Do-it-yourself grass cutter from a grinder and boiling water

What is abundant in any garden are weeds. The grass is pulled out, mowed, and it grows again. It is unwise to throw it away; greens are perfect for compost.

But before planting, the plants should be chopped. Using your hands is time-consuming and difficult; it’s easier to work with a grass cutter. Let's look at the process of building a grass grinder from an old washing machine with your own hands.

How the device works

Essentially, a grass cutter is a large blender equipped with knives. The chopper is constructed from a motor, connecting wiring, a container for grass and collecting raw materials, a shaft, knives and a frame.

The popular bookmaker has released a mobile application for Android, you can follow the link absolutely free.

In order not to carry the grass to the machine, but to work “on the spot,” the grass cutter is placed on wheels.

Operating principle: the engine transmits rotation to a shaft with knives that chop the grass. The raw materials are transported to a container for chopped greens, from where the mass is removed into compost pits.

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.

Tools and materials for making grass cutters

The master will need:

grinder or angle grinder;
drill with a set of drills;
welding machine;
winding testing device;
Screwdriver Set;
hammer;
bolts with nuts and washers;
a set of open-end wrenches or pliers;
washing machine tank;
motor with a power of 180 W;
knives;
electrical cable and plug;
container for collecting cut raw materials;
metal sheet for the casing;
metal corners;
control buttons (on/off).

When performing work, the master will not be hindered by personal protective equipment.

Garden shredder from washing machine

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

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

Tools you will need:

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

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

A shredder from a washing machine is made like this.

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

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

The start button will come from a converted washing machine. You just need to make sure to connect the extension cord of sufficient length.

Preparation stages

The main point is the choice of engine. Minimum power 180 W. If you have an old washing machine at home with a 1.5 kW motor, a ready-made grass cutter can cope with branches up to 2 cm thick. This motor is enough for cutting greenery with a large margin.

Knives are selected depending on the size of the cut. For example, disc blades cut greens and branches. This is convenient if you need to clear the area not only of weeds, but also of young maple, raspberry, etc.

Homemade grass grinder from a grinder

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

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

Tools you will need:

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

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

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

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

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

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

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

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

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

Making a Herb Grinder

The technology is like this:

The motor shaft is drilled with a drill. The diameter of a pair of holes is approximately 7 mm.
A sleeve with a length of 50 mm is put on the shaft. It is taken with a thread at one end and holes at the other. The part is ordered from a turner.
Align the holes on the bushing with the holes on the shaft and secure with mounting bolts.
The engine is fixed to the bottom of the tank. Fasten with studs or long bolts.
The tank is cut to height using a grinder. The height level of the walls is chosen according to the height of the user - whichever is more convenient for him.
The engine is not tightened tightly, only baited. This is necessary to determine the location of the outlet hole on the wall of the tank. After constructing the hole, the assembly is completed to completion.
The knives are put on the sleeve and secured with a nut. Install them so that they do not touch the walls of the tank.
A hole is cut along the bottom edge of the container to release the cut raw materials. The hole is located below the knives.
A casing is made from a metal plate that will prevent the grass from flying away during the cutting process. The casing is bolted to the body, and a frame is welded from the corners for mounting the tank.
The container is secured to the frame by welding. Connect the engine using a tester. The outputs of the starting and working windings are determined, the resistance mode is set and the windings are compared - the starting winding has more.

They connect it like this - the wire from the start is connected to the end of the start winding, the second end of the start winding is connected to the cable and the working type winding. The remaining end of the working winding is connected to the cable and wire from the start button.

It is extremely important to adhere to safety precautions during the manufacturing process of the device and when working with it. If foreign objects get into the range of action of the knives, the device will fail.

Operating principle and device of the grass cutter

If we compare grass shredders with other agricultural equipment, they are quite popular among gardeners. A wide range of products allows both professionals and amateurs to purchase equipment according to their needs and financial capabilities. The range includes compact household appliances and professional equipment designed for processing raw materials in large quantities. A simple grass cutter includes:

Working shaft with cutting knives.
Container for raw materials.
Protective shell.
Electric or gasoline motor, cable and pulley with belt.
Steel frame.

The device works on a simple principle: the raw material is placed in a container with knives, where it is ground into a crushed mass. The operation of the device is similar to a working food processor. The volume of raw materials becomes smaller, which makes it possible to add it to the feed mixture or use it for mulch. For small volumes, raw materials are loaded into the container manually.

Herb grinder from washing machine

Adhering to design features , you can make a grass cutter from a washing machine with your own hands. For assembly you will need:

180 Watt tank and motor. There is such a motor in a washing machine. In order for the device to be able to process not only grass, but also large branches, a powerful engine is needed. The greater its power, the better.
Disc knife.
Electrical cable with plug.
Start button.
Container for raw materials.
Steel corner.
Connecting elements: bolts, bushings and washers.

