Homemade herb grinder ☘ from a washing machine and simple instructions for craftsmen

How to make your own herb grinders

Grinding weeds is a labor-intensive process, which can be greatly simplified by making a device. The basis of the unit is a bucket, a washing machine, and power tools.

From the bucket

The bucket is bolted to the tabletop. To fix the motor and output the shaft where the knife is installed, holes are drilled in the bottom. A hole is made in the side of the container and covered with metal plates. This is the outlet for chopped grass.

When connecting the motor to a 220 V power source, the knives will rotate quickly, so it is recommended to connect to 40 V. The power source is a car battery.

From a vacuum cleaner

The design is complex, so you can’t do it without tools. The device is made from Typhoon vacuum cleaners. The electrical device is easy to use. The design of the vacuum cleaner allows for the release of chopped greenery without turning off the power.

If there is no Typhoon, install a motor of 180 W. Hacksaw blades are used as blades. A sleeve for mounting blades 4 cm long is cut into the wall of the housing.

Holes are made in the housing for the platform where the finished unit is installed. The engine is mounted at the bottom of the structure. The knives are screwed on with nuts.

From the washing machine

The unit is identical to that made from a vacuum cleaner. Initially, the washing machine tank is cut off. The height of the container in which the raw materials are placed should be up to 60 centimeters. The top hole of the tank will require a cover or rubber casing. Otherwise, the grass will fly in different directions.

A metal corner 50 cm long will be required to install the legs. Holes for bolts are made in it. Knives are attached to the axle. They can be installed in several rows. They are fixed with bolts or self-tapping screws.

Several holes are drilled on the sleeve. Their diameter must be at least 7 mm. Connect the bushing to the engine with bolts. To install the engine, the housing is turned over and several studs are prepared. Several holes must be made in the housing (depending on the number of clamps). The blades are put on the sleeve, being sure to fix it. This can be done with ordinary nuts.

The blades should not touch the inside of the container or become loose.

The power cable is connected to the motor contacts. In this case, it is necessary to ensure that the color of the insulation of the conductors matches. The connection is covered with insulating tape or silicone tube.

A hole is cut in the container to throw out the chopped greens. The outlet is located 20 mm below the level of the knives. Finally, the device is installed on a stand, and the legs are attached to the metal axis.

To use this unit, grounding is required.

From the Bulgarian

Take an angle grinder with any power rating.

First, they assemble the platform from the box. To make it I use wood or metal. A cutout in the form of an arch is made in one of the sides of the structure.
A hole is cut into the bottom of the box. It should be 50-70 mm larger than the working part of the power tool.
The grinder is attached from the inside of the box. In this case, the blades are located above the bottom. For fixation, it is recommended to use flexible clamps or clamps.
The bottom of a metal bucket is cut out. Install it above the knives. Fix the bucket with brackets and metal corners, securing it with hardware, such as bolts and nuts.

How it works: put weeds in a container and turn on the grinder. Rotating knives chop the weeds, which, after chopping, fall into the box. Remove the crushed feed with a shovel.

From a drill

They create a grass cutter based on a steel body or a hopper. The design is complemented by a protective cover, knives, shaft, stool, bearings with a housing.

A hole is drilled in the stool. Its diameter should be 12 cm. From the inside of the stool, fix the body, and then the bearings.
Holes are drilled in an old bucket (12 cm in diameter). It is placed on a stool and screwed with hardware.
P18 steel is used to create a diamond-shaped blade. It cuts fresh grass better. It is recommended to sharpen the edge at an angle.
The blades are secured to a shaft inserted into a bearing.
At the bottom of the stool, a drill is connected, which is connected to the shaft shank using a clamping chuck.

The grass is placed in a bucket and then the drill is turned on. After grinding the raw materials, the tool is removed.

How to make your own grass cutter

A grass cutter will always help to chop up the grass; in artisanal conditions it is not that difficult to do. After all, gardeners know how important it is to add organic fertilizers to the soil, enriching and nourishing the soil with the necessary substances.

Finely crushed grass clippings are a beautiful organic component for creating compost, and they are also spread out for mulching. By feeding on organic matter, the soil is saturated with essential micronutrients and becomes more fertile. Flowers, fruits and vegetables grow well on such soil. It is worth a little effort and doing in your own garden that all that remains is to provide our client with the necessary conditions for feeding the necessary plants.

