DIY Motorized Cultivator

Useful Tips

In order for your motor cultivator to work effectively enough and serve you for a long time, you need to take into account some expert advice.

  • If you could not find 1 powerful one, then you can use 2 low-power motors (no less than 1.5 kW each). They need to be fixed to the frame, and then a single system must be created from two separate elements. Also, do not forget to put a double-strand pulley on one of the engines, which will transmit torque to the pulley of the working shaft of the cultivator gearbox.
  • In order to properly and efficiently assemble a cultivator with your own hands, you must be guided by the drawings.
  • Due to the fact that the rear wheels are support wheels, they should be attached to the frame by means of an axle with bearings.

With a motor from a moped

a moped tiller is a tiller with a D-8 engine or with an Sh-50 engine. That is why for the full functioning of the structure, it is necessary to install an analog of the cooling system. Usually, for this, a tin vessel is soldered around the cylinder, which is designed to pour water into it.

Important: the water in the vessel must be changed regularly, make sure that the temperature of the cylinder does not exceed 100 degrees Celsius. That is, if you notice that the water has begun to boil away, then you need to suspend work, cool the engine and replace the fluid.

Also, the device must be equipped with a gearbox using a bicycle sprocket. The bottom of such a design will be a thrust, so the output shaft must be secured and reinforced with metal bushings, which must be tightly attached to the gearbox.

In addition, the tiller can be made from a snowplow, from a trimmer.

What elements are required for assembly?

If you decide to design a tiller yourself, then you need to prepare the following set of building blocks:

  • an internal combustion motor or engine;
  • gearbox. it is able to reduce speed and increase efforts on the working shaft;
  • the frame on which the equipment is mounted;
  • control handles.

It is these details that are the main ones. without them, it is impossible to make a machine for agricultural land cultivation at home. Therefore, before starting the manufacturing process, make sure that each of the items described above is present.

Manufacturing scheme

Many experts argue that you should design a gasoline-type tiller yourself and at home.


Before starting the production of a motor-cultivator, you should decide on what type of agricultural unit you will design: with an electric motor or with an internal combustion motor. It is important to remember the fact that a motor cultivator with an electric motor will be effective only if there is an energy supply system on the area to be cultivated. On the contrary, a device containing an internal combustion engine can be used in the field, since it runs on fuel, namely, gasoline.

Important: the maintenance of gasoline motor-cultivators will require a greater amount of financial resources, and it is also quite difficult to maintain them technically.

Another important nuance is the method of soil cultivation. There are cultivators that have wheels with a drive, as well as those units that are equipped with attachments (the latter can serve not only as tillers, but also as a means of transportation).

  • How to fix breakdowns yourself?

A motor-cultivator is an analogue of a mini-tractor, its kind. A motor-cultivator (popularly, this device is also called “tiller”) is designed for soil cultivation. This agricultural machinery is produced both in Russia and abroad, and therefore is widely represented on the market. However, it is worth noting the fact that the purchase of a motor-cultivator can cost a rather large amount. In this regard, many craftsmen with little knowledge of technology, as well as possessing some improvised materials, make a motor cultivator on their own at home.

From the chainsaw “Friendship”

Most often, home-made motor-cultivators designed for processing a small private area are made using a Druzhba chainsaw. The thing is that the manufacturing procedure itself is quite simple, and the Druzhba saw can be found in the household of many homeowners.

First of all, you should take care of the manufacture of the frame for the unit. Remember that the frame must be cubic. The engine from the chainsaw is placed and firmly attached to the upper corners of the designed frame, and the fuel tank is installed slightly lower, and the fasteners for it must be prepared in advance.

It is also imperative to use the vertical frame racks: they will accommodate the intermediate shaft supports.

Important: remember that the center of gravity of this design is above the wheels.

How to fix breakdowns yourself?

In the event that you make a mini-tractor with your own hands, you cannot avoid minor breakdowns and malfunctions. In this regard, their solution should be foreseen and considered.

