Many manufacturers produce this agricultural mechanism without built-in lighting. This is where the question arises, how to connect the headlight to the walk-behind tractor yourself.

Electrical diagram of a walk-behind tractor

Before installing lighting on a walk-behind tractor, it is worth considering its class. These units of the medium and heavy class are equipped with a generator, which serves as a source of charge for the battery and power supply for the headlight. With these variants of the mechanism, it is possible to connect several headlights (front and rear for a trailer to the walk-behind tractor), as well as direction indicators.

The start of the walk-behind tractor is provoked by an electric starter and a battery, which is installed in a special tray and firmly fixed to the frame of the mechanism. The battery is powered by a generator. The generator power is sufficient to put into operation all the necessary electrical devices of the mechanism and connect the headlights to the walk-behind tractor. The manufacturers themselves have foreseen the desire of users to figure out how to make light on a walk-behind tractor, using generators on constantly rotating magnets with automatic regulator voltage with a power reserve of about 30%. To connect all sources electrical supply to the generator, it is worth assembling them into a single circuit with double insulation wires. The diagram described above is an ideal picture, but sometimes you need to modify something or figure out how to connect the headlight.

How to connect a headlight to a walk-behind tractor with your own hands

Many walk-behind tractors are sold without factory-connected headlights. But you shouldn’t be upset about this, because even an inexperienced master will be able to understand how to make a headlight for this agricultural unit.

Sometimes many manufacturers offer customers ready-made headlights for a walk-behind tractor with the addition of a switch and wire. But the opportunity to purchase this kind of product will negatively affect your material condition. Factory lighting systems for walk-behind tractors are much more expensive and only manufacturers benefit from this, wanting to make money on gullible consumers. Why spend extra money if you can simply figure out on your own how to install lighting on mini-tractors using improvised, sometimes unnecessary, devices.

You can use different types of lighting elements:

• Additional headlights from a moped, scooter, tractor, car or other vehicle at your disposal.
• You can buy a used headlight on the automobile market in places where transport and electrical parts are dismantled and sorted.
• You can select a new headlight taking into account the color of the mini-tractor itself.

The ideal option is to choose a headlight for a scooter or small motorcycle. In addition, it is worth purchasing the required length electrical wire and a toggle switch to switch the lighting.

It is most convenient to connect the toggle switch to the steering column near the gear shift lever. The headlight itself may be located in the steering column or on the front of the engine. But the first option will be preferable. On an engine, the headlight will constantly become dirty while the mechanism is moving, especially sometimes in the rain.

The next step in connecting the headlight is to run wires to it. The mechanism may include a connection point for the factory headlight. IN in this case just connect the wire to it. If there is none, then the power should be removed from the oil pressure warning lamp terminal. We connect the wire to the switch, and then to the headlight. The cord should be attached to the steering column using electrical tape or clamps.

Also, many are concerned about the question of whether it is possible to make light on a walk-behind tractor without a generator. It is worth noting that in mandatory A battery is required, which will be installed using a quick-release mount and recharged in the workshop.

For a walk-behind tractor, there are wide limits to its use, ranging from plowing land, pumping water to cultivating virgin soil and transporting heavy loads.

Connecting an electric generator to a walk-behind tractor.

A powerful walk-behind tractor or cultivator can be equipped with electric generator, which will charge electric battery or power an electric lighting lamp to work in dark time days. The battery, in turn, is intended, first of all, to start the engine of the unit from an electric starter installed by the manufacturer or independently. For additional lighting, you can install one or more lamps with headlights or connect additional safety light indicators used when moving a walk-behind tractor with a towbar on public roads.

Giving away electric power a working electric generator must be sufficient for the installed electrical load, and to be more precise, when all installed electrical equipment is used simultaneously on the walk-behind tractor, the electric generator must ensure its operation without a drop in the output voltage and without changing the current consumed by electrical devices. The power reserve on the generator is desirable within 20% -30%.

The battery capacity must correspond to the starting current of the electric starter and the current at maximum load all electrical equipment. Well, what electrical equipment can be used on a walk-behind tractor? — Headlight, horn and electric starter. On the tow hitch there are direction indicators, brake lights, and side lights. Additional electrical equipment is installed on the tow hitch, from where its control and connector for connecting it are output, or directly on the unit itself, if it is used for conversion into a mini tractor.

Most designs of electric generators on walk-behind tractors are made without electrical excitation, but with excitation by rotating permanent magnets. Mostly single-phase generators are used alternating current, connected by two conductors to the on-board network through a separate electronic unit, which simultaneously functions as a rectifier, voltage stabilizer and current regulator while charging the battery.

Many who purchase walk-behind tractors that have been disassembled believe that the generator has two wires, one of which is ground and the other +. Somehow the generator is equipped with wires available from the assembler with different color coded and with terminals suitable for the connection: black - on the body, terminal for a bolt; red on +, under the connector.

