A neatly trimmed lawn is not only beautiful in itself, but also in a certain way indicates the status of the owner of the house. Nowadays, it is not difficult to find a lawn mower that is suitable for its performance and design. But there is another option. If you have a medium-power electric motor lying around on the farm, then after spending a few evenings, you can easily turn it into a simple and convenient homemade lawn mower, saving not such a small amount of money that you would have to pay for a branded lawn mower - and even enjoying creativity.

General structure of the lawn mower

In its simplest form, a lawn mower consists of the following components and parts:

Engine.
The frame on which all mower components are attached.
Knives.
Protective casing.
Wheels.
Handles for control.
Control system parts: switch, RCD, power cable with plug.

The frame of the simplest design is a metal sheet 2-3 mm thick with a hole in the middle for the passage of the motor shaft. The sheet is reinforced with a frame of metal corners. The engine is attached to the sheet at the top, a protective casing at the bottom, an axle for the wheels on the sides, and handles for control.

If the motor is flanged, it can be attached directly to the sheet by drilling holes in the latter that coincide with the holes in the flange. If the engine is of a conventional design, it is necessary to weld or screw two perpendicular corner posts to the sheet so that they coincide with the engine feet.

Homemade lawn mower. Fastening the electric motor to the corners.

Holes are drilled in the corners for mounting the engine. If the holes are made in the form of grooves, this will allow the engine to be shifted relative to the frame when mounting, thus changing the distance from the knives to the ground. This design feature will be useful when selecting optimal height cutting grass. But it’s easier to make holes for different engine height positions.

The central place of the lawn mower is the cutting unit, consisting of a mandrel with two short (or one long) knives attached to it.

Engine

A good option is asynchronous electric motor power 500-600 W and above, with a speed of about 3000 rpm. The big advantage of an asynchronous motor is its low noise level. The higher the engine speed, the better and smoother the haircut. In fact, the quality of mowing is determined not by the speed of rotation of the blades, but by the linear speed of movement of the cutting edge relative to the grass. At the same engine speed, the higher the linear speed of the cutters, the larger the grip (the diameter of the circle along which the cutting edge rotates). Therefore, with a large grip (more than 40 cm), the engine speed may be lower. However, in this case, the motor power must be greater in order to overcome the increasing resistance. Practice shows that this option is quite workable: grip - 50 cm, engine power - 1 kW, speed - 1500 rpm. But in principle, a 500 W motor with a frequency of 1500 rpm will mow the grass, although worse. Only with low engine power, you need to sharpen the knives regularly.

To connect a three-phase motor to a single-phase network, it is necessary to use a circuit with working and starting capacitors. Connection information three-phase motors There is plenty of access to a single-phase network on the Internet. It is not difficult to find formulas for calculating the required capacitance of capacitors. In practice, they take approximately 200 uF for a motor with a power of about 2 kW. For a power of 500-600 W, 60-80 uF is sufficient.

When making a casing for the engine, you need to provide holes for cooling the engine.

You can make a lawn mower with your own hands using a conventional electric drill with a speed of up to 3000 rpm. Coming up with a way to attach a drill to a frame is not that difficult. However, you need to understand that in terms of reliability and duration of continuous operation, the drill cannot be compared with asynchronous motor, so if you have a relatively large area to mow, preference should be given to the latter.

A drill is more suitable for making a homemade trimmer.

In the case of a drill, it is very simple to mount the knife. The knife with the hole in the center is clamped with a nut on the bolt, and the bolt is clamped in the drill chuck.

Mandrel

Most simple design mandrel is a disk or strip with a flange in which there is a hole, equal to diameter motor shaft. The flange is put on the shaft and locked on it, knives are attached to the disk or strip. The diameter of the disk or the length of the strip depends on the planned working width and the length of the knives. As a finished mandrel, you can use a pulley with a landing diameter suitable for the shaft of the existing engine. This will solve two problems at once - centering the mandrel and its fastening. But the pulley must be reliable enough.

