Farmers are gradually moving away from manual labor. Owners of small private farmsteads are actively introducing small-scale mechanization tools to increase labor productivity. These tools include a straw chopper. Similar factory-made devices are commercially available, but it is not always advisable to purchase them due to their high cost. The fact is that the device of the chopper is extremely simple, and you can make it yourself.

Working principle and standard model

Explanations about the purpose of the chopper are unnecessary for those farmers who keep livestock. In addition, the device can be used to produce fuel briquettes from hay or straw at home.

Manually chopping the required amount of material for livestock feed is an extremely labor-intensive activity in terms of time and effort. And you shouldn’t even think about producing fuel briquettes in this way.

Some masters make artisanal shredders from a minimal set of available materials. Usually, old vacuum cleaners or pumps with a working electric motor are used.

Products of this type are easy to manufacture, but their productivity is extremely low. It’s only enough to feed ten rabbits. A large farm requires more raw materials.

As a result, you need a reliable straw chopper for private farmsteads, which you can do yourself. The power should also be at a level that will allow the device to operate for up to several hours without stopping.

Description of typical design

A typical design involves the elements from which the device is made. Their minimum set can be supplemented with auxiliary ones. The goal is to improve the comfort of working with the device.

Standard chopper set:

• The bunker is a container of sufficient volume. Usually they take an old barrel or a large can into which the processed vegetation is placed.
• The electric motor is installed at the bottom of the bunker. The main thing is that its power is sufficient to work non-stop and for heavy loads.
• An axis on which 3 to 6 knives are attached. It is attached directly to the axis of the electric motor.

The basis of the apparatus is a hopper with sharp knives, which are rigidly fixed to a steel disk. The disk is mounted on an axis, which is the shaft of the electric motor or is connected to it through a gearbox.

A bunker is a container for storing material - hay or straw, which requires chopping. The cutting process takes place in it. For safety reasons, the bunker is made as high as possible so that when loading raw materials your hands do not touch the knives. The shape of the container is usually cylindrical, but you can find the shape of an inverted cone. Place the container on a stand, usually in the form of a tripod. The height of the stand is such that an electric motor can be installed below. The latter is fixed to the bottom.

Sometimes the bunker is made small in height, but with a lid for safety reasons. The lid must have a hole for loading raw materials.

Production on a continuous basis is created by installing a waste dump. Through the device, the crushed material is thrown out of the hopper. This allows raw materials to be added continuously. That is, there is no need to stop the engine to remove the chaff and add raw materials. This results in significant time savings. It will be made from the bottom of the bunker. The shape is not important, the main thing is that there is a slope for dumping the material.

A disk with knives placed on it is an extremely difficult part to manufacture. The design can be arbitrary. The goal during assembly is to achieve maximum balance so that the device does not shake from vibrations during operation.

Scheme of work

The container is usually a plastic barrel. It is advisable to cover it with a lid and make a hole on the side so that the chaff does not fly away in all directions. The operator just has to supply the raw material and empty the container with the chaff in time. Ideally, several of them are used, changing as they are filled.

Materials and manufacturing process

The manufacture of a house shredder begins with a drawing on paper. This allows you to have a visual representation of the design and identify shortcomings or refine important nuances at the design stage. Remaking the finished product will be more expensive, and unnecessary time will be spent.

Assembly materials:

The electric motor is the main part of the device, which specifies its characteristics. The motor is selected depending on the volume of the straw chopper hopper. The greater the mass of raw materials per load, the more powerful the engine required. Typically, an electric motor with a power of 2.2 to 6 kW is installed on a hay and straw chopper for private farmsteads. The speed of rotation should not exceed 2 thousand/min for safety reasons. Optimal - 1.5 thousand/min.

An electric motor with a rotation speed higher than optimal can also be adapted for installation in a structure, but it is not directly connected to the shaft. For this use a reduction gear, often belt. You can use a gear drive. The reduction gear allows you to increase the output of the motor and chop root crops and even small branches.

The motor is connected to the shaft, on which the disk with knives will be installed. A tube can act as a shaft, but only straight, without distortions. This is necessary for proper balance, otherwise vibration will occur, which is unacceptable.

The knives are installed on the shaft so that there is a minimum distance between them and the counter blades. This will ensure high-quality grinding of raw materials.

Assembling the device

It is necessary to assemble with high quality, adjusting the parts. The service life and safety of a household straw chopper depends on the quality of the assembly. The device contains moving parts and loose connections may come loose during operation. This could result in injury to the operator.