With this connection, the electrical equipment of the walk-behind tractor b will have to eat alternating voltage, which will be noticeable on the connected electric lamp. Low revolutions - the lamp glows weakly, and at high engine speeds the glow on the lamp intensifies. With this connection, the battery is not charged, but, on the contrary, receives destructive impulses and is discharged into the generator winding. In the worst case, the generator winding overheats and burns out.

An example of this Chinese electric generator YFF1690 , the winding of which burned out due to incorrect connection to the electrical circuit two minutes after starting the unit’s engine. Details.

Electric walk-behind generator The YFF1690 is connected with two wires to the electronic unit, most of which are equipped with four wires, the two blue ones are designed to connect to the electric generator wires. The black wire from the electronic unit is connected to ground power unit, equipped with a battery and an electric generator.

The red wire is the stabilized voltage output, which powers the electrical equipment of the unit, and through which the battery connected through an ammeter is charged. Naturally, the electrical circuit contains an ignition switch, a light switch and even a horn button. And the most important and noticeable switch is the mass switch.

How does an electrical circuit work with a generator? YFF1690 .

The electrical voltage generated by the YFF1690 generator is supplied to a rectifier located in the electronic unit. Inside the electronic unit there is an electronic voltage stabilizer and electronic regulator current. The voltage stabilizer keeps the output voltage at the same level, regardless of the voltage generated by the generator, which varies depending on the speed of its rotor.

The current regulator regulates the charging current of the battery, which operates in buffer mode.

When the electric starter is turned on, that is, when the engine of the unit is started by the starter, the battery consumes a certain amount of current. The running engine transmits torque through a belt drive to the generator rotor, which will begin to generate electrical voltage supplied to the electronic unit. But since after starting the engine with an electric starter, the electrical capacity of the battery has decreased, all electrical consumers will be powered by the voltage removed from the electronic unit until the battery is charged to a level determined by the electrical capacity.

When the battery is fully charged, no voltage will be supplied from the electronic unit and all electrical appliances will be powered by the battery until the voltage at its terminals drops by 1/5 - 1/4 volts, after which the voltage supply from the electronic unit will resume and the battery will be recharged.

Switching on and off by the electronic unit occurs in a very short period of time, and monitoring of the charging process and consumption is carried out through an ammeter installed on the instrument panel.

Thus, the electronic unit is an electronic regulator-switch-stabilizer. Switch - regulates the charging current and switches consumption sources: battery - generator. Stabilizer - stabilizes the output voltage.

IN Lately very often the manufacturer of motor units completes the electrical equipment electronic units without a current regulator, which has a bad effect on the condition of the battery, which is constantly under voltage. Ammeter indicates D.C. charge within 3 - 6 amperes.

The battery overheats, the electrolyte boils away, the plates crumble, but this is in the worst case. The mains switch saves, which can be used after half an hour of operation, when additional lighting or other installed electrical appliances are not used.

How to make light on a walk-behind tractor, since most models are not equipped with headlights? A walk-behind tractor (mini-tractor) is a mechanism that is designed for agricultural work (ploughing, cultivation, watering, etc.). Many models can be used as a vehicle using mounted trailers. In this form, walk-behind tractors transport people and cargo, which makes harvesting easier.

Electrical system of the unit

Medium and heavy walk-behind tractors are equipped with an electric generator that charges the battery and powers the headlight. The main function of the battery is to start the mini-tractor engine using an electric starter. On medium and heavy walk-behind tractors It is possible to connect several headlights (main and rear for a trailer), direction indicators.

The power of the operating generator is sufficient for the installation of additional electrical equipment, as well as stable simultaneous operation of all electrical devices of the walk-behind tractor. Manufacturing plants have provided the possibility additional installation electrical equipment and equip mini-tractors with generators with a power reserve of about 30%.

The battery capacity corresponds to the starting current of the electric starter. Most models of mini-tractors are equipped with generators without electrical excitation. It will be replaced by constantly spinning magnets. Most often, manufacturers install single-phase generators that produce alternating current.

Self-installation of headlights

If the unit was purchased without a lighting system, then do not be upset. You can install it yourself. Some manufacturers separately sell a lighting kit (headlight, wires and switch), earning extra money from this option, understanding that most owners will use the walk-behind tractor as a vehicle. There is a special place on the engine for connecting the factory headlight. The cost of such a kit, depending on the manufacturer, ranges from 1800 to 5000 rubles. It would seem that this is not a lot of money compared to the price of a mini-tractor, but why spend it if lighting can be made from improvised means?

