Engine for tiller. an important and integral unit of agricultural equipment. The technical characteristics of the motor are determined by the functionality, ease of use, reliability, compatibility with attachments, and the ability of the device to perform its tasks. The power unit must have the required performance, good lifespan and the necessary power reserve. The device, equipped with the high-quality power unit, makes life easier for summer residents, gardeners, and farmers.
Types of engines.
For installation on gardening equipment and heavy agricultural equipment used gasoline and diesel engines. The first ones are distinguished by high productivity and ability to work in difficult operating conditions, and the second ones are universal and economical. Engine tiller, working on diesel fuel, supports a large number of types of attachments. The best production effect is achieved when operating at low speeds.
Such units have a useful lifespan and high resistance to adverse weather and climate factors. The most famous. two-cylinder models. They are relatively inexpensive and tolerate elevated temperatures. When using such a motor in the summer heat enough of the most straightforward air cooling system. Petrol modifications require high operating costs for maintenance, maintenance, and operation. Their advantages are durability and reliability.
The four-stroke engine of this type has high performance and the ability to work on heavy soils. A unit equipped with a vertical shaft saves time because it can operate stably at high speeds.
Power units compatible with tiller are classified according to the starting method:
- on electric;
- on hand;
- on combined.
The manual drive is found in the most budget and outdated models. common units with electric starting, providing an easy and quick start technology. They are economical, easy to operate, and reliable. Using an electric motor for a tiller is appropriate at the cottage or in your garden. Combined modification is a convenient option. This functional scheme is based on 4-stroke motors designed for processing large areas of arable land and agricultural land.
They greatly facilitate the task of the operator because they allow you to choose a convenient type of launch. Both petrol and diesel models are equipped with an automatic speed regulator. Another classification feature is power. Lightweight tillers (less than 70 kg) set the engines to 4 liters. On medium (71-100 kilograms) motors, up to 7 liters are used. For collaboration with heavy (over 100 kg) equipment used power units from 8 liters. The power limit is set at 16 liters.
In light and medium tillers, two-stroke gasoline or diesel engines with an air-cooling system are used. They are well suited for chores in a private house. Among farmers, the most widespread are heavy tillers equipped with a 4-stroke motor with a forced liquid cooling mechanism. Depending on the modification, the engine is completed with a gear, chain or worm gearbox. The latter may have a V-belt or bevel gear.
The market assortment has a large number of engines from Chinese, Japanese, American, and European manufacturers. This compact devices designed for use in the dacha economy, and overall heavy units, focused on field work. The most common models among domestic consumers are:
Highly valued and American Greenfield, which has the best value for money. Good engines are made by domestic manufacturers. Such units are reliable, relatively cheap, functional, and versatile. For example, the subcompact UD-2 engine is suitable for garden mini tractors and autonomous electric generators. Modifications intended for installation on light and medium tillers are equipped with an air cooling system and a dust filter that prevents solid particles from clogging the parts.
Another example of domestic engineering technology is the Sadko engine. A non-standard design solution in its manufacture is the use of a light aluminum alloy body material. Such motors are considered the best option for gardening equipment. The device does not create a significant load on the hands of the operator and has a compact size.
Stiffeners located around the perimeter of the hull contribute to the stability of the tiller and provide good resistance to internal pressure, which occurs during the combustion of the fuel mixture. Despite its low weight, Cadc motors maintain heavy loads and can operate under adverse weather conditions. Many domestic consumers prefer Japanese engines.
The advantages of such mechanisms:
- Compliance with international standards.
- Sophisticated design.
- High performance.
- Use of advanced technology and materials of exceptional quality.
- Compatible with a large number of attachments.
A typical indicator of the power of Japanese engines. 7 liters. with. They are suitable for installation both on the tiller and on pumps, generators, lawn mowers, and other garden equipment. Magnum brand gasoline engines are the best choice for handling large tracts of land. Recommended area is 5000 m². Such motors are aggregated with a plow, hiller, potato planter, motor pump, trailer, high pressure cleaner and other types of attachments.
What engine to choose for tiller?
When choosing a motor to tiller it is necessary to consider:
- anticipated operating conditions;
- mounting versatility;
- constructive compatibility with the existing model of agricultural equipment;
- declared by the manufacturer engine resource.
This important node must comply with the chassis and transmission equipment, well correlated with the dimensions. Attention should be paid to the presence of a lighting coil, which will allow you to connect the headlights for use of the unit in the dark.
Specifications and functional parameters that should be taken into account:
- Departure shaft. The optimal and most common modification is a 19 mm or 20 mm key. Slightly inferior in-demand units with the output of the slotted type. Less common models of conical design.
- Existence of the sensor of control of the level of oil with which all motors, except extrabudgetary, are equipped. Such an indicator is a guarantee of motor durability.
- Universal mount designed to provide ease of installation of the engine.
- Air filter double cleaning or with an oil bath. The second option is easier to maintain. It is compatible with tiller with low ground clearance. Well protects the mechanism from the penetration of soil dust and particulate matter.
- Motor Resource. It is advisable to choose a motor with a rating of at least 3000 m / h.
Many models have integrated speed control. When the load changes, the mechanism independently determines the rotational moment, which increases production efficiency and saves fuel. It is advisable to choose a gasoline engine or diesel unit equipped with such a device. Tiller and TATA with a productive power plant and automatic clutch are in great demand. They are made of first-class wear-resistant materials that can resist overheating and precipitation for a long time.
Such equipment is recommended to choose to work on large areas of land, heavy soils, and in severe operating conditions. For the processing of private agricultural land, its garden, and local area suitable engine from China, for example, the production company Lifan. These are compact and functional units that can be used in various business operations. Due to the relatively low cost of such power plants are available to a wide range of buyers.
