Small Agricultural Crawler Tractors

When the crawler transporter encounters the dilemma of insufficient power on the muddy road, it must be comprehensively investigated and effectively solved from a number of key and detailed angles. First, the tension of the track plays a decisive role in power transmission. As a key component for vehicle to contact with the ground and achieve power transmission, if the tension of the track is wrong, it is easy to slip in the special environment of muddy road with very low adhesion coefficient. Once the track slips, the valuable power output of the engine through the complex transmission system cannot be smoothly and efficiently transmitted to the ground, which will undoubtedly directly lead to a lack of vehicle power, slow driving, stagnation and even serious conditions such as trapped cars. Therefore, the first task at this time is to use professional measuring tools, such as track tension measuring instrument, in strict accordance with the detailed operation process and standard values specified in the vehicle manual, accurately check the tension of the track, and adjust it to a reasonable range.
The condition of the tires (if the vehicle is equipped with tires) is also an important factor that cannot be ignored. The depth of the tire pattern is closely related to the size of the friction between the tire and the ground, in the case of the muddy road itself is unusually wet, when the tire pattern is seriously worn due to long-term use, the friction between the tire and the muddy ground will be sharply reduced. This makes it difficult for the vehicle to get enough grip during the driving process, and it is extremely easy to get stuck in the mud and cannot move. Therefore, in this case, the operator needs to use a special tire pattern depth measuring ruler to carefully check the tire pattern depth. Once it is found that the degree of wear has seriously affected the normal traffic capacity of the vehicle on the muddy road, in order to ensure that the vehicle can successfully complete the transportation task, it should be determined to consider timely replacement of tires that meet the specifications of the vehicle and the use of environmental requirements.
The working state of the engine intake system also has a decisive impact on the power output. In a muddy environment, the air is often mixed with a large number of suspended dust and water vapor, and the air filter, as the core key component of the intake system, is easily blocked by these impurities. Once the air filter is blocked, the amount of air entering the engine will be significantly insufficient, which will directly lead to the fuel in the engine can not be fully mixed with sufficient air and achieve complete combustion, and eventually will inevitably cause the engine power to decline. Therefore, the operator must develop a good habit of regularly checking the air filter, if the air filter is found to be blocked during the inspection process, professional cleaning tools should be quickly used, such as compressed air spray gun, special cleaning agents, etc., to thoroughly clean it. For those who are clogged seriously and can not restore the normal filter function after conventional cleaning means, a new filter must be replaced in time to ensure that the engine intake is always smooth, continue to maintain good power performance, and ensure that the vehicle can also run stably on the muddy road.

When the tracked transporter needs to be parked for a long time, a series of proper and comprehensive maintenance measures are the key to ensure that its subsequent normal and stable use. First of all, the careful choice of storage environment is crucial. The vehicle should be parked in a dry, well-ventilated dedicated area, preferably an indoor garage or a covered parking area. The wet environment is like the invisible killer of the vehicle, which is easy to cause the rust and corrosion of the metal parts of the vehicle, from the body frame to various mechanical parts, will gradually be damaged under the wet erosion; Electronic components will also be affected by moisture and short circuit, failure and other problems, seriously affecting the normal operation of the vehicle's electrical system. The good ventilation environment can effectively reduce the odor caused by long-term closure in the car, inhibit the breeding of microorganisms such as mold, and create a relatively healthy storage environment for the vehicle.
In order to prevent the inner wall of the tank from rusting, the fuel tank must be filled with high-quality fuel oil. At the same time, adding an appropriate amount of fuel stabilizer in line with the requirements of the vehicle fuel system can play a huge role in this small measure, which can effectively avoid the deterioration of the fuel such as oxidation and decomposition during the long standing process. Once the fuel deteriorates, it will not only greatly affect the starting performance of the engine, resulting in difficulty in starting or even unable to start, but also may cause serious corrosion and damage to precision components such as oil pumps and fuel injectors in the fuel system, greatly increasing the maintenance cost and difficulty.
The maintenance of the engine is the most important and must not be ignored. After standing for a long time, the old oil in the engine will gradually decrease its lubrication performance due to the lack of flow and circulation, and it can not provide good protection and lubrication for the various components inside the engine as normal use. Therefore, before parking for a long time, it is best to replace the engine oil with a new, high-quality oil in advance. The new oil has better fluidity, lubricity and oxidation resistance, and can quickly form an effective lubricating film on the surface of each component when the engine starts again, greatly reducing the wear of the start moment and extending the service life of the engine.
The track in a tight state for a long time is easy to cause its internal structure deformation, which affects its service life and vehicle performance. Therefore, during the long parking period, it is necessary to use professional tools, such as track tensioning adjustment devices, in accordance with the guidance of the vehicle manual, carefully relax the track and reduce its internal stress. In addition, if conditions permit, the vehicle cover on the quality of reliable dust cover is a very good choice. The dust cover can not only effectively prevent dust, leaves, bird droppings and other debris from accumulating on the surface of the vehicle, avoid scratching and corrosion of the car paint and body, but also prevent dust from entering the various systems and components inside the vehicle, reduce the difficulty and workload of subsequent cleaning work, and better maintain the overall performance of the vehicle.

