Other homemade options

Thanks to the economical and reliable engine, the grass trimmer is the basis for many other homemade products as well. Below we will briefly describe the possible options and provide video instructions for their implementation.

How to Build a Grass Trimmer Motor Bike?

Despite the fact that technical progress does not stand still, and every year we are pleased with new vehicles, today there are still people who like to do something unusual and original on their own. Who could have imagined at the end of the twentieth century that in the twenty-first century an ordinary bicycle would be supplemented by a motor from a brushcutter.

Before disassembling the grass trimmer and starting to design a bike with a motor from a brushcutter, you should pay special attention to the engine power. After all, it will depend on the power how long you can ride on the upgraded bike. Ideally, the engine power should be at least 2 horsepower. In the event that you install a lower engine power, a homemade bike may not move even from a place.

Assembling the cultivator

If there is a summer cottage or just a plot of land, then the cultivator will help facilitate soil cultivation. Traditionally, a hoe is used for these purposes, but working with it takes a lot of time and effort. Using a cultivator will reduce labor costs and the whole process will take less time. Factory-made equipment is expensive, therefore, with limited funds, the question of self-assembly of the cultivator arises. For this, both petrol grass trimmers and electric scythes are suitable.

Велосипед з таймера, як будувати самостійно, крок за кроком

To create the simplest piece of equipment, you should stock up on the following tools and materials:

  • angle grinder with a set of discs (suitable diameter. 125 mm) for metal;
  • drill with drills of various diameters;
  • welding machine;
  • electrodes;
  • jigsaw or hacksaw for metal;
  • emery machine with two abrasive wheels of different grain size;
  • a functioning gasoline trimmer;
  • pitchfork;
  • a steel tube suitable in diameter for the brushcutter shaft;
  • hand tools: wrenches, hammer, pliers, punch, tape measure and marker;
  • sheet of metal with a thickness of 3 to 5 mm and dimensions of at least 1010 cm.

The manufacturing process begins with the working part. For this purpose, the curved rods of the garden pitchfork will serve. Their recommended length is from 10 to 15 cm. this is enough to loosen the soil.

The working nozzle is manufactured in the following sequence:

  • the forks are flattened to a width of 1 cm;
  • on emery, using a circle with a fine abrasive, cutters are sharpened;
  • using a jigsaw, cut out a circle with a diameter of 10 cm from the metal;
  • process it on an emery machine until it reaches an almost ideal shape;
  • at regular intervals, prepared cutters are welded to the metal circle (the recommended amount is 3).

With more than 3 pieces, the number of cutters, the load on the equipment greatly increases.

The recommended power of the gasoline engine should be two horsepower (approximately 1.5 kW) or more.

The next step is to attach the weeding cutter to the grass trimmer. The process is greatly simplified in the presence of a reverse thread located at the end of the brushcutter shaft, onto which the manufactured working part is simply screwed on. To do this, a tube with a nut is pre-welded to the mill.

With the locksmith experience and skills of a welder, converting a grass trimmer into a cultivator is quite simple. The financial costs are insignificant. If an electric scythe is used in the work, then you will need to think about an extension cord so that it reaches throughout the treated area.

Making a snowmobile for children

The grass trimmer can also be converted into a snowmobile. The process consists of installing the engine on a structure equipped with skis. Due to the insufficient power of the motors available on the brushcutters, the created independent technique is capable of transporting only a relatively small weight. She also moves on relatively flat terrain. Such a homemade product will serve as an interesting and useful toy for children.

The snowmobile is driven by a screw or chain drive.

The videos below show some possible options for homemade equipment:

DIYers have come up with many different ways to adapt the motor from a grass trimmer to a snowmobile. Here, the restrictions are associated with personal imagination and the existing list of unnecessary devices and techniques that can be used to create homemade snowmobiles.

DIY lawn mower

The lawn mower makes it easier to care for ornamental grassy plantings, and also speeds up the work when there are large areas that need to be worked. On the market for such equipment, there are many ready-made, easy-to-use models, 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 grass 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, make a hole for the grass trimmer bar and attachments for it;
  • make a knife or choose a suitable ready-made version;
  • then fix the brushcutter on the trolley;
  • install a knife;
  • to protect from the cut grass flying in different directions, the casing is mounted on the back of the trolley;
  • 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 saw for wood). 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 do not use an old brushcutter, but only the engine from the grass trimmer and the control unit for it. In this case, you will need to make handles for the trolley and fix all structural details 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.

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 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 grass trimmer, bicycle and a small set of tools will require time and patience from the performer.

Scooter

In addition to the bike, the scooter engine is also installed on the scooter. The assembly principle is similar to the creation of a motorbike, only this takes into account the design features of the scooter.

