How to redo a trimmer for grass with a battery to an electric

Just on the street the weather, softly say, does not correspond to the middle of the first month of spring But it should be noted that it can also swiftly change. Why am I, ask you? And for this, the reader honored, that it is better to cook sledges from the summer, and the trimmer for the grass for the summer season from the winter how to choose a trimmer for the grass so that it serves reliably for more than one year, I wish to tell you further!

Trammers for grass differ in many characteristics, but having highlighted the main ones among them, we have the subsequent division: according to the power source, power, in the location of the motor, in the manner of the drive, in the manner of the handle and, importantly, by weight. We will analyze these main differences expanded:

Battery trimmers for grass. quite fascinating, but an ineffective type of manual lawn mowers, due to low power. Suitable only for the rarest use in small areas with unhurried vegetation, or perfectly complements a more massive four.wheeled counterpart. The batteries are designed for 20-40 minutes of continuous operation, and the charging process sometimes reaches a fairly long period of time, right up to a day. Of the advantages, of course, one cannot fail to note the low weight and independence from the electronic network, which makes this common hearing already small.sized type of trimmer for the grass even more mobile! Virtuoso and frisky mowing of soft grass in inaccessible places, this is exactly his horse!

Electronic trimmers for grass are the most popular type of mowal, often found on the balance of home tools of an ordinary tradesman. Professor model of this type is great uniqueness. The power of trimmers with an electronic engine achieves 1.4 kW, which is quite enough for comfortable use in a summer cottage, even with thick grass. Dependence on electricity sets a certain framework for the introduction of a trimmer for grass. Limited by the length of the cable and the length of the extension cord, will bring significantly less usefulness in huge areas, if the battery otherwise gasoline. The mowing of grass after the rain will also be quite problematic. Nevertheless, it should be noted that electronic trimmers for grass work quite quietly and speaking figuratively have a small weight that allows you to control even old people!

Gasoline trimmers for grass. in most cases, are used for professional purposes or in rather huge areas. The power of gasoline cos is achieved by 3 kW, which on certain models allows you to use in addition to fishing line and knife, as well as a disk or equipment hinged. Gasoline trimmers for grass have a significant weight, which radically limits the time of continuous operation. The engines on gasoline trimmers are both two.stroke, operating on the consistency of gasoline with butter, and four.stroke, in the latter case, gasoline and oil are flooded separately. Four stroke engines consume less fuel, if two.stroke, and the release of harmful substances into the external environment in their less. But it should be borne in mind that the two.stroke version of the motor is easier than four.stroke and almost always cheaper. The gasoline engine braid for grass produces a lot of noise, which leads to a certain misunderstanding of not familiar, especially in the evening! This type of trimmer for grass is limited only by the capacity of the fuel tank, which allows you to create mowing in wide territories, in any weather!

By summing up the result by type of mowing motor, we note that the battery and electronic trimmers for the grass have a small weight and the smallest, in comparison with gasoline, the release of noise. The internal combustion engine, again, is more powerful and universal.

Power is the main parameter that determines the implementation area and the effectiveness of a trimmer for grass. Wallowing the power of the engines, it is worth considering the fact that for mowing grass in even areas that did not overgrown with a hard shrub, there is enough trimmer for grass with a capacity of up to 500 watts. If in this area there is a different vegetation in stiffness and height, overgrown and covered with small shrubs, then for a more confident and effective putting the site a trimmer for a grass with a capacity of 500-1000 watts will be useful in order. In the most neglected areas, it will not do without a trimmer for grass with a knife and power, significantly larger 1 kW.

The engine of the trimmer for the grass contains both the upper and lower motor placement:

• Lower motor placement, most often, is characteristic of battery trimmers, alas, it is found on electronic models. Of the obvious advantages of a similar location of the motor, it is necessary to note a more equilibrium design and the smallest vibration, which allows you to use a trimmer for the grass without abundance, in the course of more time. But a trimmer with a engine located below, you can not mow moist grass.
• The upper motor placement is even more often found and is used by manufacturers on electronic and gasoline trimmers. This placement allows you to use a thicker fishing line for a trimmer in other words of a knife if a passage with gasoline trimmers. Contributes to the mowing even moist grass.

