How to make a mower from a motor.

How to make a lawn mower from an engine from a washing machine

Continuing the theme of the ideal summer cottage, we invent new tools and devices to maintain a worthy type of summer cottage. The largest problem of any site is extra grass. It always grows. Starting from spring, ending in late autumn. To maintain the desired level of herbaceous cover, we need a lawn mower. Today we will consider how to make a lawn mower from a washing machine with your own hands. No, we haven’t gone crazy. From the washing machine we will take only some elements!

The manufacture of such a device has long been practiced among country needlemen. Unfortunately, for the manufacture of such a lawn mower, you will need to sacrifice your washing machine or buy a separate engine from it. The gas mower from the engine from the washing machine is one of the most popular acting summer cottages. In principle, to make a lawn mower, you can use absolutely any medium.power electric engine, but we will try to make it from a washing machine. So, if you have an old unnecessary washing machine, and you do not have grass on the site, then this homemade is for you.

Advantages and disadvantages of the lawn mower from the engine from the washing machine

Such a lawn mower has many advantages that make it the best homemade. It can be done in a couple of hours in your garage, having in the assortment the most elementary things that are lying in the courtyard of each Plyushkin. And if you do not have, then the neighbor will definitely have some part of the materials you need. And so, what will we need for the lawn mower from the washing machine:

  • Washing machine engine
  • 4 wheels of small diameter (baby stroller, trolley)
  • Metal sheet with a thickness of 2 to 4 mm.
  • Small pipe for the handle.
  • Cable, fork, switch.

Why such a lawn mower is very popular among homemade? The answer is simple:

make, mower, motor
  • Availability. Absolutely all materials can be found in your site or buy at the acceptance of secondary raw materials for a few pennies.
  • Simplicity of design. You can make a lawn mower from a washing machine from improvised materials. No complex calculations and geometric tasks. Everything can be done on the knee with a hammer and screwdriver.
  • Efficiency. The engine from the washing machine has sufficient power to cope with any grass. Another advantage of such an engine is a small level of noise and smoothness.
  • Repair. If you were able to make such a lawn mower yourself, then no problems will arise in the repair.

Given that the lawn mower from the washing machine can be made without spending a dime, then what shortcomings can be discussed? They are so insignificant that you can just close your eyes to everything. The most global is the appearance of the entire structure. Despite the fact that it is simple to disgrace. at the same time it looks a little frightening and unsafe. But this is only at first glance!

Methods for making a boat motor from a trimmer for grass

There are three ways to make a boat motor from a trimmer for grass. Between themselves, they differ in the parts used and the principle of independent assembly.

Method

This method stands out by its simplicity and efficiency.

For work, you will need to prepare:

  • the clamp, which is necessary for attaching the device on the boat traffic;
  • rowing screw. it can be bought ready.made in the store. The standard assembly of the node includes a drive made of stainless steel, and adapters that need to be connected to a flexible shaft of household motorcycles. Some models of the screws are delivered along with clamps, so the buyer will need to specify in advance a set of parts included in the set of delivery.

As a rule, in the set to the screw there is already a finished drawing. This makes it possible to save on finding the necessary schemes for work. It takes about 1-1.5 hours to install the boat engine.

Method

To assemble the boat ICE, the manufacturer will need to prepare a corner gearbox that can be removed from the corner grinder. Also, a rowing screw is necessary for alteration. it can be cut out of a sheet of stainless steel and bend the resulting blades at the right angle.

Despite the relatively small step of the screw received, this method of alteration makes it possible to achieve the maximum possible speed from the engine. The only negative is the need for additional engine adjustment for which you can use the pliers.

Method

This method differs from others to make some details for the boat engine with your own hands. This will require a 2-stroke gasoline ICE with a cylinder of 25 cm3. The power of the internal combustion engine from a trimmer for grass should not be less than 0.7 kW, and its weight is not more than 4.5 kg. The unit should be equipped with a bent foot. The engine from a trimmer for grass, which meets all these parameters, will make it possible to move on a boat at a speed of 5 to 8 km/h with a minimum fuel consumption. We will tell you about the principles of its manufacture in more detail below.