Assembly order:

1. They work with the container and install an electric motor on it. If there is no bottom in the bunker, it is welded. A bracket and a metal plate are installed below, where the electric motor is attached. The plate is secured with a tank, and the engine is attached to it.
2. Inclined supports are installed above the motor, which will serve as a bracket for installing the unloading device. It is mounted in the place where the supports connect to the edge of the bunker.
3. Attach the motor with self-tapping screws or bolts. The motor axis must be located above the inclined supports.
4. The cutting tool is formed. For this, pieces of high-quality carbon steel, which can be taken from the waste blade of a metal-cutting machine, are suitable. The disk is taken in such a size that the knives installed on it do not touch the walls of the hopper.
5. A disk with knives is attached to the vertical axis. The axle can be made from durable steel pipe. The main requirement is that the pipe be smooth, without bends, as they will provoke vibration, which will affect the reliability of the device and its safety. The axis with knives is installed on the motor shaft.
6. Install a lid on the hopper, which will increase the safety of the device.

The finished product is placed on a stand, which is fixed to the floor. It is advisable to paint a homemade straw chopper. This will prevent corrosion and the device will last a long time.

Hay from a home-made crusher is in no way inferior in quality to products from a factory-made device. All that is required is monitor the condition of the knives. The power of a homemade machine is sufficient not only for making chaff from hay or straw, but also for chopping fresh grass. Such food is beneficial for livestock because it is easier for them to chew. Dry straw can be used to make fuel briquettes for personal use and for sale. This will pay for the device.

Working on the machine yourself, even taking into account a new motor, will be cheaper than purchasing a ready-made one in a store. The market is flooded with Chinese products, the quality of which is questionable. Shredders from European manufacturers are expensive and not suitable for small farms.

Straw choppers can be useful on the farm, especially if you are involved in breeding and keeping livestock. You can make such a design yourself, but you can also purchase it in a store. However, the first option will undoubtedly cost much less.

Methods for making a chopper

You can make the described equipment yourself in several ways. After reviewing them, you can choose the one that is most suitable for you. Drawings of a straw chopper will help you make your choice. So, the first option for manufacturing a chopper involves using a drill. The grinding process will resemble the operation of a food processor. Here, too, you will need a cylindrical body, which serves as a simple bucket in which a well-sharpened knife is located. If you run it in a circle at a significant speed, the straw will be cut. In order to make such a unit, you should use a dual-mode drill of the Temp brand, the power of which is 850 Watts. The knife must be made of hacksaw blade. The secret lies in sharpening the knife. If these manipulations are performed correctly, the straw will not get tangled in the blade.

Such straw choppers must be made by sharpening the knife on one side. It must be positioned with the sharpened surface down.

Making a shredder from a vacuum cleaner

If there is no drill available that could be used to make the device, then you can use a Typhoon brand vacuum cleaner. According to the operating principle, this device will not differ from the previous one, but it will look more attractive, in addition, the productivity of the unit will be much greater. If in the above case the straw is in a bucket where the cutting blade is placed, then now the raw material must be fed through the upper hole, while the finished substrate will exit through the lower hole, which is located in the side of the vacuum cleaner. A do-it-yourself hay and straw chopper must be made in such a way that it is possible to correct the situation in which the straw begins to be scattered. This can be done by using a protective casing. Of course, such an installation does not look as impressive compared to a purchased one, but it works perfectly and does not cost anything.

Straw choppers at home can be made using the same principle, but using any container. You just need to choose one that has a cylindrical shape. It could even be an old pan or a piece of pipe of suitable diameter. The unit can be equipped with a motor. You need to use one that has a power of 180 watts. It is acceptable to borrow one from a washing machine that is no longer in use. To make knives, you can use an old hacksaw blade, and as stands you can prepare a rectangular profile, the dimensions of which are 15 x 15 mm.

Fastening the components of the unit

When making straw choppers, it is also necessary to prepare a bushing, which must have a height equivalent to 40 mm. It is necessary to fix knives on this element. The bushing can be prepared at

The engine, from which the pulley must first be removed, should be fixed to the container on studs, located at the bottom. In order to fix the knives, it is necessary to use water nuts, the diameter of which is 32 mm. During the manufacturing process of bushings, it is necessary to cut threads in advance to install nuts. We should not forget about the hole for the motor shaft.

