How to make a grass chopper with your own hands?

A grass chopper is a very useful thing in housekeeping. It is able to process plant materials faster and more efficiently than manual work. For it to appear in the arsenal of accessories, you do not need to purchase a new device in the store.

A do-it-yourself grass chopper can be made from an old washing machine. The device will help with the farm and will process plants for composting or food for chickens as well as a device bought in the store.

This apparatus is of two types.

• Petrol. The work of the device does not depend on the power supply, therefore it can be used in any part of the site. It is recommended to use a gasoline shredder when handling large plants. The disadvantages of a gasoline grinder are its noisy operation and rather heavy weight.
• Electric. It is lightweight and compact, but the power of such a device will be less than that of a gasoline one. 1.5 kW will be enough to process a small amount of waste. If more labor-intensive work is expected, it should already be 4 kW. The motor, which has a power of 6 kW, is able to effectively chop even large plants and branches.

To create a shredder, you will need a number of tools, such as:

• drill;
• Bulgarian;
• hammer;
• screwdriver;
• pliers;
• fixing elements - washers, nuts and bolts.

You will also need to prepare the following items:

• a tank from a washing machine (it is desirable that it has a cylindrical shape);
• a frame that can be built from a metal corner;
• electric motor (required power - at least 180 W);
• on / off button;
• container for processed raw materials;
• wire and plug;
• knives.

Home installations use circular knives or hacksaw cutters. If we talk about specialized units, then 3 types of cutting elements are most often used in them:

• circular knife - processes grass and small branches;
• milling design - capable of chopping brushwood 8 millimeters thick;
• milling and turbine device - copes with large and wet branches.

Before starting work on the creation of the device, it is worth taking care of the drawings, which will help to follow the sequence of actions and prevent inaccuracies and errors.

Sequencing.

• Make a rectangular hole at the bottom of the tank. This is where the cutting elements will be fixed. It is optimal if they are higher than the hole itself. The approximate dimensions are 20x7 centimeters.
• The protective cover can now be made. To do this, you need to close the resulting hole with a metal sheet, and then fix it with bolts. This prevents shredded plants from scattering.
• Make a stand. The welding machine will help with this.Its height is selected depending on the container intended for collecting recycled materials. For comfortable transportation of the device, the stand is equipped with wheels.
• Prepare the motor and make the bushing on a lathe. In this case, the length of the sleeve must be at least 50 millimeters. Make holes on the shaft with a drill, then fix the bushing. Place the motor on the bottom of the tank, then secure it with the studs.
• Sharpen the cutting elements. For the processing of brushwood, it is necessary to sharpen one-sided, for grass - to make diamond-shaped plates. It is important to choose the right length of the knives - they should not come into contact with the walls of the device.
• Make holes in the middle of the knives, then fix them to the motor shaft with a nut.
• Connect the resulting structure to the stand by welding, then connect the power button, as well as the wire for connecting the power supply (if necessary).
• To protect the engine from bad weather conditions, it is necessary to make a cover. A sheet of metal is suitable for this.

To get started, connect the shredder to the power supply, then load the shredder material into it. It is not recommended to fill the entire tank immediately. Then you need to substitute a container for processed plants and turn on the device.

The grinder from the grinder can also process plants. Fresh grass processed with such a device is used as compost or mulch, while roots and grains are suitable for feeding birds or farm animals. Such grinders are often used to make herbal flour from nettle.

The device can be made independently at home. The scheme of the work does not imply anything complicated.

For the knives to function, the power of the grinder must be at least 1.5 kW. They are created from a saw blade. It is necessary to cut off unnecessary elements from it and leave only the cruciform part. In this case, the opposite cutting structures must be bent: the first pair of knives - up, and the second - down.

A welded casing is fixed on the grinder. An outlet should be located on its side. After that, it is necessary to put on a polypropylene bucket on the casing; instead, a strong container is also used, which remains after using water-based paint.

To grind the raw material, it is necessary to fill a bucket with it, and then close it with a lid. A bag is attached to the outlet, into which the processed mass will fall. After that, you need to turn on the grinder. The action can be made continuous: for this you need to make holes in the lid and gradually add raw materials for processing.

The shredder will help to significantly reduce the time that would be spent on manual work. There are different ways to make this simple but useful device yourself.

For example, you can build it from a drill. To do this, a little grass is poured onto the bottom of the container, after which a drill is started, on which a homemade knife is pre-planted. After a couple of minutes, you need to pour out the already processed mass. To make a device from an electric drill, you must adhere to the following manufacturing scheme:

• a knife is made from a metal strip, after which a hole is drilled in its middle;
• the cutting element is put on a metal rod, the end of which is fixed on the head of the electric drill;
• a nut is screwed on the other end of the rod, which firmly holds the knife.

The shredder can also be made from a vacuum cleaner. True, not every model is suitable for these purposes. For example, the plastic base of the Typhoon vacuum cleaner can serve as a hopper for a device. It has a principle of operation similar to others, but at the same time it differs in greater productivity.

• With the help of a lathe, it is necessary to grind a bushing, which is placed in the lower part of the hopper, pre-made knives are attached to it. The material for shredding is fed from the top, and the recycled material leaves through an opening on the side of the device.
• A protective cover is put on the device.
• The device is stationary and fixed on a metal frame. The main thing is that the base has sufficient stability, otherwise the safety of the engine may be impaired. The device is bolted to a metal stand.

You can build a grinder for a summer residence from a gas cylinder, instead of which a regular bucket made of durable material is often used.

• You need to make a couple of parts from the balloon, cut off the bottom at one half, and then make cuts along its entire surface. They should be staggered and about 10 millimeters wide. The punch will help you shape the holes to the desired shape.
• Steel strips must be attached to the edges of the cylinder with rivets. After that, it is necessary to weld 2 more on them, having previously made holes in them about 10 millimeters in diameter.
• Then you need to make curved handles and attach the housing with bearings to the flat part of the gas cylinder.
• The last step in the process is the construction of the stand. It is recommended to make it from wood material. For example, a table is perfect for these purposes - containers for non-processed raw materials will be placed on it. A container for already processed grass, forage or leaves should also be placed at the bottom of the shredder. It can be made from the rest of the gas cylinder.

The attachment can also be made from a trimmer. There are old trimmers in many garden areas, but with this method of manufacturing, the device will not work from top to bottom, but vice versa. The chopper can be built from both an electric device and a petrol cutter.

Many use the simplest method, including a mower and pushing the raw material under the rotating blades. At the end of the process, it is necessary to move the container for recycled raw materials by tilting it towards the apparatus. All vegetation is crushed in a matter of minutes.

Knowing the approximate algorithm for performing the work, you can make a chopper from various improvised means.