Making an engine from an electric screwdriver

Good home.made boats are based on battery screwdrivers. The use of the device in which the battery voltage is 12V is optimal. It will be possible to connect a car battery with a capacity of 45-55 Ah to such an electric meter. The revision will consist of several stages.

Lifting mechanism

The rowing screw of the electric motor for a boat made by yourself should move not only in a horizontal plane, but have a certain limit of immersion and rise completely from the water. The simplest design will be a clamp system to which the engine is mounted. It is rigidly attached to the transza with a steel frame and plate. The clamps are equipped with rings through which the tube will pass. A shaft of steel wire or bar will take place inside. To ensure light sliding inside the tube, the bearings suitable in overall dimensions are pressed.

Gearbox and rowing screw

Electric screwdriver is capable of developing high speeds, which is required when drilling. A homemade electric motor for the boat does not need such high speeds, therefore, to reduce them, a gearbox is installed. The most suitable option is the connection of the gearbox from the corner grinder. In the cartridge of an electric screwdriver, it is enough to squeeze the upper part of the shaft to provide a reliable connection.

The role of the rowing screw can be played by the impeller from the car pump or computer cooler. But such an electric motor made by yourself will not be able to provide the boat the necessary speed. You can make a propeller from a piece of stainless steel 2.5-3.0 mm thick.

  • First you need to cut a square workpiece size 30×30 cm.
  • In the center there is a square with a side length of 5 cm. Diagonal lines are drawn through the corners. They will go through them to a small square.
  • Each petal should be rounded and turned along the axis by 30 degrees.
  • In the central part, a hole is made for attaching to the gearbox.
  • It remains to reliably connect and experience the resulting boat electric motor with your own hands.

Design

The lawn mower can have a complex device due to various options, but at the base of its own, this is just an engine with a knife put on its shaft, fixed on the chassis with a handle. It happens that the shaft with the knife is installed separately and it is tied to the shaft of the engine or belt gear.

  • Gasoline: a lawn mower with such a drive is autonomous, which is very convenient with a large area of ​​the lawn.
  • Electric: you need connection to the mains using the wire, so you can’t go far on such an apparatus.

The lawn mower equipped with an electric drive has a number of advantages:

Elekposilk is a preferred option for a lawn with an area of ​​up to 12 acres.

The platform on which all nodes are installed is called a mowing shield. Below it has sides that prevent the grass from flying up in all directions.

By the number of wheels, the lawn mower are divided into:

  • Two.wheeled: maneuverability characteristic of this device allows you to process hard.to.reach areas. But it is difficult to give the knife a horizontal position, so experience is required to perform an even cut.
  • Three.wheeled: maneuvering is more difficult, but the mower is stable and its knife is strictly horizontal.
  • Four-wheeled: irrational option: the advantages are the same as in 3-wheeled, but you will have to spend one wheel more.

The dimensions of the wheels and other elements are selected so that the knife is located 5-6 cm above the ground. then the cut will be even.

A handle is attached to the chassis to control the lawn mower to the chassis.

make, mower, motor

Unlike the purchased, a home.made mowing cannot be made self.propelled and provided with mechanisms for collecting grass and adjusting the height of the cut. But with the main function, she will successfully cope.

Motivation for creating a tool from improvised materials

First of all, it is necessary to determine which tool will effectively replace a regular manual braid when caring for a site. Perhaps dense ambushes, frequent bushes and flower beds will not provide access to the rounded area, and then the “whirlwinds” of grass will need to be removed manually. DIY lawn mowing need to be assembled for mowing the area, more than 4 acres.

make, mower, motor

Choose a way of putting into the cuts of cutters. the basis for the collection of the necessary nodes. Knives can be set in motion:

  • due to manual exposure, pushing forward of the mechanism, which requires great physical strength;
  • using the electrical energy of single.phase or three.phase current;
  • motor from the battery;
  • using an internal combustion engine, two or four.stroke.