  • So, in the event that you cannot start the engine, then most likely there is no spark. In this regard, it is necessary to replace the plug of the device. If this does not work, then try cleaning the filters (usually they are washed in gasoline).
  • If during the operation of the tiller you notice that its engine stalls quite often, then keep in mind that this may be due to broken spark plugs or poor fuel supply.
  • If during operation the unit emits a strange extraneous sound, then the reason most likely lies in the breakdown of one or more parts. In this case, you must immediately stop work, disassemble the motor and identify the breakdown. If this is ignored, the engine can jam.
  • If the engine makes a lot of noise and overheats quickly, then the reason for such a drawback may be that you are using poor quality fuel or you are overloading the device. Thus, it is necessary to suspend work for a while, give the unit “rest”, and also replace the fuel.

Additionally, there is all attachments, also homemade: a plow, a hiller, a potato digger and a trailer with wheels from Moskvich.

Overall, it turned out to be a great homemade tiller.!

From a drill

Annual work in the garden gives summer residents a lot of trouble and difficulties. To save time and effort, many craftsmen invent semi-automatic devices that provide effective soil and horticultural cultivation.

To create a compact email. cultivator with good KPIs (Key Performance Indicators), a construction drill can be used. This option is suitable for weeding potatoes and performing simple agricultural tasks.


Any work in the garden requires a lot of effort. To make the process comfortable, you should create a special seat. adapter.

Valley Oak Tool Electric Wheel Hoe Field Test

Power point.
Electric motor or internal combustion engine. The electric drive can be taken from an old ventilation system or an industrial compressor; such power plants have a decent resource and high reliability.

If you use an internal combustion engine (for example, from a moped), it must be forced to cool, so take care of installing a fan. The chainsaw motor has an advanced cooling system, so there is no overheating problem.

A must for any tiller or cultivator. The high speed of the output shaft of the engine (whether electric or gasoline) is too high, and the torque in the compact power units is not enough for tillage.

With the help of a reduction gear, the revolutions are reduced, and the force on the working shaft increases.

Frame and portal for attachments.

Control knobs.
In addition to the main function of holding the mechanism in the working position, the power plant controls are brought to the handles. The structure must be durable and comfortable.

If you decide to assemble a cultivator with your own hands, the drawings can be taken from technical literature or developed independently. By being tied to the finished project, you will be forced to look for exactly those components that the author of the design provided.

We offer for consideration two designs with a different concept:

How to make a tiller with your own hands. detailed manufacturing instructions in various ways, find out what you can make a tiller from in the review! (125 photo videos)

Farmers and summer residents know firsthand how much effort and time it takes to work on the ground. And when the area of ​​the latter exceeds the traditional 6 acres, then the volume of labor grows exponentially. And here is the time to use the tiller.

But what about those who cannot afford to purchase the appropriate unit, and if they can, then only Chinese-made, hinting at no upcoming breakdowns?

Everything is simple. you need to answer the question of how to make a mini-tiller with your own hands, so as not to buy a less powerful cultivator and not bother with cultivating the land for a long time?

Summary of the review:


A useful accessory for the cultivation device is the travel reducer. It is designed to reduce the speed of the cultivator, which is necessary to redirect power not to speed properties, but to torque or tractive effort.

It is easy to make such a product yourself using the following components:

  • Generator housing.
  • Rotor shaft.
  • Flange bearing.
  • Steel parts.
  • Screws.
  • Pulley.
  • Gear.

Before starting work, you need to carry out several calculations. The role of the generator can be played by a part from the domestic Ural motorcycle. The main thing is that it is powerful and demonstrates stable torque.

The next stage involves the arrangement of the drive shaft on the basis of shells of two bearings, which will run the gear. Flange bearings are placed on the opposite side of the gearbox, and a metal washer is left inside.

The gear is fixed on the driven shaft, and at the end of the work, the pulley with the driven shaft is fixed. To do this, use a spring nut and washers.

After completing the installation work, the creeper must be checked by connecting the unit with the wheels to the coupling. If you do everything correctly, after starting the device, the wheels will spin more slowly, and the unit itself will be pressed to the ground.

From an old bike

An equally interesting home-made product is a hand-held cultivator made from a bicycle. To make such a device, you need to prepare a metal pipe, a frame and a bicycle wheel. You will also need metal blanks, steel strips, a drill, an angle grinder and a cultivator head.

