How to install the generator on a single-axle tractor Neva

It can be quite difficult for a beginning farmer to choose the right generator for a power tiller. But all is not as difficult as it may seem at first sight. The only and the most important factor to pay your attention to is the power of the device. Whichever generator for the agricultural machine you choose, its power must necessarily exceed the total capacity of the loads under which the single-axle tractor works. This will allow the device to work properly at 220 volts without the risk of surges in the electrical network, and feed all the electric appliances on the power tiller.

Often inexperienced owners of power tillers buy and equip their machines with generators to be installed on automobiles. This is best if you regularly use a powerful single-axle heavy-duty tractor on the farm. In other cases it is inexpedient to buy such generators because of their high cost.

How to choose a generator for a power tiller?

On today’s market you can find a wide range of generators designed to be exclusively mounted on motorcycles. The wide range of products sometimes plays a cruel joke on novice farmers and causes the inexperienced owner of an agricultural machine to buy an unsuitable factory alternator for his or her power tiller.

To avoid mistakes, there is one very important rule to follow: the alternator you choose for your power tiller should have the following rating. than the sum of all the loads that act on a single-axle tractor during operation. When choosing an alternator, this factor will allow the machine to operate stably at 12 volts without the risk of a short circuit or sudden voltage drop.

What is it?

Before you buy, let alone install and connect a generator for a power tiller, it is very important to know what it is.

The alternator has several components.

  • Stator. Is the “heart” of the electric generator and is a winding with steel sheets. Looks like a tightly packed bag.
  • The rotor. Two metal hubs, with a steel shaft-shaped field winding located between them. Simply put, the rotor is a steel shaft with a pair of bushings. The winding wires can be soldered to the slip-ring.
  • Pulley. It is a belt that helps to transfer the generated mechanical energy from the motor to the shaft of the electric generator.
  • Brush block. Plastic part that helps connect the rotor circuit to other circuits.
  • The housing. This is the protective box. Most often made of metal. Looks like a metal block. It may have one or two (front and back) covers.
  • Another significant element is the voltage regulator nozzle. It stabilizes the current voltage if the load on the generator becomes too much.

It is worth noting that generators for power tillers are not much different from generators for other vehicles or large devices, the only difference is the power.

Selection Features

When choosing an electric generator, the main thing, as mentioned above, is its power. It is easy to calculate your power requirements yourself. To do this, it will be enough to sum up the power of all the devices of the power tiller and buy a generator that has a higher value than this number. Just in this case you can be sure that the single-axle tractor will be able to provide power to all appliances without surges and interruptions. The standard value of current voltage for generators and are the same 220 volts.

The purchase of an automobile generator is worth thinking about only if there is regular, almost daily use of a power tiller.

In some cases, it is recommended to buy such an electric generator on models of heavy-duty tractors. But it is best not to buy such models because of the exorbitant cost of some copies in order to avoid the same expensive subsequent repair of the product.

How to make a generator on a single axle tractor?

Making an alternator for a power tiller used in the farm is much easier than it might seem at first glance. It will require a fully serviceable electric motor. it should be mounted on a single-axle tractor. The sequence of operations in the manufacture of the generator is as follows:

  • First of all, the electric motor to be used should be fixed in place. For this purpose it is necessary to make a frame, which should be screwed to the frame of the power tiller with the screws. Next, the motor is installed on the frame, the shaft of the latter must be in strictly parallel position with respect to the shaft of the regular motor of the motoblock;
  • After that you need to mount 2 pulleys. The first one is mounted on the shaft of the regular motor of the power tiller, and the second one. directly on the shaft of the used electric motor. It is very important to correctly determine the diameter of the pulleys used. if the size is chosen correctly, then the electric motor will rotate faster, allowing it to generate more electricity. In order to rule out the possibility of malfunctions, the diameter of each pulley used must be the same as the one marked on the nameplate. Pulleys whose diameters are 10-15% larger than the size indicated on their packaging will also be suitable;
  • Once the home-built generator has been made, it should be hooked up. The same wiring diagram described above is used for this.

