shell; 2 - bearing; 3 - drum; 4 - cross; 5 - handle; 6 - end wall of the body; 7 - shield; 8 - pitched tray board; 9 - stand; ten - side wall corps

In the first picture, the knives are made from old, one-sidedly sharpened saws; in the second, the knives and blades are made from saw blades. On the knives, oblique teeth are machined, like a saw, in 5 mm increments. Both shredders are equipped with long handles for lighter effort. The working part of the third structure is made in the form of a drum with notches, the sharp edges of which stick out.

Drawings of various designs of garden shredders

Consider several designs of shredders that you can assemble yourself.

Hammer grinder can crush branches, straw, corn stalks, grain.

1 - loading hopper (sheet δ1 mm); 2 - edging the neck of the loading hopper (corner 25x25); 3 - damper/valve (sheet δ1 mm); 4 - M6 bolt for screed (8 pcs.); 5 - framing the loading opening in the body (an equal-shelf corner 25 mm); 6 - hairpin M8 (8 pcs.); 7 - outer drum of the body (pipe Ø 270x6); 8 - stator with grooves (pipe Ø 258x6); 9 and 20 - hammers and spacers (sheet δ3 mm, hardened to hardness HRC 45-47, 72 pcs. and 70 pcs., respectively); 10 - latch Ø 3 (4 pcs.); 11 - M20 nut with spring washer; 12 - axis of the hammers (circle Ø 22, 4 pcs.); 13, 14 - piping piping (equal-shelf angle 25 mm); 15, 19 - gaskets (rubber, sheet δ3 mm); 16 - M8 nut for fastening the flange (8 pcs); 17 - hammer rotor; 18 — flange (sheet δ5 mm, 2 pieces); 21 - retainer; 22 - drive shaft

Cutting Tool - Circular Saw Pack

A pack of 15-30 saw blades mounted on a shaft is one option for a shredder cutting system. Some craftsmen point out that the saw teeth quickly become clogged with plant matter. Others claim that they have achieved good work of the tool empirically - by setting teeth differently relative to neighboring saws. Since the carbide teeth are thicker than the blade itself, thin separators made of metal (for example, washers) or plastic must be installed between the saws, and the entire package is clamped with nuts.

Pack of 15 saws on the shaft

As a drive, you can use a low-power walk-behind tractor, pulleys and bearings - used parts from a VAZ car. Boot hopper - truncated pyramid, the outlet is small to prevent the human hand from passing through. It is better to make the frame for the chopper higher in order to remove the crushed raw materials less often.

Two-roll chopper

This chopper cuts branches into measured lengths from 2 to 8 cm, convenient for heating a sauna or wood-fired heating boiler. Its design consists of two shafts with knives - 3-4 pieces per shaft, rigidly fixed with bolts. Knives can be machined from a KamAZ or MAZ spring. If you can find a bulldozer knife, that's fine too. The shafts are fixed on massive sheets in parallel, at a distance sufficient for the knives to cut off the branch, but not to cling to each other. The free rotation of the shafts is provided by bearings, and their synchronization is achieved by a gear clutch moving with the help of a belt (chain) from the engine. To drive this grinder, it is advisable to use a high-power engine, but low speed.

If you want to create a mobile chopper, you need to provide wheel mounts on the frame.

The video shows a chopper with gears: driven gears - from the MTZ shank, fitted to right size, the drive (gear for transmitting torque to the shafts) was found by selection.

Making a garden shredder with your own hands

The most structurally simple and inexpensive chopper can be made from a disk with knives fixed on it, an engine, a frame and a hopper. The disk and knives can be turned on your own, ordered from a turner, or bought parts in a store. A cultivator engine is suitable as a drive, and it is not difficult to weld the frame and the hopper yourself.

Depending on how many knives are used and how they are set, the fraction of the resulting mulch may be different. The drawing below shows basic design such a chopper: a disk with four knives is installed vertically. Also, the design works well if the disk is fixed at an angle to the horizontal, and there are only 1 or 2 knives.

Assembly drawing: 1 - knives 4 pcs.; 2 - disk cutter; 3 - bearings No. 307

Operating procedure:

1. Buy, order or grind your own disk with knives. The angle of sharpening knives is 35-45 degrees. The knife blade should have holes for bolts for attaching to the blade. It is important to correctly set the knives and secure them with bolts and stops.
2. Weld the frame, taking into account the fasteners for the drive and other elements.
3. Push the disc onto the drive shaft and secure.
4. Weld the feeding hopper and, if necessary, the receiving hopper of the chopped mass.
5. Collect all the elements on the frame.