Installation work consists of the following stages:

  • The cultivator head is attached to the bicycle frame. A crossbar and handles are made of a metal pipe. They are connected with bolts.
  • Then locknuts are taken. They will be needed to fix the wheel to the frame.
  • After performing such actions, the mechanism can be considered ready. To such a cultivator, you can attach a plow and related accessories that will make it more functional.

From trimmer

There are different attachments for the lawn mower that turn it into a potato digger, furrowing or plowing device. Homemade cultivators based on a trimmer are especially in demand for difficult-to-reach conditions where it is impossible to work with a large tiller with a trailer. The best option is a hand-held device called the Hedgehog. Having collected simple details and elements, “Hedgehogs” can be made by yourself. All that is required is a U-shaped bracket with holes, a shaft, a shank and spike wheels.

In order for the device to move normally around the garden, it must be equipped with good wheels. To do this, you can take old pancakes and provide them with metal spikes. The pins are made of cone-shaped fittings. Finished cutting elements are fixed on the axis, then it is inserted into the bracket and fixed on both sides.

A fastener is welded to the ends of the staple and inserted into the handle. It remains to check the unit for faults, eliminate them (if any) and start weeding the rows.

Of angle grinder

The option of a homemade mini-cultivator from an angle grinder does not differ in high productivity, but it perfectly solves the problem of weeding a small area with light soil. The angle grinder in this homemade invention acts as an electric drive. The rest of the units and parts can be taken from the old non-working cultivator.

See also  How To Make A Cultivator For A Tiller

An angle grinder is fixed to a frame created from improvised or taken from an old frame, as well as an extension cord on a reel for connecting to a power source.

After assembling the main elements, the machine can be tested. If done correctly, the cutters will produce up to 300 rpm.

Necessary materials

Among the materials that will be needed in order to manufacture any equipment presented in the list, first of all, there should be profiles of all types and steel sheets.

Metal pipes of at least three diameters will allow you to assemble strong and lightweight structures, make long handles, without fear of seriously shifting the center of gravity.

With the help of corners and channels, you can assemble excellent frames, in which there are initially niches for attaching various parts and parts. Also, for work you will need an angle grinder, a welding machine and a drill. Without the quiet, most popular tools, it will not be possible to assemble a single product.

From trimmer

Another way to use a technique with a low-power engine is a homemade cultivator from a trimmer. Such a product is perfect for fast processing of a small area, and it is very easy to make it from scrap materials. To do this, it is enough to make a cutter that will be attached to the trimmer shaft.

The milling cutter can be made from fork teeth, bent in the desired shape, fixed on a base. a nickle with a diameter of about 10 centimeters. The base should be perfectly round, with the mounting hole located exactly in the middle.

The pitchfork teeth, sharpened and pre-flattened to a width of one centimeter, are attached to the base with several bolts in a circle. The finished cutter copes well with loose soil at shallow depths.


One of the most practical and budgetary solutions for plots is a homemade electric cultivator. A reduction gear must be connected to the electric motor, which is already fixed on the base. It can be purchased or used as a second-hand.

Angles are welded to the crankcase of this gearbox, to which the wheel axles are welded. The wheels should not be small, as in this case they will be buried in the ground. The handles can be made of two, slightly curved pipes, between which a jumper is installed.

As a shaft, you can use a scrap chiseled on a machine, which is inserted into the place of the reducer sleeve. It is firmly and securely fixed, after which cutters can be welded to it. The cutters, in turn, can be made from car springs. they are very strong and will last a long time.

From the bike

A homemade bicycle hand-held cultivator is a great and cheap way to deal with weeds that have infested your garden and interfere with the growth of beneficial plants and crops. Making a hand cultivator with your own hands is easy, even at home.

With just a single mid-wheel bike frame and a high-carbon steel strip. To make a strong and reliable cultivator structure, you need to install the rear wheel on the frame and fix it well.

If the frame is turned over, the pipe in which the saddle is mounted will be directed end down. It is here that the plane cutter itself is installed on a tripod, which is welded exactly in the middle of the metal strip.