To ensure a strong fastening to the shaft, 2 holes should be made in the bushing, the diameter of which is 7 mm. You will then have to cut an M8 thread into them, which will allow you to install locking bolts. On the reverse side of the motor shaft, it is necessary to machine the pads to increase the strength of the bushing with bolts. Having retreated 15 mm from the top of the cylinder, it is necessary to remove the edges using a grinder for this, this will allow you to form a square, the side of which should be equal to 25 mm. It is supposed to put knives on him.

Knife making

A straw chopper has its main component - knives. They can be made from a hacksaw blade, from which four blanks are cut using a grinder. In the central part of each element, a square hole should be prepared, the side of which should be equal to 26 mm. The rigidity of the original fabric will affect the width of the parts. The knives must be positioned closer to the bottom. In order to sharpen the cutting edges well, you need to use a sharpener. The bolts that hold the bushing must be located above the blades. If it is not possible to make a hole for chopped straw, placing it under the knives, it should be made from the side. Why does a grinder come into play, which can be used to make a circle of 7 x 7.

When making a straw chopper, it is necessary to form a guide element of the body; for this, steel is used. The housing must be secured to the chopper with M3 bolts. Care must be taken to ensure that the installation platform is as stable as possible. Why does its base need to be made larger compared to the top part. It must be made as functional as possible, in addition, it must be comfortable. A hay and straw chopper must have a platform that will not only support the installation, but also protect the motor. It must be fixed to the container using three M6x45 bolts. But it is preferable to cover the side edges of the platform with sheets of steel. In the racks, you need to prepare threads for installing M3 bolts, which secure the blades to the platform body.

Making a chopper from a pump

A hay and straw chopper can be made from scrap materials. In order to perform the simplest unit, you can use an Agidel brand pump; by the way, any similar electric motor will do, but you need to choose one that will be capable of delivering about 3000 rpm. In addition, it must be powered from a 220 V network. You will also need an old aluminum pan. A hacksaw designed for woodworking will also come in handy. It will be needed in quantities of several pieces, and will be needed for making knives.

When you make a straw chopper with your own hands, you need to think about how the installation will be started; for this, a button will be useful, which will be a night vision device from an old washing machine; also prepare a plug and power cord.

A do-it-yourself straw chopper should be made in such a way that the motor is located under the pan. While the start button should be located at the rear of the platform, this will allow it to be easily reached.

Safety regulations

A do-it-yourself straw chopper, the drawings of which are presented in the article, must be used extremely carefully during operation, because the design is based on sharp knives, which are considered quite dangerous, as they can cause serious damage to a person.

If you have made a device that runs on electricity, then special care must be taken so that the shredder will serve for a long time and will not cause injury. Particular care must be taken to ensure that children do not try to use the device, as this can lead to unpleasant consequences. A do-it-yourself straw chopper, the drawings of which must be reviewed before starting work, must be used only for its intended purpose.

Any farmer's household should have a variety of equipment that makes it easier to care for animals and grow plants.

A straw chopper is one type of such equipment. Such a unit can save time and effort during agricultural work.

1 Application

This technique mulches straw for further use in agriculture. Chopping hay and straw is necessary for:

• production of feed for animals and birds;
• flooring in the stable;
• for cooking;
• production of fuel briquettes;
• laying the ground under the strawberries.

For work on the field, it is more productive to use a hay roll chopper. With it you can cultivate several hectares of land in one trip. This way you can save fuel.

A private home always involves a lot of housekeeping work. You can buy a chopper in a store or make such a unit yourself. An industrial device has advantages over homemade ones, but the price differs greatly.

1.1 Variety of purchased equipment

The equipment produced at enterprises can be of different sizes and differ in power. A popular model is the M15 straw chopper. This unit has a convenient bunker for filling hay or and has the following characteristics:

• operates from a network of 220380V;
• The drum with knives makes 1500 revolutions per minute;
• 3 kW – power;
• Weight 130 kg.

These options allow use a hay and straw chopper on small farms and in private households in the presence of poultry and livestock for the production of roughage and processed into flour.

Numerous positive reviews can be found about the KR02 straw and hay chopper.

This model is compact with good performance. It has high characteristics:

• engine power 1.54.0 kW;
• network 220380 V;
• weight 65 kg;
• productivity 25 kg/hour.

Such equipment takes up little space in the yard and consumes little electricity. It is capable of supplying an entire farm complex with chopped hay.

