How to make a lawn mower from a trimmer

Required materials and tools

A device such as a do-it-yourself electric mower is not a daily necessity. But the presence of such a tool at home will significantly save labor costs when mowing grass. Very simple lawn mowers can even be made from an electric motor. They include the same details and functionality as factory counterparts.

Electric lawn mowers include:

• an electric motor or drive mechanism with which the blade attachments rotate;
• the base of the frame on which all the details of the mechanism will be held;
• protective shield;
• a handle with which the mechanism is controlled;
• blade knives;
• 2-4 wheels;
• button for turning the mechanism on and off;
• power cord;
• container for collecting grass or removing it.

It is necessary to constantly observe the safety of work, and therefore it is necessary to install an element of emergency and automatic shutdown of the electric mower.

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

DIY Electric Lawn Mower Repair Tips

Even the highest quality electric lawn mower models are prone to breakdowns, and the operation of budget models can be malfunctioning all the time. In most cases, the failure of the tool is associated with minor problems that you can fix yourself by examining the problem in detail.

Gasoline Lawn Mowers

First of all, this option is optimal for owners of very large plots. The fact is that gasoline models have more power and functionality. The crankshaft of an internal combustion engine acts here as a working element.

Benefits:

• The petrol model will give you complete freedom of action! You do not have to untangle the wire and drag it around the site. You don’t need a socket either. Complete autonomy and ease of management. We can say that this is not just a lawn mower, but a full-fledged robot that will do all the work for you.

Disadvantages:

• The most significant disadvantage of such models is a lot of noise.
• Another significant drawback is exhaust fumes. Not everyone wants to breathe gasoline fumes in the fresh air.

Self-propelled lawn mowers

This technique is equipped with a gasoline or electric engine. It is a trolley that moves with four wheels. In the upper part there is a power unit, and in the lower part there is a rotating knife.

To know how to choose the right self-propelled lawnmower, it is recommended to find out what features are inherent in it. Of the minuses, one can single out a high degree of noise, as well as insecurity during operation. Most often these lawn mowers are used to care for large areas of lawns.

The pluses include:

no need to push the technique in the process of mowing lawns, spending energy; convenience and ease of use.

It is important to know! Before mowing the lawn with a self-propelled lawn mower, it is recommended to clear the area of ​​solid objects.

Manual (mechanical) lawn mowers

This category of lawn mowers is practically no longer available for sale due to its outdated technology. The essence of the operation of such a device is that it is set in motion by a drum with knives due to the muscular strength of the gardener. Of course, only a person with good physical shape can work with such a unit.

Benefits:

• The advantage of such tools is their almost silent operation.

Disadvantages:

• No engine, which complicates inventory management and decreases productivity.

Cons of a lawn mower

The site should be flat with a drop of no more than 10 degrees. For slopes, special machines with a two-stroke engine are chosen. It is necessary to remove stones, branches, debris on the way of equipment. they disable the knives. Overgrown grass, tough weed interferes.

It is impossible to mow neatly flush with the path or flower bed. To remove grass missed by knives, pick up a garden shears or a trimmer. A lawn mower is more expensive than a trimmer.

Hand lawn mowers

This type of lawn mower has a classification:

• machine;
• trimmers;
• mechanical.

Mechanical lawn mowers are considered the cheapest option, since they are not equipped with a power unit. With the help of hand lawnmowers, you can only care for lawns that have an even terrain, where there are no plants with thick and woody stems.

These handheld devices have a fairly simple structure:

• several gears;
• cutting drum;
• wheels;
• knife (fixed).

Also, the hand lawn mower is safe in operation, economical and light in weight.

Which lawn mower is better?

It is important to consider a number of factors here. And in addition to the type of engine, there are other structural components that are of great importance when buying:

How to make a grass cutter DIY at home | lawnmower

Power. The higher it is, the better for management. However, you should not choose a super powerful machine for a small lawn. In this case, it will be more expedient and cheaper to purchase a conventional trimmer.

At the same time, do not save when buying a machine for working on a large lawn area. Otherwise, there is a high probability of quick breakage of a low-power tool.

Body material. Currently, there are steel, plastic and aluminum lawn mowers on the market. The most preferred option is the aluminum case.

The volume and type of the collection box. The frequency of cleaning the collection box depends on the volume. Choose the best option for your lawn area.