The mandrel must be securely fastened to the motor shaft. This is usually done using bolts screwed into the flange perpendicular to the shaft axis.

You can use a stone holder for a sharpener as a mandrel.

To prevent grass from wrapping around the shaft, it can be covered with a tin can.

If a suitable pulley or other suitable parts are not found, you will have to order the manufacture of a mandrel from a turner or make it yourself from a pipe of a suitable diameter and a strip or circle welded to it. There are three problems here: finding a pipe of suitable diameter, ensuring the perpendicularity of the welded strip or circle with respect to the pipe, and centering the mandrel after its manufacture. With some effort, all these problems can be solved.

Knives

Flat tool steel with a thickness of 2-3 mm and a width of 20 to 50 mm is used as knives. The thinner the knife, the better it cuts. However, a thick knife is stronger, which, given the obstacles encountered in its path in the form of bumps, various foreign objects and even stones, is very important.

The design of knives has two main options. The first is a knife in the form of a long strip, which is attached to the mandrel symmetrically relative to its axis. The length of the knife in this case is equal to the width of the grip - usually 30-50 cm. The sharpened ends of the strip act as cutters. In this case, the knife and the mandrel can be one integral part in the form of a plate, to which a flange with a mounting hole is welded or riveted.

The second option is two short knives 50-80 mm long, which are attached to the edges of the mandrel at an angle of 180° to each other. They can be positioned straight or with a slight slope. The knives can be secured with two or one bolt. The first method is more reliable, however, fastening with one bolt allows the knife to fold (without breaking or deforming) when it hits an obstacle - a stone or a bump. The fastening of folding knives must be inspected regularly, because... Over time, the screws may wear out.

The steel for knives must be sufficiently hard, but not brittle, otherwise the knives may break, which will not only require their replacement, but also create the risk of injury from a flying piece. The experience of amateur craftsmen shows that wood hacksaw blades 2 mm thick are very suitable as a material for lawn mower blades. The technology for making a knife from them is simple. Two strip-shaped blanks are marked on the canvas (or one long knife is made from the canvas with sharpening at the ends and holes for fastening in the middle), which are then cut out with a grinder. Holes for fastening are drilled in the workpieces. After this, all that remains is to sharpen the knives, attach them to the frame and center them.

If drilling holes is problematic, then you can lay the canvas on metal surface with a hole of a slightly larger diameter than the hole in the canvas should be, and hit it with a punch. The protrusion formed after the impact is removed with a file (if the metal is soft enough) or with a sharpener. If the hole doesn't respond required diameter, the process is repeated.

In essence, there are many options for making functional knives, as well as materials for making them. The main thing is to sharpen them well, center them (so that there is no vibration) and securely fasten them. When attaching knives to the mandrel, you need to use lock washers and locknuts. Without this, the mounting bolts will unscrew due to vibration.

If possible, it is better to make the cutting edges slightly curved down, like on branded lawn mowers. This will reduce the grass from wrapping around the motor shaft. Or you can make a disk that covers the shaft. Also, if the engine power is close to the power of branded lawn mowers, you can buy a branded lawn mower blade ().

Wheels

The diameter and position of the wheels must be selected so that the knives are located at a distance of 5-6 cm from the ground. This mowing height is considered optimal - both from the point of view of the aesthetics of the lawn and the quality of the haircut. If the grass is cut at too high a height, it will bend, allowing the blades to pass above it and remain uncut. Cutting lower is difficult due to the unevenness of the ground.

There is no clear opinion about what number of wheels is optimal - 2, 3 or 4, among craftsmen operating homemade lawn mowers. 3 or 4 wheels are good because they set the exact distance from the knives to the ground. Two wheels make the lawn mower more maneuverable and allow you to cut grass in any hidden places. In addition, it is easier to find two identical wheels than three or four. However, you can make the wheels yourself, for example from plywood and bearings, so the last argument is not so convincing. Ultimately, the choice remains with the master himself.