2 How to make a unit with your own hands using a drill?

If the owner is a little versed in technology, then he can do it. Such a do-it-yourself hay chopper will cost several times less than a purchased one, but you will have to put a little effort into assembling it.

The first type of hay and straw chopper can be constructed with your own hands based on a drill.

The principle of its operation will be similar to the operation of a food processor. The body can be an iron bucket. Well-sharpened knives are attached to a dual-mode drill. When turned on, the drill wraps around the blades and they grind the straw.

Such a device will be able to chop small batches of straw. This amount is enough for. The knives should be sharpened only at the bottom, then the hay will not get tangled around them.

2.1 How to make a unit from a vacuum cleaner?

2.2 Features of the manufacture of knives and the entire structure as a whole

The main part of the equipment are knives. They must be made of a special material - hacksaw blade. Using a grinder, the required number of blanks is cut, most often four of them are needed.

In each part, a square hole with sides of 26 mm is cut in the center. The width of the blanks depends on the rigidity of the material itself. A high-quality sharpener is used for sharpening. The knives are placed at the bottom of the tank. The outlet for chopped straw is designed at the bottom or side. A round hole can be made in a metal case using a grinder.

The design of the support on which the chopper will be mounted is carefully thought out. In order for the unit to be stable, it is necessary to make the base of the support larger in size than the device itself.

The chopper is attached to the support using bolts. Thus, the installation will not vibrate much during operation, and the hay will not fly away. And the platform on the base will protect the engine. Manual loading of hay should not be dangerous for the owner.

Therefore, the wrapping mechanism must be deep inside the container so that it is not directly accessible.

2.3 Pump unit

If the household does not have the required drill or a suitable model of vacuum cleaner, you can use a pump of a certain power and model. Most often, the Agidel brand or another pump with a power of at least 3000 rpm and a 220V network is used.

This design will require a large aluminum pan and a hacksaw for working with wood. You will need several of these tools. They are indispensable for making chopper knives.

To start the unit, you need a button. It can be removed from a failed night vision device or an automatic washing machine. The starting system requires an electrical cord and plug. The motor is located under the pan. And the trigger mechanism is located at the back of the platform.

To keep your shredder working long and productively, need to be constructed only according to pre-prepared drawings. They will help prevent mistakes when assembling the unit.

How nice it is to stroll through your own garden, along its beautiful paths, admire the well-groomed beds and flower beds, and then eat a rosy apple straight from the branch. But in order for all this splendor to exist, a lot of work has to be done. In order for the soil to be fertile, it is necessary to add a lot of organic matter. Mulching with grass is a great way to keep the soil in good condition. It can be spread out on the beds immediately after mowing or pre-composted. In order for thick stems of greenery to decompose more actively, it is recommended to chop them first. You can make your own herb grinder or just buy one.

The choice of finished equipment largely depends on the volume of raw materials to be ground. After all, ground grass is needed not only to fertilize the soil. It is also useful for those who have a subsidiary farm: chopped greens are added to the feed of livestock and poultry. A small amount of work can be easily handled with a regular saw. This is the name given to a triangular plate equipped with a durable and sharply sharpened lower edge.

A chopper is a basic tool for chopping grass. If the amount of work is small, then you don’t have to buy or build a gasoline or electric grass cutter. Place the cutting on the cutting and get to work

To work, the chaff is placed on a long stalk. It allows you to avoid bending over while doing work. The raw material to be chopped must be spread on the ground in a layer of 10-15 cm. The surface should not be hard, and the layer of grass should not be too large. Then the cut will not become dull and will not spring back. When the chopper hits from top to bottom, the grass is cut into small pieces.

If the volume of greenery being processed is large enough, you need a solid unit, which this video will help you choose.

The main purpose of this article is to find ways to independently manufacture the equipment that will be needed on the farm. If you have the desire, patience and minimal skills, you can make a homemade herb grinder that will work just as well, and perhaps even better, than a store-bought one. Better, because only you yourself know the needs of your farm and can perfectly adapt the device to your own needs. It will be exactly what you need!

Option #1 – a drill to help you!

An excellent grass cutter can be very easily built from a regular drill. Exactly how this simple device works can be seen in the video below.

So, the grinding process resembles the work of a food processor: in a cylindrical body, the role of which is played by a simple bucket, there is a sharply sharpened knife. When it rotates in a circle at high speed, the grass is cut. To make this grass cutter, a two-mode Temp drill with a power of 850 watts is used. The knife is made of hacksaw blade. The whole secret is hidden in sharpening the knife. If done correctly, the grass will not wrap around the blade. The knife should remain clean and free of greens.