From the washing machine

To create a lawn mower from an old washing machine, you will need:

• engine from her;
• steel knives;
• wheels;
• pipe that will become the basis for the handle;
• electric drive;
• fork;
• switch.

The knives should be made of steel that is 2 or 3 mm thick and half a meter long. The cutting part bends down a little, which allows you to protect the shaft from various objects falling into it. The handle is created from a tube so that the device is comfortable to hold. It is attached to the frame by welding.

On the chassis from the trolley, a platform is mounted, previously made from a sheet. Then a hole is made for the motor shaft. A steel grill is installed on the front as protection. The upper and lower parts of it are screwed with bolts, to which the wire is attached.

The grill of the device allows you to create a gap for the knife. The motor is attached with the shaft through the hole. A previously sharpened knife is mounted on it, and a hole is made in the middle.

The knife should be balanced and centered. The motor is covered with a shroud for protection. Considering that it needs to cool when it is running, there should also be holes in the casing. It is connected to the wiring, which is fixed to the body. The metal handle should be wrapped with a rubber cover in order to protect against possible electric shock.

Device

To make a lawn mower for your grass, you need to have a specific list of parts on hand. The main engine will be from any device that is not used for some reason. The motors from small devices are unlikely to withstand the heavy loads that are inevitable when mowing grass. They overheat and break down too quickly. And there is no point in repairing them. They often try to use motors from vacuum cleaners, but they definitely will not cope with such a job.

It is best to use a motor with a power of 1 kW / h or more for the lawn mower.

The next element that will be needed is a knife. It must be made of strong and thickest steel. There may be several of them. A self-sharpening disc may also work. This is the simplest and most durable option.

If we talk about a handle for a lawn mower, then it can be taken from an unnecessary wheelbarrow or an old stroller. In addition, we need a metal frame on which all the elements of the device will be attached. It is important that there are no traces of corrosion on it, and that all parts are intact and not damaged.

If it is not possible to find a suitable frame, you can make it yourself from metal pipes.

Also, to create a lawn mower, you will need a power cord, preferably a longer one. But this is in case we are interested in an electric home-made mower. You will also need wheels with a small diameter. For the unimpeded movement of the self-propelled mower on the site, it will be enough wheels with a radius of at least 10 centimeters.

You will also need a special protective cover that is fixed around the cutters. It can be made from sheet metal or you can choose a suitable ready-made solution in size. You will also need a protective cover to ensure the safety of the person operating the mower. In addition, it will keep the cutters from stones. Other parts may be added to the mower, depending on the required design features. For example, a grass catcher will allow you not to leave the grass on the territory, but to collect it in a special container. He might be:

• combined;
• tissue;
• plastic.

Fabric solutions are very compact and lightweight, but require washing from time to time. When the cells begin to clog at the mesh, a kind of airlock is created, which may be the cause of overheating of the motor.

Plastic counterparts are made using high quality materials. If a foreign object accidentally falls into them, this will not disrupt the operation of the device in any way. The plastic container is easy to clean.

Combined solutions usually come with expensive lawn mowers and therefore offer the benefits of both capacity categories.

Also, the device can be equipped with elements of a gasoline trimmer, if we are interested in a gasoline mower or it is made from a trimmer.

From an old vacuum cleaner

Another option for creating a lawn mower is the transformation of a vacuum cleaner. First you need to make a cutter. If possible, a polymer type thread should be used. It needs to be attached to a steel segment, in the middle of which there is a hole. Now a knife is made from the saw. By the way, if the steel is very hard, then it should be softened.

Now the workpiece should be very hot, and then let it cool. When the knife is made, it needs to be heated again and cooled very quickly. The torch should be up to half a meter long. The cutting edge is usually sharpened at a 60 degree angle. The edges are made along the knife edges. The gross opening must be as accurate as possible, as the cutters have to be balanced in the future.

All parts of the structure must be fixed as efficiently as possible. So that the cutter does not accidentally deform after hitting the stones, it must be assembled. To the base in the center, steel knives should be attached from 2 sides with bolts. Upon impact, the knife will only turn and the risk of damage will be minimal.

A hole is made in the plate so that there is an opportunity to put the motor. It is placed in the slot and clamped with a steel strip, then set across the slot and screwed in with screws. The part where the turbine is located is removed from the motor. The cutting element is installed there.