A gasoline engine has more power than a washing machine engine. By installing it in the device, you will get a “three in one” device that, together with grass and straw, can process branches over 5 mm thick.

Assembling the apparatus

First, we assemble the upper container for processing raw materials. For this:

We take and cut the body of the washing machine to height. This will create additional convenience when operating the equipment.
In the lower part of the body, at the same level with the legs or slightly higher, we make a hole (20x7 cm) of a rectangular shape.
To prevent the grass from scattering in different directions, the hole is covered with a casing. The casing is made of a metal plate and secured with bolts.
Then prepare the stand. Here you will need a welding machine and a metal corner. Depending on the size of the container in which the raw materials will be located, the height of the stand is calculated. A tall support is made for a bucket; a low stand is suitable for a basin.
Two holes with a diameter of 7 mm are made on the motor shaft. They order from a turner or make on a lathe a bushing about 50 mm long, which is put on the motor shaft. The finished part is secured with studs on the underside of the tank.
The cut and sharpened knives are put on the shaft so that they do not touch the walls of the container. The knives are securely fixed with plumbing nuts (32 mm).
A welding machine is used to weld the container with the motor to the stand.
The tester determines the starting and operating windings of the motor . Less resistance indicates that this is a working winding. Having correctly identified the contacts, the motor is connected to the electrical cable.
The connection is made as follows: on the one hand, the starting winding is connected to the starting button wiring, and on the other hand, it is connected to the working winding and cable. The second side of the working winding is connected to the start button and cable.

After connection, the stand for the device is additionally sheathed with steel sheet. This homemade DIY herb grinder from the washing machine is ready to go.

Other manufacturing options

For a small amount of work, a hand tool - a chopper - is suitable. The main part of the instrument is similar to a triangle. Alloy steel is used for its manufacture. How convenient and accurate the work will be depends on the sharpness of the blade. Therefore, before starting work, the lower edge is sharpened. Cutting grass will become much easier if the tool is equipped with a long handle that will prevent you from constantly bending over. A thin layer of grass and branches is laid on a soft surface and chopped. To prevent the sharpening from becoming dull, you should not cut on hard surfaces.

Drill grass cutter

The design of a simple dual-mode electric drill is intended for a small amount of work. But despite this, the drill will make a good grass chopper. The structure consists of a stool, a container for raw materials, knives, a shaft and a bearing with a housing. Assembly:

A 12 mm hole is made in the stool.
Under the hole, from the inside of the stool, a housing with a bearing .
A similar hole is made in the center of the bucket. The bucket is placed on a stool and secured with self-tapping screws.
A knife is prepared from high-speed steel R18. A diamond-shaped knife copes better with fresh grass. Its cutting edge is sharpened at an angle to the edges. If the blade is rounded, the grass will not wrap around the knife. It will slide along the cutting part of the knife right on the edge.
A shaft is installed in the bearing and a knife is secured to it.
A drill is connected to the bottom side of the stool. It is connected to the shaft shank using a clamping chuck. The device is ready, let's check its operation.

The grass is placed in a bucket and the drill is turned on. When the grass is chopped, the tool is turned off and removed. The drill can be used for other purposes.

Device from the Typhoon vacuum cleaner

A DIY grass cutter made from a vacuum cleaner has higher performance and looks better. The principle of operation of the device is the same as that of other grass grinders, only the grass is fed through the top hole. And the ground silage will pour out through the bottom hole. To prevent the silage from flying away in all directions, the lower hole is covered with a protective cover. A bucket is used as a silo receiver.

The body of the Typhoon vacuum cleaner has the appropriate hole size required for the device. You can replace the body with a piece of pipe, an old saucepan or a bucket.
We take out the engine from an old washing machine. Its power must be at least 180 watts.
Old hacksaws are used as knives. A sleeve 40 mm long is made on a lathe, onto which the knives will be attached. Two holes are drilled on the bushing.
The engine is mounted on the housing.
Knives fixed to the shaft are mounted on the engine.
For the rack, take a rectangular profile (15×15).

To prevent damage to the electric motor, the racks must be firmly secured.

Grass cutter from a grinder

Any craftsman will find a grinder in his household, which will make a good device for grinding grass. A wooden or metal box are installed on the frame . The voltage to the shaft is transmitted through the saw motor. The blender blades are mounted on the shaft. The silage container is located under the box in which the grass is cut.

From improvised means

Unnecessary things that are lying around in the shed will be useful for making a grass cutter. To assemble the device you will need:

Any round container. An old aluminum pan will do.
Any electric motor with a rotation speed of up to 3 thousand rpm. You can use the Agidel pump. A prerequisite is that it must be connected to a 220 V network.
To start the engine, you need a button . It can be removed from the washing machine.
Electrical wire and plug.
For knives, use old wood hacksaws.

All parts are assembled into a single structure according to the same principle as other models.