The similar engine is equipped with the two-valve drive. In motors, Lifan is used air cooling exclusively, due to the scope of the units. An excellent domestic equivalent for use in a household or on a small farm is tiller and Oka, produced at the Kaluga engine plant. To control this compact device, the operator will not need to exert great physical effort. The equipment comes with a powerful but economic power plant.
The tiller and the Oka are equipped with an adjustable steering column. They are distinguished by a narrow body, an acceptable price, and cable control. If you need a weighted model for arable work, you can choose an inexpensive, but high-quality Belarusian equipment, such as MDZ-12. This tiller comes with a powerful 12-horsepower gasoline engine. Structurally, it is arranged on the same axis, which ensures optimal balancing and maneuverability of the unit.
Tiller engine repair.
Like any equipment, tiller needs timely service: oil change, cleaning, engine adjustment, etc. The power plant, which is the most complex component of agricultural equipment, is prone to failure. Often, you can repair the unit with your own hands. An appropriate set of tools and knowledge of the fundamentals of a tiller engine device are required. An instruction is attached to the equipment, which describes the procedure for disassembling and assembling the assembly.
It makes the task somewhat easier. If the engine runs intermittently, then first you need to check the level of the fuel mixture in the tank. Diesel and gasoline engines have a different operational resource. For the former, the typical figure is 4,000 m / h, while the latter is capable of producing half as much. The reasons for their failure are more due to the increased power, which leads to rapid wear of parts and functional elements of the structure. Often there is a malfunction of the electric starter switch.
All engine failures for agricultural equipment fall into two broad categories:
- Startup problems.
- Functional failures.
There are also common problems with the variable speed drive, a mechanism that transmits torque and is capable of smoothly changing the gear ratio in the range of the provided regulation. A thorough diagnosis must precede repair. Minor faults can be identified during routine maintenance.
Valve adjustment is an important and necessary procedure designed to ensure reliable operation of the mechanism and increase its operating life. Therefore, it should be carried out at intervals established by the manufacturer.
The following tools are needed:
- set of wrenches;
- crosswise and flat screwdrivers;
- thin probe
Some models may require other hand tools. The point of the adjustment process is to set the tiller engine valve gaps to the desired value, which is indicated in the user manual. Neglect of this operation is a common cause of premature failure of the motor. In the most common models, the intake valve clearance is 0.15 mm, exhaust. 0.2. It is installed by turning the lock nut. If the probe fits freely, the clearance is adjusted correctly.
Common failures. problems with the supply of the fuel mixture. If the engine smokes or does not start, check the spark plugs. Malfunctions in the fuel supply system may be the answer to the question of why the engine shoots or does not develop speed. If the test reveals that the spark plugs are dry, the cause of the problems should be sought in the fuel supply system to the cylinders.
To solve the problem, you must perform the following steps:
- Fill the tank with fresh gasoline or diesel.
- Unscrew the fuel cock.
- Clean the drain plug in the reservoir plug.
- Disconnect the fuel hose from the inlet fitting at the attachment point to the carburetor.
- Blow out the jets.
If the fuel enters the carburetor but does not reach the cylinders, an increased vibration will be felt when trying to start the engine. The problem is solved by disassembling and cleaning the site. It is necessary to blow the carburetor pump. It happens that the engine does not start from an excess of fuel. A sign of such a problem is a wet candle. It is corrected by cleaning the cylinders and pumping the motor. You must first turn off the fuel supply.
If plaque is detected on the candle, it is necessary to clean it and check the gap between the electrodes. It should be at 0.8 mm. Need to check and the presence of a spark. Its absence indicates a possible fault in the electrical circuit. A common problem is a large gap between the coil winding and the magnetic core.
If the engine is powered by an electric starter, the reason for the lack of start may be:
- battery discharge;
- bad starter;
- blown fuse.
If the engine starts, but does not develop speed, stalls or works intermittently, the causes may be the following problems:
- Clogged air filter.
- The deposition in the silencers of combustion products of the fuel mixture.
- Incorrect carburetor setting.
- Worn parts piston group.
Compression should be 8 atm. This indicator is checked by connecting a special measuring tool. a pressure meter to the plug hole. The diagnostic procedure consists in turning the shaft with a starter. If the motor does not stop, check the operation of the switch. In case of need, contacts are cleared, or the faulty element is changed.
How to remove the engine from tiller?
To dismantle the power plant tiller is placed on a flat surface and cleaned of contamination. The protective shield is removed, the accelerator cable is disconnected from the carburetor plate. Then release the bolts that secure the mounting bracket for mounting the attachment, loosen the restrictive pins of the drive belt. Unscrew the four screws that secure the engine. The motor turns to the left.
The belt is removed from the crankshaft pulley. After that, the power plant is considered to be disconnected from the chassis. If necessary, fasteners can be replaced. In some models, to facilitate access to the bolts that fix the motor on agricultural equipment, the wings are pre-removed.
Installing the engine on the tiller, you need to be careful and follow the sequence of actions. Errors will lead to a decrease in the operating life of the unit, rapid wear of parts and will cause problems.
The following conditions must be met:
- correctly transfer the torque from the power plant to the transmission;
- accurately attach the motor to the gearbox or tiller frame;
There are special installation kits that help avoid errors when assembling equipment.
Such kits consist of the following parts:
- Adapter plate. Inserted between the engine and gearbox.
- Hubs. Installed on the crankshaft of the motor.
- Fasteners. Provide reliable fixation of the power plant.
When using such a kit, you need to perform a sequence of two actions. fix the motor on the mounting plate and put the pulley on the crankshaft. With this kit, it is easy to install the engine on a tiller, both domestic and foreign.