The video below shows an airplane, the engine of which is taken from a gasoline scythe for grass.

Having at your disposal an old worker and an unnecessary grass trimmer, you can make various technical devices with your own hands, not only those discussed above. Your own imagination will tell you different options. But, creating any device, you should remember that it would be safe for others and people using it.

The sequence of the 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.

Self-assembly of the engine

After assembling and installing the drive, the operator can proceed with the installation of the motor. For safety reasons, the internal combustion engine from the brushcutter must be mounted on the moped using an additional suspension made of metal. The fastener itself should resemble a frame welded from steel channels and corners.

The shape and dimensions of the frame must correspond to the dimensions of the motor used. There are different ways to attach the bike rack to the bike frame. If in the future the motor will not be removed from the moped, then the internal combustion engine mount can be welded to the device. If, in the future, the motor will be removed for its subsequent installation back on the grass trimmer, then a pair of bolted connections will be suitable for attaching it to the moped.

Installing the brake system.

A homemade bicycle with a lawnmower engine must be equipped with a brake system. To make it, you will need to use a pair of brake discs installed one at a time on the drive and driven wheel. To control the brakes, the discs using metal cables must be connected to the levers installed on the handles of the standard handle.

In addition to installing the brakes, the operator will also need to replace the standard tires on the moped wheels. Not only the cross-country ability of a self-propelled bike depends on this, but also the safety of the owner when driving off-road.

Assembling the drive for a moped

For self-propelled movement, the scooter must be equipped with a belt that receives torque from the engine and transmits it to the drive wheel.

To assemble a quality drive for homemade products, the operator needs to use:

  • driven pulley. this unit should be slightly smaller in diameter from the bicycle wheel rim;
  • drive pulley. during assembly, this element must be attached to the motor from the grass trimmer;
  • steel suspension. it will be used to attach the motor to the frame of a homemade moped.

To assemble the drive, you also need to assemble the gearbox. Once the pulleys have been mounted on the bike, the manufacturer will be able to fit the belt with the appropriate length and width.

Bicycle with a motor from a grass trimmer. production of elements and self-assembly of a moped

The modern grass trimmer is much more than just a garden tool. The high power of most brushcutters makes it possible to use them as a basis for assembling all kinds of homemade products, not the least of which is a bicycle with an engine from a grass trimmer. This self-propelled device stands out for its simplicity of the device, high traction parameters, and ease of maintenance. The relatively low consumption of a fuel moped makes it possible to cover considerable distances on it, and a high suitability for repair. independently eliminate almost any malfunctions of a homemade product.

Grass trimmer bike. what to look for before assembling?

Before you start assembling a motorbike with your own hands from a lawn mower, you will need to choose an engine, which will become the basis for homemade products. It is the power of the internal combustion engine that directly affects the traction characteristics and endurance of the device.

Homemade TRIMMER Bike. 62cc. Motorised Bike

In practice, homemade products, equipped with engines from trimmers with a capacity of 3 liters or more, have shown themselves best. from. and higher. Each such scooter with a motor is capable of transporting 1 adult with hand luggage, while having an additional supply of torque.

It is strongly not recommended to collect homemade products based on electric motors from trimmers. This is due to the low power reserve of such motors, as well as their instability in front of bad weather conditions. If there is no other way out, and the manufacturer only has an electric motor at hand, then when installing the motor, special attention should be paid to protecting it from external factors: moisture, dust, debris. With the further operation of the scooter with an electric motor from the grass trimmer, you will need to take frequent breaks to cool the engine. Otherwise, the engine will quickly fail.

Having dealt with the motor, you need to move on to the bike frame. It will need to be equipped with an additional platform on which the engine and fuel tank will be mounted. In this case, the latter should be located above the engine from the grass trimmer so that the fuel flows to the power unit in a natural way.

It is very important that homemade bicycles with a grass trimmer motor are equipped with a comfortable handlebar, on the handles of which you can move all the switches you need to work. This will simplify the operation of the homemade product when traveling at high speed.

How to make a moped with a motor from a brushcutter?

Assembling a homemade grass trimmer begins with studying the detailed drawings. The diagrams should indicate the dimensions of the parts used, as well as the sequence and methods of their installation into the general device of the moped.

Next, you need to prepare equipment and parts.

  • motor driven;
  • reducer;
  • brake system;
  • welding machine;
  • angle grinder;
  • set of bolted connections;
  • set of wrenches and screwdrivers.

The further procedure for assembling a homemade moped from a grass trimmer must be divided into several stages. Each of them must be treated with special responsibility, since not only the quality of the device depends on this, but also the safety of the operator during its operation.

Rules for operating a homemade moped

To extend the life of a moped with a grass trimmer motor, its owner needs to adhere to a number of important rules.