On the reverse side, the turbine is dismantled, and a tin fan is placed in its place. To protect the motor, a tin cover is attached to the plate. You can use the cover from the vacuum cleaner from which the engine was removed. A PCB plate with a motor is installed on a chassis with wheels. At the final stage, the handle should be attached to the device using the brackets on which the switch is fixed. Now the cables are connected to the motor and the button. At the end, they must be insulated and the system operability checked.

Training

So, before you start assembling the lawn mower, you will need to have the following items on hand:

• frame materials;
• wheels;
• pens;
• protective cover;
• engine;
• the frame where all the parts will be attached;
• knives;
• control elements. RCD, switch, cable with a plug for connection to a socket.

In addition, an important preparatory stage will be the creation of drawings and diagrams of the future design. This will help to maintain the correct location of all elements of the future structure and create the correct frame that can withstand the weight of all elements and will look beautiful from an aesthetic point of view.

Also, various parts can be added to the specified list, such as a chain or an adapter, if a self-propelled mower is made from a drill or chainsaw.

From a chainsaw

Can be converted into a chainsaw mower. We take the motor to be put on the cart. It is made like a frame from profile corners 2.5 by 2.5 centimeters. Its dimensions will be approximately 50 by 60 centimeters. Wheels are installed at the corners. You should also install the steering wheel and tire there.

A handle is made of the pipe, the height of which can be adjusted. A steering wheel, hose and cable are attached to it. The engine is now screwed onto the frame. The tire is secured using a hole in the gearbox. The casing fasteners are placed below. This is the future foundation of the mower. Now it remains to install the knives using welding. This is carried out on the star of the saw on a pre-installed length of pipe.

From the grinder

Making a good lawn mower is easy if you use a conventional grinder. The body of the device is made from a car rim. It should be cut into a couple of pieces. The cover is welded to one of them. A hole is made on the side, where the front of the mower will be located. A handle and wheels are attached to the body. Holes are made in the casing or. The device is fixed to the body using bolts. Also, a knife should be made of steel. Its edges should be well sharpened and set like a propeller.

The knife is attached to the Bulgarian shaft, after which the nut is tightened. At the final stage, it is screwed on with a screw installed in a nut. The switch on the device is fixed by means of a bar. We put a switch and a plug on the handle so that it is easy to connect an extension cord to it if necessary.

Mowing grass in a suburban area allows you to give the territory a well-groomed and pleasant look. But constantly doing this with a hand scythe is very inconvenient, not to mention a serious loss of time and effort. But it is not always possible to purchase a lawn mower. Then you can do it yourself. Let’s try to understand the intricacies and features of this process.

What can be done from a trimmer

What can you make from a trimmer yourself to make everyday work easier or for fun? Such a question arises if there is an old unnecessary device, or a technician is required for the operation, which, when manufactured at the factory, is much more expensive than a gasoline or electric scythe. In practice, folk craftsmen have implemented many options. The main ones are a motorbike, a snow blower, an ice ax, devices for cultivating a land plot and mowing lawns, a saw, and snowmobile equipment. To bring the idea to life, in each case you will need to use a certain set of tools and additional materials.

Motobur

The brushcutters can be converted into a motor-drill, which will also be used as an ice screw if necessary. As a result, construction work will be accelerated and will require less labor. With a motor-drill, they make recesses for the posts of fences, a foundation from piles and for the erection of other structures.

Both electric and petrol trimmers are being redesigned for this purpose.

Sequence of assembly of the structure

To independently assemble a bicycle with a gasoline engine, you will need, in addition to the materials and parts considered, also:

• controller;
• cable for adjusting the operation of the motor;
• fuse;
• welded exhaust pipe;
• sleeve;
• washers;
• bolts;
• chain tensioner.

The assembly of a motorbike is carried out according to the following algorithm:

• put an asterisk on the rear bicycle wheel;
• a clamp is used to fix the engine (with an asterisk on the shaft) on the frame behind the seat or on the trunk, if the design features of the bicycle allow, otherwise you will need to choose another convenient place for this purpose;
• put a chain on the sprockets of the wheel and motor;
• attach the tensioner;
• adjust the chain tension;
• fix the gas handle;
• stretch a cable from it to the engine;
• fix the fuel tank;
• mount the carburetor.

For the purpose of personal safety during the operation of the motorbike, the braking system is modernized, the tires of the wheels are changed for non-slip products, the integrity and stability in motion of the created structure are checked. After the entire structure is assembled, it is tested, having previously examined for imperfections.