If the area of cultivated land is quite significant and requires a lot of compost, then it is necessary to process the grass in huge volumes. You can cope with a small number of mown plants, of course, using a fairly common device - a chopper. Peasants have been using it for quite a long time, because mowed and crushed grass is needed not only to nourish the soil, but also to feed poultry and livestock. This invention is essentially an iron triangle that fits onto a holder. At the bottom it is equipped with a sharp edge, which crushes the grass when struck. If the amount of work is large and it will be done over and over again, then it makes sense to purchase, or in other words, make an automatic weed grinder on your own. It is no secret that folk craftsmen invent and make equipment from such means at hand that it is difficult to immediately figure out how the mechanism works.

You can make a grass cutter for grass with your own hands from a washing machine , a vacuum cleaner, an ordinary drill and a grinder saw. Some specialists assemble such units from unnecessary electronic devices; the main thing is to know what parts are needed and have an idea of the operating mechanism of any hay chopper.

Which motor should I get?

It is more convenient to work with old washing machines - Oka and Fairy are ideal. Top-loading barrel-shaped models with a bottom-mounted motor are easy to transport.

Expert opinion

Vladislav Ponomarev

Design engineer, inventor

A suitable motor has the following characteristics - power 180 W, engine speed 1350-1420 rpm.

Fairy models have a centrifuge, so the motor makes more revolutions, up to 2850 per minute, but the power is lower. The body is plastic and fragile. From Fairy models they take only the engine, the tank is made from an empty iron barrel, and knives are purchased additionally.

How to make a barrel sauna with your own hands, detailed instructions and drawings

The advantages of having a unit are obvious - the ability to process any volume of grass in a short time. A grass cutter is needed not only by gardeners, but also by owners of subsidiary farms - ground green raw materials are added to food for livestock and poultry.

Garden herb grinder

The homemade grass shredder you create depends on how much grass will need to be processed (disposal of garden waste, for compost, for livestock feed). Basically, it is not much different from a meat grinder, only for grass and hay and straw, in any case, the operating principle is the same.

Types of herb grinders:

different in power, depending on how much grass needs to be processed. With great power they can even handle small knots;
different types of knives - disc knives (blades that crush garden waste when rotating), milling knives (gears that, when rotating, tighten the material and automatically grind it);
different types of operation - on gasoline (maintenance is more expensive) or electricity (the device is tied to an existing outlet);
stationary type or mobile (lawn mower type).

From the washing machine

In itself, it is an excellent volumetric container for hay, grass, straw, etc. The principle of this chopper is similar to a food processor.

Necessary:

several knives placed in a cylindrical container;
an additional container for the upper part of the unit, into which hay, grass, and straw will be supplied;
an additional hole in the side so that there is a place for recycled material to flow from;
receiver of finished products (bucket, box, etc.).

From a vacuum cleaner

All you need is the vacuum cleaner body and its motor.

You will need:

the engine power can be equal to 180 W, this is enough;
fasten knives from unnecessary hacksaws with nuts to a threaded sleeve (approximate length - 40 mm). Secure at the bottom of the container and bolt above the knives;
try to make a hole for chopped grass under the legs or in the side;
To protect the electric motor, the base must be stable.

From the Bulgarian

The principle of creating a homemade grass grinder from a grinder, as in previous units:

select a container;
drill a hole in the bottom to install the cutting unit;
make a metal base and attach an angle grinder to it, carefully securing it with clamps.

Types of Shredders

Such units for processing grass are divided according to only 2 main criteria:

Type, as well as power of the power plant.
The blade system used.

It is worth examining each point in detail.

engine's type

You can assemble a grass chopper for chickens or other livestock using an electric or gasoline power plant.

Electric

Homemade grass shredders equipped with an electric motor are characterized by light weight, quiet operation, and a complete absence of emissions. However, the main disadvantage of such units is the lack of mobility, since they operate only from the network. On average, the power of such devices varies between 2-5 kW. Because of this, such models are among the cheaper options.

Benzinov

The most common factory shredders are equipped with a gasoline engine. This allows such a device to be moved to any point, despite the heavier and more massive structure.

In addition to its mass is added the capacity of the fuel tank that powers the gasoline engine. However, such power plants are more powerful than electric ones. As a result, the minimum cost of such units starts from $750, although they are much more productive. But they are often chosen by large agricultural companies where there is a large amount of work.