Sharpen the knife with a one-sided sharpening. It should be oriented with the sharpened plane facing down. If you have to chop fresh grass, the best shape of the knife would be a narrow diamond so that the cutting edge disappears at an angle to the edges. As a last resort, you can round the blade towards the tip. Then the grass, which is affected by centrifugal force, slides along the cutting edge of the knife straight to the edges. It cuts easily and never wraps around the knife.

Option #2 – for owners of the Typhoon vacuum cleaner

The working principle of this device is no different from the previous one. It just looks more civilized and its performance is higher. If in the previous case the grass was already in the container where the cutting tool was placed, now the raw material is supplied through the upper hole, and the finished substrate comes out through the lower one, located in the side of the apparatus. To prevent the finished silage from being scattered when spilled, you need to use a protective cover for the outlet.

Perhaps such a grass cutter does not look as presentable as a purchased one, but it is functional and practically free. Decide what is more important to you

The chopped grass is collected in a bucket, which must be carefully placed under the outlet. It is clear that when choosing the height of the racks for the unit, it should be taken into account that a bucket of normal parameters must pass freely in order to place it in the right place. So what does Typhoon have to do with it? The body from the old Soviet Typhoon vacuum cleaner is ideal for a basic garden grass shredder: it has an upper hole of the most suitable size. I repeat once again: this is an ideal option. But not the only one!

Any cylindrical container, be it an old pan, bucket or piece of pipe, will also work. The 180-watt motor can be borrowed from an old washing machine. An old hacksaw blade will be used for the knives, and it is recommended to use a 15x15 mm rectangular profile as stands. The bushing, 40 mm high, on which the knives will be attached, will have to be turned on a lathe.

The process of making a herb grinder is not as complicated as it seems. In the photo: No. 1 - the body, very convenient, because you can load grass into it from above, No. 2 - the motor from the washing machine, No. 3 - the location and appearance of the knives

The engine with the pulley removed is mounted on studs from below to the container. To tighten the knives, water nuts 32 mm in diameter are useful. When making bushings, be careful to cut threads for these nuts. Don't forget about the hole for the motor shaft. To ensure reliable fixation on the shaft, two holes of 7 mm in diameter are made in the bushing with M8 threads cut into them for locking bolts. Pads are machined on the reverse side of the motor shaft to increase the reliability of the bushing being secured with locking bolts.

At a height of 15 mm in the upper part of the cylinder, the edges were removed with a grinder to form a square with a side of 25 mm. Knives will be put on him. To make knives, you need to cut 4 blanks from a hacksaw blade using a grinder. A square hole with a side of 26 mm is cut out in the central part of each workpiece. The width of each part depends on the degree of rigidity of the original metal. It is clear that the knives should be placed closer to the bottom. Their cutting edges are sharpened using a sharpener. The bolts securing the sleeve are placed above the knives.

In the photo: No. 4 is a bushing for securing the knives and connecting the engine to the body, No. 5 is a square on which the knives will subsequently be attached, No. 6 is the chopper platform, which is made in the form of a truncated pyramid

If it is not possible to make an outlet for the silo directly under the knives, then it will be equipped on the side. To do this, you can use a grinder to make a 7x7 circle. Tin is used to form the guide body. The housing is attached to the chopper with M3 bolts. The platform of the unit must be as stable as possible. To do this, its base is made larger than the top. It has to be made as functional and convenient as possible.

The purpose of the platform is not only to support the chopper, but also to protect the engine. It is secured to the container with 3 M 6x45 bolts. It is better to cover the side edges of the platform with sheets of tin. The racks are threaded for M3 bolts, with which the sheets are secured to the platform.

Option #3 – grass cutter from what was on hand

Armed with the knowledge gained from reading the description of the manufacturing process of the previous unit, you can build yourself something equally simple and useful without much difficulty or effort.

This grass cutter is literally made from something you found in the shed. All things have served their purpose long ago, but in this design they will certainly be useful to their owner for a long time

For basic grass cutting you will need:

• Agidel pump or any similar electric motor capable of 3000 rpm and powered from a 220V network;
• old aluminum pan;
• used wood hacksaws, from which you can make wonderful knives;
• to start the engine you need a button, the role of which will be perfectly played by the NVD from the washing machine;
• plug and power cord.

