What you can make from a power tiller engine
Minitractor. is a tractor based on the design of a motor-block. Mini-tractors are divided into three categories: homemade, converted using prefabricated kits and factory-made.
So, how to make a homemade mini-tractor from a power tiller, the first thing you need to think about is the change itself, as well as the possibility of installing attachments: plowing rotary machines, mowers, shovels-welders.
Let’s briefly consider the structure of the mini-tractor from a power tiller, which is made by the hands of the folk craftsman.
The single-axle tractor is located on a prefabricated homemade frame. The installed drum brake mechanism is taken from the Zhiguli. From there they take over the steering wheel, which eliminates the problem of finding replacement parts. Ready-made mini-tractor pleased with the ease of operation and thoughtfulness in detail. To reduce discomfort while turning, the handle is installed next to the steering wheel, which unlocks the differential.

Single axle tractor with their own hands Living in the countryside or having your dacha plot, you will sooner or later have the desire to facilitate and make more automated their work. Fortunately, the market of earthworks equipment offers many variants of various equipment for plowing, planting and harvesting. But unfortunately, this technique can be too expensive. The most popular tool in working with the soil is. a single-axle tractor! Motoblocs come in. electric diesel and gasoline. Now we will tell you how you can make a single axle tractor with your own hands and save your money. The main advantage of a homemade power tiller is the minimum cost for the assembly of parts.All materials for the construction of the tractor you can find in the barn, or buy at the market without spending a penny. To create a tool, you can use an electric, gasoline or diesel engine. You can use the engine from a moped, chainsaw and scooter. The quality of self-made machine can be on par with that of professional models. For maximum ease and quality work, you must have the right tool:
To assemble your own power tiller, you do not need to spend a lot of money. All you need is simple inexpensive parts, free time, the ability to use tools properly and a good mood.There are several options, from which it is possible to make a single-axle tractor. Single-axle tractor from ZAZ Before you start, you need to build drawings for the construction of a motorblock on the basis of the gearbox from ZAZ. This single axle tractor has a chassis with one axle, and is not very big in size.It will be great for such works as
During the construction you may have questions, so before you start assembling the tool, make sure that all design features are well studied.To construct a motorblock on the basis of the gearbox ZAZ you must have these parts:
Most often, when constructing a motorblock from a gearbox ZAZ need to use a lightweight axle. How to assemble the unit ? For the axle you will need a tube of up to 10 centimeters in diameter. At the ends of the tube, weld the ball bearing housings, on which the wheels will be attached.The gearbox from ZAZ needs to be attached to the pipe with brackets that need to be welded. Mount the engine on the gearbox. Attach the handles for working with your motorblock to a perpendicular retainer. This single-axle tractor is ideal for long-term use and a lot of work. A single-axle tractor made from a chainsaw For productive work in the garden and vegetable plots, a single-axle tractor made from a chainsaw is more suitable.If you have a saw that you haven’t used in a long time, that’s a good reason to use it to convert to more useful equipment.For the construction, you will need simple tools.And the process of assembling the new garden helper, you need to start with the construction of the frame. Next, you need to attach the engine to the crossbars of the base of the tiller. Fuel tank, be sure to install under the engine, for this you need to use brackets. Weld the bearings on the supports. The ignition lock fits from any car. Important advantages of a power block from a chainsaw
These options for constructing a power tiller are simple enough to assemble on your own. Important! If you have nevertheless decided to build such a tool yourself, then it is worth with great attention to the accuracy of drawings, the quality of parts and your ability to use the welding machine. Be careful while working, don’t neglect safety precautions when working with tools!
How to properly run-in the single axle tractor?
The running-in of the machine is simply necessary. In the process, all gear pairs are lapped for further normal operation.
All work must be performed in strict compliance with the operating manual. The manual contains information on the permissible loads of each machine model.
It is important to follow a number of rules, including:
The single-axle tractor should be run-in in accordance with the specified time;
If the depth of plowing is specified up to 50 centimeters, then the processing takes place at a depth of 30 centimeters;
A new single-axle tractor can be used with or without oil. This is an important detail. It is important to pay attention to the selected brand of machine oil;
Determine the make of engine. The machine is marked with a decal.
After filling the crankcase with oil you can start the running-in. If there are any problems, the oil drain plug is unscrewed to check for grease.
The procedure must be carried out slowly and carefully, do not accelerate so as not to provoke negative consequences.