If a two-wheeled lawn mower is selected, there must be protection against the rotating blade touching the ground.

If you choose a three-wheeled lawnmower, then two wheels should be on the handle side so that you can lift the front of the mower for a turn by pressing on the handle.

The larger the wheel diameter, the better. A lawn mower with small wheels is more difficult to push through grass.

If the edge opposite the cutting edge of the knives is bent upward (or blades are riveted to them), they will work like a fan, lifting and rotating the cut grass with a stream of air. At the same time, if you make a cut in the casing (in the quadrant where the knives run) and pull a mesh bag or box over it, then the cut grass will be collected in it.

At the end of the article there is a video demonstrating the operation of the second lawn mower.

Without a bag, the grass will be laid in the direction specified by the cutout. Without a hole in the casing, the grass will be crushed, this will be mulching. But for all this you need a fairly powerful engine, and in order to avoid cutting grass from stuffing into the engine, the space between the engine and the knives must be covered with a disk.

Working with the mower will be safer if one of the handles is equipped with a lever that, when released, turns off the power supply to the engine.

Security measures

When starting to make a lawn mower with your own hands, you need to understand the dangers posed by the operation of such devices. If we talk about the main threats, there are two of them: defeat electric shock and injury from rotating knives. Both are classified as very serious, so safety measures must be taken very carefully.

It is necessary to carefully insulate all electrical wire connection points - both on the engine itself and on the control parts. The insulation on the supply cable must not be damaged. To power an electric motor, you must have a double-insulated cable with at least 3 cores. The mower body is reliably grounded, for which one of the cable cores is used. Or they connect the lawn mower to the network using an RCD - a residual current device designed to de-energize electrical devices when a person touches their parts that are energized due to insulation failure.

Do not operate the mower without a protective cover. When working, you need to make sure that there are no people nearby. Broken knives fly out at high speed. And if the operator himself is protected by a casing, then in some designs of homemade lawn mowers, the front area of the mower remains open. It is advisable to mow in rubber boots. This will protect you from the consequences of falling into various objects that are thrown away by the rotating knife.

Do not use the mower in wet weather or early in the morning when there is dew.

Below is an example of a homemade lawnmower gone wrong.

The engine is completely open, and there is no homemade casing for it, not even a protective disk on the blade side, although there is a huge hole there. There is no cover to protect the lawnmower from flying blades or thrown stones. The handles are welded and cannot be adjusted in angle; in addition, they cannot be removed when storing or transporting the lawn mower.

Any personal plot needs grass mowing. An electric or gasoline trimmer is expensive, and not every owner can afford to buy one. Therefore, some craftsmen have learned to make their own trimmer from an angle grinder.

From the Bulgarian

Every master has a grinder. This is the most suitable tool to create a trimmer. Unlike store-bought devices, it is stronger in power and has good speed. Let's look at how to make a trimmer from an angle grinder with your own hands, the order of work:

First, prepare the bracket. It is designed to fit around the body of the angle grinder. metal plate applied to the body and bent.
On both sides of the case there are threaded holes in which the reversible handle is attached. The trimmer bracket is attached to them.
Holes are drilled in the bracket on both sides so that they correspond to the openings located on the tool body. For accuracy, marks are made on the part with a marker, clamped in a vice and drilled.
Then a guide is attached to the bracket. Its size should match the length of the body or be slightly shorter. The guide is attached welding machine, the remaining scale is knocked off. The part is polished with a metal brush.
A handle (bar) is made from a metal pipe. To secure the handle at a slope, the tip of the pipe is cut off at a bevel. The finished handle is welded to the structure, the scale is knocked off and the part is cleaned with a brush.
To attach the tool, you need to unscrew the protective disk of the angle grinder.
Then the homemade product is installed on wheels. To do this, you can borrow wheels from a cart or baby stroller with brackets.
First, install the grinder, then the wheel with bracket. Everything is secured with a bolt. On the other side they make the same fasteners.
The cutting unit is made from steel cable. A nylon wire designed for trimmers is suitable. It is threaded through the clamping nut and the key hole using the criss-cross method. Then the nut is tightened together with the cables.
The wire is fixed with electrical tape.