In the manner of the drive there are trimmers for grass both with a flexible shaft inherent in household models and with a hard shaft, more often found on more massive and professional mowers. A hard gearbox shaft is considered more reliable, unlike a flexible damnator shaft. The transmission of rotation from motor to the head in the latter case occurs through a metal cable, in the rigid version, a real shaft with a gearbox, a snot of a spit for grass. Trammers for grass with a curved rod for equipment are used only a fishing line for a trimmer and plastic knives, with a straight line, followed, additionally with metal knives in other words.

In the manner of a handle, it is worth highlighting two frequently encountered species:

• The D-shaped pen prevails in the battery and electronic types of trimmers, does not reduce mobility and immediately with this allows you to hold the tool with 2 hands.
• T-shaped or J-shaped, it is also a bicycle handle, more often found on massive electronic and gasoline models of trimmers, allows you to imitate the movements of an ordinary oblique.

Does it make sense to buy a battery lawn?

To answer this question, it is necessary to determine how it differs from gasoline and purely electric mowers, as well as to disassemble the principle of its work.

The basis of any mitch of this type are:

The battery is essentially a mini source of energy, it can supply the electric motor only by the electricity that has absorbed during the charging process.

Therefore, the battery mower is not fully autonomous, but the time of its operation can be extended by increasing the number of batteries, as well as their constant charging.

In battery lawmakers, direct and alternating current engines are used. The former are equipped with a collector, so they are less reliable, but do not need a complex driver, the latter are much more reliable due to the lack of collector brushes, but the driver (converter) is needed for work.

Another advantage of blessed (brilliant) engines is that the driver regulates the supply of energy, therefore, at those moments when the knife rotates, but the device does not mow the grass, the motor operates in the most economical mode, and the battery supply is spent more economically.

The supply of energy in the battery is limited, so it is very important to spend it with a minimum of losses. In mowers with a direct current collector engine, the driver changes the voltage coming to the windings, so that it is possible to adjust the current without loss of power.

After all, if you limit the current using a resistor or some of its analogue, then part of the electric energy will be turned into a thermal, that is, the battery will lose part of its reserve without any benefit, which cannot always be immediately replenished.

Therefore, the driver limits the voltage, which reduces current consumption, which means that the battery charge is consumed more economically.

Besternal engines operate on a different principle, so their driver converts the constant voltage of the battery into a variable, rectangular shape.

Changing the well, that is, the ratio of the period of voltage supply and its absence, it changes the average voltage, which enters the winding of the electric motor, so that when working without load, its electrical consumption is minimal, which means that the charge is enough for a greater period of time.

On the battery or on gasoline?

The advantages of gasoline devices are:

• high power and the ability to mow even very high grass;
• suitability for mowing vast territories;
• autonomy, because for work they only need gasoline.

Battery mowers cannot compete with gasoline on equal terms, since they are not so powerful, so they are unsuitable for mowing large areas or the fight against thick high grass.

But they are deprived of all the disadvantages of gasoline analogues, that is:

Therefore, their purchase is justified only in the following cases:

• It is necessary to shake well.groomed grass in a small area;
• It is very important to do this without loud noise and the appearance of an unpleasant odor;
• It is difficult to deliver a heavy apparatus to a plot requiring mowing.

Homemade blade of the lawn mower

In this capacity will be the blade of a stationery knife. Two of these are connected with a bolt and pinch in a nut into the cartridge. Do not forget about safety measures and make protection for the lawn mower. You need to cover the side parts and the one that is closer to you. The front one does not need to be closed, otherwise the grass will be swallowed.

It remains to attach four wheels and make a handle. No need to hard, because this is not a racing machine, no bearings are needed. So just four screws are used in the role of the axis. A braid made by the battery.based hands is ready. How cool it works, judge by the video.

DIY electric

In order to make an electric type on your own, you can use the engine from some unnecessary device. Engines that are equipped with household appliances can quickly burn out. Even vacuum cleaners are equipped with weak motors. For the most comfortable operation of a home.made lawn mower, it is advisable to take a motor with a capacity of at least one kilowatt.

The blade can be cut out of a durable steel alloy. You can also use a round disc, imprisoning it in advance.