An additional criterion is the power of power plants. The main indicator of this type is the confirmed engine power. On average it is 4-7 hp. In addition, more advanced models have a reverse function.

Using reverse motion allows you to free the working container if it is blocked by too much grass or branches.

Types of cutting parts

When you need to assemble a grass crusher with your own hands, the cutting part is considered an important element in its design. The following types are used:

Equipped with 2 or more knives at the same time. The simplest models are those that have 2 cutting blades located in a horizontal plane. Units of this type are used to chop grass or small branches with a diameter not exceeding 2.5 cm. Models are more complex, have 4 or 6 knives located in both planes and are capable of chopping larger branches.
Having a worm crusher. In such units, the cutting element has the shape of a screw, similar to that used in a meat grinder. However, it is installed vertically and the number of screws in it is slightly smaller. Such models work very quickly and allow you to chop grass, as well as branches whose diameter does not exceed 4 cm.
A cylindrical unit equipped with many knives. Such models are also called “multi-blade cutters”. Today it is used only by Bosch. This shredder is a universal unit that can process almost any type of grass, as well as small branches. The disadvantage may be that vines get wrapped around it when the knives become dull.
Cutting shaft. Its efficiency for chopping grass is extremely low, so it is mainly used for processing branches whose size is less than 8 cm.

The choice of a suitable cutting unit option is determined by the tasks for which the device is purchased or assembled. It is important to understand all the positive and negative aspects that each type of knife has.

Main components of a garden shredder

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 sawn branches up to several centimeters thick, has the following main structural components:

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

The equipment itself can be made stationary or mobile. 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.

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.

According to the principle of operation, some homemade shredders are comparable to a meat grinder (they draw in and then grind organic matter), while others are comparable to a coffee grinder.

Homemade shredder

The creation of such a product is carried out in stages in several steps:

First, the type of unit is determined and a drawing is generated.
Next comes the selection of all the parts, as well as the preparation of tools.
After this, installation takes place according to the drawing of the entire unit, followed by testing.

It is important to clearly provide for the dimensions of all components and assemblies in such a design. Otherwise, the future device will be impossible to assemble or various parts will need to be additionally adjusted.

Tools

To carry out assembly and installation work you will need:

Hacksaw, as well as a circular knife.
Extension cord, at least 5 meters long.
Metal corners, as well as other fasteners.
Locksmith kit.
Drill, as well as grinder.

If you have experience working with a welding machine, it is worth preparing it too.

Details

To assemble such a unit yourself, you need to prepare:

Power plant.
Knives or discs.
Bolts and nuts as fasteners.
Shaft.
Container.
A frame that plays a protective role.

From the washing machine

To create such a unit, you first need to prepare drawings. A do-it-yourself grass cutter from a washing machine is also partially assembled from parts from a vacuum cleaner. But you only need to take the body from it if it is metal. Additionally, to construct a homemade unit you will need:

Power plant from the washing machine.
Knives taken from a lawnmower.
A container where the chopped grass will be collected.
Steel corners used for mounting the frame.
Fastening elements: bolts and screws.

In order for a homemade chopping device to be completely safe for use, it is important to properly approach the creation of a durable body, high-quality fastening of knives, and also impart stability to the entire structure. The step-by-step installation process of the unit is as follows:

First you should prepare the main working container, which should be metal. In this case, it is a housing from a vacuum cleaner, where a hole is made in the bottom for attaching the power unit. Additionally, it is worth making a window through which the processed grass will come out.
The motor from the washing machine must be firmly mounted on the shaft, where the knives will be attached in the future. Some craftsmen make it themselves using steel sheets.
A container is attached to the top through which the grass will be supplied.
A frame formed from metal corners. It is worthwhile to carefully approach the creation of a stable and strong structure.

To ensure that all stages are completed correctly, and that various small details are not missed, you must always have working drawings in front of you. The power of the finished device will allow you to grind large volumes of grass. In addition, it can also be used for processing hay.

From the Bulgarian

Another option involves creating a grass cutter from a grinder with your own hands. For this purpose, you will need to first prepare:

Bulgarian.
A metal container into which the material will be supplied.
Knives taken from a lawnmower.
Steel angles required for platform installation.