  • timely replacement of consumables. if you do not change the air filter and other elements of the moped for a long time, then its important mechanisms will begin to work under increased load. This will lead to more difficult homemade breakdown:
  • use high-quality gasoline and engine oil for refueling. if you pour low-quality gasoline into the fuel tank of a moped, then the bike owner will soon be faced with the need to replace the engine’s CPG;
  • lubricate the used gearbox in time. this will prevent the mechanism from operating under high loads;
  • mix gasoline and oil strictly in the proportion indicated by the grass trimmer manufacturer. if you add more oil than indicated in the instructions, this will lead to the engine spark plug being flooded;
  • regularly check the condition of the fasteners. bolts that are not fully tightened threaten not only the engine fall, but also injury to the owner;
  • paint scratches and chips immediately after they appear on the frame. this will prevent further corrosion of the moped frame;
  • do not allow the engine to overheat from the grass trimmer. with frequent use of the moped, you need to take breaks. At the same time, if the bike is used in hot weather, then its motor must be allowed to cool down every 15 minutes of riding. If it is cool and windy outside, the number of breaks can be reduced to 1 time for every 25-30 minutes of driving;
  • timely change the tires on the wheels of the moped from the grass trimmer. in winter, rubber with spikes must be installed on the wheels of homemade products. This will prevent wheel slippage and increase the safety when using the bike.

Also, the owner of a bike with a grass trimmer motor will need to monitor the weight of the cargo transported on the homemade product. If the luggage is too heavy, it can lead to overheating and serious damage to the engine, as well as other mechanisms of the device.

Check in work

We start the engine. By adjusting the idle speed, we set the output voltage at the generator output in the region of 220 V.

We connect various loads. Voltage sag is not significant.

I can’t say about the power of the installation itself, but I think it is quite possible to take 200-300 watts from it.

Converting a grass 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.

bike, grass, trimmer, motor

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

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.

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 gasoline grass trimmers are being redesigned for this purpose.

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.

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 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 grass trimmer, bicycle and a small set of tools will require time and patience from the performer.

Homemade snow blower

There are many options for creating snow removal equipment based on a grass trimmer. The simplest way to upgrade is to replace the knife with a rotor. Such a snow blower works like a shovel, but at the same time it is simply moved through the snow: the device rakes it and carries it to the side.

To implement the planned alteration, you will need the following materials and tools:

bike, grass, trimmer, motor
  • a lawn mower with a straight bar, at the end of which a gearbox is installed;
  • a metal keg, even a beer keg, for example, from a drink Baltika;
  • milling cutter for grass trimmer with many teeth (used for mowing dense thickets of grass);
  • drill with drills;
  • angle grinder and welding machine.

Instead of a barrel, you can use a thin sheet of metal (tin) 1.5 mm thick.

The assembly process of the snow blower is performed in the following sequence:

  • cut in a circle, departing from the bottom of 15 cm, a barrel;
  • make a hole in the bottom for the brushcutter gearbox and drill 3 more small holes to fix its shield;
  • a 10 by 10 cm square is cut from the side to throw snow through it;
  • a third of the open front part of the barrel is closed with a piece of metal (tin), while the hole for the ejection should be located along the central mowing line of the damper;
  • make a rotor;
  • make a deflector that will direct the ejected snow in the right direction;
  • weld it to the body at the location of the hole for the ejection of the snow mass;
  • attach the blade from below;
  • install a brushcutter gearbox and secure with bolts;
  • put the rotor like a simple working knife.
  • a strip is cut out of metal, the width of which is 15 cm and the length is 30 cm;
  • slightly bend the workpiece;
  • 10 cm high sides are welded from the long sides so that the snow does not scatter at the exit.

The rotor is made in the following sequence:

  • cut rectangular strips with dimensions of 25 by 10 cm from a metal sheet;
  • cut and grind the plates in the shape of the blades;
  • weld them crosswise to the disc from the brushcutter.

A spatula is made from the remains of the material. To do this, use a piece of tin 30 by 40 cm.Along the long sides, the edges are bent to form a two-centimeter side.

A self-made snow blower should be used at full throttle. this will extend the life of the device, because frequent pressing on the gas leads to engine breakdown. It is difficult to weld thin metal because it can easily burn through it. Therefore, the work must be done by an experienced welder.

The sequence of the 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.

Materials needed:

Actually, there is nothing complicated in this design, you need to make a frame, fix the grass trimmer motor and generator on it, put the pulleys and put on the belt. Everything is shown in detail on

We connect to the generator. voltmeter and sockets.

The result is a homemade gas generator with your own hands. The approximate power of the generator is approximately 300 watts. This is enough to connect several LED lights, charge phones and a laptop.

The process of making a homemade gasoline generator and testing it is shown in this