The handle of the device can be used from the old stroller or trolley. The use of a cart or stroller as a frame of equipment greatly facilitates the production of equipment, but all the constituent structures must be quite strong enough. You can also make a pen of pipes using welding.

The cord, through which it will be supplied with power supply, is recommended to lengthen. The wheels in this case should not be too massive.

First you need to make a metal frame. The motor is mounted on it using bolts. From below the frame is fixed a cutting mechanism that is connected to the motor. Behind it you can place a bag of a carpet.

Around the blades you need to put a casing to protect. The motor and connection with the blades must be reliably closed so that they do not get the grass.

Mechanical lawn mower

Mechanical type equipment emits much less noise, it also does not require energy consumption. With such a lawn mower you can even work in the rain, but it is more difficult to do it. The whole problem is that it is very difficult to choose gears, wheels and blades.

A mower equipped with a pair of blades needs to quickly rotate blades. It should be created thanks to the movement of wheels and gears. The creation of such equipment requires maximum attentiveness and patience from the contractor.

How to make an e.it.retaining trimmer for grass?

To make an electric cost, you will need:

• an electric motor for 220 V or some kind of tool equipped with it (you can use motors of a different voltage, but then you will need a converter or a power supply, and a small size);
• material for the manufacture of the handle;
• button or toggle switch capable of withstanding the current consumption of the engine or electrical appliance (if their maximum current is below, you will have to set the relay);
• a fork from an electrical appliance of the same power;
• wires of sufficient section for connecting the motor, button and fork;
• Materials and equipment for the manufacture of cutting tools.

From sewer pipes PVC

This design is suitable for those who are idle for a working electric motor from a drill or a screwdriver.

Here is the procedure:

• From a pipe with a diameter of 40-50 mm, make a bar of the required length;
• In the lower part, set a tee with an angle of 45 degrees (do not use the corner, because the third part of the fitting will supply air to cool the engine);
• to the lower part of the corner, attach the adapter to the pipe, the diameter of which allows you to install an electric motor;
• From a plug of suitable size, make the lid to which attach the engine;
• Cut the suitable piece of the pipe of the corresponding diameter in length and insert a plug with an electric motor into it;
• Mark the cooling fan and on the perimeter of the pipe in a checkerboard pattern,
• Fasten the cutting tool on the shaft;
• From the right material, make a protective casing and attach it using an adhesive thermal pistol;
• Insert the lid (plug) with an electric motor into the pipe segment and connect the wires;
• Insert a plug into the upper hole of the tee, in which drill 50–100 holes with a diameter of 1 mm;
• In the upper part of the bar, select the most suitable place and install the switch there to which connect the wires, if some driver or other device is needed to work, then connect it;
• On the upper edge of the bar through the coupling, set the plug in which drill a hole for the output of the cable;
• If you work with a straight bar is inconvenient and you have to bend very much, then cut it just below the switch and cut a tee with an angle of 45 degrees there, and insert a piece of pipe with a plug into it, it will be a vertical handle;
• Fix all the connections of the pipes with self.tapping screws.

From an aluminum pipe, plywood and sewer PVC pipe

This design is partially similar to the previous one and is suitable for the same electric motors. The difference is that the bar is made from an aluminum pipe, and a comfortable handle is cut out of plywood. The only difficulty is to fix the motor at the required angle (45 degrees).

This can be done in different ways, from a curved aluminum or steel plate, then a corner from a reinforcement with a diameter of 6 mm, curved at the required angle and attached to the PVC pipe and a bar with clamps or heat.mushrooms.

From corner grinders

An angle grinding machine (angular grinder), which is popularly called the “corner grinder”, is equipped with a high.speed powerful engine that is well suitable for mowing grass.

You can turn it into a trimmer for grass in two ways, that is, by installing:

The advantage of the upper installation angular grinder is the maximum security from scraps of grass, which can damage its electric motor.

In addition, with such a connection, the tooling of the tool is much more successful, so that when working with it you will be more slowly tired.

To install a corner grinder on top, you need a bar and a shaft, so it is easiest to put it on a burned electric trimmer for grass with an upper engine or its gasoline analogue with a faulty power unit.