It is recommended to give preference to disc brakes.

We make a motorbike

Home craftsmen managed to make a more practical vehicle out of an ordinary bicycle. they rearranged the engine from the brushcutter to it. At the same time, options are practically implemented with both a gasoline engine and an electric motor.

DIY lawn mower

The lawn mower makes it easier to care for ornamental grasslands, and also speeds up the work when there are large areas that need to be worked. There are many ready-made, easy-to-use models on the market for such equipment, but they are expensive, therefore not available to everyone. They also quickly fail in the presence of large weeds and stones on the site. Homemade products are much cheaper than factory counterparts, moreover, they are more practical to work with.

The components of the lawn mower design are:

• engine (gasoline or electric), which is the basis of the created mechanism;
• a frame designed to fix all parts of the device on it;
• casing for protection;
• knives;
• handles and wheels;
• unit of the control system of the created unit.

The recommended power of the engine used in operation is from 0.5 kW (slightly less than 1 horsepower), and the ideal power is 1 kW or more.

Craftsmen have invented many different ways of converting a trimmer into a lawn mower. The simplest option is presented on

A frame version of a homemade device is very common in practice. The tools and materials for the independent implementation of the project will be required the same as in the previous case. Plus you still need:

• plywood sheet (or metal 3-4 mm thick);
• metal corner 25×25 mm;
• 2 m pipes of different diameters.

The manufacturing process is as follows:

• a rectangular frame 50×60 cm is welded from the corner;
• wheels of the required size are installed in the corners, which can be taken even from old toys;
• on top of the frame, plywood cut to its size is fixed or metal is welded;

• in the center of the cart, a hole is made for the trimmer bar and fasteners for it;
• make a knife or choose a suitable ready-made version;
• then fix the brushcutter on the trolley;
• install a knife;
• mount the casing on the back of the cart to protect it from the cut grass flying in different directions;
• start testing the device.

Important! The diameter of the wheels is selected so that the knives do not reach the soil 5 centimeters.

There are many ways to make knives, and their shape (design) is radically different. In this case, various materials and old tools are used (for example, an old wood saw). The main principle is that the knives are well sharpened and balanced. this is necessary to prevent vibration of the equipment during operation.

It often happens that they use not an old brushcutter, but only the engine from the trimmer and the control unit for it. In this case, you will need to make handles for the trolley and fix all the details of the structure on the frame.

When assembling and operating the mower, be sure to follow safety precautions to avoid injury. You can also attach a bag to the machine to collect the mowed grass.

Converting a trimmer to a chainsaw

A gasoline brushcutter can also make a chainsaw. To translate the rationalization idea into reality, you will need old device models. All details will be taken from them. The video below shows the result.

Converting the trimmer into a gasoline saw consists in installing this part from the brushcutter instead of its own engine on it.

Required tools, materials and parts

An electric motor for a bicycle is powered by a battery, which, depending on the power of the unit (it is taken from 0.35-1.2 kW), lasts from 30 minutes to 2 hours.

Two- or four-stroke gasoline engines are used to redesign the bike. The latter option consumes less fuel and is less noisy during operation. The recommended power is from 1.5 HP, and the optimal variant is 2 HP. When using a motor with a lower parameter, the motorbike will barely ride or will not be able to move at all.

The rotational movement from the gasoline engine to the bicycle wheel occurs through the use of a belt or chain drive. Because of this, you will additionally need to make the following details:

• a metal suspension in the form of a frame with bumpers to secure the motor to the bike frame;
• driven and driven pulleys or sprockets for attachment to the engine and wheel, respectively.

From the point of view of practicality, the use of a chain drive is preferable to a belt drive, because the belt wears out faster, especially if it gets wet regularly.

To implement the project, you will need to select a suitable gearbox. After installing the pulleys, select the correct belt size.

The dimensions of the frame for the engine depend on its dimensions. The suspension itself is fixed to the motorbike frame:

• bolted connection;
• by welding.

The latter is the best in terms of strength if the welder is good. If the design of the bicycle frame allows, then the suspension is replaced with a yoke that secures the engine. This mounting option is more practical. The method of fixing the motor should be convenient, reliable and allow you to quickly remove it if necessary.

Doing all the work with your own hands in the presence of an old, functioning trimmer, a bicycle and a small set of tools will require time and patience from the performer.