If the frame is mounted on wheels, then the structure becomes mobile.

An experienced gardener knows perfectly well that every autumn and spring you need to cut tree branches and clean them. But branches from such pruning are very inconvenient waste. Collected in one pile, they take up a lot of space, and you can’t put them all in the oven at once. And so it takes a long time to chop them with an ax or saw them. Most suitable option for a young owner - make a branch chopper with your own hands.

Such structures in everyday life are called differently. For example, the names of a wood chipper, a shredder, a wood chipper or a wood chipper are known. But that's not all. And despite the many names, the design and structure of such devices almost always remain identical.

They consist of the following elements:

In fact, the difference between many models is in the design of the cutting mechanism, and all other parts have only different sizes.

Basically, the following solutions are used to create a crushing system:

In order to increase the torque and power during cutting, a flywheel is used for such designs, which is mounted on the free part of the shaft. But for a disk crusher, it makes no sense to fix it, since the crusher disk itself acts as a flywheel.

Recycled branches are very often used by gardeners as a basis for compost. It is also possible to make braces from such shavings and heat the house or heat them directly with shavings.

When you choose the type of construction, you can safely proceed to the support of all necessary details and tools.

Choice of engine and belt drive

How thick the branches can be processed will directly depend on the engine power. Such a motor can be purchased on the market, and desired parameters and specifications. But it is better to remove the engine from old technology or buy. Thus, you can save a lot of money.

For acceptance right decision For this choice, you need to listen to a few tips:

The engine speed when choosing is not so important, since they can be increased by a pulley due to a belt drive.

In order for the branch cutter to successfully process tree waste, it is necessary to ensure that the engine speed is at least 1500 per minute. In this case, it is not the speed of the knives that matters, but the torque or the applied force. The distance between the pulleys also does not play a big role. The only nuance in this case may be a decrease in efficiency and belt tension force.

Before ordering the production of pulleys from a turner, you need to think about the purposes for which such a design will be used. Perhaps it makes sense to make several streams in the pulley, with the help of which it will be possible to easily change the speed of the cutting shaft. For example, you can set it to lower speeds when working with grass and corn stalks, and to high speeds when processing branches from trees.

Necessary materials

The ideal option to save money when choosing and preparing all components is to find them and remove them from old equipment. It is not so difficult to find them in the dacha economy.

To install saws on the shaft, you need to cut the thread. As a flywheel, you can use a steel disk 1 centimeter thick. how Alternative option you can use a ready-made flywheel from agricultural machinery or a conventional VAZ car. You also need to prepare base plate for branches 1 cm thick. It can be cut from steel plate.

Frame production

Regardless of the chosen type of construction and its motor, in any case, you need to make a frame for it. It consists of a frame on which the entire mechanism and a knife switch are installed.

It can be welded from squares and profile pipes using the following guidelines:

Before creating shredder drawings with your own hands, you need to foresee the location of the engine. It must be placed inside the frame so that it does not protrude beyond the edges. This applies to all models.

The most difficult operation in the production of such an apparatus is the turning of the shaft and the milling of the knives from the spring and their sharpening. These services will cost money, since it is unlikely that you will be able to do them yourself. This task can be solved more easily if it is possible to remove a solid shaft from old equipment, for example, from a circular saw.

As an alternative for trimming chips, you can use it yourself circular saw. You need to install a cutting mechanism on the circular drive and you're done. Also, the device can also be powered by a mini tractor engine, you just need to make the correct belt drive.

What is the purpose of a trash shredder in a summer cottage? What are these devices? Which is better - buy a ready-made unit or make a homemade one? Finally, how to make a DIY garden shredder? Let's look for answers together.

What it is

Under the names "garden shredder", "chipper" or "garden shredder" hides the same device - mechanical device for the disposal of vegetable waste.

Why is it needed?

• For processing haulm and weeds into compost. Chopped greens rot faster; in addition, it occupies a much smaller volume in .
• For soil mulching. Thus, we prevent the development of weeds, prevent overdrying of the soil due to evaporation, and at the same time we introduce fertilizers that will be gradually processed and enrich the earth with useful additives.

Help: mulching - backfilling the soil with mulch (crushed waste of biological origin).
The method became widespread in Eastern European countries in the 17th century.

• To automate the operation of solid fuel heating equipment.

Main problem solid fuel stoves and boilers - the need for frequent manual loading of the furnace - is partially solved in pellet units, where fuel is dosed by loading it into the bunker and gradually supplying it to the combustion zone.