How to Make Powerful Tiller Machine at Home

The other part of the frame, the one where the carriage is located. now it is at the top, is equipped with long handles with a crossbar and an emphasis, which are attached to the frame by welding in two places, so that force can be applied to it while working with the tool, at the same time, without breaking its parts and connections.

Important tips and tricks

When starting to manufacture attachments and other implements intended for land cultivation, it is necessary to take into account some of the features of the production of products. If you personally assembled and run a cultivator or hiller, it will be impossible for you to guess how it will behave on the ground during work.

Especially if a tractor equipped with a homemade product has to work on different soils. Thus, a home-made cultivator for the T 25 may be too light, since it was assembled according to the scheme for the T 16 model, which has a lower engine power.

The same applies to equipment such as a home-made cultivator on the T 40. although this tractor has a lot of power, it will not be advisable to put large equipment on it.

The work will go much more productive if the cultivator is not wider than the rear axle of the tractor, and in length is not more than the width of the rear wheel.

In this case, he will be able to process a larger area, in a short time, with the same quality of execution robots.

From a Chinese chainsaw

One of the most successful inventions and a good example of how you can reuse old equipment is a homemade cultivator made from a Chinese chainsaw. Such a product will outwardly resemble a miniature tiller, since their designs will not differ much.

The frame of the product is a cube made of metal corners with an approximate size of 3232 centimeters. The engine must be secured to the upper cross member of this structure. The fuel tank must be installed slightly lower, on the brackets.

On the front vertical struts of the frame, it is necessary to install fasteners for the intermediate shaft. Supports for the bearings of the travel shaft are attached to the longitudinal corners of the frame. The result is a mechanism whose center of gravity is exactly above the supporting surface.

The weight of the product can be increased with the help of a load, moreover, by loading the mechanism from the front, you will not shift its center of gravity. The control handles are best made of a pipe with a diameter of at least 30 millimeters, using a cross-bar for greater structural rigidity.

It is best to strengthen them to the frame in four places. You can use any wheels for the mechanism, but rollers covered with a layer of rubber are best suited.

For mini tractor

To make a homemade cultivator for a mini-tractor or for a tiller with your own hands, you need metal plates, square, 1515 centimeters in size, rectangular. 254 centimeters and a steel pipe. You need to start making a cultivator with cutters.

In order for the cutters to be reliable and suitable for processing all types of soil, and not only loose chernozem, they need to be assembled with bolts. holes need to be drilled in the blanks, the number of which depends on the size of the metal strips, which will serve as blades.

The longer their length, the more holes are needed in order to securely fix them. Further, the strips are fixed to the workpieces, overlapping each other in a circle, and clamped with bolts.

Welding can also be used for these joints, but in this case they will not be strong enough, and repair and replacement of knives will be difficult. Welding is used here to connect the cutters together. For this, holes are made in the workpieces, the diameter of which must correspond to the outer diameter of the pipe.

The cutters are put on over it and fixed with tacks, or short seams. This product can now be put on the shaft of a mini tractor and used for its intended purpose.

Homemade motor cultivator

Many land owners know that cultivating the soil with hand tools takes a lot of time and effort. That is why mechanical devices are becoming more and more popular. But since quality devices are quite expensive, many landowners create such devices with their own hands. If you have a welding machine and some materials, it is quite simple to create a cultivator if the diagram of such a device has been created in advance.

How to make a cultivator from available materials

Before starting work, it is worth understanding the types of mechanisms that are designed to cultivate the land. By the type of the power mechanism installed in the unit, they are divided into products with an electric motor, as well as with an internal combustion engine. The first type of mechanisms should be chosen only if there is power supply on the site.

All designs with an internal combustion engine can be used on any site, as they run on gasoline. It is worth remembering that when using them, you need to spend more money, but at the same time they are more effective. It should be remembered that their maintenance is more complicated.

Also, motor cultivators differ in the methods of soil cultivation. Some products are equipped with driven wheels, while others are equipped with attachments that simultaneously serve as a means of movement and a tool for working the land. In the first case, two gearboxes are used. The first is necessary to move the device at a certain speed. The second one rotates the attachment.