Let's take a closer look at how to connect a headlight to a walk-behind tractor. The first step is to find the lighting element itself. Almost every unit owner has another mechanical means(car, moped, scooter, tractor), which comes with additional headlights. If this is not the case, then a used headlight can be purchased at dismantling sites or in the automotive market to save money. If possible, it is best to purchase a new headlight, which can be matched to the color of the mini-tractor. A headlight for a small motorcycle or scooter is suitable for this.

It is necessary to purchase both a toggle switch and the required length of electrical wire.

The most convenient place The headlight toggle switch is installed in the steering column near the gear shift lever.

Install and secure the switch. Next we move on to installing the headlights. Find a place that is convenient for her. The best place to install this equipment is the front of the engine or the steering column. Experts advise mounting the headlight on the steering column pipe, because one placed on the engine will become dirty when driving in the rain. Next we stretch the wires. If there is a place on the walk-behind tractor to connect the factory headlight, then we connect the wires to it, but if it is missing, then it is most convenient to extend the power from the terminal of the oil pressure warning lamp. Next, we connect the wires to the switch, and from it we pull the cord to the headlight, using the body of the walk-behind tractor as a ground. We fasten the wires to the steering column using clamps or electrical tape.

The question of how to make light on a walk-behind tractor must be decided by everyone who purchased this unit without a standard headlight. Today, most models of domestic and foreign production are designed to work only during daylight hours. And those that have a built-in flashlight do not always provide high-quality lighting. The factory headlight illuminates a narrow sector in front of the car and quickly becomes dirty. Available for sale ready-made kits, which can be installed on the Neva, Plowman, Volgar, Forza and other units domestic production. With average quality, such sets have high cost. You can save a lot of money if you make the light for the walk-behind tractor with your own hands. With a headlight, the motor cultivator will become much more functional and easier to use. Let's consider options for how to connect a headlight to a walk-behind tractor.

Using a generator

If the unit is equipped with its own generator, then resolving the issue of lighting arrangement is greatly simplified. You just need to install the flashlight and supply power to it.

To do this you will need the following tools and devices:

• electric drill;
• soldering iron;
• Screwdriver Set;
• spanners;
• wire cutters;
• stationery knife;
• electrical cable;
• heat-shrink tubing;
• headlight, side and turning lights.

Installing a headlight on a walk-behind tractor using a standard generator is carried out in the following sequence:

1. The bases are screwed to the unit body lighting fixtures. It is advisable to place the headlight on the walk-behind tractor on a separate bracket located on the front part with an elevation above the ground of 100-120 cm.
2. We install buttons for turning on the flashlight, turning and side lights on the steering column. You should choose devices of increased strength and moisture-proof design. Fixation is carried out with clamps or metal screws.
3. The electrical cable is pulled into a corrugated tube. This must be done to ensure that the wiring is protected from moisture. mechanical damage and rodents. The corrugated tube is pulled to the steering column and frame so that there is no sagging.
4. The wires are connected to the generator and electrical equipment terminals. The engine is started and the functionality of the lighting system is checked. After this, all twists and joints are isolated.

When working on Idling and at low speeds the light dims. To ensure constant lighting, you need to use a voltage stabilizer or install a powerful generator.

These devices are compact and can easily find a place on the body of a motor cultivator. To connect a non-standard one, you will need to make an additional bracket. It is assembled from a steel angle on the frame of the car.

Battery powered lighting

You can make light on a walk-behind tractor without a generator using the installation battery at 12 V. The power source is a battery from a motorcycle, moped or boat. Don't give up on your car battery. If you put a heavy power source on the cultivator, you can solve several related problems - equip the unit with an electric starter and significantly make its body heavier. In addition, it would be useful to be able to illuminate the area at night without the engine running. This function can be useful on a picnic or night fishing.

Installing the headlight on a walk-behind tractor using a battery is carried out in the following sequence:

1. Arrangement of the frame for the power source. It is best to use a steel corner for this. The frame should be attached directly to the frame of the motor-cultivator body. After lowering the battery into the niche, it is firmly secured in it using steel straps.
2. Attaching a lantern and auxiliary lights. The headlight is placed on the walk-behind tractor so that it illuminates the widest possible sector without blinding the operator or oncoming vehicles. It is better to choose devices with an adjustable beam angle.
3. Location electric cable in corrugation along the body of the unit. Installation and connection of control devices. Tester checking the correct assembly of the electrical system.
4. Connecting the wire to the battery terminals, leading the wire to mounting box. Connecting wires to the switch, insulating joints, joints and twists.

In order for the battery capacity to last for a long time, you need to insert LED bulbs. They consume a small amount of energy, creating bright lighting.

If the battery is not located under the standard hood of the walk-behind tractor, then it is necessary to make a separate casing. To do this, you can take a piece of thick plastic and give it the required form and screw it to homemade stands on the frame.

When deciding to install a battery, you should consider the issue of recharging it. This will require purchasing charger or installing an electric generator on a motor cultivator.