Pellets (granules of pressed sawdust) can be successfully replaced with chopped pruned branches, shrub trunks and other wood waste.

Classification

Stationary chippers can be classified as follows:

By energy source

Electrical devices require a power supply of 2 to 6 kilowatts. A moderate price is combined with low weight and relative compactness: for example, the typical weight of a chipper with a 40-liter plastic container and a 2.5 kW motor is 10-12 kg at a cost of 6-8 thousand rubles.

For reference: a typical electric unit is designed for chopping branches with a diameter of up to 40 - 45 millimeters.

The shredders equipped with gasoline engines have more power, which allows them to grind large branches and branches. In addition, they are more autonomous: the user is no longer bound hand and foot by the length of the power cord.

Of course, the presence of a powerful engine and a gas tank inevitably affects the retail price, dimensions, and weight.

Here are the characteristics of a fairly typical Craftsman 77605 unit:

According to the grinding method

Waste shredding can be performed:

• Trimmer line. The absence of steel knives means low weight and increased safety of the device; however, for obvious reasons, it cannot chop branches and bushes.

Useful: the English-language instructions for such a device usually use the definition "Flex-a-Line" (from flex - flexible and line - line).

• Turbine. The blades are located at an oblique angle to the axis of rotation and are capable of shredding branches up to 45 mm thick. Due to the relatively small diameter of the turbine blade, the force on it can be significant with moderate engine power.
• Rolls. With a small motor power, they are able to grind fairly large branches; however, the performance of the device will be small.
• A knife rotating in the same plane. This scheme is one of the simplest and most popular. In most cases, making a garden shredder with your own hands is practiced using it.
• Cutting cutter. It is ideal for processing large wood waste; at the same time, the diameter of the crushed branches and branches is limited only by the size of the cutter.
• Gears with sharp teeth. The circuit guarantees a minimum noise level; however, it does not handle soft waste well.

Self-manufacturing

We must immediately admit that there are no detailed drawings of a do-it-yourself garden shredder in our article. The reason is simple and obvious: the production of handicraft units of this type in our country has not yet been put on stream; a single chipper, as a rule, is made according to the principle "I blinded you from what was."

Circular saw cutter

The role of the cutter is performed by a package of 20 - 25 circular saws with a diameter of 165 - 180 mm with carbide tips. Since a gap is needed between the saws, the package is assembled with alternating saws with 4 mm thick PTFE washers.

The package is assembled on a threaded stud M20 (the size is dictated by the diameter mounting hole saw) and crimped with a pair of nuts with wide washers.

A couple more details are perfect for this size, which are easy to find on car disassembly:

• A pulley from a VAZ generator, ruthlessly devoid of fan blades.
• Bearings of the intermediate shaft from the VAZ gearbox.

The frame can be either welded from a channel or corrugated pipe, or assembled with bolts.

What is used as a source of mechanical energy?

• Electric motor with a power of 1.5 - 3 kW. It is fixed movably, with bolts through the grooves in the frame; this will help tighten the loose belt or replace it.

• Motor plow with a power take-off shaft.
• Any gasoline engine (for example, dismantled from an old moped).

Another simple and elegant solution is a do-it-yourself garden chopper from a grinder.

1. Instead of a cutting wheel, a lawn mower blade is installed. If the diameter of the mounting hole does not match, it is simply bored with a round file (of course, evenly in all directions, so as not to get an imbalance and the vibration associated with it during operation). (See also the article.)

1. The grinder is attached to the frame. This can be done with a pair of metal clamps directly behind its body; somewhat less reliable will be the mount for the protective cover.

Problem of choice

So what to choose - on a purchased or home-made design?

Pros of buying

• You have at your disposal completely finished device, which does not require any finishing touches and modifications and is supplied with a factory warranty. In case of misuse and modification of the same angle grinder, on the contrary, you automatically lose the guarantee for it.
• Manufacturers are concerned about user safety. Protective covers prevent you from being seriously injured when shredding garbage; but cripple when using homemade unit- lighter than light.
• However, the difference in costs between both scenarios is rather insignificant. A 2.5 kW electric chipper costs about the same as a grinder of the same power from a decent manufacturer (Makita, Metabo, Bosh).

The advantages of self-production

They come down to more mechanical strength and device resiliency. In addition, the notorious safety covers often make the use of a chipper a breeze: large branches, for example, have to be pre-chopped by hand.

Conclusion

We hope that the material presented to the attention of the reader will be useful. The video in this article will allow you to more clearly get acquainted with how a do-it-yourself garden chopper is made from a grinder. Success in creative work!