It is worth noting that there are also tillers in which the wheels are not driving, but are installed as a support on the ground, thanks to these elements, the movement of the unit is simplified. In this case, the movement of the unit occurs due to the rotation of the attachment. It is worth noting that when using mechanisms without driving wheels, you have to spend more effort to keep a homemade cultivator on a given trajectory. That is why many land owners create cultivators with driven wheels, which makes the process of soil cultivation easier.

The cultivator wheels allow you to more effectively control the depth of the attachment in the ground. It is worth remembering that products with one drive axle have several advantages. For example, you can put wheels on an axle, and a plow behind them. Also, instead of wheels, you can attach volumetric cutters for loosening. It is worth remembering that a creeper must be installed on the cultivator. Such a device helps with wheel slip, as well as when working on heavy soils.

Components of a motor-cultivator

Cultivators consist of the following elements:

  • Power point. As which can be installed an electric motor or internal combustion engine. The electric drive can be disconnected from the old ventilation system or the motor of an industrial compressor can be used. If you choose an internal combustion engine, you can use an old moped. But it is worth remembering that in this case it is necessary to create a cooling system. When removing the gasoline engine from the chainsaw, this problem does not arise.
  • Reducer (creeper). This element is required when creating any motor cultivator. This is because the speed of the motor output shaft is too high and the torque in small motors is not high enough for soil cultivation. By installing a reduction gear, the speed is reduced, which contributes to an increase in the force on the working shaft.
  • Frame. When creating a frame for a motor cultivator, it is worth remembering that even if it is created for a single purpose, it is worth installing a bracket on it. It can be used to attach various attachments.
  • Pens. With their help, the device is controlled. All controls for the cultivator should be located on the handles. When creating handles, it is worth remembering that they must be durable and comfortable enough.

Drawings for a homemade cultivator can be taken from technical literature or created based on factory models. If you are looking for ready-made drawings, it is worth remembering that when using them, you will have to look for certain components for a future design. Before you make a motor cultivator from a saw with your own hands, it is worth considering the design of ready-made products in order to understand exactly how such designs work.

How to make an electric motor cultivator

Anyone who is even a little familiar with the principle of operation of such equipment can make an electric motor cultivator.

To work, you need the following details:

  • the motor from the grinder;
  • metal pipes;
  • corners;
  • wheels with axles;
  • screw;
  • scrap.

To create an electric cultivator, you will need tools such as a welding machine, a sledgehammer and a set of keys. Also, pliers and a hammer will be used in the process. The creation of a motor cultivator is as follows:

  • First, 2 corners are screwed to the metal housing of the gearbox.
  • After that, you need to bend the ends of the two tubes to create handles. The pipes must then be welded to the corners.
  • Then axles for wheels are welded to the corners. When choosing wheels, it should be borne in mind that too large products are inconvenient. If small wheels are installed, the cultivator will bury itself on soft ground. Therefore, they must be medium in size.
  • After this, the structure shaft is created. With a sledgehammer, it is necessary to break the nozzle from the grinder and place the workpiece, which is created from scrap, into the sleeve.
  • Then you need to weld the lug screw.
  • On one of the previously created handles, you need to attach the engine switch. To use the unit more conveniently, it is worth placing the controls based on the size of the hand.

It is worth remembering that when moving quickly, the cultivator is able to break the ground into clods. If the created device works slowly, this will lead to the fact that the soil becomes soft and the processing will be done more accurately. Such electric homemade products allow you to process small areas.

How to make a chainsaw tiller

Most often, motor cultivators are created from a chainsaw, since many site owners have similar devices. The manufacturing process begins with the manufacture of the unit frame. The structure to be created must have the shape of a cube. The engine is mounted on the upper corners, and the unit’s fuel tank is mounted below on pre-made mounts. The vertical posts of the foreground frame are intended for the location of the intermediate shaft supports.

The result is a self-made saw tiller, the center of gravity of which is located above the wheels. Thanks to the simple design device, you can repair the cultivator with your own hands.