When using a homemade generator, you will need to ensure that neither it, nor the electric motor used to operate it, overheated. The ingress of moisture inside the electrical devices should also be completely excluded. Another important rule is the voltage of the capacitors in the motor. This parameter should always be a little more than 400 Watts. if the power of the elements is lower, it is advisable to replace them with suitable parts.

The generator, made in such a way, can be used to work on the Neva motor blocks and agricultural machines of other popular domestic and foreign manufacturers.

To put a car generator on a single axle tractor, it will not take much time and effort, but it should be treated responsibly.

Because it will determine the performance of the machine as a whole. The alternator is connected to the machine by a special schematic diagram that shows all the connections. The winding can catch fire if connected incorrectly. Installing the generator on a single axle tractor with their own hands is carried out thanks to the two wires. In total, there are 4 wires in the block, including 2 blue. It is through two blue wires that the converter is connected. Then the red wire that feeds the headlights and charges. The creation will be helped by the following drawing.

How to make an alternator on a single axle tractor. simple about complicated

Make an alternator for a power tiller with your own hands is simple enough, if you follow the correct order of operations. The work will require an electric motor, which must be installed on the agricultural machine. The generator manufacturing algorithm is as follows:

  • To begin with, you need to install the electric motor on the frame of the motoblock. It is best to use for this purpose a pre-made frame, screwed to the frame of the unit by means of screws. Place and fix the electric motor in the frame so that its shaft and the shaft of the regular motor of the power tiller are strictly parallel to each other;
  • Next, you will need to install 2 pulleys. install one of them on the shaft of the gasoline motor of the motoblock, and the other on the shaft of the electric motor used. A large role for the proper operation of the entire system is played by the correct selection of the diameter of the pulleys used. it is these dimensions that determine the frequency of rotation of the electric motor. In order for the generator to work smoothly, the diameter of the pulleys should be the same as the nominal diameter indicated on the packaging of these parts. It is even better if the actual pulley diameter is 10% larger than the nominal diameter;
  • Having completed the mechanical assembly of the alternator you can now connect it to the power tiller. Use the diagram in the wiring diagram above to do this.

Self-made generator from an electric motor does not require special care. However, in order to extend the service life of the unit, a number of rules should be followed.

When operating your power tiller, pay attention to such nuances:

  • if you find that the electric motor installed on a single axle tractor has become very warm, then replace the regular capacitors of the motor with elements of lower capacity;
  • the voltage of the capacitors installed in the electric motor is of great importance. the capacitors with a voltage of at least 400 volts are considered to be the optimal choice. If the standard capacitors of the electric motor have a lower capacity, replace them with suitable elements;
  • try to operate the single axle tractor with the generator installed in the dry weather, since the moisture that can get into the electric motor, will inevitably lead to a short circuit inside the electrical system.

Adhering to these rules, you will prevent a failure of the homemade generator and significantly prolong its operating life.

The above methods are suitable for making and installing generators on the Neva brand motor blocks, as well as agricultural machines of other domestic and imported companies-manufacturers of equipment.

Possible problems and solutions

A serious breakdown, of course, without going to the service center or to professional repairers is not solved. But with the current uncomplicated ones are quite manageable for everyone on their own. Among the most common complaints from users we should mention the following:

Otherwise, it is clear that the installation of a motor-block generator is by no means complicated. over, in this case there is a chance to save significantly on it, as well as to be fully confident that it is really made qualitatively, with strict adherence to all norms and recommendations. Of course, this process will not be easy for beginners without experience working with electricity, but what is good, the acquired skill will be useful in the future.