The process of creating such a unit is as follows:

First, the frame is welded, for which corners are used. It is important at this stage to lay down the weight of all the main elements. How well the frame is made largely determines the safety of using the shredder.
Next, the grinder is mounted to the frame so that the shaft is located on top.
Now a container is installed on top of the shaft, where the crushing itself will be carried out.
In order to hold the grass in the tank, metal frames are mounted in it.
Next, the knives are connected to the shaft.
To make it more convenient to remove the chopped mass in the future, a metal sleeve is created in the design, through which the grass will move into the collection container.

What is silo used for?

Many gardeners living outside the city grow not only vegetables and fruits in their dachas, but also keep chickens, pheasants, quails, rabbits and various domestic animals. Chopped grass silage can become an excellent food for pets; you just need to make sure that your farm has an appropriate chopper that can easily grind grass and hay.

Experienced gardeners use such ground grass as mulch and first-class organic fertilizer. You only need to ensure that the grass is chopped as finely as possible, as a result of which the layer of mulch will be dense, which is necessary to retain moisture and heat in the ground.

With the help of such universal equipment, you can easily grind cereals, vegetables and fruits, which allows you to make high-quality feed for livestock, eliminating the need to purchase expensive feed.

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 make only a nozzle with blades. The created device will work like a blender, grinding soft plant stems into a container in small portions.

Design and principle of operation of a grass chopper

To dispose of grass and thin twigs from a small area, gardeners usually use a cutting tool. But manual labor is not effective for processing large quantities of green waste. An unnecessary or non-working washing machine will do well as the basis for a common model of a homemade shredder. It will work on the principle of a food processor. Key nodes:

shaft with radially fixed knives;
engine;
receiving tank;
container for collecting processed mass;
frame.

The shredder model involves using a metal tank from a Soviet-style washing machine as a receiving container. For example, from Oka or Fairy. The grass will be loaded into this container and ground in it with a knife. The body of a Typhoon vacuum cleaner can also become a tank.

Homemade shredder

Tools and consumables for the chopper:

a circular knife or hacksaw to cut blades out of it;
wire with plug;
metal corner;
connecting parts;
drill;
Bulgarian;
welding machine;
locksmith kit.

Advice. A circular blade is the best option for a homemade shredder. Other designs must be tested in practice as they may not cope with thatch or thin branches.

Drawings, dimensions and diagrams of grass grinders

Before making any design, create a sketch. A DIY garden electric herb grinder is made according to the drawing. The body is made from a gas cylinder, a 50-liter barrel or a 20-liter bucket. Cover the top with a lid. To rotate the shaft with knives, motors from washing machines, vacuum cleaners, pumps and other household electrical appliances are used.

The electric drive rotates cross-shaped knives, which are made from a circular saw.

The main element of shredders are knives. The size of the finished mulch depends on their type and location. The cross-shaped fastening of the choppers allows you to obtain a finer fraction of grass or straw.

The knives rotate in a vertical plane, if a hole is made at the bottom, the processing process will be continuous

At the stage of drawing up the drawing, the engine power and the size of the shaft sleeve are taken into account. To make the right choice, pay attention to the rotation parameters:

a 1.5 kW device will cope with straw, small grass and branches up to 2 cm;
3-4 kW will allow you to make mulch from branches with a diameter of 4 cm;
motors from 6 kW are used on farms to process large amounts of waste.

If the master decides to build a gasoline grass shredder, choose an engine with a power of 5 kW
or more. Most often, circular or milling knives are used in designs. The discs shred damp grass and thin twigs. Milling knives can process brushwood up to 8 cm thick.

Milling-turbine types of knives chop even very thick fresh branches

Operating principle of the device

The design of the grass and extra branches shredder itself is quite simple. This will include several basic elements:

Protective cover.
A special working shaft, which is equipped with additional knives.
Engine.
Reception box.
Pulley with additional belt.
Metal frame.

To make it quite simple and comfortable to move such a device around the entire site, it should be placed on a specialized two-wheeled base. The operating principle of the device is considered quite simple. So, the shaft, with the help of a special motor and an additional belt or chains, begins the process of rotation. At this time, branches and excess grass enter the box, which are quickly chopped using sharp and small knives. In general, this resembles the operation of a simple meat grinder.