How to put a knife on a trimmer

With the arrival of summer, many homeowners are worried about the question of how to put a knife on a trimmer. More pressing questions are why and when to purposefully replace the fishing line on a lawn mower with a stronger cutting element. In our article we will try to sort it all out and give useful tips summer residents

Why you need to put a knife on a trimmer

A trimmer with a knife installed on it is more convenient total use for more comfortable mowing of tall and coarse grass in the countryside. In such cases, the line on the brush cutter does not control. Installing a knife on a Chinese trimmer: how to remove and install old chain. The narrow one breaks very quickly. Discussion of the stihl fs 55 trimmer on the casing below, I don’t understand how to install the bobbin. The introduction of a thick 2.3 mm cord or homemade rods with cables forces the vegetation to wind onto the spool. This increases the load on the engine. As a result, the piston group and other moving parts of the unit wear out very quickly.

If you mow weeds with an electronic trimmer without a knife, using fishing line alone, even a thick one with a shaped cross-section, the problem will not be solved. There is always a risk of overheating the electric motor and damaging the flexible shaft. And it's all about the high torque of the electronic motor. The grass wound around the spindle creates strong resistance to the shaft, reminiscent of a speedometer cable, which cannot withstand it and gets twisted.

In order to protect equipment from early wear and tear, manufacturers have provided the possibility of installing special knives on trimmers. The design and shape of the existing cutting parts allows you to easily handle not only coarsened and overgrown grass, but also successfully fight with young bushes.

What knives to put on electric and lawn mowers

Before you take a knife and put it on a lawn mower, let’s find out what they are and in what cases they are used. Now manufacturers offer consumers a huge number of types of these Supplies. In general all cutting tool, intended for mowing grass, can be systematized:

By the type of material from which it is made;
According to the shape of its cutting blades.

The main material for the production of trimmer knives can be plastic or metal. The implementation of such consumable parts almost entirely depends on two characteristics:

A straight shaft for a gasoline trimmer and a curved one for an electric trimmer

Its design features do not allow placing a metal knife on an electric trimmer.

The curved rod of the unit reduces the distance from its working part to the mower’s feet. If the blades collide with a stone or other hard object, the scythe is thrown towards the feet.
The high torque that we mentioned above, in the event of a collision between a metal blade and a hard object, transfers a large load to the flexible shaft of the trimmer and its motor. What causes their premature failure.
The handle of an electric scythe most often does not have a limiting bar that acts as a stop. But you should not rely only on them, since this is not what the casing of the cutting trimmer is designed for. This does not exclude leg injury.

It is these features that allow it to be used on trimmers with electric motors exclusively plastic knives. When colliding with an obstacle, the blades are destroyed, thereby protecting the mower’s legs from possible injury.

Plastic knives work well with overgrown and dry grass. They can mow down nettles and burdock stems.

The use of metal knives only on gasoline trimmers is also due to design features.

The straight design of the boom increases the distance to the legs, which ensures complete safety for the mower.
Comfortable U-shaped and J-shaped handles allow you to hold the tool firmly. The D-shaped handles of the lawn mowers are equipped with a limiter that rests against the leg of the mower, which does not allow the head to be allowed to approach the legs when meeting cutting disc with a solid obstacle.
The clutch of a gasoline engine allows you to smoothly gain speed to the optimal level. And when the blade collides with a hard surface, it is able to absorb part of the impact.

Thus, gasoline trimmers with a metal blade installed are best used in large areas. They will successfully cope not only with tall, coarse grass, weeds, burdocks and nettles, but also shrubs, as well as young trees.

