Repair and installation of the starter on the tiller with his hands
The starter to the motor-block. it is, at first glance, a complex mechanism, but, in practice, in its structure there are no complex elements. These devices act as a starter component, with which the internal combustion engine is started. The work of the device is that it creates a pull to rotate the crankshaft and camshaft. Additionally at this point, a spark is fed to the glow plug, which allows you to form the necessary traction in the combustion chambers for the subsequent independent work of the engine. In practice, the following variants of starters for power tillers can be distinguished:
In each case, the principle of operation is similar, but the order of starting is significantly different. If in the first case, it is done manually, then in the second variant, everything is done electronically, and the hands turn only the key in the ignition mechanism, or the start is made from the button. Most older power tillers are equipped with a mechanical manual starter, which is why it is necessary to consider in detail how to repair the device, if necessary.
Important! Modern motor blocks are produced with an electric starter, but if it breaks down, you can also repair the device yourself
Manual version device
Before considering how to repair the manual starter for a motor-block, it is necessary to consider what elements this accessory consists of:
- The body, made in the form of a drum;
- inside there is a large and a small spring;
- In addition, there are tongues and a washer;
- The coil for starting and the starter cord;
- elements used to fasten.
All elements are made of durable materials for maximum resistance to wear and tear. The device is started by a coil, which is driven by a cord. In some cases, former models of power tillers were equipped with special footrests for starting, like motorcycles. Repair of the kickstarter (starter foot) on a power tiller practically does not differ from the work with the manual mechanism, except for the presence of a special remote handle and internal cam mechanism instead of the coil and cord.
It is worth noting that the electric mechanism is also equipped with a similar device, but here provides a more complex technology.
The structure of the electric starter
As previously mentioned, this part has a similar structure to the manual version, but differs in that it also includes the drive brushes, cam mechanism, wiring and electric drive. The last component simulates the mechanical forces that are generated by the incoming electric power and the built-in electric motor. all other elements are similar and have the same function, namely to start the engine by turning the camshaft and crankshaft.
Important! An additional difference between the elements is that when repairing equipment and disassembling the device, it is also required to disconnect the electrical supply wires
How to repair the starter motor with your own hands
Despite the high quality and reliability of modern starters, some owners are sometimes faced with the need to repair them. Most often the breakdowns of the mechanism are insignificant, which allows you to quickly fix the problem with your own hands. The order of disassembly and further repair of the mechanism is as follows:

- Repair of the unit should begin with a study of its scheme. If the design of the power tiller includes an electric starter, then before dismantling the mechanism it is necessary to become familiar with the location of its terminals;
- Use the wrench from the power tiller kit to remove all the screws and nuts that hold the mechanism in the structure of the power tiller;
- If you dismantle the unit for the first time, we advise you to take a picture of the starter before finally removing the mechanism from the machine;
- Next, unscrew the washer located in the center of the drum housing and carefully inspect the internal parts for breakage;
- All further actions depend on the faulty parts of the starter. If the cord is out of order. it is frayed or torn, then to replace it, you will need to wind a new product, adhering to the marks on the drum body of the mechanism;
- Another common breakdown is a faulty spring, or more precisely, its tendrils, the edges of which should be bent in the shape of hooks. If the tendrils are torn, then the edges of the spring must be heated, and bend them so that the spring can be caught in the holes in the drum. The remaining length of the spring is important. make sure that the part is not stretched too much. If you find that the spring is very short, or it has already begun to rust, it is better to replace it entirely.
Before you mount the starter back on the single-axle tractor, we advise you to pre-clean the space inside the construction of the unit. This will prevent debris from getting inside the motor, carburetor and spark plug.
How to repair the starter motor cultivator with your own hands
Let’s consider how to repair the starter motor with your own hands. Before you start repairing the manual starter, you need to find the manual for its operation, which contains a diagram of the device. Then you need to prepare a wrench to loosen the mechanism.
Before you begin dismantling the device, it is necessary to photograph it, so that you can then properly assemble all the parts and components.
After that unscrew the washer, which is located in the middle of the housing. Having opened the lid, it is necessary to carefully inspect all the parts that are located inside the drum and determine which of them are damaged. It is necessary to carry out a very careful and careful inspection of small parts, so as not to accidentally spoil or lose them.
In most cases, the repair of the kickstarter on a power tiller is to update the components that have failed. For example, you can change the starter cord if it is torn or frayed.
If the big spring is out of order, it should be removed from the reel. There are usually hooks on the places where the spring is attached. If the design does not have them, you need to heat the ends of the spring and bend them in the right direction. If the spring is completely out of order and there is pronounced metal fatigue, then it is not necessary to try to return this spring to functionality. In this case, it is best to replace it with another. After that, the device is installed in its place.
In addition to the manual starter, there are spring and electric starter on a single axle tractor. The spring mechanism has a simple design, it is easy to start. The device will start after sliding the handle of the power tiller. The motor is accelerated by means of a semi-automatic spring. You can replace the manual starter with a mechanical one by yourself.
The electric starter for the power tiller is connected to the battery which it draws its power from. The electric start of the device is carried out by means of a starter button. The battery determines how powerful the electric starter is and how long it lasts. The electric starter is installed according to the electric circuit of this design. A single-axle tractor with an electric starter is durable, reliable, and has a long service life.
Unfortunately not all manual tillers can be converted to spring or electric. Therefore, before starting work on replacing the manual mechanism, you need to study the manual and the capabilities of the power tiller and find out whether such a conversion is possible.
Farmers should be aware that at the beginning of the work all power tillers work properly. Gradually on the assembled unit various components fail. In order to prolong the service life of the power tiller and all its parts and components it is necessary to have a regular check-up of the machine and to take proper care of it. All units and components must be periodically lubricated with machine oil, checking their performance. To increase the productivity of the cultivator and extend its life, you need to properly care for this technique.