Such grass cutters are often used by summer residents themselves. In addition to all this, you can find industrial devices on sale that can easily cope with very thick branches. Of course, such devices are distinguished by a particularly complex design and increased productivity.

Grass cutting device

A weed chopper or grass cutter is a successful and irreplaceable device for a personal plot. There is an option to finely chop the cut grass or weeds and use them in compost as an insulation material for the winter. A grass grinder for chickens, as it is also called, and other poultry, is also very useful: finely chopped grass is even better suited for feeding. The device is capable of shredding a large volume of cut grass or weeds within a few seconds, which saves both time and physical effort of the owner.

A regular grass cutter consists of:

iron frame,
Working shaft with cutting knives,
Motor,
Boxes or funnels for receiving raw materials,
Pulley with belt,
cables,
Protective casing.

Garden grass cutters are lightweight, which makes them easy to move, compact, and have good performance.

You will prefer an electronic or petrol engine for the grass cutter.

The electronic version of the motor is the least noisy and more successful in operation; it is lightweight and can be turned on by simply turning the toggle switch. Disadvantages of the electronic motor: dependence of the device on the length of the wire and restrictions on the size of the thickness of the raw material.
The internal combustion engine allows you to use the device even where there is no electricity, it is more powerful, and is capable of crushing even tree branches. Disadvantages include its noise and relatively heavy weight.

Device Features

A wood chipper is a very convenient tool. However, not everyone can afford such a purchase, so most gardeners prefer homemade solutions. But is it possible to create a device without the appropriate plumbing and welding skills and tools? Unfortunately no. Even a simple branch chopper based on circular saws is created by following strict instructions. In addition, to create shafts and bearing housings, you need to turn to professional craftsmen. The whole process can be divided into the following stages:

Finding a suitable shredder design.
Selecting a power plant and calculating the final drive.
Selection of metal components and parts that need to be turned using a lathe.
Frame installation.
Installation of drive, cutting parts and belt drive.
Installation of the protective casing and hopper.

When creating, you should be guided by the following rules:

If the priority is to obtain small wood chips with minimal resources, give preference to models made from circular saws.
If you are going to chop small diameter branches into a larger fraction, a cutting mechanism such as a jointer is the ideal solution.
If you want to chop branches in large quantities, equip disk crushers.

If you have decided on the choice of wood chipping machine, start preparing parts, materials and equipment. However, before that, there are a few key tasks you need to complete.

Choosing an engine and belt drive - what is important to know about it

The efficiency of chopping branches depends on the rotation speed of the electric motor shaft. To ensure reliable crushing of wood, it is necessary to ensure that the cutting disc rotates at a speed of at least 1500 rpm. However, it is still necessary to take into account such an indicator as the amount of torque. This value is closely related to power, and the greater the value of the latter, the higher the force parameter.

How to achieve the required rotation speed of the crusher cutting disk if the electric motor reaches a speed of 2800 rpm? For this, a belt drive with pulleys of different diameters is used. To reduce the rotation speed of the electric motor shaft by 2 times, you need to install a pulley on the drive shaft with a diameter 2 times smaller than the size of the pulley on the driven shaft.

An important point in the design of a homemade shredder is the choice of transmission mechanism. The safest type of gearbox is a belt drive. Its advantage is that if the workpiece jams, the belt will slip along the pulley, eliminating the occurrence of negative consequences. This type of transmission mechanism is considered not only safer, but also reduces the likelihood of engine failure due to overheating and shaft jamming.

This is interesting! To reduce the rotation speed of the shredder cutting discs, you need to install a pulley with a diameter of 100 mm on the motor shaft, and a disk with a diameter of 200 mm on the shaft of the shredder.

Shredder design for branches and grass

The purpose of the unit is to quickly and safely grind plant debris. The main function is performed by the cutting block. The knives are driven by the engine directly or via a belt drive. The units are installed on a stable frame. The moving elements are covered with a casing. Two compartments are made for feeding branches and unloading chips.

Metal frame

A homemade shredder with a powerful electric or gasoline engine needs a stable, durable frame with space to install the engine and a rectangular support for the cutting unit.

To make the shredder frame use:

profile pipe 25;
corner at 30;
channel.

Engine

Full autonomy, work anywhere in the garden, independence from the outlet - the advantages of a gasoline engine. A homemade shredder for processing branches, tomato tops, and grass is equipped with a motor from a motor-cultivator or walk-behind tractor with a capacity of 6 liters. With. It is moved from one unit to another.