The shape of the blades of the disc placed on trimmer does not in any way affect the quality of the work performed. Speed does not depend on them either. Triangular, trapezoidal, rectangular shapes are all a marketing ploy by manufacturers.

If you plan to make hay, it is best to use knives with a large number of blades on your brush cutter. Look for discs with eight teeth or discs with four large blades and four additional ones. Two and three bladed knives will chop up the grass greatly.

How to properly place a knife on a trimmer

Put cutting a knife onto a trimmer is not that difficult. The manufacturer equips its tools with a special pin that allows you to lock the gearbox and a key with which you can unscrew the spool with fishing line. The most important thing is to observe safety precautions and the sequence of assembly and disassembly when changing cutting elements.

The algorithm for installing the knife on the trimmer is as follows:

We remove the protective casing;
We block the drive. To do this, you need to align two holes - in the shaft hub and in the gearbox cup. After aligning them, insert a pin into the holes;
Unscrew the spool with fishing line clockwise from the hub or fastening nut holding the boot (if the trimmer has not yet been used);
Next, install the cutting knife so that the slots on the hub washer coincide with the recesses in the hole of the cutting disc;
Install the boot;
Tighten the fastening nut (counterclockwise) while holding the locking pin;
Tighten it using a tubular wrench;
We return the protective casing to its place.

Hand trimmers mow vegetation either with a fishing line or with knives. At the beginning, the functionality of the trimmer is limited to mowing soft grass with normal and low height, since plant debris is wound onto a flexible shaft, or in other words, sticks to the spool. By installing a trimmer blade, it becomes possible to cut off tougher trunks and trim young bushes.

Types and uses of trimmer knives

The systematization you will like is carried out according to the following characteristics:

Based on the material of the knife: iron and plastic knives are known. The choice is often limited not so much by the user’s desire as by the power of the drive - iron blades are heavier, and the trimmer shaft equipped with them develops more slowly, which adversely affects the durability of the motor. But the cutting ability and durability of iron knives is much higher than that of plastic ones.
For making cutting edges. They are distinguished by significant diversity, and as a rule they come with 4 or more teeth, single or different heights, and also solid or with technological holes.
According to the shape of the knife itself, which has a solid disk blade, or is made in the form of several blades with a similar distance between them.

The choice of the size and design of the trimmer blade depends on the intended purposes, the type of rod and the power of the motor. If the trimmer rod is bent in the shape of a letter J, then there is no need to use a metal knife, since if it comes into contact with a powerful obstacle, nettle, stone, trimmer will be sharply thrown back, towards the mower. Then even the highest restrictive casing will not save the worker from a leg injury. On trimmers with a straight shaft, the rebound distance will increase.

Plastic trimmer blades, although less durable, are quite capable of cutting most types of grass. In addition, their increased elasticity does not create additional loads on flexible shafts electric trimmers.

The configuration of the cutting edges determines the quality of the cut. For hard grass, dead wood, woody shoots, disc blades with the largest number of teeth are better: then, regardless of the speed of rotation flexible shaft, the cut will be clean and even. The inertia of perforated knives is significantly less than solid ones, and this does not particularly affect the durability of the tool, taking into account the fact that the tool is made of high-quality tool steel. The exception is cheap products made in China: there knives are made of any steel.

Where and which knife is better?

When the fishing line’s capabilities are not enough, you should think about replacing it with a metal or plastic knife. If a replacement knife is included with the trimmer, there are no problems: replacing the cutting equipment is done in accordance with the instruction manual for the trimmer. However, this does not happen every time.

Find out the suitability of installing a knife on an existing electronic trimmer(there will be no similar problems with gasoline) there is an option for the actual speed flexible shaft. If, when replacing the spool with fishing line on the knife, the engine reaches the set number of revolutions per second or less, then a replacement is likely, otherwise the engine will overheat very much, and the trimmer gearbox will quickly fail.