Running-in of diesel and gasoline engines
Running-in of the engine is performed not only after the purchase of new equipment, but also when installing a new motor, after major repairs, modernization or replacement of individual assemblies of the motoblock (motocultivator).
Before starting the procedure, check the correctness and quality of the assembly of equipment, the fastening of all connecting bolts, the presence of the necessary lubricants. Further algorithm of actions is as follows:
- Pour the required amount of oil into the crankcase and check the oil level with a dipstick.
- Add the required amount of fuel (A92 gasoline or diesel fuel, depending on the type of engine) to the fuel tank.
- Check oil level sensor and relay connection.
- Open the fuel tank cock.
- Turn the engine hand starter several times without turning on the ignition. On the diesel engine it is obligatory to switch on the decompressor.
- Open the choke on the gasoline carburetor.
- Start the engine and close the choke as it warms up.
After that you can start the running-in period. At the first stage it is recommended to start with low rpm, gradually and smoothly increasing to values just above average. It is necessary to work on all the gears of the motoblock alternately, for 1-2 hours. This allows you to test not only the engine but also the gearbox of the machine.
The second phase involves work on cultivating, plowing and transporting small loads (up to 200 kg). It is very important at this stage not to exceed the permissible load of the single axle tractor specified in the instruction manual. Example: if the maximum tillage depth indicated in the data sheet is 30 cm, the depth of the tiller should not be more than 15 cm when running-in the engine.
Running-in of a diesel engine is not fundamentally different from that of a gasoline engine, but it is important to remember that any engine does not like prolonged work at idle with the use of high revolutions. This is a very common mistake and can have serious consequences, up to and including engine overhaul. For different power harvesters the running-in process may take up to 10 hours.
After the engine and power tiller run-in period is complete, the oil in the crankcase and transmission should be changed to a new one, based on the recommendations in the instruction manual.
Repair of Moto-Block with your own hands. Tips and practical advice from the experts
Like any other technique, a single-axle tractor needs timely repair and maintenance. Naturally it is better to leave this job to professionals who have experience and all the necessary equipment at hand. But you can do most engine repairs yourself. And the more so that you can provide first aid to the engine to finish agricultural work, and only after the overhaul of the device.
The first thing that should be paid attention to. the service life of diesel engines is different from the service life of gasoline engines. The diesel engine can provide as much as 4000 motor-hours. Gasoline engines can deliver 1500 motor-hours. It is for this reason the price of diesel motor blocks is much higher than that of gasoline models.
All the damages that can occur during the operation of a power tiller can be divided into two groups.
The first is engine failure (often start-up problems or frequent malfunctions).
To the second category of faults of power tillers can include breakdowns of other mechanisms and assemblies
Failure of various engine systems (chain lubrication, cooling, etc.).)).
Proper diagnosis. the key to successful repair of motorblock. If we talk about the maintenance, its regular maintenance helps to detect minor problems that over time can develop into serious damage.
If you don’t have enough experience, knowledge, tools or materials to repair or maintain your engine, don’t try to do it yourself.
If you can’t start the single axle tractor and all your attempts are unsuccessful. it means that there are some faults in the starting system or in the engine. First of all, you need to look at the plugs. If they are dry, then the fuel is not reaching the cylinder of the motor. There are several reasons for such failures, from which the repair of motor-block:
1) the fuel tank is out of fuel,
3) The hole in the gasoline tank plug is clogged,
4) foreign objects got into the fuel system.
In order to solve the fuel supply problem, you need to proceed as follows:
We fill the tank motoblock, and then open the fuel tap and clean the drainage hole (it is located in the cap of the gasoline tank).
Then we remove the fuel tap and drain the gasoline from the tank. Flush the fuel tank thoroughly with clean petrol.
The connecting hose, which is located near the carburetor, you need to remove and blow it with a fuel pump along with the carburetor jets, without disassembling it.
If the fuel reaches the carburetor, but does not enter the cylinder. then the problem is in the carburetor. In order to fix it, it must be removed, disassembled and thoroughly clean. After the assembly is assembled and installed in its place.
Before proceeding with these works, it is worthwhile to refresh your knowledge on the principle of carburetor operation.
Engine systems malfunction at startup
If, after checking the plugs, you find that they are still wet, then there is no problem with the fuel supply. But the engine still will not start. You need to repair your power tiller and it is possible that the ignition system malfunction is the reason.
On the electrodes of spark plugs there is soot (in this case you should thoroughly clean the plugs with sandpaper, and then they need to be washed with gasoline and dried).