In the process of driving the crawler transport vehicle, by taking a series of reasonable and scientific operation and planning measures, it can effectively reduce the damage to the road surface. Maintaining a constant speed is one of the key points. The two kinds of improper operation, rapid acceleration and sudden braking, will make the vehicle instantly produce a strong impact force, and this impact will be directly transmitted to the road through the track, causing serious damage to the road. For example, in the rapid acceleration, the friction between the track and the road will increase in a very short period of time, this sudden increase in friction may cause the surface material of the road, such as asphalt layer, cement mortar layer, etc., by strong pull and loose, fall off; When braking sharply, the braking force of the track will make the road withstand huge pressure, especially in the area where the braking point is concentrated, the road is easy to wear, deformation and even crack and other damage.
It is also very important and necessary to choose a reasonable driving route according to the road conditions. It is necessary to avoid soft and fragile road areas as much as possible, such as the new asphalt road that has just been laid, the road material is still in the process of curing and forming, and has not fully reached the designed compressive strength, and the compressive strength is weak; When the thin cement pavement is under greater pressure, it is easy to crack or even break because of its limited structural strength. If you have to pass through these easily damaged roads due to the needs of transportation tasks, you can lay a suitable backing plate between the track and the road, such as hard wood, high-strength steel plate, etc. The function of the cushion plate is to effectively increase the contact area between the track and the road surface. According to the principle of pressure, when the pressure is unchanged, the contact area increases, the pressure borne by the unit area will decrease, so that the pressure of the track on the road surface will be evenly dispersed, and then the damage degree of the road surface will be significantly reduced, and the integrity and service life of the road surface will be protected.

The difficulty in starting the engine of crawler transporter is a complicated problem involving many factors. Low battery power is a common cause. When the vehicle is not used for a long time, the battery will inevitably have a natural discharge phenomenon, and its power will gradually decrease over time. In the process of use, if there is improper use, such as the use of lighting, audio, air conditioning and other electrical equipment in the car for a long time when the engine is not started, it will consume excessive battery power, and it will also lead to battery loss. When the battery power is insufficient, it can not provide enough starting current, so that the starter can not get enough electric energy to drive, it can not work properly, resulting in difficulty in starting the engine. At this time, the operator can use a professional charger to charge the battery according to the instructions for the use of the charger and the specifications of the battery. If it is found after testing that the battery is seriously aging, the internal plate is damaged, the electrolyte is dried up, etc., even after charging, it is still unable to meet the power and voltage requirements required for the engine to start, it is necessary to replace the new battery for the vehicle in time.
A failure of the fuel system can also make it difficult to start the engine. The function of the fuel filter is to filter impurities in the fuel to ensure that pure fuel enters the engine to participate in combustion. If the fuel filter is blocked by impurities, the flow of fuel will be seriously hindered, and it can not be normally supplied to the engine combustion chamber according to the working needs of the engine, resulting in the engine failing to start. As a key power component in the fuel system, the working state of the oil pump directly affects the normal transmission of fuel. For example, the internal parts of the oil pump wear due to long-term use, resulting in excessive clearance, or aging and damaged seals, which will make the oil pump unable to establish enough pressure to transport fuel. Once there is a problem with the fuel system, the operator needs to use professional tools to check and clean the fuel filter in a timely manner. For the damaged oil pump, it should be removed in a timely manner for maintenance or replacement of a new oil pump to ensure that the fuel system can work normally and provide a stable and sufficient fuel supply for the engine.
As a key component of engine ignition system, the performance of spark plug directly affects the ignition effect. During the long-term use of spark plugs, the electrode surface will gradually accumulate carbon, the existence of carbon deposits will increase the resistance between the electrodes, resulting in the weakening of ignition energy; With the increase of use time, the spark plug electrode will also wear, and the ignition ability will decrease. When the ignition energy is insufficient, the combustible mixture in the engine can not be ignited in time and effectively, resulting in the difficulty of starting the engine. In this case, the operator can carefully disassemble the spark plug and use special spark plug cleaning tools, such as spark plug carbon cleaning agent, wire brush, etc., to clean up the carbon deposit; If it is found after inspection that the spark plug is aging seriously, the electrode wear is excessive, the gap is too large or too small, etc., and it can not meet the normal ignition needs, it should be replaced in time with a new spark plug that meets the engine model and performance requirements.
At low temperatures, engine starting difficulties are more common and complex. Low temperature will make the oil viscosity increase sharply, the fluidity becomes worse, resulting in the engine at start, the movement resistance between the components significantly increased, difficult to smooth rotation. At the same time, low temperature may also cause the solidification of fuel, affecting the normal injection and atomization effect of fuel, so that the combustible mixture can not form a good combustion condition in the cylinder. In order to solve these problems, it is necessary to use the engine preheater to preheat the engine before starting the engine in a low temperature environment. The engine preheater can increase the internal temperature of the engine by heating the engine coolant or oil, reduce the resistance between parts, and also help the normal injection and atomization of fuel. In addition, according to the specific temperature of the low temperature environment, the oil and fuel suitable for the low temperature environment should be replaced. Low temperature oil has better low temperature fluidity and can quickly reach various lubricating parts at low temperatures; Low-temperature fuel has a lower freezing point and can maintain a good liquid state at low temperatures, ensuring that the engine can start and operate smoothly at low temperatures.