Power tillers with PTO and differential allow you to perform a huge list of agricultural tasks. But even experienced farmers sometimes find it difficult to choose correctly one of these machines. Below we present our review of power tillers with PTO:

  • The Chinese power tillers of the Salyut 100-6,5 modification are on the 5-th place. Among the advantages of power tillers in this configuration are availability of the soft start system, excellent traction and modest fuel consumption. With small size and average power, these models are not bad for plowing virgin. The high-quality PTO of these power tillers allows using any of the known attachments;
  • The 4th place is taken by the professional motor blocks Huter GMC-9,0. These powerful machines are able to plow the soil of any density without interruption for rest. Last but not least, this was achieved due to the universal PTO, which allows you to use attachments of any size;
  • Russian motor blocks AGAT HMD-6,5 are in the third place. Technics of this brand is completed with a solid universal PTO, which allows the use of large-sized attachments with power tillers of this modification;
  • The 2nd place is taken by the average power tillers Neva MB-2B-6,5 Pro. High maneuverability, versatility and excellent controllability are the advantages of the technique of this brand. The only drawback of the models is the ill-considered mechanism of gas adjustment;
  • First place goes to the units Kentavr MB1012E, which are equipped with a quality reliable PTO, can easily withstand even the strongest loads. The basis of the design of motor blocks Kentavr MB1012E is a reliable diesel engine with a capacity of 12 liters. с.

All the listed by us motor blocks are characterized by high reliability, long service life and ability to perform almost all the tasks assigned to them. The presence of the PTO allows the use of these models in combination with dippers, plows, potato tillers, trailers, harrows and other devices.

Classification of PTO shafts for power tillers

PTO serves as a mechanism that transmits engine-generated torque to the working elements of attached implements used. All PTOs can be classified according to their operating principle.

Taking into account this factor, we distinguish such mechanisms:

  • Dependent PTO. a feature of these PTO shafts initially lies in their simultaneous rotation with the clutch provided for the power tiller. If the clutch is disengaged, the PTO used also stops;
  • Independent PTO. the drive of motor blocks with such mechanisms lends itself to a more even load, which allows the owner of the unit to use various auxiliary mechanisms of the motor block even when the motor is turned off;
  • Synchronous PTO. stable operation of such PTO shafts is ensured only at uninterrupted rotation speed of the machine wheels;
  • asynchronous PTO. the principle of operation of these mechanisms is completely opposite to that of the previous type. These PTO shafts are commonly used for the installation and application of sprayers, seeders and other attachments on a power tiller that operate at low speeds and with frequent stops.

This classification allows each farmer to choose the right universal joint shaft machine for him. If necessary, you can also buy a PTO of another type for subsequent installation on an existing single-axle tractor.

In the modern domestic market you can easily find a variety of models of power tillers, which are factory equipped with a PTO. All of them are actively used in combination with numerous attachments, thus enabling them to perform a wide range of agricultural tasks. We offer our review of power tillers with a PTO for use in both small and quite large farms. The units we selected include:

  • Ugra NMB-1H15. powerful power tillers in this configuration are in high demand due to their cross-country capability, stable operation in all conditions and durability. Thanks to the PTO these machines can help in effective plowing of virgin lands, harrowing, ridging, planting, harvesting and transportation of crops, the total weight of 500 kg;
  • Motor Sich MB-8. these professional units are considered universal agricultural machines. They are equipped with a motor, power of 8 hp. с., Wide wheels and a robust steel body;
  • Caiman QUATRO MAX 70S TWK. medium-weight power tillers allow in all weather conditions to use a huge plow, harrow, seeder, potato tiller, trailer and other attachments to work on the site;
  • Salyut 100 L6,5. these Russian power tillers are known for their exceptional reliability, highest quality of assembly and stability. The power tillers of this model are compact enough and do not consume much fuel;
  • Zirka GN 151 E. Chinese heavy duty motor blocks are characterized by high power and maximum possible service life. Reliable PTO in their design allows using each such diesel unit to work with plow, dipter, harrow, snowplow, seeder and other common equipment among farmers.