Having decided on the energy component, you will need to choose wheels, handle, platform for collecting a lawn mower with your own hands. Collect the necessary fasteners and components of the connection, protection and connection schemes.

Features of the manufacture of a knife

The performance and efficiency of the lawn mower depends on the quality of the knife. You can make two types yourself:

  • A whole knife. It is made of a solid canvas of steel, the edges of which are pulled at an angle of 60 degrees. A hole is made in the middle to fix the knife to the shaft. A casing is installed in the center of the connection, which prevents the winding of grass on the base. As such a casing, a canne is used.

With the help of the burner, the back of the plate bent, which contributes to uniform mowing.

  • A composite knife. The length of the knife should not exceed 50 cm. If you make it in the form of a trapezoid, then the grass cannot be wrapped on the base. In this case, only the extreme 5 cm of the canvas are sharpened by sharpening. You can also use a whole disk that has advantages over knives: when a stone impact, it does not deform.

Step.by.step creation of a lawn mower from a washing machine

To prepare the base, it is advisable to use the chassis from the stroller or trolley. Then it is enough to fix the canvas on them. But if there is no chassis, corners will be used, which will turn into a frame with the help of welding. Frame dimensions 2.5×2.5 centimeters.

  • Four racks for wheels are welded to the manufactured frame.
  • In addition to the base, a pipe or profile is attached, curved in the form of the letter “P”.
  • A hole for installing the engine is prepared. To do this, the hole is cut at the base into which the engine is lowered down.
  • A lattice is installed in front of the frame. It will prevent a scattering knife from the shaft, and will also allow you to even download the lawn.
  • A homemade knife is installed on the shaft of the motor.
  • The pen is attached to the base. A switch is installed on the handle for convenience.
  • A cable is brought to the engine, another end with a fork is connected to the network.

Follow security measures. If you used profile pipes as a handle, be sure to cover them with rubber overlays to avoid shock.

As you can see, you can make an lawn mower with an engine from a washing machine yourself. This is a simple and effective design that does not require additional costs from you.

Necessary materials and tools

A device such as an electric shovel with your own hands is not a matter of first necessity. But the presence of such an instrument at home will significantly save labor costs with the mowing of grass. Very simple lawn mower can be made even from an electric motor. They include the same details and functionality as the factory analogues.

Lawn mowers on an electric motor include:

  • an electric motor or a drive mechanism, with which nozzles rotate;
  • the basis of the frame on which all the details of the mechanism will be held;
  • protective shield;
  • the handle with which the mechanism is controlled;
  • Load knives;
  • 2-4 wheels;
  • button for turning on and off the mechanism;
  • power cable;
  • a capacity for collecting grass or its removal.

It is necessary to constantly observe the safety of the work, and therefore you need to mount an element of emergency and automatic shutdown of the electric shock.

All electrocosylins have the same principle of operation. After the voltage supply to the electric motor, its shaft begins to rotate. And since knives are fixed on the shaft, they cut the grass at high speeds of the electric motor.

The choice of a suitable engine

As a motor for a lawn mower, you can use the engine:

If you need to pump out small sites, then just right there will be an engine from the old drill. It does not even need to be disassembled, just fix it in an upright position.

DIY lawn mowing from a washing machine or a Soviet.style vacuum cleaner can be made without much effort. They have all the necessary details. The best option for mowing grass near the house is an electric motor with a capacity of 0.5 kilowatts, and the recommended number of revolutions is about three thousand. The quality of work and the mowing of the grass depends on the speed of the motor, and accordingly its blades.

The longer the knives of the device, the smaller speeds you can use it due to an increase in linear speed. But its power should increase in order to fight an increasing load. In practice, it has been proven that for home needs there is enough device with a capacity of one kilowatts and engine speed one and a half thousand. over, the working plane is half a meter. In the event that the engine power is less than these indicators, then you need to regularly undermine the blades to obtain the desired result.