We invite you to carefully examine the photographs, because they do not need any special comments. Everything is very clear. Start creating your herb grinder and you'll do great.

Pay attention to how the blades are placed in this herb chopper. It is possible that you will choose this particular model

The motor is installed under the pan, and the start button is located at the rear of the platform to make it easier to reach.

Such grass, chopped using a grass cutter, is perfect for feeding livestock and poultry, as well as for mulching purposes.

Option #4 – homemade straw cutter

Three previous units successfully turned grass into silage. But if we need a chopper not only for grass, but also for hay, it’s worth taking a closer look at another invention, which is presented in great detail in the video below.

A Few Safety Warnings

Any device, the creation of which is described above, is equipped with sharp cutting parts. To ensure that it serves you for a long time, brings relief in your work, and does not cause injury, follow basic safety precautions when performing work.

If the operation of the unit involves electricity, be doubly careful and take the necessary measures. Be especially careful that children do not try to operate the grass cutter. It's better to overdo it than to underdo it!

A straw cutter often becomes a reliable assistant for the owner of a large farm. Today there is a large selection of units that differ in size and shape. Below we will look at what parts a hay and straw chopper consists of, and how to make such a unit with your own hands.

Hay chopper - equipment design

All straw crushers have a similar design and consist of the same elements. The difference between them is only in size and shape. Let's look at the device using the KR 02 model as an example. The design of this household unit includes:

• The electric motor is the main part that powers the entire structure. The characteristics of the motor directly depend on the purpose of the crusher. For industrial purposes, large, powerful motors are used, while for domestic purposes, a medium and low power motor is well suited. The main thing is that the engine speed does not exceed 2 thousand rpm;
• Bunker for supplying hay and straw. The dimensions of the hopper also depend on the applications of the shredder;
• Metal plate to accommodate the motor;
• The bracket for mounting the motor is a part that holds the motor and absorbs its vibration;
• The supports for installing the chopper on the workplace are a kind of tripod that should hold the structure motionless;
• Knives and shaft are parts for directly cutting straw and hay;
• Unloading mechanism - this element has the form of a side pipe, which is attached to the structure body for supplying processed raw materials.

Both industrial and household straw roll shredders are equipped with a separate hopper, which contains chaff and other waste.

All hay crushers work on the same principle. To begin, the device is connected to the mains. After this, raw materials are supplied to the loading hopper, which, falling on the knives, are crushed, and enter the receiving hopper. All unground hay exits through the side hole into the waste container.

Tools and procedure for assembling a homemade chopper

Before constructing a straw cutter, you must carefully read the design drawings. With the help of a correctly drawn up diagram, you can figure out the dimensions of the parts and the location of their installation.

All metal components of the device must be made of sheet steel with a diameter of no more than 3 mm. To make the bracket, thicker metal should be used. Other parts of straw cutters for private farmsteads should be used:

• The electric motor can be taken from any household appliance;
• 200-liter iron barrel, which will act as a loading hopper;
• Several metal sheets welded into one area, at least 3 mm thick;
• 3 metal pipes, 2.5 cm in diameter - they will serve as support for the structure;
• Food processor knives that will need sharpening;
• Shaft - taken from any unnecessary equipment. The main thing is that it is smooth and properly balanced. Otherwise, the structure will vibrate and shake violently.

As an unloading device, you can use a plastic pipe that will be attached to the side of the barrel for loading. In this case, one hole is made in both the barrel and the pipe. The pipe must be installed so that its hole coincides with the hole in the barrel.

To make a hay grinder into flour, you will need certain tools:

• Sander;
• Drill;
• Welding apparatus;
• Standard set for metalwork.

Having prepared everything you need, you can make a straw cutter without any problems. Unlike a simple manual design, it will require a minimum of effort from you, and will process raw materials much faster and more efficiently.

How to make a straw cutter with your own hands - detailed description

The working unit of the product is a container welded from metal, inside of which a disk with sharp knives is installed. The disk itself must be securely fastened to the shaft of the electric motor. The bottom is welded to the body of the device, which also acts as a loading container, and a bracket is installed below it.

Metal supports are attached to the bracket, which can be equipped with gussets that will give the supports the necessary rigidity. Next, you will need to weld the unloading mechanism to the body.

The electric motor is mounted to a steel plate using self-tapping screws and bolts. This way, your homemade hay chopper will produce minimal vibration. A disk with welded knives must be mounted on the motor axis.