In this case, the corner grinder will perform the function of not only the electric motor, but also one of the handles. The disadvantage of this approach is that most of the Bulgarians are not equipped with speed adjustment, which is why the fishing line for the trimmer quickly wear out and requires frequent replacement.

A good output in this case is the installation of a revolution regulator from any other device of comparable power, for example, a pedorator or an electrician.

To attach a flexible or hard shaft to the tool, make an adapter equipped on one side with slots, on the other with the corresponding thread.

If the location of the corner grinder across the rod seems inconvenient to you, install a corner gearbox between it and the shaft, which can be bought on Aliexpress or any other site.

The only advantage of installing an angular grinder below is the maximum simplicity of the design, because an intermediate shaft or an additional gearbox is not required here, because the cutting tool mounted on an angular grinder rotates parallel to the ground.

This scheme has more disadvantages:

• We have to invent different methods of attaching the device to the bar at a certain angle;
• The grass flying during mowing often clogs ventilation holes, and when ringing through or after rain, a short circuit can occur, because the engine is below and the case is equipped with ventilation holes.

From a motor from a meat grinder, an aluminum pipe and an old thermos

In such a homemade, the thermos plays the role of engine protection, preserving it from scraps of grass and partially moisture, and an electric motor from a meat grinder has small size and high power.

The handle can be made from plywood or any other suitable material, as well as take a ready-made tool from some kind of garden tool.

The main difficulty is to bend the pipe correctly, because aluminum is a very delicate and brittle metal, so any mistake often leads to cracking or rupture of the pipe during its bending. Use a pipe bastard or fill the pipe with dry small sand and bend after warming up.

TOP of the best non.self.propelled braids

It is difficult for an ordinary buyer to choose a self.propelled model, even given the selection of the device by width width and other parameters.

After all, in addition to the information indicated on the model page, there is also what is difficult to describe in numbers, that is, the reliability and convenience of the device.

One of the sources of such information will be our article, in which we described in detail all the most popular devices of this type.

Is it possible to cut wet grass?

The peculiarity of the wet grass is that it is much softer than fresh or dry, so it manages to react to the effect of a knife. the mower does not cut, but chews it.

After passing the lawn mower, the surface of the lawn with wet grass looks extremely unaesthetic, so any battery lawn mowers are not suitable for such use.

This does not indicate their inferiority or inefficiency, because the devices of other types are also not suitable for cutting wet grass.

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).

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.

Repair of malfunctions of an electric mower

Long grass that has wound on them can be led to jamming knives. For repair, you need to turn off the device from the network and twist the cylinder in the opposite direction.

If the electrical device is silent, the drive belt breaks the resulting result of wear: it can be stretched or broken off. This means that you can not do without replacement, for which you need to remove the protective cover.

The new belt is first installed on a small gear of an electric device, then, put on a large pulley, and turning it on.

To replace the power cable of this electrical device, it is necessary to de.energize the device and unscrew the lid.

To disconnect the cord, insert the hexagonal key into the hole with the wires, freeing the clamp.

The new power cord is installed in the reverse order.

The reason may also be hidden in a faulty power switch, which is simply replaced by a new.

Repair of an unexpectedly stopped electric engine

If the motor worked, but suddenly stalled, you need to check the crankshaft and the piston. perhaps they were overwhelmed. This is due to the absence of oil in the crankcase. It is better to contact specialists with this breakdown, as in the case when the electric motor of the lawn mower requires repair.

For non.precise operations of the lawn mower, the owner must conduct its regular maintenance after the end of the working season, t.e. Before her premises for winter storage. This will cost cheaper than repair or buying a new electrical device.

Among the main measures that ensure the reliable operation of an electric mower is clean. The mowed grass accumulated under the neckline causes erosion of metal parts. The compressor or blunting will help to remove the remaining weeds.

The electric motor of the mowing is air cooling, therefore, it also requires a cleanliness that is a key to effective functioning. Suitable for cleaning the cooling ribs soft brush and compressed air.

Timely oil replacement specified in the use guide will become the key to prolonged trouble.free work, as well as the periodic cleansing of the air filter.

In the presence of a certain experience, it is easy to repair the lawn mowers with your own hands. The video below will help in this.