If only three phases were found in the farm, then the start.up capacitors must be added to this design. They must correspond to the engine capacity. Drawings of the lawn mowed from corner grinders or other starting materials can be easily found on the Internet or specialized literature.

Additional materials for the design

Knives are intended for direct mowing of the grass. In order to make them yourself, you need to prepare plates of steel up to 45 centimeters long, 3-4 centimeters wide, and 2-3 mm thick. Thin knives are better and better mowing grass, and thick are more durable.

They can be made in three variations:

  • One strip that has exactly in the center of the hole, and the sharpened edges on the right sides. Its length should be from thirty to fifty centimeters.
  • The design consisting of two parts that are mounted on a continuous rib is fixed using bolts.
  • A sharpened disk.

To save wheels and material for handles, you can take from the old baby stroller. When choosing the diameter of the wheels, it must be borne in mind that the distance between the Earth and the blade should be no more than 5 centimeters. If possible, it is necessary to adjust the height of the planting of the lawn mower. When the cutting part of the device consists of two elements, then maneuverability improves, and if from 3-4, then reliability. Such wheels can also be made from plywood and mounted on a shaft with bearings.

The casing for protection against blades can be made from plywood, steel barrel or body of the old washing machine. over, in such an element of the lawn mower it is necessary to make holes for the normal functioning of the electric motor and admission to the closed part.

The body of the washing machine can also be used to create a casing around the blades. Longerons for the motor are made of plywood or sheet of steel. The cord for connecting the device to the network must be selected taking into account the power of the motor. As an option, you can take it from old devices.

In order to make a knife for the lawn mower with your own hands, as well as all other structural elements, you need to prepare the required materials in advance:

  • electric drill;
  • a hammer;
  • corner grinder with a disk;
  • lobby with a set of files;
  • pencil;
  • roulette;
  • pliers;
  • vise;
  • sandpaper;
  • screwdriver;
  • welding;
  • wires;
  • Turning and off button;
  • set of bolts and nuts;
  • corners;
  • Wooden bars.

As an alternative to a corner grinder or an electrician, you can use a hacksaw for metal or wood, but with small teeth. And also experts always recommend drawing a manufactured apparatus to have an idea of ​​the future structure.

The principles of the electric motor

A similar engine can be as single.phase, which works from a regular network, and three.phase, in need of additional electricity. By connecting an electric motor, you must always remember about personal safety. For an engine operating on one phase, protection of the RCD must be installed, and the three.phase motor must have the appropriate capacitors.

For a home lawn mower, you can also use a drill with revolutions up to three thousand. When collecting the structure, it is necessary to choose the right hay of the haymaking to its crook. The battery or electric drill mounted on the basis of or platform will fulfill its tasks, and the grass will be doused.

HOW TO MAKE A MAGNIFICENT ELECTRIC LAWN MOWER

In the process, one should not forget about the intervals of work, since you need to give the motor time to relax in order to avoid overheating. Such a tool will easily clean the territory of the grass and give the lawn an attractive look. The platform on which the engine is installed should be of optimal size so that you can mow grass near the wall.

How to make a boat motor with your own hands from a trimmer for grass?

To assemble a motor from a trimmer for grass to a boat, the manufacturer will need to prepare the following equipment and materials:

  • household lawn mower;
  • clamp. If it is not, then you can use any other mount for reliable fixation of the motor on the boat;
  • a sheet of duralumin, the thickness of which should not be less than 2 mm;
  • welding machine;
  • set of fasteners;
  • set of screwdrivers and wretched keys.

To assemble a home.made rowing screw, the manufacturer will need drawings. They should indicate the exact dimensions of the blades and the method of fixing them on the axis.

It must be remembered that the lower the power of the drive used and the mass of the boat, the less should there be a blades. For example, a screw with blades 10 × 3 cm is suitable for a boat with a mass of not more than 120 kg.

After the preparation of equipment and a thorough study of drawings, you can start assembling homemade.