What is a MTZ starter?
Gasoline starters on MTZ are of the PD-10 type. When it is started, the reducers begin to transmit torque to the power unit, unwinding it gradually. The advantage of the gasoline device is unpretentiousness, the ability to use not very good quality fuel, which does not affect the performance at all.
An electric device is also installed on the MTZ-80, which is powered through a special mechanism connected to the battery. Usually such kind is necessary for tractors with powerful engines designed for long-term loads and constant work. Electric requires mandatory connection to the engine so that the clutch can transmit torque to the flywheel.
Thus, what is the best starter for MTZ to put, the tractor owner must choose for himself. Retrofitting depends on the type of work to be done and the technical characteristics of the machine itself. Climatic and weather conditions are also important. In the warm season or in regions with a lot of sun, a not very powerful motor is needed. Therefore, for winter it is recommended to use a regular gasoline type PD-10, and in summer give preference to replacing it with an electric.

How to choose a starter for a single axle tractor?
Moto-blocks are not a complex design, but they do contain certain features. For example, when using this device, two starters work simultaneously: a main starter and an auxiliary starter. In addition, the role of helpers can also be performed by spring and electric variants.
The latter are considered the most popular, because they can be installed on motor blocks without problems and carry out repair work. The distinctive feature of such starters is also that they are unpretentious, so they do not require too careful use.
Working principle and purpose
The main purpose of a power tiller is to plow the field or to dig it. Secondary tasks assigned to it can be snow plowing and cargo transportation (with a trailer attached). A single-axle tractor is a device built on the basis of a single-axle frame and developed on the basis of a small tractor device. The user steers the power tiller and walks behind it.
According to the type of work the devices are differentiated into wheeled (tracked) and power tillers. In the wheeled device, traction is created by the undercarriage, and in the motocultivator. the tool of labor is installed on the axle at once. Different models of power tillers use a different set of mechanisms, but, as a rule, a milling power tiller is used for domestic appliances, and a plow mounted on wheels is used for professional. The tool used is a tiller or a tiller.
The idea for a small device that performs the work of a full tractor when cultivating arable land originated in the early 20th century in Europe because of the inconvenient passability of full tractors on private fields. Thus, in 1912, the German company Siemens-Schuckertwerke launched mass production of motor cultivators under the name Siemens Bodenfrase.
How to put the starter on a single axle tractor. the algorithm in detail
Even novice farmers have no problems with dismantling, disassembling and mounting the manual starter on a motor block. However, the assembly and installation of the electric starter inexperienced owners of power tillers raises a number of questions. As a result of improperly performed procedures, the engine starting mechanism refuses to work, causing the starter has to be carried to a workshop. To avoid this need, let’s study how to install the starter on a single-axle tractor at home. Installation is as follows:
- To install and secure the crown on the flywheel of the motorized tractor, the flywheel will need to be removed. To do this, remove the air filter of the unit to get free access to the internal structure of the motoblock;
- After that, remove the protective cover, remove the screws that hold the hand starter basket, the flywheel nut and the flywheel itself. Dismantling the flywheel of the motor-block starter can cause certain difficulties, so to remove this part it is better to buy a special detachable wrench in advance. After removing the flywheel, do not forget to unscrew the key located immediately behind it;
- Next, you need to install the alternator. At the same time, its wires slip into the hole in the steel wall of the engine, and install the generator in the seats on the wall of the engine;
- Then place the alternator magnets inside the flywheel so that the holes in both elements align. Screw the two parts together and mount the crown. Before doing this, the crown must be heated using a can burner;
- Install the assembled assembly back on the engine, screwing in the flywheel key and nut at the same time;
- Screw in the hand starter basket, secure the shroud, and install the motoblock air filter in place;
- Next remove the starter mounting plug and install the starter itself on the single axle tractor;
- After that, connect the alternator wires to the charging relay;
- Connect the starter terminals to the unit’s battery and start the single axle tractor.
As you can see, to install the starter to the power tiller is not so difficult as it may seem at first glance. The main thing when assembling with your own hands. strictly follow all the rules and recommendations listed in the algorithm.
All the described methods of repair and installation of the starter are suitable for mounting the mechanism on motor blocks Neva, Kaskad, Agro and agricultural machines of other well-known manufacturers.