It is interesting to compare three more common variants of knives with each other - a multi-toothed disk knife, also with 2 and 3 blades.

Metal disc knives

Usually, several of these knives are included in the trimmer kit, but you can also purchase them separately by measuring the outer diameter of the knife and the configuration of the mounting hole. Nettle, circular cutters from Stihl and Husquarna are interchangeable with each other. Circular knives differ in the number of teeth, height (some have different heights), and also the continuity of the blade. In most cases, such knives are installed on trimmers from Stihl, Huter, AL-KO, equipped with a straight bar, and are more rigid. They handle old growth and long trunks very well, but when working with young grass, the cut material often sticks to the inner surface of the protective casing.

A trimmer with a perforated blade, compared to a solid one, picks up speed faster. The disadvantage of circular knives is the increased moment of inertia, so the starting power of the drive increases. On cheap designs and with frequent stoppages in work, this leads to overheating of the motor and negatively affects its durability.

Two-blade and three-blade knives

These are the knives that he uses to complete his electronic trimmers. trademark Bosch. Their moment of inertia is small and does not actually affect the performance of the drive. The ease of use of this design lies in the fact that separate replacement of all blades is possible. For trimmers of this type, the rod is bent in the shape of a J-shaped blade. Two-bladed knives work stably on a homogeneous mowed mass. They perfectly throw the cut shoots to the side and do not allow residues to stick or wrap around the rod shaft.

Three-blade and two-blade knives are quite competitive with disk knives in their capabilities, but the thickness of the blade should not be less than 2 mm. At the same time, forged knives are more durable than stamped ones (found on Chinese-made trimmers). It is easy to distinguish them - on stamped blades, traces from the cutting punch are clearly visible with the presence of corresponding chipping and shear zones, which is not present on forged ones.

Shark knives

“Shark” is essentially an attachment of three bladed knives, with each blade fixed relative to the other at an angle of 120°. The advantage of this design is that each blade can be customized individually. And therefore, when mowing an area with various types vegetation (grass, weeds, dead wood), the quality of mowing will be approximately the same. Today, since the interval between mowing the grass with each blade is reduced, the discarding of the grass occurs more actively. The “Shark” head is compatible with many standard sizes of electric trimmers and has a small own weight, but requires periodic adjustment of the blades, which are attached to the base with conventional screws.

There is an option to reduce the moment of inertia of the circular knife by independently perforating its surface, nettle, on a punching press. The perforation holes are made to be placed strictly symmetrically relative to the center of mass of the knife. The tool becomes lighter, but its cutting capabilities do not change. Proper sharpening of the blades of the interchangeable knife also has a beneficial effect. It is produced at low speed grinding wheel with normal grain size. The teeth are sharpened at an angle of 30°. You should not use a trimmer knife tipped with carbide - the quality of the cut remains virtually the same, but the weight of the tool will increase.

DIY trimmer knife

It is much easier to make a homemade knife in the blade version. For this purpose you will need:

A piece of pipe (copper is better than metal) of a suitable diameter for the production of an adapter sleeve for the outlet part flexible shaft.
A sheet of steel less than 1 mm wide for the washer.
An ordinary cotter pin in accordance with GOST 397-66, for attaching the base to the trimmer shaft.
Steel strips 1...1.2.4 mm wide for the production of knife blades.
Fasteners (it is better to use rivets rather than screws or a nut for a knife, even if it is included in the original kit).

A view of a homemade trimmer knife is shown in the figure.

Manufacturing equipment is created in this order. First, the general dimensions of the device are marked so as not to go beyond the boundaries of the protective casing. Then a sleeve is made from a piece of pipe. To improve the fit, the bushing is made split and seated along the outer surface of the output part of the trimmer shaft. Since the diameter of the washer is determined only by the dimensions of the available space, it can also be selected from the nearest standard sizes. The washer is welded to the bushing in such a way that the formed seam leg is the smallest.