The work algorithm should look as follows:

  • First of all, the manufacturer will need to finalize a bent shaft. First you need to dismantle the factory nut placed in a bobbin with a pre.wound fishing line. The nut itself in shape resembles a small 2-centimeter tube with internal thread. If necessary, it can be divided into 2 small full.fledged nuts. During the dismantling of fasteners, you need to be extremely careful so as not to lose them. If this happens, then finding another suitable fastener can no longer work;
  • After dismantling the nut, you will need to dismantle the plastic pad located on the gas button. There are no roller bearings at the end of the standard curved rod. They are replaced by an ordinary bronze sleeve, which is often called a sliding bearing. It needs to be gently extracted. Before this, you will need to unscrew the nut, as well as remove the daily and metal shafts from the tube;
  • Then you need to go to knocking out a plastic tread located on a flexible shaft. In the future, the steel pipe can be thrown away, since it will not be possible to align it with improvised means. It can be replaced by a duralumin pipe with the same diameter. It will need to install a bronze sleeve, which will need to be moved by a canvas using a hammer. Next, you need to take a plastic tread pre.trimmed in diameter, and install it on the pipe;
  • The next step will be the manufacture of the screw. To do this, you need to cut out duralumin blades and sharpen their edges. After that, each blade will need to bend up 1 cm up so that the screw step is at least 10 cm. You can fix the finished device using a nut;
  • Next, you need to install a bicycle speed switch on the boat motor from motorcycles, which will replace the standard plastic lining. After that, you will need to install a silencer that will take the engine exhaust away from the boat driver;
  • To fix the boat engine from the lawn mower, you need to use two plywood sheets. After that, the shaft will remain using 4 screws for this. During the transportation of a boat motor from a trimmer for grass, the shaft can be removed.

After the homemade nozzle is ready, it will need to run into. To do this, prepare a fuel mixture of fresh gasoline and motor oil in a ratio of 40: 1. After that, you will need to pour the finished mixture into a standard boat engine tank, start it, and let it develop 1 full fuel tank at idle. After running in, a home.made boat motor from a trimmer for grass will be completely ready to work.

How to use a boat motor from motorcycles correctly?

Using a trimmer for grass, like a boat motor, the operator needs to constantly monitor the condition of the engine, and give him time to cool.

In addition, to extend the operating life of a boat motor from a trimmer for grass will help:

  • Checking all the mounts available in the device. before each launch of the motor, you need to carefully inspect the latches that hold the engine elements from the trimmer for the grass;
  • the engine is refueling from the trimmer for grass only with the gasoline and oil that was used for operation of motorcycles;
  • timely cleaning and replacing the air and fuel filter of the engine;
  • regular verification and timely replacement of the fuel pump;
  • inspection and, if necessary, replacing the spark plug.

The regular ventilation of its standard cylinder will also help to extend the operating time of the boat ICE from a trimmer for grass. To do this, about once every 2 months, you need to twist the spark plug, and it is rarely possible to pull the starter cable 4-5 times. After the procedure, the candle can be screwed back to the place and continue the operation of the engine.

Wheels

The wheels provide convenience when working, allowing the mowing it is easy to move. It has already been said that the most optimal option for choosing wheels is a baby stroller. But, the wheels from the vacuum cleaner, a large children’s machine are also suitable. In extreme cases, they are cut out of wood.

The diameter of the wheels for a homemade electric mowel is selected based on the fact that the distance between the earth and the knife is 5-6 cm. The height is such optimal in terms of aesthetics and the quality of the trim of the lawn. With a higher cut of grass, the latter is “broken” and the lawn becomes uneven. If you reduce this value, it is dangerous to work due to the irregularity of the Earth.

There is no consensus about the required number of wheels. It can be 2.3 or 4 wheels.

Two wheels of structures give maneuverability, allow you to cut grass even in hard.to.reach places. And finding their same diameter is easier than 3 or 4.

In the latter case, it is possible to very accurately set the distance to the ground of the knives. In a three.wheeled device, the steam steam is located from the side of the handle so that the design is easy to raise in front and make a turn, pressing on the handle.