The gap between the electrodes does not correspond to the value specified by the manufacturer in the engine manual (then you need to adjust the gap by bending the side electrode to the required size).
Damage to the spark plug insulators or high-voltage wiring (they cannot be repaired, the spark plugs or wiring must be replaced).
The “STOP” button is shorted to the common ground (in order to start the engine under normal conditions, this short circuit must be eliminated).
Broken contacts in the spark plug corners (troubleshooting is necessary).
The gap between the starter motor and the magnetic shoe does not correspond to normal values (the gap must be adjusted).
Defects in the stator of ignition system (in this case the stator must be replaced).
Air suction through the carburetor seals, spark plugs, spark plug heads and cylinders, as well as carburetor and engine cylinder connections
If you find leaking connections, check the mounting bolts, tighten them and the spark plugs, and check that the gaskets between the spark plug heads and cylinders are intact.
Carburetor choke not closing completely
In order to solve this problem, you should ensure easy movement of the flap and check the correct functioning of the actuator. If there is jamming, this must be corrected.
Compression problems and carburetor malfunctions
It happens that the engine starts, but its start is accompanied by considerable difficulty and takes a lot of effort. The engine is functioning badly enough and is not able to develop optimum performance. The engine compression loss is one of the possible causes of this malfunction. It can be determined by the following signs:
There is soot visible on the valve surfaces and cylinder seats.
The intake valve is damaged or has lost its original shape.
In order to restore compression, the following measures are taken:
Check the condition of the engine timing mechanism.
Thoroughly clean the fouled parts or replace them completely if defects are detected.
Assess the condition of the piston rings and replace broken elements.
If thick black smoke comes out of the muffler when the engine is running and the spark plug electrodes are covered with soot or there is too much oil on them. it can be a signal of such deviations:
Carburetor gets too rich a fuel mixture.
The fuel valve is leaking.
The piston ring is worn out.
It is necessary to clean the air filter due to its clogging.
To fix these malfunctions it is worth doing these actions:
Clean or replace the air filter.
If the smoke that comes out of the muffler when the engine is running is light in color and a white deposit is visible on the electrodes of the spark plugs. is a signal of a poor concentration of fuel mixture in the carburetor. Such problems are solved by adjusting the work of the carburetor.
ATV with his own hands!
On the question of what you can make from a power tiller more, there is one answer that almost everyone will like. an ATV. Today this means of transportation is very quickly gaining popularity. In this case, it is not so difficult to make it from a power tiller. You will have to carry out the procedure for mounting the second axle. New wheels designed for cross-country riding can be installed later. You will not have to make the disks yourself. It is enough to just take suitable car disks.

It is worth noting that the homemade ATV will differ from the original one in two main qualities. a relatively low speed and a standard for a motorcycle landing. As for maneuverability, here it is not inferior to branded samples.
Homemade from power tillers
It is not difficult to assemble a single axle tractor out of spare parts by yourself. But if you want to get a qualitatively made machine, a device that will not require rework, then you need to have a certain knowledge, know how to use the locksmith’s equipment, and most importantly. have a detailed description of the structure of your future machine. It is best to get the drawings on the web.
If you want to build a homemade single axle tractor with their own hands, old motorcycles and chainsaws will be ideal. The motorcycle can be almost anything. In this case, the power of the chainsaw must be big enough. Motorcycles “Ural” or Zaz will be an excellent candidate. Surely you want to know what you can make from a power tiller. In this article we will tell a little about it.
Self-Made Kart with an engine from a power tiller
Sports car kart, with an engine from a motorblock, built by a craftsman: photo, as well as a description of the construction of the self-made.
Karting is quite an interesting sport and active pastime. To build a sports car, you can on your own. We propose to see a homemade kart, made by one of the craftsmen for his son.
Car frame is welded from round tubes, some elements of the frame, bent on a pipe bender.
The car is equipped with a gasoline engine (6.5 л.s) air cooled from a Chinese power tiller. There is also a centrifugal clutch. From the engine to the rear axle is a reduction chain gear. The rear axle has disc brakes from a scooter.
Wheels together with hubs, taken from Go kart.
Pedals “gas” and “brake” are installed at the front. Steering like a normal kart. Also on the rear axle, a pair of shock absorbers is installed.
The result is a simple and neat little sports car for my son. The power of a motorcycle engine is enough for a moderate speed kart designed for a child.