Electricity costs are lower than gasoline, so if there is a network on the site, an electric motor is installed on the unit. To chop branches 2-3 cm thick, a 3-phase electric motor of 2200-3500 W is sufficient. When making a low-power grass cutter, they take engines from household devices. They are removed from washing machines and vacuum cleaners.

The thickness of the branches processed by the shredder depends on the design of the cutting unit. In home-made designs, several options are implemented:

to grind branches with a diameter of 7-8 cm, several cutters are installed on the shaft;
hammer-type cutting block for grinding thin rods;
the universal cutting mechanism is made of 15-30 circular saws mounted on a shaft;
knives from factory garden equipment - brush cutters, lawn mowers;
chop grass - trimmer line;
stump crusher from a plane;
two shafts with 3-4 steel knives for cutting branches of bushes and trees.

How to make a grass grinder from a grinder with your own hands

To make your own grass chopper from an angle grinder, you will need a pipe with a diameter of 15 cm for removing the mulch, a metal profile 2 * 5 cm for the frame and a container with a capacity of 20 liters.

Manufacturing procedure:

Prepare the container. On one side at the bottom, a hole with a diameter of 15 cm is made so that it is possible to install an outlet for mulch. At a distance of 5 cm from the hole, a piece of 2*2 cm corner is attached. The length of the part is equal to the radius of the container. This is a grass limiter. He will not allow the finished mulch to remain in the bucket and will push it towards the exit. Knives are made from a circular saw blade. On one side they are rounded and sharpened.
The working knives are raised so that they do not fall in front of the limiter. A lid with a hole inside with a diameter of 15 cm is installed on top. This part will allow you to hold the grass, it will not jump out of the container under the influence of the engine.
A frame is welded from a metal profile 2*5 cm. The height is selected from personal preference, but not lower than 30 cm. The frame resembles a stool. On one side, a base for installing an angle grinder is attached to the legs. It is made of sheet steel 3 mm thick. Using self-tapping screws, secure the angle grinder to the base in a horizontal position, with the sleeve facing up.

For ease of use, the shredder is placed near the compost heap. The outlet casing is inserted into the opening of the composter and the production of mulch begins. The grinder is connected to electricity. Turn on the maximum operating mode and begin to pour grass, tops and branches into the receiving container.

To make the herb chopper last longer, the body is sealed with sheet iron over the container and painted.

Attention! To avoid injury, the receiver is made higher than the length of a person's arm. This way, when loading grass, there is no risk of accidentally hitting the knives and injuring yourself.

From the Bulgarian

A shredder made from an angle grinder (grinder) is a very simple and quick unit to manufacture. In order for the shredder to grind grass and branches up to 4 cm thick, a grinder with a power of more than 3 kW is needed as an engine.

To work you will need:

metal corners 35x35 mm;
metal sheet 3 mm thick;
any metal container (bucket or boiling water);
homemade or purchased plate knives (from a lawn mower);
fasteners (bolts, nuts, washers);
sheet metal;
electrodes, cutting and grinding discs for an angle grinder.
electric drill;
welding machine;
Bulgarian;
spanners or open-end wrenches.

Before starting to manufacture the unit, the corner is cut and a frame similar to a chair is welded. For safe operation of the installation, the base must be stable.

The work is carried out in the following order:

A grinder is attached to the welded frame, with the shaft up.
A hole 10 cm long and 5 cm wide is cut in the side of the container.
A box for removing the ground mass is made from tin and attached to the slot.
At the bottom of the container, a hole is drilled in the center for the grinder shaft.
The grinder is attached to the frame.
Place a blade knife or a disc from a lawn mower.

Drawing up a drawing

In order to avoid having to redo a partially assembled garden apparatus, it is necessary to correctly draw up a drawing, taking into account the size and shape of all available parts.

Numerous forums will help with this, where users discuss the most successful configurations and technical solutions.

In addition, they also share their experience of independently manufacturing garden waste and garbage shredders, posting not only drawings, but also photos and videos of their devices, and also leave feedback on their work.

When drawing up a diagram, you will be able to determine the location of mounting holes and welds. This will allow you to first make individual parts with pre-drilled holes, and then attach the corresponding units to them without adjustment.