It is more difficult to work with small wheels, why it is recommended to choose more than their diameter.

Making the frame

The frame is made from thick plywood or metal. So that the home.made design is safe and less often needs to be repaired, a protective casing is also needed. The best material for its manufacture will be metal.

The size of this part depends on the length of the knife. But, rarely, when the maximum width is made more than 60 cm. Taking a sheet of metal with a thickness of at least 3 mm, cut a square 50×50 cm (or 60x60cm). The hole for the engine must be made in the center (at the intersection of the diagonals of the square).

make, mower, motor

The flange engine is mounted from below directly to a home.made frame. To reliably fix the motor with ears, additional mounts will be required, which must be welded to the frame.

The metal frame is more reliable and less susceptible to deformations. But, if there is no metal, you can make it from plywood or boards.

The casing is necessary to prevent the crash of weeds and other garbage. The simplest option would be to use a canine as it as it. If you want to make a casing, you can more aesthetic appearance. High casing will be protection for the electrical mechanism.

Creation of a lawn mower from a washing machine

Making a lawn mower with a motor from a washing machine is quite simple for a beginner. To do this, take into account the algorithm during the assembly process:

  • To do this, use a motor equipped with a launch relay and a condenser;
  • After that, we will use a metal sheet, the size of which should be 35 by 55 cm. In the center we make a through hole that helps to remove the torque on the engine outside the cutting zone;
  • Gently fix the engine in the middle of the iron frame so that its active part protrudes a little under a metal sheet.

What will we make a knife from? For this purpose, we will use a steel strip, which we will grind at an acute angle. In the middle we will make a through hole that helps fix it with the driving part of the motor.

  • Now it is necessary to pull out the flange that helps fix the knife and the motor itself. Thus, in the process of starting the device, the cutting part will not be able to jump under the influence of torque.
  • Carefully put on the knife using the flange on the engine shaft itself in its lower part. We will use these goals of several bolts that we will fix on the surface of the shaft. The selection of consumables should be carried out taking into account the thickness of the cutting part and the length of the driving moment.

We fix the wheels with the help of metal corners along the perimeter of the metal sheet. The distance of the knife between the Earth should be 5 cm. Depending on the variety of grass, the position of the cutting base can be changed using bolts.

Before fastening the handle to the surface of the metal sheet, you should carefully remove the electrical wire so as not to damage it during the use of the entire installation.

We will use the island as fixers. Along the perimeter of the metal support, we make 5-6 points that help fix the power source in a stationary state.

Creation of a corner grinder mowel

Corner grinder can be used as a basis that helps to recreate portable equipment for mowing weed and lawn vegetation. In this case, you can use any type of electrical appliances with a powerful motor.

To fix the corner grinder on the surface of the lawn mower, it is recommended to use thick metal. It acts as a protective box that reduces the likelihood of a breakdown of all installations.

In addition, the iron frame will help prevent the scattering of weed grass at the time of its mowing.

  • After creating the frame, it is necessary to gently weld the guide handle to it. You can make it from a thin profiled pipe, which will be fixed in the side parts of the frame.
  • Such a corner grinder can be improved. To do this, wrap a long nut with uniform thread on the work surface. After that, the electric tool must be fixed so that its pulley is located opposite the earth. We will fix the cutting base to it.
  • For these purposes, you can use a ready.made saw disk designed for mowing grass or also create it yourself.
  • To do this, we will use a thin metal bar, one part of which we will grind at an angle of 30-45 degrees. We connect them with each other in the form of a cross, and in the middle we make a through hole designed for a nut and a bolt.

You can attach the cutting part to the power unit using a united nut and a special bolt. The diameter should be calculated based on the size of the pulley.

With the help of a enclosing casing, it is possible to protect the surrounding space from small stones and cutting part of the entire installation. For these purposes, you can use two details.

The final stage will be the installation of the wheels responsible for the mobility of the design during its operation. For unhindered movement, 2-3 elements are required, which should be located at the same distance from each other.