Ready-made drawings can be found on the Internet, after which, based on them, you can make a new drawing with dimensions, which will take into account the features of the available parts and mechanisms.

The main advantage of this method is that it eliminates the need to independently determine and calculate the overall configuration of the finished device and the location of the main elements.

Here are drawings of some devices that can be used as basic ones:

Drawing 1 - This is a standard design for a stationary rotary chipper that works well as a garden chipper.
Drawing 2 - This is the design of one of the shafts of a two-roll shredder. With some modifications it can also be used in single shaft shredders.
Drawing 3 – Design of a two-roll shredder.
Drawing 4 – Drawing of a grass chopper with an electric motor, however, instead of an electric motor, you can install an angle grinder or a drill.

Main components of a garden shredder

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

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

According to the principle of operation, some homemade shredders are comparable to a meat grinder (they draw in and then grind organic matter), while others are comparable to a coffee grinder.

This will allow you to assemble the shredder one by one and thoroughly. The power of such a device will allow you to process huge volumes of cut grass. A shredder, specifically the name given to such home-made devices, can crush not only freshly cut grass, but also hay into small pieces, which is always vital in a farmer’s household.

Operating rules

When working with any electrical device, safety precautions must be observed. The grass cutter is no exception! To prevent the device from deteriorating, you need to know the basic operating rules:

The mechanism will jam if damp branches or grass are placed in the device.
You cannot store raw materials in large quantities. Everything should be in moderation.
The device must always be supervised when it is switched on.
The mechanism has piercing and cutting elements, so children should not be allowed near the device.
To prevent the device from getting wet in the rain, it is installed under a canopy.
Do not allow foreign objects such as glass or metal to get inside the device.
If something is stuck inside, the device is disconnected from the network and only then the stuck part is removed.
Electrical wires must be insulated.

The first launch of the device is done very carefully, since it is the most dangerous. https://www.youtube.com/embed/HoCh_HLO-Vc

How to assemble a cutting element yourself

To make a milling knife you will need:

circular saws (10-12 pcs.). Their quantity may differ from the indicated amount, both smaller and larger. The more disks are installed, the smaller the chips will be at the output;
threaded rod M20;
bearings (internal Ø 20 mm);
dense soft plastic for making spacer washers;
washers and nuts for fastening.

Assemble the knife as follows:

Place the disk on the pin (its diameter of 20 mm coincides with the hole of the saws).
A washer cut out of plastic should be installed between adjacent disks. It is necessary so that the cutting edges of adjacent saws (they are wider than the blade of the blade) do not cling to one another.
The outer disks are secured with washers and nuts. As a result, you will get a shaft with circular saw blades located on it. All that remains is to install the bar with saws on the frame using bearings, bushings and clamps.

What is it needed for?

It is known that the best fertilizer for the soil is given by nature itself. Fallen leaves, branches, grasses form a valuable litter that protects the surface from erosion and other adversities. They contain a large number of fibers, micro- and macroelements, all together this helps the earth to “give birth” well. But what does an ordinary gardener do? He weeds the grass in the beds down to bare ground, burns the tops and leaves, and uses chemical fertilizers to increase productivity. All this only depletes the soil, rather than helping it.

Experienced summer residents use cut green mass for mulching and composting.

Experienced summer residents know that the cut green mass must be returned back to the ground. We are talking about techniques such as mulching and composting. In the first case, plant organic matter is used to cover beds and tree trunks; in the second, it is used to prepare fertilizer. Both methods require preliminary processing of primary raw materials, which is what a garden shredder will help with (in Europe it is called a chipper or shredder).

Nikolai Kurdyumov, a famous permaculturologist, in one of his books talks like no one else about the benefits of compost for the soil. And to obtain it, he recommends using a garden crusher.

What a farmer will get from a shredder on his plot:

No piles of vegetation waste, clean area.
Always have mulching material and good fertilizer on hand.

Saving resources of time and effort that would have been spent in the absence of the device.
Solving the recycling problem.

A garden shredder is indispensable for composting, as it reduces the volume of the compost heap several times. Small wood chips and other vegetation are more quickly susceptible to biological decay, due to which the production of ready-made fertilizer is reduced to one season. Waste-free production is organized at the site - almost any rubbish goes into use. It is convenient to use the crusher in conjunction with a garden composter.
